Hi Philip, The issue seems to be from MPV side rather than from ffmpeg patch. I was able to decode the clip Halo_AV1 properly bitmatching with nvcuvid output with ffmpeg + VDPAU.
Please find the cmds I used to verify the same. ./ffmpeg -hwaccel vdpau -i /home/bondamanoj/VideoClips/AV1Clips/Halo_AV1.mp4 -y decoded_vdpau.yuv ./ffmpeg -hwaccel nvdec -i /home/bondamanoj/VideoClips/AV1Clips/Halo_AV1.mp4 decoded_nvcuvid.yuv cmp decoded_vdpau.yuv ~/Downloads/ffmpeg-git2/FFmpeg/decoded_nvcuvid.yuv The same clip is dumped using mpv via cmd ./mpv --hwdec=vdpau-copy --o=Halo_dump_av1.yuv --of=rawvideo /home/bondamanoj/VideoClips/AV1Clips/Halo_AV1.mp4 Is differing and is having corruption while playing.
