A future proof, experimental WebRTC VP9 SVC SFU


Medooze SFU

A future proof, experimental WebRTC VP9 SVC SFU.


There are already several good production ready alternatives for implementing multiconferencing on webrtc, like Jitsi, Janus or SwitchRTC SFUs and even if you need more legacy support you can try our MCU. Our goal is to experiment and provide an early access to the functionalities that will be available in the near future that will improve drastically the performance and quality of multiconferencing services on WebRTC.

Due to the experimental nature of this functionalities we will only officially support Chrome Canary to be able to access the very latest functionalities available (sometimes even running behind a flag). We don't care about interporeability with other browsers (they will eventually catch up) nor SDP legacy support.


It is our goal to implement only the We intent to implement support the following features:

This is a moving target as new functionalities will be available on Chrome and some others will be removed, we will update our targets appropiatelly.

To enable Flex FEC and VP9 SVC on Chrome Canary you must use the following command line:

chrome.exe --force-fieldtrials=WebRTC-SupportVP9SVC/EnabledByFlag2SL3TL/WebRTC-FlexFEC-03/Enabled

SFU Media Server

The media server code has been moved to : https://github.com/medooze/media-server

cd /usr/local/src
git clone https://github.com/cisco/libsrtp
wget http://downloads.sourceforge.net/project/xmlrpc-c/Xmlrpc-c%20Super%20Stable/1.16.35/xmlrpc-c-1.16.35.tgz
tar xvzf xmlrpc-c-1.16.35.tgz

# Compiling XMLRPC-C
cd /usr/local/src/xmlrpc-c-1.16.35
make install
cd ..

# Compiling libsrtp
cd /usr/local/src/libsrtp
make install

# Compiling SFU Media Server
cd /usr/local/src/media-server
make sfu


In order to run the SFU you need to configure in the SFU controller the location and properties of the SFU Media Server, this is done in the `sfu.conf:

# Set the media server xmlrpc endpoint url 
mixer.url = http://localhost:8080
# Set the media server IP address
mixer.ip =
# Set the media server public IP address (i.e. the one facing the clients and which will be used on the SDP)
mixer.publicIp =
# Private subnet, in case you want to test it on a private network
mixer.subnet =
# Websocket server URL
server.port = 8084

Currently the server does not support WSS transport, and while it could be supported, it is preffered to run it behind an nginx server which can server the HTML client and proxy the WSS request to the server internally:

# Add to your server section of the nginx configuration
    location /sfu {
                proxy_pass http://localhost:8084;
                proxy_http_version 1.1;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 3600;
                proxy_set_header        X-Real-IP       $remote_addr;
                proxy_set_header        Host            $host;
                proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
                error_log  /var/log/nginx/sfu.log info;
