Please describe the problem:
when I make a connection to a rtsp mpeg4 stream with this [1] pipeline, nothing gets print out.

But when I start this pipeline [2] to another encoder both pipelines pushes data to pipeline. Every data stream is from its own encoder. When I stop the second stream the first stream also stops. This even works if you select a wrong port in the second stream. Then you get only the good data from the first stream but by control of the second stream.

[1] gst-launch rtspsrc location=rtsp://10.3.0.23/mpeg4/1/media.amp ! fakesink dump=1
[2] gst-launch udpsrc multicast-group="226.255.1.0" port=5230 ! fakesink dump=1
