Not sure they have an Orange Pi kernel, so probably won’t use it on the Orange Pi 5.
Does hardware transcoding work on the Pi with Void Linux? Channels DVR is probably better with that.
If I get unlazy, I can switch to that on the Pi, on a day the Channels DVR isn’t recording anything.
Another interesting Linux distro is NixOS, sounds like you can downgrade any package, without doing anything to anything else. Like downgrading everything it depends on. So it probably uses more space.
You might be able to download the Orange Pi kernel, and replace the ARM Void Linux kernel with it.
