++.UE
++\&: translation, reflection, scaling,
++rotation, and shearing/skewing. However, \fBpamhomography\fP additionally can
++do \fIbilinear\fP transforms, which means it can warp any quadrilateral to any
++other quadrilateral, even when this mapping cannot be described using a single
++set of linear equations. This can be useful, for example, for creating
++perspective views of rectangular images or for reverse-mapping a perspective
++view back to a rectangular projection.
++
++
++.UN OPTIONS
++.SH OPTIONS
++.PP
++In addition to the options common to all programs based on libnetpbm (most
++notably \fB-quiet\fP, see 
++.UR http://index.html#commonoptions
++Common Options
++.UE
++\&), \fBpamhomography\fP recognizes the following command line
++options:
++
++
++
++
    \fB-from\fP=\fIcoords\fP
++.sp
++This defines the source quadrilateral. \fIcoords\fP is a list of four
++  integer-valued (\fIx\fP, \fIy\fP) coordinates. If you do not
++  specify \fB-from\fP, the source quadrilateral is taken to be the four
++  corners of the input image in clockwise order, starting from the upper
++  left.
++
++
++
    \fB-to\fP=\fIcoords\fP
++.sp
++This defines the target quadrilateral. \fIcoords\fP is a list of four
++integer-valued (\fIx\fP, \fIy\fP) coordinates. If you do not
++specify \fB-to\fP, the target quadrilateral is taken to be the four corners
++of the input image in clockwise order, starting from the upper left.
++
++
++
    \fB-mapfile\fP=\fImap_file\fP
++.sp
++This names a text file that describes the mapping from the source to the
++target quadrilateral. The file \fImap_file\fP must contain either eight
++integer-valued (\fIx\fP, \fIy\fP) coordinates, being the four source
++coordinates followed by the corresponding four target coordinates, or only
++four (\fIx\fP, \fIy\fP) coordinates, being only the four target
++coordinates. In the latter case, the source quadrilateral is taken to be the
++four corners of the input image in clockwise order, starting from the upper
++left.
++
++
++
    \fB-view\fP=\fIcoords\fP
++.sp
++This defines the target view. \fIcoords\fP is a list of two integer-valued
++(\fIx\fP, \fIy\fP) coordinates: the upper left and lower right boundaries,
++respectively, of the pixels that will be visible in the output image. If
++\fB-view\fP is not specified, the target view will fit precisely the target
++quadrilateral.
++
++
++
    \fB-fill\fP=\fIcolor\fP
++.sp
++This is the color with which the program fills all pixels that lie outside
++of the target quadrilateral. Specify the color as described for the
++.UR http://libnetpbm_image.html#colorname
++ argument of the pnm_parsecolor() library routine
++.UE
++\&.
++.sp
++The default is black, and for images with a transparency plane, transparent.
++
++
++
++.PP
++Cooordinates should normally be specified in clockwise order. The syntax is
++fairly flexible: all characters other than the plus sign, minus sign, and
++digits are treated as separators. Although coordinates need to be integers,
++they may lie outside the image's boundary.
++.PP
++If you specify \fB-mapfile\fP along with \fB-from\fP and/or \fB-to\fP,
++\fB-from\fP and \fB-to\fP override the quadrilaterals specified
++by \fImap_file\fP.
++
++
++.UN PARAMETERS
++.SH PARAMETERS
++.PP
++\fBpamhomography\fP's only parameter, \fIpam_file\fP, is the name of the
++  file containing the input image. If you don't specify \fIpam_file\fP, the
++  image comes from Standard Input.
++
++  
++.UN NOTES
++.SH NOTES
++.PP
++The output image uses the same Netpbm format as the input image.
++.PP
++Simple transformations are best handled by other Netpbm programs, such as
++those listed in the 
++.UR #SEE-ALSO
++\&'SEE ALSO'
++.UE
++\& section
++below. Use \fBpamhomography\fP for more sophisticated transformations such as
++perspective adjustments, rotations around an arbitrary point in the image,
++extraction of non-rectangular quadrilaterals, shearings by coordinates rather
++than by angle, and, in general, all transformations that are most easily
++expressed as mapping four points in one image to four points in another
++image.

++The first example showcases the real power of bilinear transformations.
++Assuming \fIpark_row_rect.map\fP has the following contents:
++
++.nf\f(CW    (147, 51) (316, 105) (402, 595) (92, 560)

++.PP
++projects the building's facade from a perspective view to a rectilinear
++front-on view. Remember that \fBpamhomography\fP ignores the parentheses and
++commas used in \fIpark_row_rect.map\fP; they merely make the file more
++human-readable. We equivalently could have written
++
++.nf\f(CW    147 51 316 105 402 595 92 560 0 0 440 0 440 639 0 639\fP

++\fBpamhomography\fP can warp the image to a trapezoid to make it look like
++it's leaning backwards in 3-D:
++

++.PP
++As a very simple example,
++
++.nf\f(CW    pamhomography -to '440,0 0,0 0,639 440,639' park_row.ppm > park_row_flip.ppm\fP
    
++.PP
++flips the image left-to-right. Note that in this case the target
++quadrilateral's coordinates are listed in counterclockwise order because
++that represents the correspondence between points (0, 0) ↔ (440, 0) and
++(0, 639) ↔ (639, 0).
++.PP
++Scaling is also straightforward. The following command scales down the
++image from 441×640 to 341×540:
++
++.nf\f(CW    pamhomography -to '0,0 340,0 340,539 0,539' park_row.ppm > park_row_small.ppm\fP
    ++.PP ++Let's add 100 pixels of tan border to the above.

    ppmtompeg produces an MPEG-1 video stream.  MPEG-1 is the
+-first great video compression method, and is what is used in Video CDs
+-(VCD).  ppmtompeg originated in the year 1995.  DVD uses a more
+-advanced method, MPEG-2.  There is an even newer method called MPEG-4
+-which is also called Divx.  I don't know where one finds that used.
+-
+-
    There's technically a difference between a compression method for
+-video and an actual file (stream) format for a movie, and I don't know
+-if it can be validly said that the format of the stream
+-ppmtompeg produces is MPEG-1.
+-
+-
    Mencoder from the Mplayer
+-package is probably superior for most video format generation
+-needs, if for no other reason than that it is more popular.
+-
+-
    The programming library PM2V
+-generates MPEG-2 streams.
+-
+-
    Use Mplayer (not part of Netpbm)
+-to do the reverse conversion: to create a series of PNM files from an MPEG
+-stream.
+-
+-
    param_file is a parameter file which includes a list of
+-input files and other parameters.  The file is described in detail
+-below.
+-
+-
    To understand this program, you need to understand something about
+-the complex MPEG-1 format.  One source of information about this
+-standard format is the section Introduction to MPEG in the Compression FAQ.
+-
+-
    OPTIONS
    
+-
+-
    The -gop, -combine_gops, -frames, and
+--combine_frames options are all mutually exclusive.
+-
+-
    
+-
    -stat stat_file
+-
+-
    This option causes ppmtompeg to append the statistics that
+-it write to Standard Output to the file stat_file as well.  The
+-statistics use the following abbreviations: bits per block (bpb), bits
+-per frame (bpf), seconds per frame (spf), and bits per second (bps).
+-
+-
    These statistics include how many I, P, and B frames there were,
+-and information about compression and quality.
+-
+-
+-
    -quiet num_seconds
+-
+-
     causes ppmtompeg not to report remaining time more often
+-than every num_seconds seconds (unless the time estimate rises,
+-which will happen near the beginning of the run).  A negative value
+-tells ppmtompeg not to report at all.  0 is the default
+-(reports once after each frame).  Note that the time remaining is an
+-estimate and does not take into account time to read in frames.
+-
+-
    -realquiet 
     causes ppmtompeg to run silently,
+-with the only screen output being errors.  Particularly useful when
+-reading input from stdin.  The equivalent of the -quiet
+-common option of most other Netpbm programs.
+-
+-
    
+--no_frame_summary
+-
+-
     This option prevents ppmtompeg from printing a summary
+-line for each frame
+-
+-
    -float_dct
+-
+-
     forces ppmtompeg to use a more accurate, yet more
+-computationally expensive version of the DCT.
+-
+-
    -gop gop_num
+-
    
+-causes ppmtompeg to encode only the numbered GOP (first GOP is 0).  The
+-parameter file is the same as for normal usage.  The output file will be
+-the normal output file with the suffix .gop.gop_num.
+-ppmtompeg does not output any sequence information.
+-
+-
    -combine_gops
+-
+-
     causes ppmtompeg simply to combine some GOP files into a
+-single MPEG output stream.  ppmtompeg inserts a sequence header
+-and trailer.  In this case, the parameter file needs only to contain 
+-the SIZE value, an output file, and perhaps a list of input GOP
+-files (see below).
+-
+-If you don't supply a list of input GOP files is used, then
+-ppmtompeg assumes you're using the same parameter file you used
+-when you created the input (with the -gop option) and
+-calculates the corresponding gop filenames itself.  If this is not the
+-case, you can specify input GOP files in the same manner as normal
+-input files -- except instead of using INPUT_DIR, INPUT, and
+-END_INPUT, use GOP_INPUT_DIR, GOP_INPUT, and GOP_END_INPUT.  If no
+-input GOP files are specified, then the default is to use the output
+-file name with suffix .gop.gop_num, with gop_num
+-starting from 0, as the input files.
+-     
+-
    Thus, unless you're mixing and matching GOP files from different
+-sources, you can simply use the same parameter file for creating the
+-GOP files (-gop) and for later turning them into an MPEG stream
+-(-combine_gops).
+-     
+-
+-
    -frames first_frame last_frame
+-
+-
    This option causes ppmtompeg to encode only the frames numbered
+-first_frame to last_frame, inclusive.  The parameter
+-file is the same as for normal usage.  The output will be placed in
+-separate files, one per frame, with the file names being the normal
+-output file name with the suffix .frame.frame_num.  No
+-GOP header information is output.  (Thus, the parameter file need not
+-include the GOP_SIZE value)
+-
+-
    Use ppmtompeg -combine_frames to combine these frames later into
+-an MPEG stream.
+-
+-
+-
    -combine_frames
+-
+-
     This option causes ppmtompeg simply to combine some
+-individual MPEG frames (such as you might have created with an earlier
+-run of ppmtompeg -frames) into a single MPEG stream.  Sequence
+-and GOP headers are inserted appropriately.  In this case, the
+-parameter file needs to contain only the SIZE value, the GOP_SIZE
+-value, an output file, and perhaps a list of frame files (see below).
+-
+-
    The parameter file may specify input frame files in the same manner
+-as normal input files -- except instead of using INPUT_DIR, INPUT, and
+-END_INPUT, use FRAME_INPUT_DIR, FRAME_INPUT, and FRAME_END_INPUT. If
+-no input frame files are specified, then the default is to use the
+-output file name with suffix .frame.frame_num, with
+-frame_num starting from 0, as the input files.
+-     
+-
+-
+-
    -nice
+-
+-
    This option causes ppmtompeg to run any remote processes
+-"nicely," i.e.  at low priority.  (This is relevant only if you are
+-running ppmtompeg in parallel mode.  Otherwise, there are no
+-remote processes).  See 'man nice.'
+-
+-
    -max_machines num_machines
+-
+-
    This option causes ppmtompeg to use no more than
+-num_machines machines as slaves for use in parallel encoding.
+-
+-
    -snr 
+-
+-
    This option causes ppmtompeg to include the signal-to-noise
+-ratio in the reported statistics.  Prints SNR (Y U V) and peak SNR (Y
+-U V) for each frame.  In summary, prints averages of luminance only
+-(Y).  SNR is defined as 10*log(variance of original/variance of
+-error).  Peak SNR is defined as 20*log(255/RMSE).  Note that
+-ppmtompeg runs a little slower when you use this option.
+-
+-
    -mse
+-
+-
    This option causes ppmtompeg to report the mean squared
+-error per block.  It also automatically reports the quality of the
+-images, so there is no need to specify -snr then.
+-
+-
    -bit_rate_info rate_file
+-
+-
     This option makes ppmtompeg write bit rate information
+-into the file rate_file.  Bit rate information is bits per frame, and
+-also bits per I-frame-to-I-frame.
+-
+-
    -mv_histogram 
+-
+-
     This option causes ppmtompeg to print a histogram of the
+-motion vectors as part of statistics.  There are three histograms --
+-one for P frame, one for forward B frame, and one for backward B frame
+-motion vectors.
+-
+-
    The output is in the form of a matrix, each entry corresponding to one
+-motion vector in the search window. The center of the matrix
+-represents (0,0) motion vectors.
+-
+-
    -debug_sockets
+-
+-
    This option causes ppmtompeg to print to Standard Output
+-messages that narrate the communication between the machines when you run
+-ppmtompeg in parallel mode.
+-

+-     
+-
    
+-
+-
    PARAMETER FILE
    
+-
+-
    The parameter file must contain the following
+-lines (except when using the -combine_gops or -combine_frames
+-options):
+-
+-
    
+-
+-
    PATTERN pattern
+-
+-
    This statement specifies the pattern (sequence) of I frames, P frames,
+-and B frames.  pattern is just a sequence of the letters I, P, and
+-B with nothing between.  Example:
+-
+-
    +-    PATTERN IBBPBBPBBPBBPBB
+-
         
+-
+-
    See I Frames, P Frames, B Frames.
+-
+-
    OUTPUT output file
+-
    This names the file where the output MPEG stream goes.
+-     
+-
    INPUT_DIR directory
+-
+-
    This statement tells where the input images (frames) come from.
+-If each frame is in a separate file, directory is the directory
+-where they all are.  You may use . to refer to the current 
+-directory.  A null directory refers to the root directory of the
+-system file tree.
+-
+-
    To have ppmtompeg read all the frames serially from Standard 
+-Input, specify
+-
    +-    INPUT_DIR stdin
+-
    
