I have been working with hardware acceleration in the Zonemnider docker and have run into an issue. I have the ffmpeg option '-hwaccel auto' set and have not had any problems. When I try to add the vaapi hardware acceleration to the cameras the docker will run for many hours up to a day and then the host server locks up and can only be hard reset.
When I check in the docker, the vaapi acceleration is available in ffmpeg and I see the /dev/dri device in the docker. Zoneminder knows that I have an Intel GPU in the host. I believe this is supported by Qemu and libvirt.
Why can't I enable hardware on the cameras without crashing the host? Could this be a docker (qemu) issue?
