Test with Janus 1.x

[fancycode]

There seem to be problems when running against Janux 1.x, see #279.

[fancycode]

Not a problem with 1.x according to #279, still should be tested though.

I just tested nextcloud-spreed-signaling on a newly installed Debian system (Bullseye) with janus version 1.x (actually 1.0.1-1~bpo11+1 from the bullseye-backports) and it seems to work just fine.

I've been using 1.x versions of Janus for some time and I can confirm that is working as with 0.x versions.
I'm using this docker to run Janus: mwalbeck/janus-gateway. It is always updated to the last Meetecho version.

Hi, I've just fallen into a problem related with Talk for Android. Since then (version 15.1.1 and beyond) there were no video calls when using signaling server.
Yesterday I took the time to try to debug the problem and I found that it was a Janus version problem.
Since version 1.x Janus supports multi stream peer connections and it works with some differences than the 0.x versions that are still maintained in parallel.
The problem is described on this issue meetecho/janus-gateway#2566
Nextcloud Talk expects that the data channel to receive control messages from is labeled "JanusDataChannel", but in the multistream version they must include the participant ID in the label in order to identify who the data comes from.
So, with the multistream version the data channel is not JanusDataChannel anymore causing that Talk complains about receiving "Unknown message from 1 datachannel". The "1" is the label of the data channel and is not a known label to Talk.
Now that I've tested with a Janus version 0.x I can confirm that there are no more Unknown Messages received and Talk Android works again.

Hi,
I've just setup the signaling server for our NC instance.
Janus 0.x don't seem to be anymore in the debian's repos.
Is it any news about the issue ? Or any workaround on debian-based distro ?

Thank you

Looks like no changes are necessary to support Janus 1.x in the signaling server itself.

See the following Talk-related issues for changes necessary in clients using the signaling server / Janus:

• Web: Janus 1.x compatibility problem nextcloud/spreed#10003
• Android: No video on call after update on v15.1.1 nextcloud/talk-android#2704
• iOS: Add compatibility for janus 1.x nextcloud/talk-ios#1557

Hello,

Did you test a video call from android to android ?

[mircokam]

I tested now android to android and at first, the camera streams aren't transmitted between the android devices (they are transmitted on/to iOS and in/to the Web). To transmit them, you have to disable and reenable the camera on both android devices in the video call. After that it works fine. I also found your issue describing the problem.

Ok... I was wondering if the upgrade of HPB would solve that issue, but it is not the case... thank you

All these issues are purely client side, see #280 (comment) for the PRs in the client apps to support Janux 1.x. If you still experience (other) problems, please open a new issue in the related app repository.

Hi @fancycode.

If you still experience (other) problems, please open a new issue in the related app repository.

There is an already opened issue for the referenced problem in the proper repository.

Thank you and cheers
