[feature request/idea] focus Video/Audio or Media Source mechanism

[lmerkens]

Such a mechanism would allow to reuse buttons or probably more important faders on small media keyboards.

It would need a combination of probably four parts that work in combination

1. An action to Focus/Select a Source (probably limited to Video/Audio/Media - Sources)
2. A possibility to use this focused Video Source in other actions as "Source"
3. An output binding to allow to visualize a focus change
4. A output binding to allow to visualize an error state (e.g. if there is no Video Source in Focus)

Typical Usecases could be:

• a group of midi buttons to control position/size and visibility of a webcam and a group of other midi (radio)buttons to select between multiple connected cameras.
• the implementation of transport controls for Video Sources (Hide|Show Restart | Play/Stop | A fader as Scrub etc.) again in combination with a group of radio buttons to select the video source. (If only one video has to be shown at a time, the latter can now be emulated by reusing a Video source and exchanging the loaded Video by manipulating the "Custom Source Settings"

just an idea ...
