Could you provide this patch? My platform is SandyBridge, maybe I can
make use of it.

>> Tested on CTG & SNB along with VA context created for decoding (mpeg2 or h264),

>> VA context + mpeg2 decoding first, VA context + h264 decoding first }.
>>
>> Another test includes gst-launch videotestsrc ! vaapiconvert direct-rendering=0 ! vaapisink
>> on SNB. vaDeriveImage() needs to be fixed next.
>>
>> Note: this does not allocate tiled surfaces on SNB.
