How to Run a 24/7 YouTube Live Stream From Prerecorded Video Without OBS
To run a 24/7 YouTube LIVE stream without OBS, upload a finished video (or several) to a cloud streaming service, paste the RTMP URL and stream key from YouTube Studio, turn on looping and start the stream. The encoding runs on the provider's servers, so your computer and home internet can be off. Plan for YouTube's rules: streams longer than 12 hours may not be archived as a replay.
