I don't have access to our Cloudflare admin tools so I can only evaluate the quality / stability of the HLS stream it outputs.

Can someone share more details about these fields in the stream video file JSON?

"publicDetails": {
      "title": "",
      "share_link": "",
      "channel_link": "",
      "logo": ""
    }

I wonder what's their purpose and how can they be "set" ?

Doing more testing with Cloudflare live streams today, still not looking good. I set up a personal Cloudflare account to have a better view for testing, even in the Cloudflare dashboard the stream is freezing frequently.

What's the encoder config? And are you using srt or rtmp

Using RTMP.

What software are you using to stream? What's the encoder config for the stream?

Can you DM me the video UID of the livestreamed video?

Streaming via OBS.

@MRS do you have freezing at the beginning or somewhere in the middle?

In the middle / throughout.

Getting maybe 1 minute or stable video at a time.

@MRS could you try with keyframe interval set to 4s and try again?

Ok I’ll try that now.

while you are trying 4s

much appreciated if you can capture an HAR as well and DM me the capture

Started off shaky, but now with the 4s keyframe intervals it seems stable, haven't seen it freeze.

And right as I say that >_<

Dynamic GOP streaming is generally highly discouraged

Especially for HLS streaming

A 2 second keyframe interval should work well

@tt2468 While we are on this subject do you know how to force 1-2sec GOP within the SDP for WHIP?

I only know how to do that in OBS

I know next to nothing about browser webrtc stuff

🙂 thanks man

Indeed in OBS this is working thus I was trying to figure out if this is possible in the browser. OBS Whip plugin source code doesn't do anything special on this matter and as such I believe it is a more internal thing.

@Protogon browser responds to PLI from the peer to send a keyframe, in the cloudflare context the peer would be us. By default if the viewer requests PLI, they will be forwarded to the publisher (throttled). As a fallback, we also send PLI every 5 seconds independent of forwarding

Thank you @Rachel but this is working when setup in obs and can keep it at 30frames 1sec GOP. On the browser (Chrome atm) there is no way with getUserMedia to send an offer SDP requesting GOP of ie. 30 frames
