From the README: MPEG-1 Video Software Encoder (Version 1.5; February 1, 1995) Lawrence A. Rowe, Kevin Gong, Eugene Hung, Ketan Patel, Steve Smoot and Dan Wallach Computer Science Division-EECS, Univ. of Calif. at Berkeley This directory contains the freely distributed Berkeley MPEG-1 Video Encoder. The encoder implements the standard described in the ISO/IEC International Standard 11172-2. The code has been compiled and tested on the following platforms: DECstation 5000 and Alpha HP PA-RISC (HP/UX 9.X) (i.e., HP 9000/7XX and 9000/3XX) SGI Indigo running IRIX 5.0.1 Sun Sparc (SunOS 4.X) This is *not* bug-free software. In particular, I've had problems using odd-sized input frames. Other than that, it works OK. eric. erich@FreeBSD.org
