Video starts lagging after some time

[SilverLive]

Hi, after a while of beeing connected to my video sender (HoloLens), the the video receiver, displays the stream really laggy which means it displays one frame every 6-10 seconds. Where can this result from? Any ideas?
Maybe the following information also helps:
The sender generates the stream via MRC and the receiver has 3 VideoSources which can send data but currently are not connected to my image-creator.

Thanks in advance.
