[Bug]: Mpv crash when using intel vaapi hwdec #1983
Description
Which component impacted?
Decode
Is it regression? Good in old configuration?
None
What happened?
Launching a video in mpv with hwdec=auto-safe(in my case) leads to rare random segfaults with no particular pattern i noticed. I don't know if it's a regression or not since i only recently bough this GPU. Since crash is rare and i don't launch every video i watch with "export LIBVA_TRACE=/tmp/libva_trace.log mpv" i can't provide that log. I hope what i provided is enough to fix it.
What's the usage scenario when you are seeing the problem?
Playback
What impacted?
Regular playback of videos using hardware decoding e.g. mpv.
