Comment (by Balling):
>(which I'm surprised about because it's often the hardware decoding that
shows decoding errors
Not really. HW decoder is reference and is bitperfect on NV12 and P010
levels. There are some exceptions, where there are bugs in our parser (and
yes, hevc_cuvid still NEEDS sw parser and bugs in sw parser cause failure
in ffplay -vcodec hevc-cuvid, see #7799). There is like one bug I know
where the bug appears to be in HW Nvidia chip, but then remember there is
a driver there, driver bugs are real too.

And another bug in avc where there is still an issue with HW decoder, that
needs to know the structure #9771
