MPEG-4DS Proof of Concept
Chinese developer abraxas has ported xvidcore mpeg4 decoder lib to devkitpro.
It's still not optimization (slow...) I found some arm asm & arm dsp asm optimization code in mplayer sources libavcodec lib. maybe i will change lib for decoding (xvidcore seem slow).
I think it possible to decode mpeg4 simple 256x192 24fps when best optimization idct & yuv->rgb and others.
The quality seems to be good. felix123 only noticed blockiness in a few scenes. (The readme recommends 256x192, 15fps, low bitrate).
OOPMan noted with optimisations it should be possible to get good performance out of this, possibly even with sound if you use ADPCM for the audio...
