I want to insert metadata in RTSP streaming specifically in RTSP server. How exactly I can do that? My gstreamer pipeline is
"v4l2src device=/dev/video3 ! videoconvert ! v4l2h264enc ! rtph264pay name=pay0"
I want to insert a string of user defined data in RTSP stream. I tried an element called taginject but its of no use. I tried passing this pipeline to gst_bin_iterate_all_by_interface() API which returns those elements which support GstTagSetter interface. But none of the elements in my pipeline support GstTagSetter interface. I tried using mux elements but those mux can not be linked to rtph264pay. I can't use any other encoding other than H.264. Please suggest any other methods to insert metadata.
Thanks
