Display server if rendering to display(X or wayland):
no rendering.
Issue behavior
Describe the current behavior
I experience intermitent segfaults when encoding MPEG2 content to H264 with ffmpeg. Generally, if I restart the process, it finishes OK (maybe happens 10-25% of the time, so not insignificant).
Sadly, it seems ubuntu doesn't have "debug" versions of the module, so this might not be the best place for the bug, but reporting it just in case.

cmd line: ffmpeg -init_hw_device qsv=hw -filter_hw_device hw -i test.ts -map 0 -c:v h264_qsv -global_quality 28 -profile:v high -preset veryslow -c:a copy -c:s copy test.mkv
kernel logs show that its segfaulting at the same address each time
examples:
I'd note that 2f9000 doesn't seem to be an instruction in it, per obj
Describe the expected behavior
not segfault
Debug information
deb version: Version: 22.3.0-1
ls /dev/dri
?dmesg >dmesg.log 2>&1
?vainfo -a >vainfo.log 2>&1
?strace YOUR_CMD >strace.log 2>&1
?export LIBVA_TRACE=/tmp/libva_trace.log
first then execute the case.
