I'm quite new to gstreamer and I need some help.
I've created a working pipeline for RTP Multicast on iMX6. I launch the pipeline with gst-launch -v. I can get the sprop-parameter-sets, and put it in my SDP file on the client side (a Linux PC).
Now my pipeline is in C code, and I don't know how to retrieve the sprop-parameter-sets property from the rtph264pay element.
I tried with g_object_get, but it gives me a NULL value. I also tried with gst_element_add_property_notify_watch but my code won't compile (implicit declaration of this function)
