I would like to add, that decoding the same file on intel-media-va-driver-non-free without any crash.

The intel-media-va-driver package without filmgrain kernels included doesn't support AV1 hardware decoding on DG2 and older intel Gen12 GPUs. Users should always use intel-media-va-driver-non-free.

This is very unlucky, thou there is still crash happening on default setups.
What would be correct place to address the crash? ffmpeg or intel-media?

If Intel devs follow this suggestion the crash will be avoided in the "free" version of the media-driver.
