I had an old HP 5:4 monitor and a Jetson Nano 2Gb which were not used for anything. So I decided to turn them into permanent "funny puppies" TV in my living room.

Unfortunately Jetson comes with a really old Ubuntu image from Nvidia, so I wasn't able to run modern yt-dlp and mpv in it. I had to pack everything inside Docker.

This is the result.

In practice I bumped into errors about DRI and DRM devices not available to mpv from inside Docker, and inability to access X11 display from within the container.

Even after solving most of the issues, I got mpv running and displaying a window buffer, but no video got drawn (instead GUI just stuck while mpv was running in the container).

I decided to call it quits and ended up running screenhappy.io on Chromium instead of puppies videos.

I did learn a couple of new things though:

• Unofficial YT API: api_url="https://yt.lemnoslife.com/search?part=snippet&maxResults=25&q=funny+puppies&type=video"
• How to set up python venv inside Docker container (see Dockerfile)

Run the following command in the directory containing your Dockerfile and script:

docker build -t yt-video-player .

Running the container can be tricky due to the need for X11 display for mpv. If you're running on a Linux host and want to try displaying the GUI, you can pass the X11 display socket and environment variable like this:

./run.sh
