as such I was wondering if there is a trick to make this work

It works in OBS because we configure encoders outside of webrtc entirely

exactly

because it is a different protocol. rtmp/srt -> hls/dash, you can think of it as you putting in water from one side into a bucket, wait for the bucket to fill up, then drain the bucket

webrtc is just straight up pipe to pipe, end to end, no buffering with the bucket

I am always talking about WHIP

so either you 1) have the encoder outputs the keyframe at a defined interval (in the case of OBS)

or 2) the encoder responds to the peer saying "hey i need a keyframe" (in the case of browser)

it sounds like you want an option to configure WHIP so that we ask you for a keyframe (interval)?

Oh I see, so as far as you know there is no way to do the same on the browser and require a GOP size from chrome. Is there a chance you include this as a POST API option on the negotiation process on your side?

that's not part of the WHIP spec, but we can potentially configure it on the input ID

That would be lovely

e.g. for this input ID, please ask me for keyframe every 2 seconds because i'm using a browser

e.g. for this other input ID, please never ask me for keyframe because i use OBS

like that?

That sounds exactly that

we were also discussing the possibility of allowing the customer to request keyframe over HTTP because recording

Mostly to support browsers and lower the reconnection time etc

That will also work

i don't know if reconnection is the correct term

more like recovery

While you are here if I may ask, do you have any news of when we can have live viewers analytics?

we do have https://developers.cloudflare.com/stream/getting-analytics/live-viewer-count/

were you looking for something else?

oh sorry I am referring to WHEP

we are still working out (many) of the quirks and kinks with WHIP/WHEP + Calls

analytics is low on the priority

before going GA we also need to make it work with HLS/Dash

plenty of things on the roadmap

I see. Indeed WebRTC is a very difficult protocol to master especially on a global scale 🙂 It is amazing you have come so far. Great job BTW
