glmpeg_play is an SGI-specific MPEG player based on the Berkeley
decoder (available as mpeg_play-2.0.tar.Z via anonymous ftp from
s2k-ftp.cs.berkeley.edu, in the directory /pub/multimedia/mpeg).  The
MPEG decoding code is taken more-or-less directly from the Berkeley
program; the main strength of glmpeg_play is its its ability to buffer
frames to disk or memory in order to speed up playback, and its wide
range of playback options.  These include pause, single-step and
continuous play in either direction, jump to beginning/end of movie,
automatic resizing of the movie with its window, and a full-screen
mode.

glmpeg_play is distributed in source and IRIX binary form.  The binary
included in the glmpeg_play-1.1.tar file was compiled under IRIX 4.0.5
with the shared version of the GL library, with the -O4 optimization
option.

To compile glmpeg_play, you will need the MPEG Library, which was
developed in conjunction with glmpeg_play and is essentially the
Berkeley decoding engine with (hopefully) all X11-specific stuff
removed, and a useful, semi-documented front-end put on.  If the MPEG
Library is placed in "../mpeg_lib" with respect to glmpeg_play, then
you won't have to change the makefile in order to build glmpeg_play.

glmpeg_play and the MPEG Library are available via anonymous FTP from
yorick.mni.mcgill.ca in /pub/mpeg, along with several other
MPEG-related goodies (the original Berkeley X11 player, a version of
the X11 player with a Motif front end, and an encoder/decoder from the
Portable Video Research Group at Stanford).

glmpeg_play and the MPEG Library are both freely redistributable in
source and binary form, as long as the copyright notice and associated
legalese are retained; see any of the source files for details.
