<p class="MsoNormal">Hello.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I am having trouble with my GStreamer pipeline (I believe) stripping SDP information from my stream. I am using an RTSP camera source to stream video through a SoM to be displayed by VLC on a separate computer. When playing the camera source
directly on the display PC I can simply enter the IP address of the camera into VLC and the stream will play. However when streaming through the SoM I require an SDP file to play the stream. I am not sure what is happening, whether data is being lost in the
pipeline or something else is happening. I have analysed the packets leaving the camera source and the packets coming into the display computer from the SoM, and they appear identical to me. Do you have any advice to help fix this issue?<o:p></o:p></p>
