[Galene] OBS Studio and Galene WHIP

Hello all,

WHIP output got merged into OBS Studio master early this morning.

I tested Galène with OBS master, and it's breathtaking.
Here are the steps I followed for those who want to reproduce:

  1. Clone Galène source code, checkout "whip" branch and rebase on 
master, then run Galène as usual,

  2. Create a Galène group with:

     "presenter": [{}],
     "allow-anonymous": true,
     "codecs": ["vp8", "opus", "h264"]

This is required as OBS streams h264+opus, and by default Galène does 
not include h264,

  3. Build OBS from master,

  4. Open OBS and go to "Settings > Stream" and change:
     - Service: WHIP
     - Server: https://YOUR_LOGIN@galene.example.com/group/YOUR_GROUP/

Unfortunately this setup requires clients to be able to decode h264 and 
sometimes Firefox can have broken h264 depending on distributions.

The latency and quality are really impressive, much much better than 
what Galène-stream could achieve with Gstreamer.

Best,
-- 
Alexandre
