I am trying to communicate two pipelines. The first pipeline is established via Graph Composer and second one via terminal.

Second pipeline is established with the following command

gst-launch-1.0 filesrc location=sample_720p.mp4 ! decodebin ! nvvideoconvert ! 'video/x-raw(memory:NVMM)' ! nvv4l2h264enc ! rtph264pay ! udpsink host=127.0.0.1 port=5000

But on the gxf_server terminal following error has been observed.

Since Graph Composer utilizes nvdsudpsink instead of udpsink, the most straightforward solution would be to generate a new component using GStreamer’s udpsink. However, it is evident from the previous ticket that the component generation tool is currently bugged.

So, Is there a method use UDP protocol in Graph Composer?

Please follow Gst-nvdsudpsrc — DeepStream documentation to make sure the Rivermax SDK works and nvdsudpsrc plugin works in your device before you use it with Graph Composer.

@Fiona.Chen Is Rivermax available for free in both commercial and non-commercial applications.
