Cloudflare Stream SRT

[yasyf]

Hey! Will write up a proper report tomorrow but wanted to quickly note that SRT ingest URLs provided by Cloudflare Stream result in a connect-disconnect loop ad infinitum.

Update: with other apps, switching from HEVC to H264 fixes the issue. With moblin however, the server kills the connection each time. I'm guessing there's something being sent that CF doesn't like. Logs attached.

What is the URL?

[yasyf]

@eerimoq srt://live.cloudflare.com:778?passphrase=xxx&streamid=xxx, I can give you an example one if helpful

[yasyf]

emailed one to you

[eerimoq]

I've never tested with a passphrase. Maybe that is the problem.

[QayyoomArieff]

I can confirm that using SRT with a passphrase results in very choppy and unwatchable video. When I remove the passphrase, the video becomes clear and viewable

[thexeos]

I can also confirm that connection can't be established when using the passphrase and that Cloudflare SRT endpoint won't connect without the passphrase.

[eerimoq]

I’m not looking into this right now, sorry
