Is the Atmel AVR32 able to do video decoding, and at what resolutions?

[TechnoidWIP]

Playing encoded videos requires more bandwidth than just showing pictures.

Data into RAM -> Data + Previous frame out of RAM -> Frame into RAM -> Frame onto LCD

Maximum 30% of the memory bandwidth should be used for video. (Depending on the file format.)

X-res * Y-res * bpp/8 * fps = bytes per second.

MPEG4 uses much more processing power than MPEG2. MPEG4 decoding at 30 fps on a QVGA/CIF screen runs smoothly while MPEG2 can be run on VGA resolution.
