When I play an AV1 encoded video clip with vaapi, I got following error in the mpv output:

[ffmpeg/video] libdav1d: Error parsing OBU data
Error while decoding frame!

Full log: https://gist.github.com/runlevel5/403ecaa87dc4bff9e88f6ff35c1fa16e

I am totally unsure if this is a bug or not so I resolve to ask a question instead.

Start with the linked full log and the reported mpv, FFmpeg, libdav1d, Fedora, and Linux versions, then compare the AV1 clip's behavior when played with vaapi. The issue is done when the failure is reproducible and its responsible component or required follow-up is identified.
