Blinder sources

The blinder (formerly “stream blanker”) suppresses all live outputs while keeping the mix recording running. Enable it in the [blinder] section:

[blinder]
enabled = true

By default the blinder generates a SMPTE test pattern with silence. Customise it with a [source.blinder] section using any source kind:

[blinder]
enabled = true

[source.blinder]
kind = test
pattern = black
volume = 0.0

Multiple video sources

You can have several selectable video blinder sources (e.g. “break”, “closed”) that share one audio source:

[blinder]
enabled = true
videos = break,closed

[source.blinder]
kind = tcp

[source.break]
kind = tcp

[source.closed]
kind = tcp

The three sources each listen on their own TCP port (assigned sequentially from the blinder port range). voctogui shows a button for each video source so the operator can select which one to display.
