I'm not aware of RTSP pause of the source being included as of yet. The nearest you may get is to set your StreamType in your application to rtp-live, or rtp-live-record. In this situation the source stream starts once a client views it, and it stops a short while after the last client has ended his viewing session. I'm not sure if this fits in with your plans. There may be examples of calls to RTSP sources within the
code section of our tutorials, and so could be extended to implement a pause control.
