Whenever I hear things like this I’m surprised there’s no set of reference videos & reference decoded frames. Like: “this video file should decode into this uncompressed video. This video file should decode into this other uncompressed video” - etc, with a large combinations of encoder features. Like a video equivalent of the commonmark test suite[1]
I was playing with email parsers a couple of years ago and I still don’t know if my cobbled together email parser works correctly with all emails. 40 years after RFC822 it seems there’s still no standard, reference set of email message test cases to process to verify an email parser is correct & robust.

It's just that they're commercial products e.g. https://www.hhi.fraunhofer.de/en/departments/vca/technologies-and-solutions/h264-avc/h264-bitstream-test-suite.html https://www.hhi.fraunhofer.de/en/departments/vca/technologie... https://www.allegrodvt.com/video-ip-compliance-streams/compliance-streams-validation-verification/h264-avc-elementary-streams/ https://www.allegrodvt.com/video-ip-compliance-streams/compl...
