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

  - preliminary support for mpeg4-aac rtp payload (no interleaving support)
  - use udp transport as default (makes more sense with rtp, doesn't it ?)
  - some code factorization, so adding support for new rtp payload will be easier
  (I hope ;-)
