Hmmm... perhaps it *does* have to do with MPEG-LA patents? I found the following in the bbMPEG source: /* Copyright (C) 1996, MPEG Software Simulation Group. All Rights Reserved. */ /* * Disclaimer of Warranty [snip] * The MPEG Software Simulation Group does not represent or warrant that the * programs furnished hereunder are free of infringement of any third-party * patents. * * Commercial implementations of MPEG-1 and MPEG-2 video, including shareware, * are subject to royalty fees to patent holders. Many of these patents are * general enough such that they are unavoidable regardless of implementation * design. :mad: 'Course, this doesn't say anything about *free* implementations... :confused:
