automated black detection

[markvdb]

Ffmpeg has a blackdetect filter

• Can we detect problematic cameras automaticly?
• We don't want this to die when the camera stream dies. Can we connect this to the (unencoded) voctomix single stream?
• Where do we throw the relevant output?

Voctomix survives a dead camera, but bmd-streamer doesn't.

If we're looking into having enough redundancy, maybe we should have the audio also in the presenter stream and switch to only that while the camera is being fixed. We need to check how does voctomix change audio streams, but should be doable.

In this case we lose the output from the speaker's laptop (which is an issue mostly for multimedia-oriented dev rooms), and need to find how to pass the sound also to the presenter box.

Might or might not be useful to detect ingestion instability with the new MS2131 ingestion devices.
