First of all, Thank you and congratulation to all who have been working on  
this project. This is great.

I am using Lynckia in a prototype as a 1-to-many broadcasting solution and  
I would like to cover non-webrtc enabled browsers.

I have been reading the code of the Lynckia project for a few days now and  
it seems to me that it would be possible to extend Erizio’s codebase with  
h264 and/or Thoera transcoding by adding a externalOutput.  
This would allow broadcasting to tags for browsers without webrtc  
capabilities.

My first idea would be to forward the stream to an icecast2 server or serve  
the stream directly from an url offered by the app running the ErizioAPI.

Could anybody on the group confirm if it is indeed feasable ? What is also  
unclear to me is the amount of effort needed ( I havent done c++ for a  
while now ).

Is such a feature already included in the roadmap ? If not, would this be a  
good candidate ?

Regards.

Y.

Hi Yannick,  
Did you manage to forward the stream from Erizio to anything else  
(icecast2, ffmpeg, etc)?
