Nice. I had the same idea and now I see it done without lifting a finger.
I could not make it work to watch a session from my vscode in steamos (it could be misconfiguration from my part), so I don't know if you can alter the speed of the reproduction from there, which would be great.
From my inexistent list of improvements, make it so that 2 video sources can be sent simultaneously, one for the speaker, another for a presentation video. That way you can see the person doing the course, while seeing the important bits, and see the code.
