Details

AMD is planning on making sure the InputSampleFreq field of DXVA2_VideoDesc is read and included into the decision whether to allow the decoder to be created.

We need to ensure that we're specifying this correctly so that we don't get decoders created that would require throughput that isn't available.

We'll also need to detect the driver version in which this functionality is available, and skip our hardcoded list of blacklisted device ids.
Priority: -- → P2
Component: Audio/Video → Audio/Video: Playback
Mass change P2 -> P3
Priority: P2 → P3
There's a problem with that approach. This assumes that the framerate is constant. And from a few files I'm working on right now, this isn't true.

In particular videos coming from live streams.

I guess the framerate will be low enough that it doesn't really matter anyway.
