We are settling with OvenMediaEngine as they are adding support for capturing video stream from within the browser. Actual streaming features will be appearing in UNA 13.

One big challenge is the infrastructure - we now have experience working with UNA installation streaming to about 5000 simultaneous viewers, and found that server costs for the web server, DB server and streaming infrastructure can be really high when The stream is on, but most of the time it sits idle, so it’s a kind of feature that leads to a very irregular usage patterns. Smaller communities may not have that problem because of low activity, larger communities can spread the load and perhaps absorb the cost, but mid-size networks really struggle - especially those in 20K to 200K members size. A few ideas on how to solve this include launching our own streaming server service and making UNA easer to deploy within scaleable containers.
