Supporting live streaming like Manim

Manim has a python -m manim --livestream option and even options for Twitch python -m manim --livestream --to-twitch --with-key [streamkey] which allow to write the live rendered content to Twitch in real time.

It would be cool to be able to the same from Javis. This functionality might be better suited for a package on top of Javis. As far as i understand ffmpeg provides that functionality.
