was giving me a bunch of screen tearing. I wanted to just include the upstream Debian apt repos and use apt preferences to select what packages to use. That didnt work out, and I read on the rpi forums that there was some incompatibility between the two distros.
Docker to the rescue.
Kinda. I had to make a bunch of concessions on best practices in order to get it to work. The largest glaring issue being having to run the mpv process inside the Debian container with root perms. If you find a fix to that, let me know. I don’t keep sensitive info on the pi, so, deal with it. Here is my dockerfile and commands for running it. I will strip out some of the stuff specific to my use case. It is a nice multistage Dockerfile. To get sound working with pulse audio, I also included the pulse-client.conf. There may be too many packages added, the line with va-driver on it may not be necessary.
I got it working so I stopped working on it.
