For android tv I cannot recommend Smarttube enough. https://github.com/yuliskov/SmartTube

Instead of using a sort of Docker Hub proxy, you can also use GitHub’s repository or Quay. If the project allows it, you can easily switch to these alternatives. Alternatively, you can build the Docker image yourself from the source. It’s usually not a difficult process, as most of it is automated. Or what I personally would probably do is just update the image a day later if I hit the limit.

An Anki deck would probably be far more useful.