+-
+-
    INPUT
+-
    
+-This line must be followed by a list of the input files (in display order)
+-and then the line END_INPUT.
+-
+-
    There are three types of lines between INPUT and END_INPUT.  First,
+-a line may simply be the name of an input file.  Second, the line
+-may be of the form single_star_expr
+-[x-y].
+-single_star_expr can have a single * in it.  It is
+-replaced by all the numbers between x and y inclusive.  So, for
+-example, the line tennis*.ppm [12-15] refers to the files
+-tennis12.ppm, tennis13.ppm, tennis14.ppm, tennis15.ppm.
+-
+-
    Uniform zero-padding occurs, as well.  For example, the line
+-football.*.ppm [001-130] refers to the files football.001.ppm,
+-football.002.ppm, ..., football.009.ppm, football.010.ppm, ...,
+-football.130.ppm.
+-
+-
    The third type of line is: single_star_expr
+-[x-y+s], where the
+-line is treated exactly as above, except that we skip by s.  Thus, the
+-line football.*.ppm [001-130+4] refers to the files
+-football.001.ppm, football.005.ppm, football.009.ppm,
+-football.013.ppm, etc.
+-
+-
    Furthermore, a line may specify a shell command to execute to
+-generate lines to be interpreted as described above, as if those lines
+-were in the parameter file instead.  Use back ticks, like in the
+-Bourne Shell, like this:
+-
+-
    +-    `cat myfilelist`

+-If input is from Standard Input (per the INPUT_DIR statement), 
+-ppmtompeg ignores the INPUT/END_INPUT block, but
+-it still must be present.
+-     
+-
      BASE_FILE_FORMAT {PPM | PNM | YUV | 
+-     JPEG | JMOVIE}
+-
+-
      ppmtompeg must convert all input files to one of the
+-following formats as a first step of processing: PNM, YUV, JPEG(v4),
+-or JMOVIE.  (The conversion may be trivial if your input files are
+-already in one of these formats).  This line specifies which of the
+-four formats.  PPM is actually a subset of PNM.  The separate
+-specification is allowed for backward compatibility.  Use PNM instead
+-of PPM in new applications.
+-
+-
      INPUT_CONVERT conversion_command
+-
+-
      You must specify how to convert a file to the base file format.
+-If no conversion is necessary, then you would just say:
+-
+-     
      +-     INPUT_CONVERT *
+-     
      
+-     
+-
      Otherwise, conversion_command is a shell command that causes
+-an image in the format your specified with BASE_FILE_FORMAT to
+-be written to Standard Output.  ppmtompeg executes the command
+-once for each line between INPUT and END_INPUT (which is
+-normally, but not necessarily, a file name).  In the conversion
+-command, ppmtompeg replaces each '*' with the contents of that
+-line.
+-     
+-     If you had a bunch of gif files, you might say:
+-     
      +-     INPUT_CONVERT giftopnm *
+-     
      
+-
+-     If you have a bunch of separate a.Y, a.U, and a.V files (where
+-     the U and V have already been subsampled), then you might say:
+-
+-     
      +-     INPUT_CONVERT cat *.Y *.U *.V
+-     
      
+-
+-
      Input conversion is not allowed with input from stdin, so use
+-
+-     
      +-     INPUT_CONVERT *
+-     
      
+-
+-as described above.
+-     
+-
      SIZE widthxheight
+-
+-
      
+-
+-
      width and height are the width and height of each
+-frame in pixels.
+-
+-
      When ppmtompeg can get this information from the input image
+-files, it ignores the SIZE parameter and you may omit it.
+-
+-
      When the image files are in YUV format, the files don't contain
+-dimension information, so SIZE is required.
+-
+-
      When ppmtompeg is running in parallel mode, not all of the
+-processes in the network have access to the image files, so
+-SIZE is required and must give the same dimensions as the
+-input image files.
+-
+-
      YUV_SIZE widthxheight
+-
+-
      This is an obsolete synonym of SIZE.
+-
+-
      YUV_FORMAT {ABEKAS | PHILLIPS | UCB |
+-                      EYUV | pattern}
+-
+-
      This is meaningful only when BASE_FILE_FORMAT specifies
+-YUV format, and then it is required.  It specifies the sub-format of
+-the YUV class.
+-
+-
+-
      GOP_SIZE n
+-
+-
      n is the number of frames in a Group of Pictures.  Except that
+-because a GOP must start with an I frame, ppmtompeg makes a GOP as
+-much longer than n as it has to to make the next GOP start with an
+-I frame. 
+-
+-
      Normally, it makes sense to make your GOP size a multiple of your
+-pattern length (the latter is determined by the PATTERN parameter file
+-statement).
+-
+-
      See Group Of Pictures.
+-
+-
      SLICES_PER_FRAME n
+-
      n is roughly the number of slices per frame.  Note, at
+-least one MPEG player may complain if slices do not start at the left
+-side of an image.  To ensure this does not happen, make sure the
+-number of rows is divisible by SLICES_PER_FRAME.
+-
+-
      PIXEL {FULL | HALF} 
+-
+-
      use half-pixel motion vectors, or just full-pixel ones It is
+-usually important that you use half-pixel motion vectors, because it
+-results in both better quality and better compression.
+-     
+-
+-
      RANGE n
+-
      Use a search range of n pixels in each of the four directions
+-from a subject pixel.  (So the search window is a square n*2 pixels
+-on a side).
+-
+-
      PSEARCH_ALG {EXHAUSTIVE | TWOLEVEL |
+-     SUBSAMPLE | LOGARITHMIC}
+-
+-
      This statement tells ppmtompeg what kind of search
+-    technique (algorithm) to use for P frames.  You select the desired
+-    combination of speed and compression.  EXHAUSTIVE gives the
+-    best compression, but LOGARITHMIC is the fastest.
+-    TWOLEVEL is an exhaustive full-pixel search, followed by a
+-    local half- pixel search around the best full-pixel vector (the
+-    PIXEL option is ignored for this search technique).
+-
+-
      BSEARCH_ALG {SIMPLE | CROSS2 | EXHAUSTIVE}
+-
+-
      This statement tells ppmtompeg what kind of search
+-    technique (algorithm) to use for B frames.  SIMPLE means
+-    find best forward and backward vectors, then interpolate.
+-    CROSS2 means find those two vectors, then see what backward
+-    vector best matches the best forward vector, and vice versa.
+-    EXHAUSTIVE does an n-squared search and is
+-    extremely slow in relation to the others (CROSS2
+-    is about half as fast as SIMPLE).

      REFERENCE_FRAME {ORIGINAL | DECODED} 
      This
+-statement determines whether ppmtompeg uses the original images
+-or the decoded images when computing motion vectors.  Using decoded
+-images is more accurate and should increase the playback quality of
+-the output, but it makes the encoding take longer and seems to give
+-worse compression.  It also causes some complications with parallel
+-encoding. (see the section on parallel encoding).  One thing you can
+-do as a trade-off is select ORIGINAL here, and lower the
+-qscale (see QSCALE if the quality is not good enough.

    The following lines are optional:
+-
+-
    
+-
+-
    FORCE_ENCODE_LAST_FRAME
+-
+-
    This statement is obsolete.  It does nothing.
+-
+-
    Before Netpbm 10.26 (January 2005), ppmtompeg would drop
+-trailing B frames from your movie, since a movie can't end with a B
+-frame.  (See I Frames, P Frames, B Frames.)
+-You would have to specify FORCE_ENCODE_LAST_FRAME to stop
+-that from happening and get the same function that ppmtompeg
+-has today.
+-
+-
+-
    NIQTABLE
+-
+-
    This statement specifies a custom non-intra quantization table.
+-If you don't specify this statement, ppmtompeg uses a default
+-non-intra quantization table.
+-
+-
    
+-The 8 lines immediately following NIQTABLE specify the quantization
+-table.  Each line defines a table row and consists of 8 integers,
+-whitespace-delimited, which define the table columns.
+-
+-
    IQTABLE
+-
+-
    This is analogous to NIQTABLE, but for the intra quantization table.
+-
+-
    ASPECT_RATIO ratio
+-
+-
    This statement specifies the aspect ratio for ppmtompeg to
+-specify in the MPEG output.  I'm not sure what this is used for.
+-
+-
    ratio must be 1.0, 0.6735, 0.7031, 0.7615, 0.8055, 0.8437,
+-0.8935, 0.9157, 0.9815, 1.0255, 1.0695, 1.0950, 1.1575, or 1.2015.
+-
+-
    FRAME_RATE rate
+-
    This specifies the frame rate for ppmtompeg to specify in the
+-MPEG output.  Some players use this value to determine the playback rate.
+-
+-
    rate must be 23.976, 24, 25, 29.97, 30, 50, 59.94, or 60.
+-
+-
    BIT_RATE rate
+-
    This specifies the bit rate for Constant Bit Rate (CBR) encoding.
+-
+-
    rate must be an integer.
+-
+-
    BUFFER_SIZE size 
+-
+-
    This specifies the value
+-ppmtompeg is to specify in the MPEG output for the Video
+-Buffering Verifier (VBV) buffer size needed to decode the sequence.
+-
+-
    A Video Verifying Buffer is a buffer in which a decoder keeps the
+-decoded bits in order to match the uneven speed of the decoding with
+-the required constant playback speed.
+-
+-
    As ppmtompeg encodes the image, it simulates the decoding
+-process in terms of how many bits would be in the VBV as each frame gets
+-decoded, assuming a VBV of the size you indicate.  
+-
+-
    If you specify the WARN_VBV_UNDERFLOW statement,
+-ppmtompeg issues a warning each time the simulation underflows
+-the buffer, which suggests that an underflow would occur on playback,
+-which suggests the buffer is too small.
+-
+-
    If you specify the WARN_VBV_OVERFLOW statement,
+-ppmtompeg issues a warning each time the simulation overflows
+-the buffer, which suggests that an overflow would occur on playback,
+-which suggests the buffer is too small.
+-
+-
    WARN_VBV_UNDERFLOW
+-
    WARN_VBV_OVERFLOW
+-
+-
    See BUFFER_SIZE.
+-
+-
    These options were new in Netpbm 10.26 (January 2005).  Before that,
+-ppmtompeg issued the warnings always.
+-
+-
    
+-
+-
+-The following statements apply only to parallel operation:
+-
+-
     
+-
+-
    PARALLEL
+-
+-
    This statement, paired with END PARALLEL, is what causes
+-ppmtompeg to operate in parallel mode.  See Parallel Operation.
+-
+-
    END PARALLEL
+-
+-
    This goes with PARALLEL.
+-
+-
    PARALLEL_TEST_FRAMES n 
+-
+-
    The master starts off by measuring each slave's speed.  It does
+-this by giving each slave n frames to encode and noting how
+-long the slave takes to finish.  These are not just test frames,
+-though -- they're real frames and the results become part of the
+-output.
+-ppmtompeg is old and measures time in undivided seconds, so
+-to get useful timings, specify enough frames that it will take at
+-least 5 seconds to process them.  The default is 10.
+-
+-
    If you specify FORCE_I_ALIGN, ppmtompeg will increase
+-the test frames value enough to maintain the alignment.
+-
+-
    If there aren't enough frames for every slave to have the indicated
+-number of test frames, ppmtompeg will give some slaves fewer.
+-
+-
+-
    PARALLEL_TIME_CHUNKS t
+-
+-
    When you specify this statement, the master attempts to feed work
+-to the slaves in chunks that take t seconds to process.  It uses
+-the speed measurement it made when it started up (see PARALLEL_TEST_FRAMES)
+-to decide how many frames to put in the chunk.  This statement obviously
+-doesn't affect the first batch of work sent to each slave, which is the
+-one used to measure the slave's speed.
+-
+-
    Smaller values of t increase communication, but improve load
+-balancing.  The default is 30 seconds.
+-
+-
    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER,
+-and PARALLEL_PERFECT.  PARALLEL_CHUNK_TAPER is usually best.
+-
+-
    PARALLEL_CHUNK_TAPER
+-
+-
    When you specify this statement, the master distributes work like
+-with PARALLEL_TIME_CHUNKS, except that the master chooses the number
+-of seconds for the chunks.  It starts with a large number and, as it
+-gets closer to finishing the job, reduces it.  That way, it reduces
+-scheduling overhead when precise scheduling isn't helpful, but still
+-prevents a slave from finishing early after all the work has already
+-been handed out to the other slaves, and then sitting idle while
+-there's still work to do.
+-
+-
    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER,
+-and PARALLEL_PERFECT.  PARALLEL_CHUNK_TAPER is usually best.
+-
+-
+-
    PARALLEL_PERFECT
+-
+-
    If this statement is present, ppmtompeg schedules on the
+-assumption that each machine is about the same speed.  The master will
+-simply divide up the frames evenly between the slaves -- each
+-slave gets the same number of frames.  If some slaves are faster than
+-others, they will finish first and remain idle while the slower slaves
+-continue.  
+-
+-
    This has the advantage of minimal scheduling overhead.  Where slaves
+-have different speeds, though, it makes inefficient use of the fast
+-ones.  Where slaves are the same speed, it also has the disadvantage
+-that they all finish at the same time and feed their output to the
+-single Combine Server in a burst, which makes less efficient use of
+-the Combine Server and thus can increase the total elapsed time.
+-
+-
    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER,
+-and PARALLEL_PERFECT.  PARALLEL_CHUNK_TAPER is usually best.
+-
+-
    RSH remote_shell_command
+-
+-
    ppmtompeg executes the shell command
+-remote_shell_command to start a process on another machine.
+-The default command is rsh, and whatever command you specify
+-must have compatible semantics.  ssh is usually compatible.
+-The command ppmtompeg uses is one like this:
+-ssh remote.host.com -l username shellcommand.
+-
+-
    Be sure to set up .rhosts files or SSH key authorizations
+-where needed.  Otherwise, you'll have to type in passwords.
+-
+-
    On some HP machines, rsh is the restricted shell, and you want
+-to specify remsh.
+-
+-
    FORCE_I_ALIGN
+-
+-
    This statement forces each slave to encode a chunk of frames which
+-is a multiple of the pattern length (see PATTERN).  Since the
+-first frame in any pattern is an I frame, this forces each chunk
+-encoded by a slave to begin with an I frame.
+-
+-
    This document used to say there was an argument to
+-FORCE_I_ALIGN which was the number of frames ppmtompeg
+-would use (and was required to be a multiple of the pattern length).
+-But ppmtompeg has apparently always ignored that argument, and
+-it does now.
+-
+-
    KEEP_TEMP_FILES
+-
+-
    This statement causes ppmtompeg not to delete the temporary
+-files it uses to transmit encoded frames to the combine server.  This
+-means you will be left with a file for each frame, the same as you
+-would get with the -frames option.  
+-
+-
    This is mostly useful for debugging.
+-
+-
    This works only if you're using a shared filesystem to communicate
+-between the servers.
+-
+-
    This option was new in Netpbm 10.26 (January 2005).
+-
+-
    
