There are extensions to XvMC however, for Via and other chipsets that
allow at least MPEG2 streams to be sent to the GPU for higher level hardware
decode. XvMC isn't really suited to this though, hence the newer schemes.
Actually Intel developers, is there any news of providing hardware H264/MPEG2
decoding via an API for Linux on the G45 graphics chipset ?
