This directory contains Python and C code we wrote while we had a
framegrabber board on loan from SGI.

cam.py network real-time tv broadcast; see tv.py
usage: cam [packfactor [host]]
specifying 'all' for host broadcasts
camcorder.py record video movies or make snapshots (in movie format)
usage: camcorder [-c] [-a audiohost [-s]] [moviefile]
-c color (default b/w, packfactor = 2)
-a audiohost syncaudio is running on audiohost
-s start syncaudio (on audiohost)
moviefile (default film.video)
keyboard commands:
s stop grabbing (single step if already stopped)
c continuous grabbing
r start recording
p pause recording (record single frame if paused)
ESC quit
statit.py various statistics operations on movie files
syncaudio.py record audio synchronized with camcorder -a
usage: syncaudio videohost soundfile
soundfile format: 16 bits, 16khz, mono
tv.py receiver for transmissions from cam.py
video.py player for movies recorded by camcorder.py
usage: video [moviefile [soundfile]]
default moviefile is film.video
default sound is no sound
vinfo.py print a summary of a movie file
vtime.py virtual time module imported by syncaudio.py and camcorder.py
These are C programs, either for efficiency or because they need to
link with a C library.
squash.c make a movie smaller by averaging pixels
usage: squash factor [bits] <moviefile >newmoviefile
factor x and y compression factor
bits #bits left per sample in result (default 8)
squash2.c make a movie smaller by dropping pixels
usage: squash2 factor <moviefile >newmoviefile
factor x and y compression factor
tomono.c like squash2 but outputs a monochrome movie
v2i.c convert the first image of a movie file to SGI .rgb format
