under 1% on most devices. I tried running with this idea with FFMPEG
decoders, optimised for neon but have not been able to bring the cpu
usage far down enough. Probably due to my lack of experience with

Seeing how the Android handles m4a like a champ I jumped on that idea
but I guess I'll have to go back to libavcodec decoding and see if I
can't make that work better.

But thanks for chipping in Alex, I'm really impressed by the level of
helpfulness on this list.
