I hope we'll see this evolve around nostr. Kieran is already looking into supporting multi-track streaming on Zapstream. It's a new feature in the latest OBS build but the server needs to support enhanced rtmp.

Great to hear! nostr:npub137c5pd8gmhhe0njtsgwjgunc5xjr2vmzvglkgqs5sjeh972gqqxqjak37w was looking into adding it directly on nostr.build mp4s so that clients like Damus could support it automatically without any code changes somehow
SRT is the better option. Open source supports encryption and dynamically adjusts bit rate. Also supported by OBS.