+-
+-
+-
    Parameter File Notes
    
+-
+-
     If you use the -combine_gops option, then you need to specify
+-only the SIZE and OUTPUT values in the parameter file.  In
+-addition, the parameter file may specify input GOP files in the same
+-manner as normal input files -- except instead of using INPUT_DIR,
+-INPUT, and END_INPUT, use GOP_INPUT_DIR, GOP_INPUT, and GOP_END_INPUT.
+-If you specify no input GOP files, then ppmtompeg uses by default the
+-output file name with suffix .gop.gop_num, with gop_num
+-starting from 0, as the input files. 
+-
+-
    If you use the -combine_frames option, then you need to
+-specify only the SIZE, GOP_SIZE, and OUTPUT values in the
+-parameter file.  In addition, the parameter file may specify input
+-frame files in the same manner as normal input files -- except instead
+-of using INPUT_DIR, INPUT, and END_INPUT, use FRAME_INPUT_DIR,
+-FRAME_INPUT, and FRAME_END_INPUT.  If no input frame files are
+-specified, then the default is to use the output file name with suffix
+-.frame.frame_num, with frame_num starting from 0,
+-as the input files.
+-
+-
    Any number of spaces and tabs may come between each option and value.  Lines
+-beginning with # are ignored.  Any other lines are ignored except for
+-those between INPUT and END_INPUT.  This allows you to use the same
+-parameter file for normal usage and for -combine_gops and
+--combine_frames.
+-
+-
    The file format is case-sensitive so all keywords should be in
+-upper case.
+-
+-
    The statements may appear in any order, except that the order within
+-a block statement (such as INPUT ... END INPUT) is significant.
+-
+-
    ppmtompeg is prepared to handle up to 16 B frames between
+-reference frames when encoding with input from stdin.  (To build a
+-modified ppmtompeg with a higher limit, change the constant
+-B_FRAME_RUN in frame.c and recompile).
+-
+-
    GENERAL USAGE INFORMATION
    
+-
+-
    Qscale
    
+-
+-
    The quantization scale values (qscale) give a trade-off between
+-quality and compression.  Using different Qscale values has very little
+-effect on speed.  The qscale values can be set separately for I, P, and
+-B frames.
+-
+-
    You select the qscale values with the IQSCALE,
+-PQSCALE, and BSCALE parameter file statements.
+-
+-
    A qscale value is an integer from 1 to 31.  Larger numbers give
+-better compression, but worse quality.  In the following, the quality
+-numbers are peak signal-to-noise ratio, defined as:
+-signal-to-noise formula
+-where MSE is the mean squared error.

    Search Techniques
    
+-     
+-
    There are several different motion vector search techniques
+-available.  There are different techniques available for P frame
+-search and B frame search. Using different search techniques present
+-little difference in quality, but a large difference in compression
+-and speed.
+-     
+-
    There are 4 types of P frame search: Exhaustive, TwoLevel,
+-SubSample, and Logarithmic.
+-     
+-
    There are 3 types of B frame search: Exhaustive, Cross2, and
+-Simple.
+-     
+-The recommended search techniques are TwoLevel and Logarithmic for
+-P frame search, and Cross2 and Simple for B frame search. Here are
+-some numbers comparing the different search methods:

+-
+-
+-
    Group Of Pictures (GOP)
    
+-
+-
    A Group of Pictures (GOP) is a roughly independently decodable
+-sequence of frames.  An MPEG video stream is made of one or more
+-GOP's.  You may specify how many frames should be in each GOP with the
+-GOP_SIZE parameter file statement.  A GOP always starts with an
+-I frame.
+-
+-
    Instead of encoding an entire sequence, you can encode a single
+-GOP.  To do this, use the -gop command option.  You can later
+-join the resulting GOP files at any time by running ppmtompeg
+-with the -combine_gops command option.
+-     
+-     
+-
    Slices
    
+-
+-
    A slice is an independently decodable unit in a frame.  It can be
+-as small as one macroblock, or it can be as big as the entire frame.
+-Barring transmission error, adding slices does not change quality or
+-speed; the only effect is slightly worse compression.  More slices are
+-used for noisy transmission so that errors are more recoverable. Since
+-usually errors are not such a problem, we usually just use one slice
+-per frame.
+-     
+-
    Control the slice size with the SLICES_PER_FRAME parameter
+-file statement.
+-
+-
    Some MPEG playback systems require that each slice consist of whole
+-rows of macroblocks.  If you are encoding for this kind of player, if
+-the height of the image is H pixels, then you should set the
+-SLICES_PER_FRAME to some number which divides H/16.  For example, if
+-the image is 240 pixels (15 macroblocks) high, then you should use
+-only 15, 5, 3, or 1 slices per frame.
+-     
+-
    Note: these MPEG playback systems are really wrong, since the MPEG
+-standard says this doesn't have to be so.
+-
+-
+-
+-
    Search Window
    
+-     
+-
    The search window is the window in which ppmtompeg searches
+-for motion vectors.  The window is a square.  You can specify the size
+-of the square, and whether to allow half-pixel motion vectors or not,
+-with the RANGE and PIXEL parameter file statements.
+-
+-
    I Frames, P Frames, B Frames
    
+-
+-
    In MPEG-1, a movie is represented as a sequence of MPEG frames,
+-each of which is an I Frame, a P Frame, or a B Frame.  Each represents
+-an actual frame of the movie (don't get confused by the dual use of
+-the word "frame."  A movie frame is a graphical image.  An MPEG frame
+-is a set of data that describes a movie frame).
+-
+-
    An I frame ("intra" frame) describes a movie frame in isolation --
+-without respect to any other frame in the movie.  A P frame
+-("predictive" frame) describes a movie frame by describing how it
+-differs from the movie frame described by the latest preceding I  or
+-P frame.  A B frame ("bidirectional" frame) describes a movie frame by
+-describing how it differs from the movie frames described by the
+-nearest I or P frame before and after it.
+-
+-
    Note that the first frame of a movie must be described by an I
+-frame (because there is no previous movie frame) and the last movie
+-frame must be described by an I or P frame (because there is no
+-subsequent movie frame).
+-
+-
    Beyond that, you can choose which frames are represented by which
+-types.  You specify a pattern, such as IBPBP and ppmtompeg
+-simply repeats it over and over throughout the movie.  The pattern
+-affects speed, quality, and stream size.  Here is a chart which shows
+-some of the trade-offs:

+-     
+-
    Select the sequence with the PATTERN parameter file statement.
+-
+-
    Since the last MPEG frame cannot be a B frame (see above), if the
+-pattern you specify indicates a B frame for the last movie frame of
+-the movie, ppmtompeg makes it an I frame instead.
+-
+-
    Before Netpbm 10.26 (January 2005), ppmtompeg instead drops
+-the trailing B frames by default, and you need the
+-FORCE_ENCODE_LAST_FRAME parameter file statement to make it do
+-this.
+-
+-
    The MPEG frames don't appear in the MPEG-1 stream in the same order that
+-the corresponding movie frames appear in the movie -- the B frames come after
+-the I and P frames on which they are based.  For example, if the movie is
+-4 frames that you will represent with the pattern IBBP, the MPEG-1 stream
+-will start with an I frame describing movie frame 0.  The next frame in
+-the MPEG-1 stream is a P frame describing movie frame 3.  The last two
+-frames in the MPEG-1 stream are B frames describing movie frames 1 and 2,
+-respectively.
+-
+-
+-
    Specifying Input and Output Files
     
+-
+-
    Specify the input frame images with the INPUT_DIR,
+-INPUT, END_INPUT, BASE_FILE_FORMAT,
+-SIZE, YUV_FORMAT and INPUT_CONVERT parameter
+-file statements.
+-
+-
    Specify the output file with the OUTPUT parameter file statement.
+-
+-
+-
    Statistics
    
+-
+-
    ppmtompeg can generate a variety of statistics about the 
+-encoding.  See the -stat, -snr, -mv_histogram,
+--quiet, -no_frame_summary, and -bit_rate_info
+-options.
+-     
+-
+-
    PARALLEL OPERATION
    
+-
+-
    You can run ppmtompeg on multiple machines at once, encoding
+-the same MPEG stream.  When you do, the machines are used as shown in
+-the following diagram.  We call this "parallel mode."
+-
+-
    ppmtompeg-par.gif
+-
+-
    To do parallel processing, put the statement
+-
+-
    +-    PARALLEL
+-
    
+-
+-in the parameter file, followed by a listing of the machines, one
+-machine per line, then
+-
+-
    +-    END_PARALLEL
+-
    
+-
+-Each of the machine lines must be in one of two forms.  If the machine
+-has filesystem access to the input files, then the line is:
+-
+-
    
+-machine user executable
+-
+-
    The executable is normally ppmtompeg (you may need to give
+-the complete path if you've built for different architectures).  If
+-the machine does not have filesystem access to the input files, the line
+-is:
+-
+-
    REMOTE machine user executable
+-parameter file
+-
+-
    The -max_machines command option limits the number of
+-machines ppmtompeg will use.  If you specify more machines in
+-the parameter file than -max_machines allows, ppmtompeg
+-uses only the machines listed first.  This is handy if you want to
+-experiment with different amounts of parallelism.
+-
+-
    In general, you should use full path file names when describing
+-executables and parameter files.  This includes the parameter
+-file argument on the original invocation of ppmtompeg.
+-
+-
    All file names must be the same on all systems (so if e.g. you're
+-using an NFS filesystem, you must make sure it is mounted at the same
+-mountpoint on all systems).
+-
+-
    Because not all of the processes involved in parallel operation
+-have easy access to the input files, you must specify the SIZE
+-parameter file statement when you do parallel operation.
+-
+-
    The machine on which you originally invoke ppmtompeg is the
+-master machine.  It hosts a "combine server,", a
+-"decode server," and a number of "i/o servers,"
+-all as separate processes.  The other machines in the network (listed
+-in the parameter file) are slave machines.  Each hosts a single
+-process that continuously requests work from the master and does it.
+-The slave process does the computation to encode MPEG frames.  It
+-processes frames in batches identified by the master.
+-
+-
    The master uses a remote shell command to start a process on a
+-slave machine.  By default, it uses an rsh shell command to do
+-this.  But use the RSH parameter file statement to control
+-this.  The shell command the master executes remotely is
+-ppmtompeg, but with options to indicate that it is to perform
+-slave functions.
+-
+-
    The various machines talk to each other over TCP connections.  Each
+-machine finds and binds to a free TCP port number and tells its
+-partners the port number.  These port numbers are at least 2048.
+-
+-
    Use the PARALLEL_TEST_FRAMES, PARALLEL_TIME_CHUNKS, and
+-PARALLEL_PERFECT parameter file statements to control the way the
+-master divides up work among the slaves.
+-
+-
    Use the -nice command option to cause all slave processes to run
+-"nicely," i.e. as low priority processes.  That way, this substantial and
+-long-running CPU load will have minimal impact on other, possibly
+-interactive, users of the systems.
+-
+-
    SPEED

    Here is a look at ppmtompeg speed, in single-node (not parallel)
+-operation:

    The measurements in the table are with inputs and outputs via a
+-conventional locally attached filesystem.  If you are using a network
+-filesystem over a single 10 MB/s Ethernet, that constrains your speed more
+-than your CPU speed.  In that case, don't expect to get better than 4
+-or 5 frames per second no matter how fast your CPUs are.
+-
+-
    Network speed is even more of a bottleneck when the slaves do not
+-have filesystem access to the input files -- i.e. you declare them
+-REMOTE.
+-
+-
    Where I/O is the bottleneck, size of the input frames can make a big
+-difference.  So YUV input is better than PPM, and JPEG is better than
+-both.
+-
+-
    When you're first trying to get parallel mode working, be sure to
+-use the -debug_machines option so you can see what's going on.
+-Also, -debug_sockets can help you diagnose communication
+-problems.

