Live Streaming broken since 3.4

[normen]

Describe the current behavior
When trying to stream to a persistent live stream using OBS the stream never goes live on the web page. It used to work in previous versions. Now theres no .m3u8 file created in the stream folder and theres only one .ts file which grows ever larger in size (hundreds of megabytes in 0-000000.ts).

Edit: When stopping the streaming in OBS a m3u8 file is created but by then the stream isn't available through the web page anymore either (for obvious reasons, it actually ended).

Steps to reproduce:

1. Create permanent live stream
2. Stream to server using e.g. OBS
3. See that the stream never starts and no playlist file is created

Describe the expected behavior
The stream should be playable in the web browser.

Hello,

Please try to enable transcoding or set OBS output keyframe interval to 2s

[normen]

Hi, thanks for the quick reply!

When transcoding the video I get a working stream again but my server CPU can't handle that at all, even if I don't set any resolutions to be transcoded to (like I do in the main video settings as well - I don't want multi-resolution). Setting a keyframe interval of 2 seconds also results in a working stream but it taxes the streaming computer quite a bit more.

So first of all thanks for the quick-fix but maybe theres a chance it could be made working without a keyframe interval again?

Thanks for this project,
Normen

What are you streaming? A video? An audio file? Your desktop screen?

[highvoltage]

I have the same problem, it's easy to reproduce on https://peertube.debian.social (you'll just need to create an account on debian's gitlab instance in order to log on, or I could manually create a temporay user if you want).

From OBS it seems to work just fine, and in the peertube logs it appears to be remuxing and when I end the stream from OBS it seems to close with no error logged. Although on the PeerTube side it just says waiting for the stream to start. Setting the keyframe interval to 2 doesn't seem to make any difference in my case. Any pointers for me or info I can get for you?

What are you streaming? A video? An audio file? Your desktop screen?

Various things. Mostly video. Mainly a stage. Sometimes a "vlog face" and desktop.

[Chocobozzz]

I'm sorry but I can't reproduce. What OBS version do you use? Could you screen its options?

[normen]

They are the default "simple" options, 2MBit bitrate. I notice however that this might be limited to MacOS, it seems that my Windows PC (with Nvidia GPU) streams just fine with the "simple" settings, without keyframe setting.

Hi team,
today I created a live stream and fed it with OBS data.
I did not face ANY problems.

System
peertube 3.4.1
OBS 25.0.8
both running on Linux
no docker

[highvoltage]

Thanks for all the feedback, I suspect it might also be firewall related on the host. Will check again over the weekend and provide some more details. Thanks again.

Then I'm closing this issue for now. Don't hesitate to comment if you have new info
