Video disconnects when no movement detected

Problem: After selecting a participant station in a project and switching to liveview, the video streams of screen capture and participant webcam may disconnect. As a result, video and facial expression data will not be available anymore. This is especially observed when NoldusHub is started, but user waits with the starting of stimulus prestentation. 

Source: In version 1.4, video disconnects automatically when no video mutations occur in the participant screen (or in the webcam image). 

Solution:

• start up some dynamic video, or....
• present some other dynamic screen content in the participant screen, or....
• have somebody interact with a window (browser or anything else) in the participant system.
