And doing things like tuning to a specific channel really is something the app should take care of. This is intended as a soundcard mixer like application. and yes I'm aware of all the issues with sound card mixers and their gazillion settings. But in this case it is a bit different: For uvc cams there is a well defined and limited set of controls. For proprietary cams, we usually have direct access to sensor registers and could go completely crazy with the amount of controls, the trick here is to hold back with controls at the driver level, not to dumb driver export controls down, like we are doing in the soundcard case.
