Is it regression? Good in old configuration?

No, this issue exist a long time

What happened?

On Linux machine BMG, running a specific case in ffmpeg-libvpl or gst-libvpl causes a system crash. The same case runs successfully with ffmpeg-vaapi and gst-va.

cmd:
ffmpeg -v verbose -hwaccel qsv -init_hw_device qsv=qsv,child_device=/dev/dri/renderD128 -hwaccel_output_format nv12 -hwaccel_flags allow_profile_mismatch -c:v hevc_qsv -i input.bin -lavfi 'null' -c:v rawvideo -pix_fmt yuv420p -fps_mode passthrough -noautoscale -vframes 8 -y -f tee '[f=md5]pipe:1'