-+.SH DESCRIPTION
-+.PP
-+This program is part
-+of 
-+.UR http://netpbm.sourceforge.net/
-+Netpbm
-+.UE
-+\&.
-+.PP
-+\fBpamhomography\fP transforms a quadrilateral-not necessarily
-+rectangular-region of an image, producing a new image.
-+.PP
-+You can do any
-+.UR https://en.wikipedia.org/wiki/Affine_transformation#Image_transformation
-+affine image transformation
-+.UE
-+\&: translation, reflection, scaling,
-+rotation, and shearing/skewing. However, \fBpamhomography\fP additionally can
-+do \fIbilinear\fP transforms, which means it can warp any quadrilateral to any
-+other quadrilateral, even when this mapping cannot be described using a single
-+set of linear equations. This can be useful, for example, for creating
-+perspective views of rectangular images or for reverse-mapping a perspective
-+view back to a rectangular projection.
-+
-+
-+.UN OPTIONS
-+.SH OPTIONS
-+.PP
-+In addition to the options common to all programs based on libnetpbm (most
-+notably \fB-quiet\fP, see 
-+.UR http://index.html#commonoptions
-+Common Options
-+.UE
-+\&), \fBpamhomography\fP recognizes the following command line
-+options:
-+
-+
-+
-+
    \fB-from\fP=\fIcoords\fP
-+.sp
-+This defines the source quadrilateral. \fIcoords\fP is a list of four
-+  integer-valued (\fIx\fP, \fIy\fP) coordinates. If you do not
-+  specify \fB-from\fP, the source quadrilateral is taken to be the four
-+  corners of the input image in clockwise order, starting from the upper
-+  left.
-+
-+
-+
    \fB-to\fP=\fIcoords\fP
-+.sp
-+This defines the target quadrilateral. \fIcoords\fP is a list of four
-+integer-valued (\fIx\fP, \fIy\fP) coordinates. If you do not
-+specify \fB-to\fP, the target quadrilateral is taken to be the four corners
-+of the input image in clockwise order, starting from the upper left.
-+
-+
-+
    \fB-mapfile\fP=\fImap_file\fP
-+.sp
-+This names a text file that describes the mapping from the source to the
-+target quadrilateral. The file \fImap_file\fP must contain either eight
-+integer-valued (\fIx\fP, \fIy\fP) coordinates, being the four source
-+coordinates followed by the corresponding four target coordinates, or only
-+four (\fIx\fP, \fIy\fP) coordinates, being only the four target
-+coordinates. In the latter case, the source quadrilateral is taken to be the
-+four corners of the input image in clockwise order, starting from the upper
-+left.
-+
-+
-+
    \fB-view\fP=\fIcoords\fP
-+.sp
-+This defines the target view. \fIcoords\fP is a list of two integer-valued
-+(\fIx\fP, \fIy\fP) coordinates: the upper left and lower right boundaries,
-+respectively, of the pixels that will be visible in the output image. If
-+\fB-view\fP is not specified, the target view will fit precisely the target
-+quadrilateral.
-+
-+
-+
    \fB-fill\fP=\fIcolor\fP
-+.sp
-+This is the color with which the program fills all pixels that lie outside
-+of the target quadrilateral. Specify the color as described for the
-+.UR http://libnetpbm_image.html#colorname
-+ argument of the pnm_parsecolor() library routine
-+.UE
-+\&.
-+.sp
-+The default is black, and for images with a transparency plane, transparent.
-+
-+
-+
-+.PP
-+Cooordinates should normally be specified in clockwise order. The syntax is
-+fairly flexible: all characters other than the plus sign, minus sign, and
-+digits are treated as separators. Although coordinates need to be integers,
-+they may lie outside the image's boundary.
-+.PP
-+If you specify \fB-mapfile\fP along with \fB-from\fP and/or \fB-to\fP,
-+\fB-from\fP and \fB-to\fP override the quadrilaterals specified
-+by \fImap_file\fP.
-+
-+
-+.UN PARAMETERS
-+.SH PARAMETERS
-+.PP
-+\fBpamhomography\fP's only parameter, \fIpam_file\fP, is the name of the
-+  file containing the input image. If you don't specify \fIpam_file\fP, the
-+  image comes from Standard Input.
-+
-+  
-+.UN NOTES
-+.SH NOTES
-+.PP
-+The output image uses the same Netpbm format as the input image.
-+.PP
-+Simple transformations are best handled by other Netpbm programs, such as
-+those listed in the 
-+.UR #SEE-ALSO
-+\&'SEE ALSO'
-+.UE
-+\& section
-+below. Use \fBpamhomography\fP for more sophisticated transformations such as
-+perspective adjustments, rotations around an arbitrary point in the image,
-+extraction of non-rectangular quadrilaterals, shearings by coordinates rather
-+than by angle, and, in general, all transformations that are most easily
-+expressed as mapping four points in one image to four points in another
-+image.
-+
-+.UN EXAMPLES
-+.SH EXAMPLES
-+.PP
-+The following examples use the
-+.UR park_row.ppm
-+park_row.ppm 
-+.UE
-+\& test image, which is a
-+.UR https://commons.wikimedia.org/wiki/File:15_Park_Row_3.JPG
-+ photograph of New York City's Park Row Building
-+.UE
-+\&, scaled to
-+441×640, converted to a PPM file, and redistributed under the terms of
-+the 
-+.UR https://en.wikipedia.org/wiki/GNU_Free_Documentation_License
-+ GFDL
-+.UE
-+\&.
-+.PP
-+The first example showcases the real power of bilinear transformations.
-+Assuming \fIpark_row_rect.map\fP has the following contents:
-+
-+.nf\f(CW    (147, 51) (316, 105) (402, 595) (92, 560)
-+      (0,  0) (440,   0) (440, 639)  (0, 639)\fP
    -+.PP -+then -+ -+.nf\f(CW pamhomography -mapfile park_row_rect.map park_row.ppm > park_row_rect.ppm\fP -+.PP -+projects the building's facade from a perspective view to a rectilinear -+front-on view. Remember that \fBpamhomography\fP ignores the parentheses and -+commas used in \fIpark_row_rect.map\fP; they merely make the file more -+human-readable. We equivalently could have written -+ -+.nf\f(CW 147 51 316 105 402 595 92 560 0 0 440 0 440 639 0 639\fP -+.PP -+or any of myriad other variations. -+.PP -+\fBpamhomography\fP can warp the image to a trapezoid to make it look like -+it's leaning backwards in 3-D: -+ -+.nf\f(CW pamhomography -to '50,0 390,0 440,200 0,200' park_row.ppm > park_row_trap.ppm\fP -+.PP -+As a very simple example, -+ -+.nf\f(CW pamhomography -to '440,0 0,0 0,639 440,639' park_row.ppm > park_row_flip.ppm\fP -+.PP -+flips the image left-to-right. Note that in this case the target -+quadrilateral's coordinates are listed in counterclockwise order because -+that represents the correspondence between points (0, 0) ↔ (440, 0) and -+(0, 639) ↔ (639, 0). -+.PP -+Scaling is also straightforward. The following command scales down the -+image from 441×640 to 341×540: -+ -+.nf\f(CW pamhomography -to '0,0 340,0 340,539 0,539' park_row.ppm > park_row_small.ppm\fP -+.PP -+Let's add 100 pixels of tan border to the above.

    NAME

    --ppmtompeg - encode an MPEG-1 bitstream -- --

    SYNOPSIS

    -- --ppmtompeg --[options] --parameter-file -- --

    DESCRIPTION

    -- --

    This program is part of Netpbm. -- --

    ppmtompeg produces an MPEG-1 video stream. MPEG-1 is the --first great video compression method, and is what is used in Video CDs --(VCD). ppmtompeg originated in the year 1995. DVD uses a more --advanced method, MPEG-2. There is an even newer method called MPEG-4 --which is also called Divx. I don't know where one finds that used. -- --

    There's technically a difference between a compression method for --video and an actual file (stream) format for a movie, and I don't know --if it can be validly said that the format of the stream --ppmtompeg produces is MPEG-1. -- --

    Mencoder from the Mplayer --package is probably superior for most video format generation --needs, if for no other reason than that it is more popular. -- --

    The programming library PM2V --generates MPEG-2 streams. -- --

    Use Mplayer (not part of Netpbm) --to do the reverse conversion: to create a series of PNM files from an MPEG --stream. -- --

    param_file is a parameter file which includes a list of --input files and other parameters. The file is described in detail --below. -- --

    To understand this program, you need to understand something about --the complex MPEG-1 format. One source of information about this --standard format is the section Introduction to MPEG in the Compression FAQ. -- --

    OPTIONS

    -- --

    The -gop, -combine_gops, -frames, and ---combine_frames options are all mutually exclusive. -- --

    --
    -stat stat_file -- --
    This option causes ppmtompeg to append the statistics that --it write to Standard Output to the file stat_file as well. The --statistics use the following abbreviations: bits per block (bpb), bits --per frame (bpf), seconds per frame (spf), and bits per second (bps). -- --

    These statistics include how many I, P, and B frames there were, --and information about compression and quality. -- -- --

    -quiet num_seconds -- --
    causes ppmtompeg not to report remaining time more often --than every num_seconds seconds (unless the time estimate rises, --which will happen near the beginning of the run). A negative value --tells ppmtompeg not to report at all. 0 is the default --(reports once after each frame). Note that the time remaining is an --estimate and does not take into account time to read in frames. -- --
    -realquiet
    causes ppmtompeg to run silently, --with the only screen output being errors. Particularly useful when --reading input from stdin. The equivalent of the -quiet --common option of most other Netpbm programs. -- --
    ---no_frame_summary -- --
    This option prevents ppmtompeg from printing a summary --line for each frame -- --
    -float_dct -- --
    forces ppmtompeg to use a more accurate, yet more --computationally expensive version of the DCT. -- --
    -gop gop_num --
    --causes ppmtompeg to encode only the numbered GOP (first GOP is 0). The --parameter file is the same as for normal usage. The output file will be --the normal output file with the suffix .gop.gop_num. --ppmtompeg does not output any sequence information. -- --
    -combine_gops -- --
    causes ppmtompeg simply to combine some GOP files into a --single MPEG output stream. ppmtompeg inserts a sequence header --and trailer. In this case, the parameter file needs only to contain --the SIZE value, an output file, and perhaps a list of input GOP --files (see below). -- --If you don't supply a list of input GOP files is used, then --ppmtompeg assumes you're using the same parameter file you used --when you created the input (with the -gop option) and --calculates the corresponding gop filenames itself. If this is not the --case, you can specify input GOP files in the same manner as normal --input files -- except instead of using INPUT_DIR, INPUT, and --END_INPUT, use GOP_INPUT_DIR, GOP_INPUT, and GOP_END_INPUT. If no --input GOP files are specified, then the default is to use the output --file name with suffix .gop.gop_num, with gop_num --starting from 0, as the input files. -- --

    Thus, unless you're mixing and matching GOP files from different --sources, you can simply use the same parameter file for creating the --GOP files (-gop) and for later turning them into an MPEG stream --(-combine_gops). -- -- --

    -frames first_frame last_frame -- --
    This option causes ppmtompeg to encode only the frames numbered --first_frame to last_frame, inclusive. The parameter --file is the same as for normal usage. The output will be placed in --separate files, one per frame, with the file names being the normal --output file name with the suffix .frame.frame_num. No --GOP header information is output. (Thus, the parameter file need not --include the GOP_SIZE value) -- --

    Use ppmtompeg -combine_frames to combine these frames later into --an MPEG stream. -- -- --

    -combine_frames -- --
    This option causes ppmtompeg simply to combine some --individual MPEG frames (such as you might have created with an earlier --run of ppmtompeg -frames) into a single MPEG stream. Sequence --and GOP headers are inserted appropriately. In this case, the --parameter file needs to contain only the SIZE value, the GOP_SIZE --value, an output file, and perhaps a list of frame files (see below). -- --

    The parameter file may specify input frame files in the same manner --as normal input files -- except instead of using INPUT_DIR, INPUT, and --END_INPUT, use FRAME_INPUT_DIR, FRAME_INPUT, and FRAME_END_INPUT. If --no input frame files are specified, then the default is to use the --output file name with suffix .frame.frame_num, with --frame_num starting from 0, as the input files. -- -- -- --

    -nice -- --
    This option causes ppmtompeg to run any remote processes --"nicely," i.e. at low priority. (This is relevant only if you are --running ppmtompeg in parallel mode. Otherwise, there are no --remote processes). See 'man nice.' -- --
    -max_machines num_machines -- --
    This option causes ppmtompeg to use no more than --num_machines machines as slaves for use in parallel encoding. -- --
    -snr -- --
    This option causes ppmtompeg to include the signal-to-noise --ratio in the reported statistics. Prints SNR (Y U V) and peak SNR (Y --U V) for each frame. In summary, prints averages of luminance only --(Y). SNR is defined as 10*log(variance of original/variance of --error). Peak SNR is defined as 20*log(255/RMSE). Note that --ppmtompeg runs a little slower when you use this option. -- --
    -mse -- --
    This option causes ppmtompeg to report the mean squared --error per block. It also automatically reports the quality of the --images, so there is no need to specify -snr then. -- --
    -bit_rate_info rate_file -- --
    This option makes ppmtompeg write bit rate information --into the file rate_file. Bit rate information is bits per frame, and --also bits per I-frame-to-I-frame. -- --
    -mv_histogram -- --
    This option causes ppmtompeg to print a histogram of the --motion vectors as part of statistics. There are three histograms -- --one for P frame, one for forward B frame, and one for backward B frame --motion vectors. -- --

    The output is in the form of a matrix, each entry corresponding to one --motion vector in the search window. The center of the matrix --represents (0,0) motion vectors. -- --

    -debug_sockets -- --
    This option causes ppmtompeg to print to Standard Output --messages that narrate the communication between the machines when you run --ppmtompeg in parallel mode. -- --
    -debug_machines -- --
    This option causes ppmtompeg to print to Standard Output --messages that narrate the progress of the conversion on the various --machines when you run ppmtompeg in parallel --mode. -- --
    -- --

    PARAMETER FILE

    -- --

    The parameter file must contain the following --lines (except when using the -combine_gops or -combine_frames --options): -- --

    -- --
    PATTERN pattern -- --
    This statement specifies the pattern (sequence) of I frames, P frames, --and B frames. pattern is just a sequence of the letters I, P, and --B with nothing between. Example: -- --
    --    PATTERN IBBPBBPBBPBBPBB
--
    -- --

    See I Frames, P Frames, B Frames. -- --

    OUTPUT output file --
    This names the file where the output MPEG stream goes. -- --
    INPUT_DIR directory -- --
    This statement tells where the input images (frames) come from. --If each frame is in a separate file, directory is the directory --where they all are. You may use . to refer to the current --directory. A null directory refers to the root directory of the --system file tree. -- --

    To have ppmtompeg read all the frames serially from Standard --Input, specify --

    --    INPUT_DIR stdin
--
    -- --
    INPUT --
    --This line must be followed by a list of the input files (in display order) --and then the line END_INPUT. -- --

    There are three types of lines between INPUT and END_INPUT. First, --a line may simply be the name of an input file. Second, the line --may be of the form single_star_expr --[x-y]. --single_star_expr can have a single * in it. It is --replaced by all the numbers between x and y inclusive. So, for --example, the line tennis*.ppm [12-15] refers to the files --tennis12.ppm, tennis13.ppm, tennis14.ppm, tennis15.ppm. -- --

    Uniform zero-padding occurs, as well. For example, the line --football.*.ppm [001-130] refers to the files football.001.ppm, --football.002.ppm, ..., football.009.ppm, football.010.ppm, ..., --football.130.ppm. -- --

    The third type of line is: single_star_expr --[x-y+s], where the --line is treated exactly as above, except that we skip by s. Thus, the --line football.*.ppm [001-130+4] refers to the files --football.001.ppm, football.005.ppm, football.009.ppm, --football.013.ppm, etc. -- --

    Furthermore, a line may specify a shell command to execute to --generate lines to be interpreted as described above, as if those lines --were in the parameter file instead. Use back ticks, like in the --Bourne Shell, like this: -- --

    --    `cat myfilelist`
--
    -- --

    --If input is from Standard Input (per the INPUT_DIR statement), --ppmtompeg ignores the INPUT/END_INPUT block, but --it still must be present. -- --

    BASE_FILE_FORMAT {PPM | PNM | YUV | -- JPEG | JMOVIE} -- --
    ppmtompeg must convert all input files to one of the --following formats as a first step of processing: PNM, YUV, JPEG(v4), --or JMOVIE. (The conversion may be trivial if your input files are --already in one of these formats). This line specifies which of the --four formats. PPM is actually a subset of PNM. The separate --specification is allowed for backward compatibility. Use PNM instead --of PPM in new applications. -- --
    INPUT_CONVERT conversion_command -- --
    You must specify how to convert a file to the base file format. --If no conversion is necessary, then you would just say: -- -- 
    --     INPUT_CONVERT *
--
    -- --

    Otherwise, conversion_command is a shell command that causes --an image in the format your specified with BASE_FILE_FORMAT to --be written to Standard Output. ppmtompeg executes the command --once for each line between INPUT and END_INPUT (which is --normally, but not necessarily, a file name). In the conversion --command, ppmtompeg replaces each '*' with the contents of that --line. -- -- If you had a bunch of gif files, you might say: -- 

    --     INPUT_CONVERT giftopnm *
--
    -- -- If you have a bunch of separate a.Y, a.U, and a.V files (where -- the U and V have already been subsampled), then you might say: -- -- 
    --     INPUT_CONVERT cat *.Y *.U *.V
--
    -- --

    Input conversion is not allowed with input from stdin, so use -- -- 

    --     INPUT_CONVERT *
--
    -- --as described above. -- --
    SIZE widthxheight -- --
    -- --

    width and height are the width and height of each --frame in pixels. -- --

    When ppmtompeg can get this information from the input image --files, it ignores the SIZE parameter and you may omit it. -- --

    When the image files are in YUV format, the files don't contain --dimension information, so SIZE is required. -- --

    When ppmtompeg is running in parallel mode, not all of the --processes in the network have access to the image files, so --SIZE is required and must give the same dimensions as the --input image files. -- --

    YUV_SIZE widthxheight -- --
    This is an obsolete synonym of SIZE. -- --
    YUV_FORMAT {ABEKAS | PHILLIPS | UCB | -- EYUV | pattern} -- --
    This is meaningful only when BASE_FILE_FORMAT specifies --YUV format, and then it is required. It specifies the sub-format of --the YUV class. -- -- --
    GOP_SIZE n -- --
    n is the number of frames in a Group of Pictures. Except that --because a GOP must start with an I frame, ppmtompeg makes a GOP as --much longer than n as it has to to make the next GOP start with an --I frame. -- --

    Normally, it makes sense to make your GOP size a multiple of your --pattern length (the latter is determined by the PATTERN parameter file --statement). -- --

    See Group Of Pictures. -- --

    SLICES_PER_FRAME n --
    n is roughly the number of slices per frame. Note, at --least one MPEG player may complain if slices do not start at the left --side of an image. To ensure this does not happen, make sure the --number of rows is divisible by SLICES_PER_FRAME. -- --
    PIXEL {FULL | HALF} -- --
    use half-pixel motion vectors, or just full-pixel ones It is --usually important that you use half-pixel motion vectors, because it --results in both better quality and better compression. -- -- --
    RANGE n --
    Use a search range of n pixels in each of the four directions --from a subject pixel. (So the search window is a square n*2 pixels --on a side). -- --
    PSEARCH_ALG {EXHAUSTIVE | TWOLEVEL | -- SUBSAMPLE | LOGARITHMIC} -- --
    This statement tells ppmtompeg what kind of search -- technique (algorithm) to use for P frames. You select the desired -- combination of speed and compression. EXHAUSTIVE gives the -- best compression, but LOGARITHMIC is the fastest. -- TWOLEVEL is an exhaustive full-pixel search, followed by a -- local half- pixel search around the best full-pixel vector (the -- PIXEL option is ignored for this search technique). -- --
    BSEARCH_ALG {SIMPLE | CROSS2 | EXHAUSTIVE} -- --
    This statement tells ppmtompeg what kind of search -- technique (algorithm) to use for B frames. SIMPLE means -- find best forward and backward vectors, then interpolate. -- CROSS2 means find those two vectors, then see what backward -- vector best matches the best forward vector, and vice versa. -- EXHAUSTIVE does an n-squared search and is -- extremely slow in relation to the others (CROSS2 -- is about half as fast as SIMPLE). -- --
    IQSCALE n --
    Use n as the qscale for I frames. -- See Qscale. -- --
    PQSCALE n --
    Use n as the qscale for P frames. -- See Qscale. -- --
    BQSCALE n --
    Use n as the qscale for B frames. -- See Qscale. -- --
    REFERENCE_FRAME {ORIGINAL | DECODED}
    This --statement determines whether ppmtompeg uses the original images --or the decoded images when computing motion vectors. Using decoded --images is more accurate and should increase the playback quality of --the output, but it makes the encoding take longer and seems to give --worse compression. It also causes some complications with parallel --encoding. (see the section on parallel encoding). One thing you can --do as a trade-off is select ORIGINAL here, and lower the --qscale (see QSCALE if the quality is not good enough. -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

    -- -- -- --
    -- --

    The following lines are optional: -- --

    -- --
    FORCE_ENCODE_LAST_FRAME -- --
    This statement is obsolete. It does nothing. -- --

    Before Netpbm 10.26 (January 2005), ppmtompeg would drop --trailing B frames from your movie, since a movie can't end with a B --frame. (See I Frames, P Frames, B Frames. --You would have to specify FORCE_ENCODE_LAST_FRAME to stop --that from happening and get the same function that ppmtompeg --has today. -- -- --

    NIQTABLE -- --
    This statement specifies a custom non-intra quantization table. --If you don't specify this statement, ppmtompeg uses a default --non-intra quantization table. -- --

    --The 8 lines immediately following NIQTABLE specify the quantization --table. Each line defines a table row and consists of 8 integers, --whitespace-delimited, which define the table columns. -- --

    IQTABLE -- --
    This is analogous to NIQTABLE, but for the intra quantization table. -- --
    ASPECT_RATIO ratio -- --
    This statement specifies the aspect ratio for ppmtompeg to --specify in the MPEG output. I'm not sure what this is used for. -- --

    ratio must be 1.0, 0.6735, 0.7031, 0.7615, 0.8055, 0.8437, --0.8935, 0.9157, 0.9815, 1.0255, 1.0695, 1.0950, 1.1575, or 1.2015. -- --

    FRAME_RATE rate --
    This specifies the frame rate for ppmtompeg to specify in the --MPEG output. Some players use this value to determine the playback rate. -- --

    rate must be 23.976, 24, 25, 29.97, 30, 50, 59.94, or 60. -- --

    BIT_RATE rate --
    This specifies the bit rate for Constant Bit Rate (CBR) encoding. -- --

    rate must be an integer. -- --

    BUFFER_SIZE size -- --
    This specifies the value --ppmtompeg is to specify in the MPEG output for the Video --Buffering Verifier (VBV) buffer size needed to decode the sequence. -- --

    A Video Verifying Buffer is a buffer in which a decoder keeps the --decoded bits in order to match the uneven speed of the decoding with --the required constant playback speed. -- --

    As ppmtompeg encodes the image, it simulates the decoding --process in terms of how many bits would be in the VBV as each frame gets --decoded, assuming a VBV of the size you indicate. -- --

    If you specify the WARN_VBV_UNDERFLOW statement, --ppmtompeg issues a warning each time the simulation underflows --the buffer, which suggests that an underflow would occur on playback, --which suggests the buffer is too small. -- --

    If you specify the WARN_VBV_OVERFLOW statement, --ppmtompeg issues a warning each time the simulation overflows --the buffer, which suggests that an overflow would occur on playback, --which suggests the buffer is too small. -- --

    WARN_VBV_UNDERFLOW --
    WARN_VBV_OVERFLOW -- --
    See BUFFER_SIZE. -- --

    These options were new in Netpbm 10.26 (January 2005). Before that, --ppmtompeg issued the warnings always. -- --

    -- -- --The following statements apply only to parallel operation: -- --
    -- --
    PARALLEL -- --
    This statement, paired with END PARALLEL, is what causes --ppmtompeg to operate in parallel mode. See Parallel Operation. -- --
    END PARALLEL -- --
    This goes with PARALLEL. -- --
    PARALLEL_TEST_FRAMES n -- --
    The master starts off by measuring each slave's speed. It does --this by giving each slave n frames to encode and noting how --long the slave takes to finish. These are not just test frames, --though -- they're real frames and the results become part of the --output. --ppmtompeg is old and measures time in undivided seconds, so --to get useful timings, specify enough frames that it will take at --least 5 seconds to process them. The default is 10. -- --

    If you specify FORCE_I_ALIGN, ppmtompeg will increase --the test frames value enough to maintain the alignment. -- --

    If there aren't enough frames for every slave to have the indicated --number of test frames, ppmtompeg will give some slaves fewer. -- -- --

    PARALLEL_TIME_CHUNKS t -- --
    When you specify this statement, the master attempts to feed work --to the slaves in chunks that take t seconds to process. It uses --the speed measurement it made when it started up (see PARALLEL_TEST_FRAMES) --to decide how many frames to put in the chunk. This statement obviously --doesn't affect the first batch of work sent to each slave, which is the --one used to measure the slave's speed. -- --

    Smaller values of t increase communication, but improve load --balancing. The default is 30 seconds. -- --

    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER, --and PARALLEL_PERFECT. PARALLEL_CHUNK_TAPER is usually best. -- --

    PARALLEL_CHUNK_TAPER -- --
    When you specify this statement, the master distributes work like --with PARALLEL_TIME_CHUNKS, except that the master chooses the number --of seconds for the chunks. It starts with a large number and, as it --gets closer to finishing the job, reduces it. That way, it reduces --scheduling overhead when precise scheduling isn't helpful, but still --prevents a slave from finishing early after all the work has already --been handed out to the other slaves, and then sitting idle while --there's still work to do. -- --

    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER, --and PARALLEL_PERFECT. PARALLEL_CHUNK_TAPER is usually best. -- -- --

    PARALLEL_PERFECT -- --
    If this statement is present, ppmtompeg schedules on the --assumption that each machine is about the same speed. The master will --simply divide up the frames evenly between the slaves -- each --slave gets the same number of frames. If some slaves are faster than --others, they will finish first and remain idle while the slower slaves --continue. -- --

    This has the advantage of minimal scheduling overhead. Where slaves --have different speeds, though, it makes inefficient use of the fast --ones. Where slaves are the same speed, it also has the disadvantage --that they all finish at the same time and feed their output to the --single Combine Server in a burst, which makes less efficient use of --the Combine Server and thus can increase the total elapsed time. -- --

    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER, --and PARALLEL_PERFECT. PARALLEL_CHUNK_TAPER is usually best. -- --

    RSH remote_shell_command -- --
    ppmtompeg executes the shell command --remote_shell_command to start a process on another machine. --The default command is rsh, and whatever command you specify --must have compatible semantics. ssh is usually compatible. --The command ppmtompeg uses is one like this: --ssh remote.host.com -l username shellcommand. -- --

    Be sure to set up .rhosts files or SSH key authorizations --where needed. Otherwise, you'll have to type in passwords. -- --

    On some HP machines, rsh is the restricted shell, and you want --to specify remsh. -- --

    FORCE_I_ALIGN -- --
    This statement forces each slave to encode a chunk of frames which --is a multiple of the pattern length (see PATTERN). Since the --first frame in any pattern is an I frame, this forces each chunk --encoded by a slave to begin with an I frame. -- --

    This document used to say there was an argument to --FORCE_I_ALIGN which was the number of frames ppmtompeg --would use (and was required to be a multiple of the pattern length). --But ppmtompeg has apparently always ignored that argument, and --it does now. -- --

    KEEP_TEMP_FILES -- --
    This statement causes ppmtompeg not to delete the temporary --files it uses to transmit encoded frames to the combine server. This --means you will be left with a file for each frame, the same as you --would get with the -frames option. -- --

    This is mostly useful for debugging. -- --

    This works only if you're using a shared filesystem to communicate --between the servers. -- --

    This option was new in Netpbm 10.26 (January 2005). -- --

    -- -- --

    Parameter File Notes

    -- --

    If you use the -combine_gops option, then you need to specify --only the SIZE and OUTPUT values in the parameter file. In --addition, the parameter file may specify input GOP files in the same --manner as normal input files -- except instead of using INPUT_DIR, --INPUT, and END_INPUT, use GOP_INPUT_DIR, GOP_INPUT, and GOP_END_INPUT. --If you specify no input GOP files, then ppmtompeg uses by default the --output file name with suffix .gop.gop_num, with gop_num --starting from 0, as the input files. -- --

    If you use the -combine_frames option, then you need to --specify only the SIZE, GOP_SIZE, and OUTPUT values in the --parameter file. In addition, the parameter file may specify input --frame files in the same manner as normal input files -- except instead --of using INPUT_DIR, INPUT, and END_INPUT, use FRAME_INPUT_DIR, --FRAME_INPUT, and FRAME_END_INPUT. If no input frame files are --specified, then the default is to use the output file name with suffix --.frame.frame_num, with frame_num starting from 0, --as the input files. -- --

    Any number of spaces and tabs may come between each option and value. Lines --beginning with # are ignored. Any other lines are ignored except for --those between INPUT and END_INPUT. This allows you to use the same --parameter file for normal usage and for -combine_gops and ---combine_frames. -- --

    The file format is case-sensitive so all keywords should be in --upper case. -- --

    The statements may appear in any order, except that the order within --a block statement (such as INPUT ... END INPUT) is significant. -- --

    ppmtompeg is prepared to handle up to 16 B frames between --reference frames when encoding with input from stdin. (To build a --modified ppmtompeg with a higher limit, change the constant --B_FRAME_RUN in frame.c and recompile). -- --

    GENERAL USAGE INFORMATION

    -- --

    Qscale

    -- --

    The quantization scale values (qscale) give a trade-off between --quality and compression. Using different Qscale values has very little --effect on speed. The qscale values can be set separately for I, P, and --B frames. -- --

    You select the qscale values with the IQSCALE, --PQSCALE, and BSCALE parameter file statements. -- --

    A qscale value is an integer from 1 to 31. Larger numbers give --better compression, but worse quality. In the following, the quality --numbers are peak signal-to-noise ratio, defined as: --signal-to-noise formula --where MSE is the mean squared error. -- -- --

    Search Techniques

    -- --

    There are several different motion vector search techniques --available. There are different techniques available for P frame --search and B frame search. Using different search techniques present --little difference in quality, but a large difference in compression --and speed. -- --

    There are 4 types of P frame search: Exhaustive, TwoLevel, --SubSample, and Logarithmic. -- --

