Hello,

sorry, I have no expertize to review the patch. But I have tried it in real
life.

Several wmv3 and vc1 files were decoded fine, but not any h264.
Could you please point me out which h264 files can be decoded by h264_dxva2
(or just give a sample)?
I have tried a lot of files but only get:
[h264_dxva2 @ 0066CA00] Unsupported file

Several vc1 files crash the application. Here is 2-second example:
ffmpeg -ss 0.5 -vcodec vc1_dxva2 -i

Best regards,
