Can you describe your test setup(s) a bit more? I had a go at testing this with VAAPI. With the i965 driver on Skylake GT2, fate-vc1_sa10091 fails cleanly without the patch, but gives a GPU hang with it. With the mesa driver on Polaris 11, fate-vc1_sa10091 passes without the patch, but fails with it. I haven't really looked at VC-1 decode much before, so I'm not sure which of these tests should pass. Still, the GPU hang is certainly bad (and possibly the fault of the driver, but it would be helpful to be sure of that if we want to apply this sort of change). More detailed results below.
