Do you really think MPlayer would rely on proprietary software as a core
component? FFMPEG is released under the GPL. Unfortunately, there are
patents covering MPEG-4, so no use of it can be completely free. We
might be violating patents (in the US anyway) every time we use XviD or
lavc. Ironically, it might be safer legally to use DivX then either XviD
or lavc, since DivXNetworks may have taken care of MPEG licensing. Does
anyone here know the actual legal status of using each of these codecs?