    There are 3 types of B frame search: Exhaustive, Cross2, and --Simple. -- --The recommended search techniques are TwoLevel and Logarithmic for --P frame search, and Cross2 and Simple for B frame search. Here are --some numbers comparing the different search methods: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --

    A Group of Pictures (GOP) is a roughly independently decodable --sequence of frames. An MPEG video stream is made of one or more --GOP's. You may specify how many frames should be in each GOP with the --GOP_SIZE parameter file statement. A GOP always starts with an --I frame. -- --

    Instead of encoding an entire sequence, you can encode a single --GOP. To do this, use the -gop command option. You can later --join the resulting GOP files at any time by running ppmtompeg --with the -combine_gops command option. -- -- --

    Slices

    -- --

    A slice is an independently decodable unit in a frame. It can be --as small as one macroblock, or it can be as big as the entire frame. --Barring transmission error, adding slices does not change quality or --speed; the only effect is slightly worse compression. More slices are --used for noisy transmission so that errors are more recoverable. Since --usually errors are not such a problem, we usually just use one slice --per frame. -- --

    Control the slice size with the SLICES_PER_FRAME parameter --file statement. -- --

    Some MPEG playback systems require that each slice consist of whole --rows of macroblocks. If you are encoding for this kind of player, if --the height of the image is H pixels, then you should set the --SLICES_PER_FRAME to some number which divides H/16. For example, if --the image is 240 pixels (15 macroblocks) high, then you should use --only 15, 5, 3, or 1 slices per frame. -- --

    Note: these MPEG playback systems are really wrong, since the MPEG --standard says this doesn't have to be so. -- -- -- --

    Search Window

    -- --

    The search window is the window in which ppmtompeg searches --for motion vectors. The window is a square. You can specify the size --of the square, and whether to allow half-pixel motion vectors or not, --with the RANGE and PIXEL parameter file statements. -- --

    I Frames, P Frames, B Frames

    -- --

    In MPEG-1, a movie is represented as a sequence of MPEG frames, --each of which is an I Frame, a P Frame, or a B Frame. Each represents --an actual frame of the movie (don't get confused by the dual use of --the word "frame." A movie frame is a graphical image. An MPEG frame --is a set of data that describes a movie frame). -- --

    An I frame ("intra" frame) describes a movie frame in isolation -- --without respect to any other frame in the movie. A P frame --("predictive" frame) describes a movie frame by describing how it --differs from the movie frame described by the latest preceding I or --P frame. A B frame ("bidirectional" frame) describes a movie frame by --describing how it differs from the movie frames described by the --nearest I or P frame before and after it. -- --

    Note that the first frame of a movie must be described by an I --frame (because there is no previous movie frame) and the last movie --frame must be described by an I or P frame (because there is no --subsequent movie frame). -- --

    Beyond that, you can choose which frames are represented by which --types. You specify a pattern, such as IBPBP and ppmtompeg --simply repeats it over and over throughout the movie. The pattern --affects speed, quality, and stream size. Here is a chart which shows --some of the trade-offs: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    Comparison of I/P/B Frames (Normalized)
    Frame TypeSizeSpeedQuality
    I frames100010001000
    P frames409609969
    B frames72260919
    -- --(this is with constant qscale) -- --

    A standard sequence is IBBPBBPBBPBBPBB. -- --

    Select the sequence with the PATTERN parameter file statement. -- --

    Since the last MPEG frame cannot be a B frame (see above), if the --pattern you specify indicates a B frame for the last movie frame of --the movie, ppmtompeg makes it an I frame instead. -- --

    Before Netpbm 10.26 (January 2005), ppmtompeg instead drops --the trailing B frames by default, and you need the --FORCE_ENCODE_LAST_FRAME parameter file statement to make it do --this. -- --

    The MPEG frames don't appear in the MPEG-1 stream in the same order that --the corresponding movie frames appear in the movie -- the B frames come after --the I and P frames on which they are based. For example, if the movie is --4 frames that you will represent with the pattern IBBP, the MPEG-1 stream --will start with an I frame describing movie frame 0. The next frame in --the MPEG-1 stream is a P frame describing movie frame 3. The last two --frames in the MPEG-1 stream are B frames describing movie frames 1 and 2, --respectively. -- -- --

    Specifying Input and Output Files

    -- --

    Specify the input frame images with the INPUT_DIR, --INPUT, END_INPUT, BASE_FILE_FORMAT, --SIZE, YUV_FORMAT and INPUT_CONVERT parameter --file statements. -- --

    Specify the output file with the OUTPUT parameter file statement. -- -- --

    Statistics

    -- --

    ppmtompeg can generate a variety of statistics about the --encoding. See the -stat, -snr, -mv_histogram, ---quiet, -no_frame_summary, and -bit_rate_info --options. -- -- --

    PARALLEL OPERATION

    -- --

    You can run ppmtompeg on multiple machines at once, encoding --the same MPEG stream. When you do, the machines are used as shown in --the following diagram. We call this "parallel mode." -- --

    ppmtompeg-par.gif -- --

    To do parallel processing, put the statement -- --

    --    PARALLEL
--
    -- --in the parameter file, followed by a listing of the machines, one --machine per line, then -- --
    --    END_PARALLEL
--
    -- --Each of the machine lines must be in one of two forms. If the machine --has filesystem access to the input files, then the line is: -- --

    --machine user executable -- --

    The executable is normally ppmtompeg (you may need to give --the complete path if you've built for different architectures). If --the machine does not have filesystem access to the input files, the line --is: -- --

    REMOTE machine user executable --parameter file -- --

    The -max_machines command option limits the number of --machines ppmtompeg will use. If you specify more machines in --the parameter file than -max_machines allows, ppmtompeg --uses only the machines listed first. This is handy if you want to --experiment with different amounts of parallelism. -- --

    In general, you should use full path file names when describing --executables and parameter files. This includes the parameter --file argument on the original invocation of ppmtompeg. -- --

    All file names must be the same on all systems (so if e.g. you're --using an NFS filesystem, you must make sure it is mounted at the same --mountpoint on all systems). -- --

    Because not all of the processes involved in parallel operation --have easy access to the input files, you must specify the SIZE --parameter file statement when you do parallel operation. -- --

    The machine on which you originally invoke ppmtompeg is the --master machine. It hosts a "combine server,", a --"decode server," and a number of "i/o servers," --all as separate processes. The other machines in the network (listed --in the parameter file) are slave machines. Each hosts a single --process that continuously requests work from the master and does it. --The slave process does the computation to encode MPEG frames. It --processes frames in batches identified by the master. -- --

    The master uses a remote shell command to start a process on a --slave machine. By default, it uses an rsh shell command to do --this. But use the RSH parameter file statement to control --this. The shell command the master executes remotely is --ppmtompeg, but with options to indicate that it is to perform --slave functions. -- --

    The various machines talk to each other over TCP connections. Each --machine finds and binds to a free TCP port number and tells its --partners the port number. These port numbers are at least 2048. -- --

    Use the PARALLEL_TEST_FRAMES, PARALLEL_TIME_CHUNKS, and --PARALLEL_PERFECT parameter file statements to control the way the --master divides up work among the slaves. -- --

    Use the -nice command option to cause all slave processes to run --"nicely," i.e. as low priority processes. That way, this substantial and --long-running CPU load will have minimal impact on other, possibly --interactive, users of the systems. -- --

    SPEED

    -- --

    Here is a look at ppmtompeg speed, in single-node (not parallel) --operation: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- --
    Compression Speed
    Machine TypeMacroblocks per second1
    HP 9000/755280
    DEC 3000/400247
    HP 9000/750191
    Sparc 10104
    DEC 500068
    --1A macroblock is a 16x16 pixel square -- --

    The measurements in the table are with inputs and outputs via a --conventional locally attached filesystem. If you are using a network --filesystem over a single 10 MB/s Ethernet, that constrains your speed more --than your CPU speed. In that case, don't expect to get better than 4 --or 5 frames per second no matter how fast your CPUs are. -- --

    Network speed is even more of a bottleneck when the slaves do not --have filesystem access to the input files -- i.e. you declare them --REMOTE. -- --

    Where I/O is the bottleneck, size of the input frames can make a big --difference. So YUV input is better than PPM, and JPEG is better than --both. -- --

    When you're first trying to get parallel mode working, be sure to --use the -debug_machines option so you can see what's going on. --Also, -debug_sockets can help you diagnose communication --problems. -- -- --

    NAME
    
--ppmtompeg - encode an MPEG-1 bitstream
--
--
    SYNOPSIS
    
--
--ppmtompeg
--[options]
--parameter-file
--
--
    DESCRIPTION
    
--
--
    This program is part of Netpbm.
--
--
    ppmtompeg produces an MPEG-1 video stream.  MPEG-1 is the
--first great video compression method, and is what is used in Video CDs
--(VCD).  ppmtompeg originated in the year 1995.  DVD uses a more
--advanced method, MPEG-2.  There is an even newer method called MPEG-4
--which is also called Divx.  I don't know where one finds that used.
--
--
    There's technically a difference between a compression method for
--video and an actual file (stream) format for a movie, and I don't know
--if it can be validly said that the format of the stream
--ppmtompeg produces is MPEG-1.
--
--
    Mencoder from the Mplayer
--package is probably superior for most video format generation
--needs, if for no other reason than that it is more popular.
--
--
    The programming library PM2V
--generates MPEG-2 streams.
--
--
    Use Mplayer (not part of Netpbm)
--to do the reverse conversion: to create a series of PNM files from an MPEG
--stream.
--
--
    param_file is a parameter file which includes a list of
--input files and other parameters.  The file is described in detail
--below.
--
--
    To understand this program, you need to understand something about
--the complex MPEG-1 format.  One source of information about this
--standard format is the section Introduction to MPEG in the Compression FAQ.
--
--
    OPTIONS
    
--
--
    The -gop, -combine_gops, -frames, and
---combine_frames options are all mutually exclusive.
--
--
    
--
    -stat stat_file
--
--
    This option causes ppmtompeg to append the statistics that
--it write to Standard Output to the file stat_file as well.  The
--statistics use the following abbreviations: bits per block (bpb), bits
--per frame (bpf), seconds per frame (spf), and bits per second (bps).
--
--
    These statistics include how many I, P, and B frames there were,
--and information about compression and quality.
--
--
--
    -quiet num_seconds
--
--
     causes ppmtompeg not to report remaining time more often
--than every num_seconds seconds (unless the time estimate rises,
--which will happen near the beginning of the run).  A negative value
--tells ppmtompeg not to report at all.  0 is the default
--(reports once after each frame).  Note that the time remaining is an
--estimate and does not take into account time to read in frames.
--
--
    -realquiet 
     causes ppmtompeg to run silently,
--with the only screen output being errors.  Particularly useful when
--reading input from stdin.  The equivalent of the -quiet
--common option of most other Netpbm programs.
--
--
    
---no_frame_summary
--
--
     This option prevents ppmtompeg from printing a summary
--line for each frame
--
--
    -float_dct
--
--
     forces ppmtompeg to use a more accurate, yet more
--computationally expensive version of the DCT.
--
--
    -gop gop_num
--
    
--causes ppmtompeg to encode only the numbered GOP (first GOP is 0).  The
--parameter file is the same as for normal usage.  The output file will be
--the normal output file with the suffix .gop.gop_num.
--ppmtompeg does not output any sequence information.
--
--
    -combine_gops
--
--
     causes ppmtompeg simply to combine some GOP files into a
--single MPEG output stream.  ppmtompeg inserts a sequence header
--and trailer.  In this case, the parameter file needs only to contain 
--the SIZE value, an output file, and perhaps a list of input GOP
--files (see below).
--
--If you don't supply a list of input GOP files is used, then
--ppmtompeg assumes you're using the same parameter file you used
--when you created the input (with the -gop option) and
--calculates the corresponding gop filenames itself.  If this is not the
--case, you can specify input GOP files in the same manner as normal
--input files -- except instead of using INPUT_DIR, INPUT, and
--END_INPUT, use GOP_INPUT_DIR, GOP_INPUT, and GOP_END_INPUT.  If no
--input GOP files are specified, then the default is to use the output
--file name with suffix .gop.gop_num, with gop_num
--starting from 0, as the input files.
--     
--
    Thus, unless you're mixing and matching GOP files from different
--sources, you can simply use the same parameter file for creating the
--GOP files (-gop) and for later turning them into an MPEG stream
--(-combine_gops).
--     
--
--
    -frames first_frame last_frame
--
--
    This option causes ppmtompeg to encode only the frames numbered
--first_frame to last_frame, inclusive.  The parameter
--file is the same as for normal usage.  The output will be placed in
--separate files, one per frame, with the file names being the normal
--output file name with the suffix .frame.frame_num.  No
--GOP header information is output.  (Thus, the parameter file need not
--include the GOP_SIZE value)
--
--
    Use ppmtompeg -combine_frames to combine these frames later into
--an MPEG stream.
--
--
--
    -combine_frames
--
--
     This option causes ppmtompeg simply to combine some
--individual MPEG frames (such as you might have created with an earlier
--run of ppmtompeg -frames) into a single MPEG stream.  Sequence
--and GOP headers are inserted appropriately.  In this case, the
--parameter file needs to contain only the SIZE value, the GOP_SIZE
--value, an output file, and perhaps a list of frame files (see below).
--
--
    The parameter file may specify input frame files in the same manner
--as normal input files -- except instead of using INPUT_DIR, INPUT, and
--END_INPUT, use FRAME_INPUT_DIR, FRAME_INPUT, and FRAME_END_INPUT. If
--no input frame files are specified, then the default is to use the
--output file name with suffix .frame.frame_num, with
--frame_num starting from 0, as the input files.
--     
--
--
--
    -nice
--
--
    This option causes ppmtompeg to run any remote processes
--"nicely," i.e.  at low priority.  (This is relevant only if you are
--running ppmtompeg in parallel mode.  Otherwise, there are no
--remote processes).  See 'man nice.'
--
--
    -max_machines num_machines
--
--
    This option causes ppmtompeg to use no more than
--num_machines machines as slaves for use in parallel encoding.
--
--
    -snr 
--
--
    This option causes ppmtompeg to include the signal-to-noise
--ratio in the reported statistics.  Prints SNR (Y U V) and peak SNR (Y
--U V) for each frame.  In summary, prints averages of luminance only
--(Y).  SNR is defined as 10*log(variance of original/variance of
--error).  Peak SNR is defined as 20*log(255/RMSE).  Note that
--ppmtompeg runs a little slower when you use this option.
--
--
    -mse
--
--
    This option causes ppmtompeg to report the mean squared
--error per block.  It also automatically reports the quality of the
--images, so there is no need to specify -snr then.
--
--
    -bit_rate_info rate_file
--
--
     This option makes ppmtompeg write bit rate information
--into the file rate_file.  Bit rate information is bits per frame, and
--also bits per I-frame-to-I-frame.
--
--
    -mv_histogram 
--
--
     This option causes ppmtompeg to print a histogram of the
--motion vectors as part of statistics.  There are three histograms --
--one for P frame, one for forward B frame, and one for backward B frame
--motion vectors.
--
--
    The output is in the form of a matrix, each entry corresponding to one
--motion vector in the search window. The center of the matrix
--represents (0,0) motion vectors.
--
--
    -debug_sockets
--
--
    This option causes ppmtompeg to print to Standard Output
--messages that narrate the communication between the machines when you run
--ppmtompeg in parallel mode.
--
--
    -debug_machines
--
--
    This option causes ppmtompeg to print to Standard Output
--messages that narrate the progress of the conversion on the various
--machines when you run ppmtompeg in parallel
--mode.
--     
--
    
