Probably it is a good idea to consolidate efforts and try to submit some of the useful ARM related patches upstream:
http://lists.mplayerhq.hu/pipermail/ffmpeg...ust/014460.html
http://lists.mplayerhq.hu/pipermail/mplaye...ber/046207.html

I can only test MPlayer on Nokia 770, so can't be sure if any ARM9E (that's the core used in Nokia 770) specific optimizations are also good for Zaurus. So people who are able to compile MPlayer from sources and test it on zaurus are welcome in this thread. One of the examples is the new armv5te optimized idct in MPlayer 1.0rc1, can anybody benchmark it on Zaurus?

Also this is not quite ARM architecture related, but libmad based decoder in MPlayer seems to have troubles with variable bitrate audio (it loses sync with video). Some more details can be found here http://lists.mplayerhq.hu/pipermail/mplaye...ust/045017.html and in the followup messages. Any volunteer to investigate this problem?

All in all, ffmpeg optimizations for ARM are not nearly as good as for x86, so investing some time in it may provide some performance improvement.
