Thanks for your interest!

It's been difficult to find an easy example for sending video. Mostly because colorspace conversion, chroma subsampling and planar packing of the various video formats is a very very deep rabbit hole (not to mention CPU-intensive for python/cython)

A while back I was working on some examples using ffmpeg since it already has very efficient pixel format conversion. Here's a gist with a sender and a player, both with click cli's.

Note though, that it's using pipes to get the raw data from/to ffmpeg, so it'll only work in Linux and macOS (which is why I never added it to this repository)
