How to get RTPSession from rtpbin

[kingle-zhuang]

public class RTPSession extends GstObject { protected RTPSession(Initializer init) { super(init); } protected RTPSession(Handle handle, boolean needRef) { super(handle, needRef); } } RTPSession session = this.rtpbin.emit(RTPSession.class, "get-internal-session", 1); session.connect(name, RTCP_LISTENER.class, listener, new GstAPI.GstCallback() { @SuppressWarnings("unused") public void callback(Element element, Buffer buffer, boolean early, GPointer data) { listener.handle(element, buffer, early, data); } }); for session still return null how to register class & how to get RTPSession instance

My purpose is like this, we use rtpbin for audio stream forwarding, we use rtp & rtcp src for data receiving, and then send the decoded data through udp sink, we want to detect whether the received rtp or rtcp is stuck, if stuck we need to timeout, I found that RTPSession in rtpbin has on-receiving-rtcp callback, need to register, so we wrote our own RTPSession directly inherited GstObject, and then get the session from rtpbin , but always get null!

It would be better if the good plugin could be ported by the java bridge, the library is excellent, and I hope to continue to improve it!
