Is it possible to stream to Twilio Video API from desktop applications like XSplit broadcaster or OBS (via RTMP or RTP protocols)?

Twilio Video uses WebRTC, so you would need to convert your RTMP or RTP stream into WebRTC somehow. I'm afraid that's all I know though. There's some interesting articles online about that conversion but not covering Twilio Video. It's probably a good start though.
