PeerTube Instance Support Thread

[zalasur]

@cobito Hello, I'm the administrator for the instance over at https://video.zalasur.media/. I noticed an issues playing both live streams and VODs hosted on video.hardlimit.com from my instance. When playing a video, I see a number of CORS errors which is preventing playback. Here's an example URL:

Welcome to Zalasur Media, a PeerTube platform!

Zalasur Media (peertube.zalasur.media)

Here's an example of an error I'm seeing in the console log that appears to be the root cause. I did some quick research and it looks like the culprit might be with hardlimit setting a duplicated wildcard origin ("*") somewhere.

Cross-Origin Request Blocked: The Same Origin Policy disallows reading the remote resource at https://video.hardlimit.com/static/streaming-playlists/hls/6af7997d-447a-42ef-987c-92a171c5c023/a50a90f3-8e68-4341-a09d-8739df36200a-1080-fragmented.mp4. (Reason: CORS header ‘Access-Control-Allow-Origin’ does not match ‘*, *’).

If you want to reach out to me via email my address is dave.finton@gmail.com.

Thanks!

Hi @zalasur, thanks for the heads-up.

A few weeks ago, some Nginx configurations were changed, which seems to have affected video access from other instances.

I'm currently away from home and not sure if I'll be able to fix this from here (I'll be back in a month), but with the information you've provided, I might be able to do something about it.

Regards.

Hello again @zalasur

I've taken a look at the configuration and it should be fixed now. A duplicate header was being sent that affected CORS connections but not web requests.

The videos should now be playable from your instance.

[zalasur]

@cobito I was able to confirm videos are now playable again. I haven't tested live streams yet but I feel confident those are also fixed. I'll let you know if I see any further issues. Thanks for the quick response!

Hi
I started to playing around with the Hardlimit PeerTube Live stream. I was able to setup the live, although after a few seconds of playing the live in private browser window the video stops with the following error

Error The video failed to play, will try to fast forward. 

Is it something known? I did something similar on the other peertube instance and there it works.
Any hint?

[cobito]

@xliiv This is the first time I've heard about this issue. Does it only happen in an incognito window? Does it work in a regular window? What browser are you using?

On my end, I've tried playing live streams in an incognito window quite a few times and have never had any problems.

[xliiv]

@cobito thank you for your quick response

1. both in incognito (as annonymous) and regular window (as logged in user)
2. brave-origin (but i think i also checked it on firefox, anyway i'll do it tomorrow for sure)

[cobito]

@xliiv Okay, no one has reported that specific issue to us. In the past, we've seen connectivity problems when streaming live from certain providers (Germany and Italy), but that was resolved.

Let us know how it goes with Firefox.

[xliiv]

@cobito same broken effect on firefox

does anyone else stream from linux/wayland?

1, my streaming setup is Steam window on linux/wayland - this gets the error (also I've checked streaming some editor window with closed Steam and also broken).
2, i'll also checked other machine, streaming editor window on linux/xorg and it works.

Also between (1) & (2) also OS is differrent.

@xliiv I've streamed quite a bit from Wayland using OBS, always on Fedora or a derivative (Nobara). When live streaming to Peertube from Linux with a Wayland desktop, I ALWAYS recommend the OBS version from Flathub. It's an official build maintained by the developer themselves, and the main plugins are also available on Flathub and are easy to install.

Another important thing is to always choose the h264 codec and avoid using codecs like AV1 or h265, as Peertube does not support any of them.

[xliiv]

@pos_yo @cobito
I can confirm it works with the following changes

1. obs from flatpak (instead from the distribution)
2. use software h.264 (instead of nvenc h.264)

You can change (2)
settings > output > Streaming > video encoder

Thank you for you help and support

UPDATE:
(1) is options, it also works with the distribution version of OBS.

Hi!
For about a couple of days now, the chat on my streaming channel hasn't been working, and I don't see the option to enable it.

[cobito]

@Ransil Hi. It should be fixed by now.

[Ransil]

@cobito Hi! It happened again ^^U

Thanks!!

[cobito]

Hi @Ransil, it should be working again now.
