Thanks I also checked this code. As far as I understand it, most of the
improvements from this forked version are already included into ffmpeg
(revision 4311). The things that are left are some Zaurus specific video
drivers and patches for libmpeg2 code.
I'm porting MPlayer to Nokia 770: https://garage.maemo.org/projects/mplayer/
The thing that can provide the most improvement right now is video output code
(make use of hardware YUV support). So it will probably still take a while
before I actually start optimizing ffmpeg using armv5te assembler.
