Owner

We're sometimes abusing the internal RTMP failover of a multi-node origin-edge SRS cluster to "switch" between two sources without interrupting the RTMP session. It kind of works, but is peak jank.

Ideally, we want to have a very simple headless switcher which is able to take n inputs, and seamlessly switch between those through remote signals (e.g. websocket/http).

One possible implementation here could be https://github.com/ffplayout/ffplayout, which seems to support the required functions for this.

Another possible implementation would be to build this on top of Gstreamer, wrapped in Python.

Should be resilient against sources going offline repeatedly or have package loss
Should allow switching between sources without interrupting the outgoing stream
Should provide a lowlatency multiview in Webbrowser (e.g. webRTC), with simple controls
Should provide controls via simple HTTP API to allow scripting
