This directory contains source for various utility programs.
To build everything, first edit the Makefile to include the appropriate
Tcl/Tk libraries, and change anything you need to. Then type 'make.'
None of the programs do very much error checking, so beware.
PROGRAM: encode_sh
USAGE: encode_sh -f encode.tcl
DESCRIPTION: a very simple Tcl/Tk interface to the mpeg_encode program.
For it to work, mpeg_encode must be in your path.
BUGS: Only allows files from one directory.
PROGRAM: ppmtoyuv
USAGE: ppmtoyuv < input.ppm > output.yuv
DESCRIPTION: converts a PPM file to a YUV file (encoder format)
PROGRAM: blockppmtoyuv
USAGE: blockppmtoyuv base start end skip
DESCRIPTION: will ppmtoyuv all files baseN where N runs from start to end,
skipping by skip. New files will end in .yuv. Program
DELETES the original files.
All of the following programs require a Parallax XVideo card to run:
PROGRAM: playone
USAGE: playone filename width height start end outbase [quality]
DESCRIPTION: converts an Xvideo JPEG movie file (filename) of given
(width, height) into a bunch of ppm files. Only does the
frames numbered start to end (frames begin at 1). Output
file names are outbaseN.ppm where N is the frame number.
BUGS: may crash after 200 or 300 frames
PROGRAM: playskip
USAGE: playskip filename width height start nth outbase [quality]
DESCRIPTION: same as playone, except does every nth frame beginning with
start until the end of the movie.
BUGS: may crash after 200 or 300 frames
PROGRAM: xvideotojpeg
USAGE: xvideotojpeg filename width height start end outbase [quality]
DESCRIPTION: same as playone, except instead of outputting ppm files,
outputs JPEG files.
BUGS: may crash after 200 or 300 frames
PROGRAM: xvidtoyuv
USAGE: xvidtoyuv filename width height start nth outbase [quality]
DESCRIPTION: same as playskip, except instead of outputting ppm files,
outputs yuv files.
BUGS: may crash after 200 or 300 frames
