This is crashing within the call to vaInitialize. In searching on this topic, it appears that libva doesn't mix well with Wayland. This is likely just one of the problems you will encounter with the Wayland compositor and why it still fails to be a replacement.

My guess is that you found the issue I've reported that was simply the result of intel lagging on performing a release. Also, mpv with libva works perfectly on my system.

This is likely just one of the problems you will encounter with the Wayland compositor and why it still fails to be a replacement.

Well, that's news to those of us that have been using it full-time for year(s).

Anyway, thanks, I'll look into this more on my own.

Another thing to consider is using an older Qt. Your logs suggest Qt v5.12.6 is being used. We build against an older Qt and have not updated/tested against that specific version.
