Detect webrtc b frames

[naanlizard]

Is it possible to detect if webrtc will play smoothly using the player only? Or would that require some sort of backend work with OME?

It would be nice to be able to auto detect the best available playback option of (llhls, hls, and webrtc) and use that. It's a project we're hoping to work on and perhaps push upstream if possible

with llhls and hls, b-frames is always supported. When using webrtc, b-frame playback is never supported. I don't think this needs any extra "detection". Reason for that are the limited low-latency decoders of WebBrowsers and the b-frames timing information which OME doesn't "correct"/adjust.

I'm not sure I follow

We have arbitrary incoming streams from users, with or without b frames. llhls will of course always play assuming no dropped/skipped/missed frames in OBS. webrtc may or may not play based on the streamer's settings, and those that haven't configured their stream properly sending b frames.

We can write something to detect whether webrtc will play smoothly in the backend, but a frontend solution may be cleaner, hence the question
