> Double-checked: Twitch does say transcoding is "as available" for non-partners

It's mainly done for non-partnered channels with high view count (at latest after requesting it manually).

If they had it on smaller streams, there also seems to be some mechanism that kicks in when a stream restarts multiple times (my guess would be some heuristic thinks there might be problems and tries to be helpful).

Also, like you said, enabling transcoding needs a stream restart right now. Guess this could be improved.

Maybe the system's heuristic just doesn't really remember sessions after some hours have passed so it needs to see a high view count again before turning on transcoding (after the restart).
