related changes were passed. The below commit and its follow up seems to have
caused the issue. I am looking to fix this. Please let us know if you have any

Thanks, patch looks fine to me now.
While testing, I came across some very weird behavior:
The following commandline:
./ffmpeg -hwaccel cuvid -c:v h264_cuvid -i test.mkv -an -sn -c:v h264_nvenc
-preset slow -qp 22 -bf 0 -f null -
Sometimes, it runs into the following error:
[h264_nvenc @ 0x3f7d

Thanks, patch looks fine to me now.