--
--
    PARAMETER FILE
    
--
--
    The parameter file must contain the following
--lines (except when using the -combine_gops or -combine_frames
--options):
--
--
    
--
--
    PATTERN pattern
--
--
    This statement specifies the pattern (sequence) of I frames, P frames,
--and B frames.  pattern is just a sequence of the letters I, P, and
--B with nothing between.  Example:
--
--
    --    PATTERN IBBPBBPBBPBBPBB
--
         
--
--
    See I Frames, P Frames, B Frames.
--
--
    OUTPUT output file
--
    This names the file where the output MPEG stream goes.
--     
--
    INPUT_DIR directory
--
--
    This statement tells where the input images (frames) come from.
--If each frame is in a separate file, directory is the directory
--where they all are.  You may use . to refer to the current 
--directory.  A null directory refers to the root directory of the
--system file tree.
--
--
    To have ppmtompeg read all the frames serially from Standard 
--Input, specify
--
    --    INPUT_DIR stdin
--
    
--
--
    INPUT
--
    
--This line must be followed by a list of the input files (in display order)
--and then the line END_INPUT.
--
--
    There are three types of lines between INPUT and END_INPUT.  First,
--a line may simply be the name of an input file.  Second, the line
--may be of the form single_star_expr
--[x-y].
--single_star_expr can have a single * in it.  It is
--replaced by all the numbers between x and y inclusive.  So, for
--example, the line tennis*.ppm [12-15] refers to the files
--tennis12.ppm, tennis13.ppm, tennis14.ppm, tennis15.ppm.
--
--
    Uniform zero-padding occurs, as well.  For example, the line
--football.*.ppm [001-130] refers to the files football.001.ppm,
--football.002.ppm, ..., football.009.ppm, football.010.ppm, ...,
--football.130.ppm.
--
--
    The third type of line is: single_star_expr
--[x-y+s], where the
--line is treated exactly as above, except that we skip by s.  Thus, the
--line football.*.ppm [001-130+4] refers to the files
--football.001.ppm, football.005.ppm, football.009.ppm,
--football.013.ppm, etc.
--
--
    Furthermore, a line may specify a shell command to execute to
--generate lines to be interpreted as described above, as if those lines
--were in the parameter file instead.  Use back ticks, like in the
--Bourne Shell, like this:
--
--
    --    `cat myfilelist`
--
    
--
--
    
--If input is from Standard Input (per the INPUT_DIR statement), 
--ppmtompeg ignores the INPUT/END_INPUT block, but
--it still must be present.
--     
--
    BASE_FILE_FORMAT {PPM | PNM | YUV | 
--     JPEG | JMOVIE}
--
--
    ppmtompeg must convert all input files to one of the
--following formats as a first step of processing: PNM, YUV, JPEG(v4),
--or JMOVIE.  (The conversion may be trivial if your input files are
--already in one of these formats).  This line specifies which of the
--four formats.  PPM is actually a subset of PNM.  The separate
--specification is allowed for backward compatibility.  Use PNM instead
--of PPM in new applications.
--
--
    INPUT_CONVERT conversion_command
--
--
    You must specify how to convert a file to the base file format.
--If no conversion is necessary, then you would just say:
--
--     
    --     INPUT_CONVERT *
--     
    
--     
--
    Otherwise, conversion_command is a shell command that causes
--an image in the format your specified with BASE_FILE_FORMAT to
--be written to Standard Output.  ppmtompeg executes the command
--once for each line between INPUT and END_INPUT (which is
--normally, but not necessarily, a file name).  In the conversion
--command, ppmtompeg replaces each '*' with the contents of that
--line.
--     
--     If you had a bunch of gif files, you might say:
--     
    --     INPUT_CONVERT giftopnm *
--     
    
--
--     If you have a bunch of separate a.Y, a.U, and a.V files (where
--     the U and V have already been subsampled), then you might say:
--
--     
    --     INPUT_CONVERT cat *.Y *.U *.V
--     
    
--
--
    Input conversion is not allowed with input from stdin, so use
--
--     
    --     INPUT_CONVERT *
--     
    
--
--as described above.
--     
--
    SIZE widthxheight
--
--
    
--
--
    width and height are the width and height of each
--frame in pixels.
--
--
    When ppmtompeg can get this information from the input image
--files, it ignores the SIZE parameter and you may omit it.
--
--
    When the image files are in YUV format, the files don't contain
--dimension information, so SIZE is required.
--
--
    When ppmtompeg is running in parallel mode, not all of the
--processes in the network have access to the image files, so
--SIZE is required and must give the same dimensions as the
--input image files.
--
--
    YUV_SIZE widthxheight
--
--
    This is an obsolete synonym of SIZE.
--
--
    YUV_FORMAT {ABEKAS | PHILLIPS | UCB |
--                      EYUV | pattern}
--
--
    This is meaningful only when BASE_FILE_FORMAT specifies
--YUV format, and then it is required.  It specifies the sub-format of
--the YUV class.
--
--
--
    GOP_SIZE n
--
--
    n is the number of frames in a Group of Pictures.  Except that
--because a GOP must start with an I frame, ppmtompeg makes a GOP as
--much longer than n as it has to to make the next GOP start with an
--I frame. 
--
--
    Normally, it makes sense to make your GOP size a multiple of your
--pattern length (the latter is determined by the PATTERN parameter file
--statement).
--
--
    See Group Of Pictures.
--
--
    SLICES_PER_FRAME n
--
    n is roughly the number of slices per frame.  Note, at
--least one MPEG player may complain if slices do not start at the left
--side of an image.  To ensure this does not happen, make sure the
--number of rows is divisible by SLICES_PER_FRAME.
--
--
    PIXEL {FULL | HALF} 
--
--
    use half-pixel motion vectors, or just full-pixel ones It is
--usually important that you use half-pixel motion vectors, because it
--results in both better quality and better compression.
--     
--
--
    RANGE n
--
    Use a search range of n pixels in each of the four directions
--from a subject pixel.  (So the search window is a square n*2 pixels
--on a side).
--
--
    PSEARCH_ALG {EXHAUSTIVE | TWOLEVEL |
--     SUBSAMPLE | LOGARITHMIC}
--
--
    This statement tells ppmtompeg what kind of search
--    technique (algorithm) to use for P frames.  You select the desired
--    combination of speed and compression.  EXHAUSTIVE gives the
--    best compression, but LOGARITHMIC is the fastest.
--    TWOLEVEL is an exhaustive full-pixel search, followed by a
--    local half- pixel search around the best full-pixel vector (the
--    PIXEL option is ignored for this search technique).
--
--
    BSEARCH_ALG {SIMPLE | CROSS2 | EXHAUSTIVE}
--
--
    This statement tells ppmtompeg what kind of search
--    technique (algorithm) to use for B frames.  SIMPLE means
--    find best forward and backward vectors, then interpolate.
--    CROSS2 means find those two vectors, then see what backward
--    vector best matches the best forward vector, and vice versa.
--    EXHAUSTIVE does an n-squared search and is
--    extremely slow in relation to the others (CROSS2
--    is about half as fast as SIMPLE).

    REFERENCE_FRAME {ORIGINAL | DECODED} 
    This
--statement determines whether ppmtompeg uses the original images
--or the decoded images when computing motion vectors.  Using decoded
--images is more accurate and should increase the playback quality of
--the output, but it makes the encoding take longer and seems to give
--worse compression.  It also causes some complications with parallel
--encoding. (see the section on parallel encoding).  One thing you can
--do as a trade-off is select ORIGINAL here, and lower the
--qscale (see QSCALE if the quality is not good enough.

    The following lines are optional:
--
--
    
--
--
    FORCE_ENCODE_LAST_FRAME
--
--
    This statement is obsolete.  It does nothing.
--
--
    Before Netpbm 10.26 (January 2005), ppmtompeg would drop
--trailing B frames from your movie, since a movie can't end with a B
--frame.  (See I Frames, P Frames, B Frames.)
--You would have to specify FORCE_ENCODE_LAST_FRAME to stop
--that from happening and get the same function that ppmtompeg
--has today.
--
--
--
    NIQTABLE
--
--
    This statement specifies a custom non-intra quantization table.
--If you don't specify this statement, ppmtompeg uses a default
--non-intra quantization table.
--
--
    
--The 8 lines immediately following NIQTABLE specify the quantization
--table.  Each line defines a table row and consists of 8 integers,
--whitespace-delimited, which define the table columns.
--
--
    IQTABLE
--
--
    This is analogous to NIQTABLE, but for the intra quantization table.
--
--
    ASPECT_RATIO ratio
--
--
    This statement specifies the aspect ratio for ppmtompeg to
--specify in the MPEG output.  I'm not sure what this is used for.
--
--
    ratio must be 1.0, 0.6735, 0.7031, 0.7615, 0.8055, 0.8437,
--0.8935, 0.9157, 0.9815, 1.0255, 1.0695, 1.0950, 1.1575, or 1.2015.
--
--
    FRAME_RATE rate
--
    This specifies the frame rate for ppmtompeg to specify in the
--MPEG output.  Some players use this value to determine the playback rate.
--
--
    rate must be 23.976, 24, 25, 29.97, 30, 50, 59.94, or 60.
--
--
    BIT_RATE rate
--
    This specifies the bit rate for Constant Bit Rate (CBR) encoding.
--
--
    rate must be an integer.
--
--
    BUFFER_SIZE size 
--
--
    This specifies the value
--ppmtompeg is to specify in the MPEG output for the Video
--Buffering Verifier (VBV) buffer size needed to decode the sequence.
--
--
    A Video Verifying Buffer is a buffer in which a decoder keeps the
--decoded bits in order to match the uneven speed of the decoding with
--the required constant playback speed.
--
--
    As ppmtompeg encodes the image, it simulates the decoding
--process in terms of how many bits would be in the VBV as each frame gets
--decoded, assuming a VBV of the size you indicate.  
--
--
    If you specify the WARN_VBV_UNDERFLOW statement,
--ppmtompeg issues a warning each time the simulation underflows
--the buffer, which suggests that an underflow would occur on playback,
--which suggests the buffer is too small.
--
--
    If you specify the WARN_VBV_OVERFLOW statement,
--ppmtompeg issues a warning each time the simulation overflows
--the buffer, which suggests that an overflow would occur on playback,
--which suggests the buffer is too small.
--
--
    WARN_VBV_UNDERFLOW
--
    WARN_VBV_OVERFLOW
--
--
    See BUFFER_SIZE.
--
--
    These options were new in Netpbm 10.26 (January 2005).  Before that,
--ppmtompeg issued the warnings always.
--
--
    
--
--
--The following statements apply only to parallel operation:
--
--
     
--
--
    PARALLEL
--
--
    This statement, paired with END PARALLEL, is what causes
--ppmtompeg to operate in parallel mode.  See Parallel Operation.
--
--
    END PARALLEL
--
--
    This goes with PARALLEL.
--
--
    PARALLEL_TEST_FRAMES n 
--
--
    The master starts off by measuring each slave's speed.  It does
--this by giving each slave n frames to encode and noting how
--long the slave takes to finish.  These are not just test frames,
--though -- they're real frames and the results become part of the
--output.
--ppmtompeg is old and measures time in undivided seconds, so
--to get useful timings, specify enough frames that it will take at
--least 5 seconds to process them.  The default is 10.
--
--
    If you specify FORCE_I_ALIGN, ppmtompeg will increase
--the test frames value enough to maintain the alignment.
--
--
    If there aren't enough frames for every slave to have the indicated
--number of test frames, ppmtompeg will give some slaves fewer.
--
--
--
    PARALLEL_TIME_CHUNKS t
--
--
    When you specify this statement, the master attempts to feed work
--to the slaves in chunks that take t seconds to process.  It uses
--the speed measurement it made when it started up (see PARALLEL_TEST_FRAMES)
--to decide how many frames to put in the chunk.  This statement obviously
--doesn't affect the first batch of work sent to each slave, which is the
--one used to measure the slave's speed.
--
--
    Smaller values of t increase communication, but improve load
--balancing.  The default is 30 seconds.
--
--
    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER,
--and PARALLEL_PERFECT.  PARALLEL_CHUNK_TAPER is usually best.
--
--
    PARALLEL_CHUNK_TAPER
--
--
    When you specify this statement, the master distributes work like
--with PARALLEL_TIME_CHUNKS, except that the master chooses the number
--of seconds for the chunks.  It starts with a large number and, as it
--gets closer to finishing the job, reduces it.  That way, it reduces
--scheduling overhead when precise scheduling isn't helpful, but still
--prevents a slave from finishing early after all the work has already
--been handed out to the other slaves, and then sitting idle while
--there's still work to do.
--
--
    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER,
--and PARALLEL_PERFECT.  PARALLEL_CHUNK_TAPER is usually best.
--
--
--
    PARALLEL_PERFECT
--
--
    If this statement is present, ppmtompeg schedules on the
--assumption that each machine is about the same speed.  The master will
--simply divide up the frames evenly between the slaves -- each
--slave gets the same number of frames.  If some slaves are faster than
--others, they will finish first and remain idle while the slower slaves
--continue.  
--
--
    This has the advantage of minimal scheduling overhead.  Where slaves
--have different speeds, though, it makes inefficient use of the fast
--ones.  Where slaves are the same speed, it also has the disadvantage
--that they all finish at the same time and feed their output to the
--single Combine Server in a burst, which makes less efficient use of
--the Combine Server and thus can increase the total elapsed time.
--
--
    You may specify only one of PARALLEL_TIME_CHUNKS, PARALLEL_CHUNK_TAPER,
--and PARALLEL_PERFECT.  PARALLEL_CHUNK_TAPER is usually best.
--
--
    RSH remote_shell_command
--
--
    ppmtompeg executes the shell command
--remote_shell_command to start a process on another machine.
--The default command is rsh, and whatever command you specify
--must have compatible semantics.  ssh is usually compatible.
--The command ppmtompeg uses is one like this:
--ssh remote.host.com -l username shellcommand.
--
--
    Be sure to set up .rhosts files or SSH key authorizations
--where needed.  Otherwise, you'll have to type in passwords.
--
--
    On some HP machines, rsh is the restricted shell, and you want
--to specify remsh.
--
--
    FORCE_I_ALIGN
--
--
    This statement forces each slave to encode a chunk of frames which
--is a multiple of the pattern length (see PATTERN).  Since the
--first frame in any pattern is an I frame, this forces each chunk
--encoded by a slave to begin with an I frame.
--
--
    This document used to say there was an argument to
--FORCE_I_ALIGN which was the number of frames ppmtompeg
--would use (and was required to be a multiple of the pattern length).
--But ppmtompeg has apparently always ignored that argument, and
--it does now.
--
--
    KEEP_TEMP_FILES
--
--
    This statement causes ppmtompeg not to delete the temporary
--files it uses to transmit encoded frames to the combine server.  This
--means you will be left with a file for each frame, the same as you
--would get with the -frames option.  
--
--
    This is mostly useful for debugging.
--
--
    This works only if you're using a shared filesystem to communicate
--between the servers.
--
--
    This option was new in Netpbm 10.26 (January 2005).
--
--
    
