while playing with some new hardware, I found it's running a forked mplayer -- and it looks like they're following the GPL. The maintainer's page is here: http://atty.jp/?Zaurus/mplayer Unfortunately it's mostly in Japanese, so it's hard to figure out any details. Their code looks quite interesting (at least to those of us w/ ARM CPUs). The patches I've attached are the patches from atty.jp with a couple of modifications by myself: - ported to current CVS - reverted their change of removing SNOW support from ffmpeg - cleaned up their bswap mess - removed DOS-style linebreaks from various files patch by (Bernhard Rosenkraenzer: bero, arklinux org) Originally committed as revision 4311 to svn://svn.ffmpeg.org/ffmpeg/trunkpull/126/head
