[Mesa-dev] [PATCH] mesa/st: don't advertise NV_vdpau_interop if it doesn't work.

[Christian König]

From: Christian König <christian.koenig at amd.com>

As long as we don't have a workaround for frame based
decoding in VDPAU we should not advertise NV_vdpau_interop.

v2: fix commit message, check if get_video_param is present
