AFAIK, besides theora, everything is HW accelerated.

Re - DSP OC - I did experiments back when I was playing with DSP driver, the result - even if OC to 800MHz, C64x is not powerful enough to decode H264 medium/high profile. At least the examples I had here were still stuttering. And I am not talking about 720p resolutions. The same as on N9/50 with its 800(810?) DSP. The only thing that *may* benefit is recording, i.e. if OC to lets say 650 or 700 MHz, DSP would give stable 25 fps for 720p instead of now varying 23-25fps. But considering the tradeoff ( higher risk to fry the DSP, instability, much higher voltage needed which stresses the other parts too, etc), I considered to not allow anything beyond 600MHz. One of my devices was not able to go beyond 780MHz. So, as of now, I wouldn't change that limit . Feel free to make a patch and pester Pali if you feel he'll be less restrictive than me . Or just get the sourcecode, modify it and fry your device .
