[Galene] Examples for one to many distribution?

[Galene] Examples for one to many distribution?

[Stefan Bethke]

Hi, new user and subscriber here,

I'm trying to create a setup where I feed audio into an SFU, and people can connect to the SFU and listen to the audio. Obviously, Galène can do that, but I would like to:
* have a minimal user interface, where users simply choose the group they would like to listen to
* only have audio playing, no video
* disable all other features like chat

I've tried to find information in the documentation, but I didn't immediately see (for example) which permissions exist and if they would allow me to configure a group like that. Are there examples that I could base a custom frontend on, apart from the minimal client?

I'm happy to customize Go and JS/TS code, or even write something from scratch, but I would be really happy to customize something existing.


Regards,
Stefan

Where does the audio come from?

I think the current client can do that

  1. set the "public" flag on your groups to true, this will cause the
     groups to appear on the landing page;

  2. only send audio to the group, this way no video will be played;

  3. give your users the "observe" permission, so they cannot open new
     streams or add messages to the chat:

    "users": {
        "bob": {
            "password": ...,
            "permissions": "observe",
        }
    }

The minimal client should be a good starting point, at least that's what
I wrote it for.  Please let me know if there's anything that's not clear.

I suggest you start with the full client configured as above, and then
we can think together about what further changes are required.

I'm building a custom pion client to send audio from a multi-channel USB audio interface.

Excellent, I will give that a try and will report back.

Will do!

I see.  You may either use WHIP for pushing the audio into Galene, or else
crib the code in galene-stt to use the native protocol.

Please report back with your results.

If you want a quick hack to test WHIP out  there’s a WHIP simple source here:

https://github.com/pipe/whipi/

It says it is for the raspberry pi - but the pi specific stuff is only the video encoder, the audio should work on any linux/unix.

If you remove 
https://github.com/pipe/whipi/blob/a0c30db9b0ff8b10a85f7f3a49854b2312ec6ae1/src/main/java/pe/pi/whipi/Whipi.java#L80

It should just send audio from the default alsa device.
