I have been streaming from RPi/ffmpeg to YT for a few years now, and the streams stop from time to time for reasons I never quite figured out. The best I could do was put a watchdog timer on it and the restart the stream when it failed.

Then Google changed the APIs and I could no longer restart the stream ingestion programmatically, even though I could restart the stream from the ffmpeg side. 

So I am very curious to see what you can figure out.