--
--
--
    Parameter File Notes
    
--
--
     If you use the -combine_gops option, then you need to specify
--only the SIZE and OUTPUT values in the parameter file.  In
--addition, the parameter file may specify input GOP files in the same
--manner as normal input files -- except instead of using INPUT_DIR,
--INPUT, and END_INPUT, use GOP_INPUT_DIR, GOP_INPUT, and GOP_END_INPUT.
--If you specify no input GOP files, then ppmtompeg uses by default the
--output file name with suffix .gop.gop_num, with gop_num
--starting from 0, as the input files. 
--
--
    If you use the -combine_frames option, then you need to
--specify only the SIZE, GOP_SIZE, and OUTPUT values in the
--parameter file.  In addition, the parameter file may specify input
--frame files in the same manner as normal input files -- except instead
--of using INPUT_DIR, INPUT, and END_INPUT, use FRAME_INPUT_DIR,
--FRAME_INPUT, and FRAME_END_INPUT.  If no input frame files are
--specified, then the default is to use the output file name with suffix
--.frame.frame_num, with frame_num starting from 0,
--as the input files.
--
--
    Any number of spaces and tabs may come between each option and value.  Lines
--beginning with # are ignored.  Any other lines are ignored except for
--those between INPUT and END_INPUT.  This allows you to use the same
--parameter file for normal usage and for -combine_gops and
---combine_frames.
--
--
    The file format is case-sensitive so all keywords should be in
--upper case.
--
--
    The statements may appear in any order, except that the order within
--a block statement (such as INPUT ... END INPUT) is significant.
--
--
    ppmtompeg is prepared to handle up to 16 B frames between
--reference frames when encoding with input from stdin.  (To build a
--modified ppmtompeg with a higher limit, change the constant
--B_FRAME_RUN in frame.c and recompile).
--
--
    GENERAL USAGE INFORMATION
    
--
--
    Qscale
    
--
--
    The quantization scale values (qscale) give a trade-off between
--quality and compression.  Using different Qscale values has very little
--effect on speed.  The qscale values can be set separately for I, P, and
--B frames.
--
--
    You select the qscale values with the IQSCALE,
--PQSCALE, and BSCALE parameter file statements.
--
--
    A qscale value is an integer from 1 to 31.  Larger numbers give
--better compression, but worse quality.  In the following, the quality
--numbers are peak signal-to-noise ratio, defined as:
--signal-to-noise formula
--where MSE is the mean squared error.

    Search Techniques
    
--     
--
    There are several different motion vector search techniques
--available.  There are different techniques available for P frame
--search and B frame search. Using different search techniques present
--little difference in quality, but a large difference in compression
--and speed.
--     
--
    There are 4 types of P frame search: Exhaustive, TwoLevel,
--SubSample, and Logarithmic.
--     
--
    There are 3 types of B frame search: Exhaustive, Cross2, and
--Simple.
--     
--The recommended search techniques are TwoLevel and Logarithmic for
--P frame search, and Cross2 and Simple for B frame search. Here are
--some numbers comparing the different search methods:

    Select the search techniques with the PSEARCH_ALG and

--
--
--
    Group Of Pictures (GOP)
    
--
--
    A Group of Pictures (GOP) is a roughly independently decodable
--sequence of frames.  An MPEG video stream is made of one or more
--GOP's.  You may specify how many frames should be in each GOP with the
--GOP_SIZE parameter file statement.  A GOP always starts with an
--I frame.
--
--
    Instead of encoding an entire sequence, you can encode a single
--GOP.  To do this, use the -gop command option.  You can later
--join the resulting GOP files at any time by running ppmtompeg
--with the -combine_gops command option.
--     
--     
--
    Slices
    
--
--
    A slice is an independently decodable unit in a frame.  It can be
--as small as one macroblock, or it can be as big as the entire frame.
--Barring transmission error, adding slices does not change quality or
--speed; the only effect is slightly worse compression.  More slices are
--used for noisy transmission so that errors are more recoverable. Since
--usually errors are not such a problem, we usually just use one slice
--per frame.
--     
--
    Control the slice size with the SLICES_PER_FRAME parameter
--file statement.
--
--
    Some MPEG playback systems require that each slice consist of whole
--rows of macroblocks.  If you are encoding for this kind of player, if
--the height of the image is H pixels, then you should set the
--SLICES_PER_FRAME to some number which divides H/16.  For example, if
--the image is 240 pixels (15 macroblocks) high, then you should use
--only 15, 5, 3, or 1 slices per frame.
--     
--
    Note: these MPEG playback systems are really wrong, since the MPEG
--standard says this doesn't have to be so.
--
--
--
--
    Search Window
    
--     
--
    The search window is the window in which ppmtompeg searches
--for motion vectors.  The window is a square.  You can specify the size
--of the square, and whether to allow half-pixel motion vectors or not,
--with the RANGE and PIXEL parameter file statements.
--
--
    I Frames, P Frames, B Frames
    
--
--
    In MPEG-1, a movie is represented as a sequence of MPEG frames,
--each of which is an I Frame, a P Frame, or a B Frame.  Each represents
--an actual frame of the movie (don't get confused by the dual use of
--the word "frame."  A movie frame is a graphical image.  An MPEG frame
--is a set of data that describes a movie frame).
--
--
    An I frame ("intra" frame) describes a movie frame in isolation --
--without respect to any other frame in the movie.  A P frame
--("predictive" frame) describes a movie frame by describing how it
--differs from the movie frame described by the latest preceding I  or
--P frame.  A B frame ("bidirectional" frame) describes a movie frame by
--describing how it differs from the movie frames described by the
--nearest I or P frame before and after it.
--
--
    Note that the first frame of a movie must be described by an I
--frame (because there is no previous movie frame) and the last movie
--frame must be described by an I or P frame (because there is no
--subsequent movie frame).
--
--
    Beyond that, you can choose which frames are represented by which
--types.  You specify a pattern, such as IBPBP and ppmtompeg
--simply repeats it over and over throughout the movie.  The pattern
--affects speed, quality, and stream size.  Here is a chart which shows
--some of the trade-offs:

    A standard sequence is IBBPBBPBBPBBPBB.
--     
--
    Select the sequence with the PATTERN parameter file statement.
--
--
    Since the last MPEG frame cannot be a B frame (see above), if the
--pattern you specify indicates a B frame for the last movie frame of
--the movie, ppmtompeg makes it an I frame instead.
--
--
    Before Netpbm 10.26 (January 2005), ppmtompeg instead drops
--the trailing B frames by default, and you need the
--FORCE_ENCODE_LAST_FRAME parameter file statement to make it do
--this.
--
--
    The MPEG frames don't appear in the MPEG-1 stream in the same order that
--the corresponding movie frames appear in the movie -- the B frames come after
--the I and P frames on which they are based.  For example, if the movie is
--4 frames that you will represent with the pattern IBBP, the MPEG-1 stream
--will start with an I frame describing movie frame 0.  The next frame in
--the MPEG-1 stream is a P frame describing movie frame 3.  The last two
--frames in the MPEG-1 stream are B frames describing movie frames 1 and 2,
--respectively.
--
--
--
    Specifying Input and Output Files
     
--
--
    Specify the input frame images with the INPUT_DIR,
--INPUT, END_INPUT, BASE_FILE_FORMAT,
--SIZE, YUV_FORMAT and INPUT_CONVERT parameter
--file statements.
--
--
    Specify the output file with the OUTPUT parameter file statement.
--
--
--
    Statistics
    
--
--
    ppmtompeg can generate a variety of statistics about the 
--encoding.  See the -stat, -snr, -mv_histogram,
---quiet, -no_frame_summary, and -bit_rate_info
--options.
--     
--
--
    PARALLEL OPERATION
    
--
--
    You can run ppmtompeg on multiple machines at once, encoding
--the same MPEG stream.  When you do, the machines are used as shown in
--the following diagram.  We call this "parallel mode."
--
--
    ppmtompeg-par.gif
--
--
    To do parallel processing, put the statement
--
--
    --    PARALLEL
--
    
--
--in the parameter file, followed by a listing of the machines, one
--machine per line, then
--
--
    --    END_PARALLEL
--
    
--
--Each of the machine lines must be in one of two forms.  If the machine
--has filesystem access to the input files, then the line is:
--
--
    
--machine user executable
--
--
    The executable is normally ppmtompeg (you may need to give
--the complete path if you've built for different architectures).  If
--the machine does not have filesystem access to the input files, the line
--is:
--
--
    REMOTE machine user executable
--parameter file
--
--
    The -max_machines command option limits the number of
--machines ppmtompeg will use.  If you specify more machines in
--the parameter file than -max_machines allows, ppmtompeg
--uses only the machines listed first.  This is handy if you want to
--experiment with different amounts of parallelism.
--
--
    In general, you should use full path file names when describing
--executables and parameter files.  This includes the parameter
--file argument on the original invocation of ppmtompeg.
--
--
    All file names must be the same on all systems (so if e.g. you're
--using an NFS filesystem, you must make sure it is mounted at the same
--mountpoint on all systems).
--
--
    Because not all of the processes involved in parallel operation
--have easy access to the input files, you must specify the SIZE
--parameter file statement when you do parallel operation.
--
--
    The machine on which you originally invoke ppmtompeg is the
--master machine.  It hosts a "combine server,", a
--"decode server," and a number of "i/o servers,"
--all as separate processes.  The other machines in the network (listed
--in the parameter file) are slave machines.  Each hosts a single
--process that continuously requests work from the master and does it.
--The slave process does the computation to encode MPEG frames.  It
--processes frames in batches identified by the master.
--
--
    The master uses a remote shell command to start a process on a
--slave machine.  By default, it uses an rsh shell command to do
--this.  But use the RSH parameter file statement to control
--this.  The shell command the master executes remotely is
--ppmtompeg, but with options to indicate that it is to perform
--slave functions.
--
--
    The various machines talk to each other over TCP connections.  Each
--machine finds and binds to a free TCP port number and tells its
--partners the port number.  These port numbers are at least 2048.
--
--
    Use the PARALLEL_TEST_FRAMES, PARALLEL_TIME_CHUNKS, and
--PARALLEL_PERFECT parameter file statements to control the way the
--master divides up work among the slaves.
--
--
    Use the -nice command option to cause all slave processes to run
--"nicely," i.e. as low priority processes.  That way, this substantial and
--long-running CPU load will have minimal impact on other, possibly
--interactive, users of the systems.
--
--
    SPEED
    
--
--
    Here is a look at ppmtompeg speed, in single-node (not parallel)
--operation:

    Compression Speed

--1A macroblock is a 16x16 pixel square
--
--
    The measurements in the table are with inputs and outputs via a
--conventional locally attached filesystem.  If you are using a network
--filesystem over a single 10 MB/s Ethernet, that constrains your speed more
--than your CPU speed.  In that case, don't expect to get better than 4
--or 5 frames per second no matter how fast your CPUs are.
--
--
    Network speed is even more of a bottleneck when the slaves do not
--have filesystem access to the input files -- i.e. you declare them
--REMOTE.
--
--
    Where I/O is the bottleneck, size of the input frames can make a big
--difference.  So YUV input is better than PPM, and JPEG is better than
--both.
--
--
    When you're first trying to get parallel mode working, be sure to
--use the -debug_machines option so you can see what's going on.
--Also, -debug_sockets can help you diagnose communication
--problems.

+Include "pm.h" for the declaration of the overflow_add function.  This
+avoids an implicit function declaration.  Future C compilers will
+require that all functions are declared explicitly.  Implicit function
+declarations are a language feature that was removed in 1999.
+
+Likewise, include "pm.h" for the newly added declarations of realloc2.
+This fixes a pointer truncation bug in pjtoppm.
+
+Both issues are specific to downstream patches.

Subject: [PATCH 27/42] Fix flatpak build

When built for flatpaks, this will use the /app prefix, but netpbm's
dependencies are part of the runtime which is in /usr.  Therefore,
installation path macros must be used when installing the package but
not to refer to dependencies.

Subject: [PATCH 30/42] GCC 14 compatibility fixes

Drop netpbm-cmuwtopbm.patch because of an out-of-bounds stack write.
This is correctly reported by GCC 14 as a type error.

It looks like the issue was fixed upstream by adding an (uint32_t)
cast to the magic number check a few lines below (not shown in
the patch added in commit 7d3e28cc83e676c7e21524889fa2 downsteam).

Also stub out converter/other/jpeg2000/libjasper_compat.c because
it is broken.  Fixes another GCC 14 compatibility issue.
