from this topic, Gstreamer need to use udpsrc to receive rtp stream. currently deepstream-app does not support using updsrc to receive rtp stream. Here are two solutions.
- deepstream-app is opensource. you can modify create_multi_source_bin of \opt\nvidia\deepstream\deepstream-7.1\sources\apps\apps-common\src\deepstream_source_bin.c to add support for updsrc.
- you can set up a rtsp source instead of rtp source. then update[source0] by setting type=4 and url=rtsp://xxx.
