Please add MPEG-4 AVC part 10 (h.264) XvMC acceleration.
XvMC API seems to be supporting MPEG-4 by using: avcXvMC.h
Here in Poland the MPEG-4 AVC part 10 (h.264) was chosen for digital TV DVB-T transmissions. Having all this decoding on Geforce would improve quality and performance during watching. I know this mpeg-4 decoding is available in Windows. So please port it to Linux. Other countries are also going to use MPEG-4 AVC part 10 (h.264) for DVB-T so this standard is going to be globally omnipresent.
MPEG-4 AVC part 10 (h.264) DVB-T broadcasting is on air in Poland now.
