Created attachment 164302 [details] [review] add controlable properties Did not wanted to push this before freeze. The attached patch makes some v4l2 properties controllable. Main issue is the timing of the parameter changes. Right now I run an own timestamp counter because - v4l2src is a live source and thus timestamps are unpredictable - if we ask for 3 frames in the 'programm' we want 3 frames even if there is one bad frame in between I did not added property probe interface. If a camera does not have this setting/getting them will be ignored.
