Licode is an open source webrtc platform available at [url removed, login to view] and [url removed, login to view]
Currently it lacks the support of H264 codec and V9 codec in MCU mode. In P2P it works fine.
I don't think it is a big issue since it should not be transcoded to another codec just forwarded to the other participants. Currently VP8 is used.
I need an update of the original code to support VP9 and H264 by Licode MCU.
