MPEG Video Software Decoder                  (Version 2.3; March 1996) Lawrence A. Rowe, Ketan Patel, Brian Smith, Steve Smoot, and Eugene Hung      Computer Science Division-EECS, Univ. of Calif. at BerkeleyThis directory contains a public domain MPEG video softwaredecoder. The decoder is implemented as a library that willtake a video stream and display it in an X window on an 8, 24or 32 bit deep display.  The main routine is supplied todemonstrate the use of the decoder library. Several ditheringalgorithms are supplied based on the Floyd-Steinberg, ordereddither, and half-toning algorithms that tradeoff quality andperformance. Neither the library nor the main routine handlereal-time synchronization or audio streams.The decoder implements the standard described in the Committee Draft ISO/IEC CD 11172 dated December 6, 1991 which issometimes refered to as "Paris Format." The code has beencompiled and tested on the following platforms: HP PA-RISC (HP/UX 9.X, X11R5) (i.e., HP 9000/7XX and 9000/3XX) Sun Sparc (SunOS 4.X, Solaris) DECstation 5000 and Alpha Silicon Graphics Indigo MIPS RISC/os 4.51 LinuxIf you decide to port the code to a new architecture, please letus know if there are any significant changes, so that we can incorporatethem into our sources. This directory contains everything required to build anddisplay video. We have included source code, a makefile, an Imakefile,installation instructions, and a man page. Data files canbe obtained from the same ftp site this was located in.See the INSTALL file for instructions on how tocompile and run the decoder. Our future plans include porting the decoder to run on otherplatforms, integrating it into a video playback system thatsupports real-time synchronization and audio streams, andfurther experiments to improve the performance of thedecoder. Vendors or other organizations interested in supporting this research or discussing other aspects of this project should contact Larry Rowe at Rowe@CS.Berkeley.EDU.The decoder can not be compiled as a library, see README.libReporting bugs:    If you find any bugs in this software, please send them to    mpeg-bugs@plateau.cs.berkeley.edu.  Since this software    is unsupported, we make no guarantees about how long it will    take to fix the bug, or if it will be fixed at all.  Bug fixes    will be cheerfully accepted.  Please include as much detailed    information as possible, including:	1) the version number of the program you are using (cf. VERSION)	2) the data file that caused the bug (if possible)	3) the OS version and machine type you ran the program on	4) the compiler used to compile the programACKNOWLEDGEMENTS:	We gratefully thank Hewlett-Packard, Fujitsu, the Semiconductor	Research Corporation for financial support.
