--- Comment #1 from Michael Catanzaro <mcatanzaro at gnome.org> ---
gstreamer-vaapi is intentionally blocked because it doesn't work reliably, see bug #240664 and especially bug #197752 for justification for blocking it.

The future solution is the new va element of gstreamer-plugins-bad. See https://blogs.igalia.com/vjaquez/2020/07/10/new-va-api-h-264-decoder-in-gst-plugins-bad/ and https://blogs.igalia.com/vjaquez/2021/12/08/gstva-in-gstreamer-1-20/. Currently that's still disabled by default, but there is some environment variable you can use to uprank it. Hopefully it will become enabled by default soon (maybe in gst 1.24?) because you really shouldn't need to do anything to get hardware decoding. Anyway, copying from that second blog post:


Maybe that will work?
