Transcoder Campaign: Captain Stronk

Update to the Stronk Broadcaster project


A few weeks ago the Stronk Broadcaster experiment was established. A CDN powered by MistServer combined with Livepeer nodes to enable low latency livestreaming from the browser

Powered by the broadcast-in-browser component of StreamCrafter, a new project from the OptiMist Video team (the maintainers of MistServer), you can now visit a prototype to ‘craft’ livestreams from the browser

Disclaimer: This is a very early release, so expect some unfinished UI elements or instability. The supporting infrastructure is rolled out on a small scale and can only support a small load of streams and viewers
Note that switching to another tab during a broadcast can cause the browser to pause the broadcast to save resources
