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 Berkeley 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. The decoder implements the standard described in the Committee Draft ISO/IEC CD 11172 dated December 6, 1991 which is sometimes refered to as "Paris Format." The code has been compiled 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 Linux If you decide to port the code to a new architecture, please let us know if there are any significant changes, so that we can incorporate them into our sources. 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. Our future plans include porting the decoder to run on other platforms, integrating it into a video playback system that supports real-time synchronization and audio streams, and further experiments to improve the performance of the decoder. 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.lib Reporting bugs: If you find any bugs in this software, please send them to email@example.com. 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 program ACKNOWLEDGEMENTS: We gratefully thank Hewlett-Packard, Fujitsu, the Semiconductor Research Corporation for financial support. We also want to thank the following people for their help: Tom Lane of the Independent JPEG Group provided us with the basic inverse DCT code used by our player.
