This archive will expand into the mpeg directory.
The archive compiles clean on QNX.

This directory contains a public domain MPEG video software
decoder. The decoder is implemented as a library that will
take a video stream and display it in an X window on an 8, 24
or 32 bit deep display.  The main routine is supplied to
demonstrate the use of the decoder library. Several dithering
algorithms are supplied based on the Floyd-Steinberg, ordered
dither, and half-toning algorithms that tradeoff quality and
performance. Neither the library nor the main routine handle
real-time synchronization or audio streams.

This directory contains everything required to build and
display video. We have included source code, a makefile, an Imakefile,
installation instructions, and a man page. Data files can
be obtained from the same ftp site this was located in.
See the INSTALL file for instructions on how to
compile and run the decoder. 

The data files were produced by XING. XING data does not take
advantage of P or B frames (ie, frames with motion compensation). 
Performance of the player on XING data is significantly slower 
(half or less) than the performance when motion compensated MPEG 
data is decoded. We are very interested in running the software 
on other MPEG streams.  Please contact us if you have a stream 
that does not decode correctly. Also, please send us new streams
produced by others that do utilize P and B frames.

NOTE: One particular XING data file: raiders.mpg, is not a 
valid MPEG stream since it does not contain a sequence
header.
