Thank you for your quick response.
Glad to hear the XvMC support for the newer chipsets was merged. I am
grateful as I have been hoping to see this for quite a while.
Could you offer any insight regarding the state of support for MPEG2
acceleration for video with resolutions greater than 720x576? Am I
correct that this is the current maximum resolution supported?
There is certainly value to the VA API in particular for h.264 and
VC-1 because of Blueray support, but with ATSC the standard is HD
MPEG2, which doesn't have the dependency on applications supporting
the VA API.
