2. "How would you do in this situation, to have the video stream in the browser, with as low CPU usage as possible?"

Since it's being consumed on (only) the local machine you've got an excellent situation where you can use any obscure codec you like, as long as the browser you're using supports it. Also you don't need to care at all about network bandwidth. If minimising CPU usage is the #1 priority then something fairly lightweight like mjpeg might do the trick. Alternatively you might get away with not compressing the video at all (but this might cause issues due to dealing with huge amounts of data). If I wanted to minimise CPU usage, I wouldn't be doing it in python.
