 Streaming RTP 

 

Once you have UDP streaming, it is relatively simple to change to RTP streaming. One parameter 
change is needed. To stream using RTP, complete the following steps: 

 

(21)

 

In the CH1 configuration tab, click on “stop” to stop the current encoding session. 

 

(22)

 

Change “Output Format” from “UDP” to “RTP/RTSP”. 

 

(23)

 

Click on “start” to start the RTP encoding session. At this point your settings should look like the 

following:
