- # parameter file template with lots of comments to assist you
- #
- # you can use this as a template, copying it to a separate file then modifying
- # the copy
- #
- #
- # any line beginning with '#' is a comment
- #
- # no line should be longer than 255 characters
- #
- #
- # general format of each line is:
- # <option> <spaces and/or tabs> <value>
- #
- # lines can generally be in any order
- #
- # only exception is the option 'INPUT' which must be followed by input
- # files in the order in which they must appear, followed by 'END_INPUT'
- #
- # <option> MUST be in UPPER CASE
- #
-
- PATTERN IBBPBBI
- OUTPUT output.mpg
-
- # mpeg_encode really only accepts 3 different file formats, but using a
- # conversion statement it can effectively handle ANY file format
- #
- # you must specify whether you will convert to PNM or PPM or YUV format
- # (must be upper case)
- #
- BASE_FILE_FORMAT YUV
-
- #
- # if YUV format (or using parallel version), must provide width and height
- # YUV_SIZE widthxheight
- # this option is ignored if BASE_FILE_FORMAT is PPM or PNM and you're running
- # on just one machine
- #
- YUV_SIZE 352x240
-
- # the conversion statement
- #
- # Each occurrence of '*' will be replaced by the input file
- #
- # e.g., if you have a bunch of GIF files, then this might be:
- # INPUT_CONVERT giftoppm *
- #
- # e.g., if you have a bunch of files like a.Y a.U a.V, etc., then:
- # INPUT_CONVERT cat *.Y *.U *.V
- #
- # e.g., if you are grabbing from laser disc you might have something like
- # INPUT_CONVERT goto frame *; grabppm
- # 'INPUT_CONVERT *' means the files are already in the base file format
- #
- INPUT_CONVERT *
-
- # number of frames in a GOP.
- #
- # since each GOP must have at least one I-frame, the encoder will find the
- # the first I-frame after GOP_SIZE frames to start the next GOP
- #
- # later, will add more flexible GOP signalling
- #
- GOP_SIZE 6
-
- # number of slices in a frame
- #
- # 1 is a good number. another possibility is the number of macroblock rows
- # (which is the height divided by 16)
- #
- SLICES_PER_FRAME 1
-
- # directory to get all input files from (makes this file easier to read)
- INPUT_DIR ../input/tennis
-
- INPUT
- # '*' is replaced by the numbers 01, 02, 03, 04
- # if I instead do [01-11], it would be 01, 02, ..., 09, 10, 11
- # if I instead do [1-11], it would be 1, 2, 3, ..., 9, 10, 11
- # if I instead do [1-11+3], it would be 1, 4, 7, 10
- # the program assumes none of your input files has a name ending in ']'
- # if you do, too bad!!!
- #
- #
- stennis.*.yuv [0-23]
- # can have more files here if you want...there is no limit on the number
- # of files
- END_INPUT
-
-
-
- # all of the remaining options have to do with the motion search and qscale
-
- # FULL or HALF -- must be upper case
- PIXEL HALF
-
- # means +/- this many pixels
- RANGE 10
-
- # this must be one of {EXHAUSTIVE, SUBSAMPLE, LOGARITHMIC}
- PSEARCH_ALG LOGARITHMIC
-
- # this must be one of {SIMPLE, CROSS2, EXHAUSTIVE}
- #
- # note that EXHAUSTIVE is really, really, really slow
- #
- BSEARCH_ALG CROSS2
-
- #
- # these specify the q-scale for I, P, and B frames
- # (values must be between 1 and 31)
- #
- IQSCALE 8
- PQSCALE 10
- BQSCALE 25
-
- # this must be ORIGINAL or DECODED
