(gdb) According to mos_bufmgr_api.c source code https://sources.debian.org/src/intel-media-driver/22.5.1+dfsg1-1/media_driver/linux/common/os/i915/mos_bufmgr_api.c/?hl=44#L44 we have:
void
mos_bo_wait_rendering(struct mos_linux_bo *bo)
{
bo->bufmgr->bo_wait_rendering(bo);
}So I am not surprised to get a crash if bo is NULL.
I also have the problem if I use Gnome with X11 instead of Xfce. But I do NOT have the problem if I use Gnome with Wayland. It looks like the problem is specific to X11.
I don't know if the problem is specific to Debian or not.
I also do not have the problem if I play the video (using X11) with totem instead of vlc.
The problem is easy to reproduce for me.
You should be able to get a copy of the video on the Internet :-)
