Have you considered vp8? It may sound weird but this is basically what vp8
was great at: being really simple to decode.

Hi,
If you were to design a video codec for a very low-end decoder, what
would it look like?
My target is MIPS 100MHz, and it should decode 320x240x30 in full speed
in software, with headroom for audio too. Seems all the codec research
in last 20 years has been more quality with more overhead, no
15 matches
