Streaming two video streams over RTP in Gstreamer1.0

[Nikolai Smolyansky]

Hello,
I am trying to stream two video streams (H264) over RTP to the client side with GStreamer1.0. The server does encoding and then RTP multiplexing and the client does RTP demultiplexing and then decoding. Both pipelines run OK, but I don't see anything rendered on the client side (xvimagesink windows do not show).
Server:gst-launch-1.0 \  
    rtpmux name=mux ! udpsink host=157.54.158.88 port=5000 \  
    videotestsrc pattern=snow ! 'video/x-raw, format=I420, width=1920, height=1080' ! \  
    omxh264enc ! 'video/x-h264, stream-format=byte-stream' ! h264parse ! \  
    rtph264pay config-interval=1 ! mux.sink_0 \  
    videotestsrc pattern=snow ! 'video/x-raw, format=I420, width=1920, height=1080' ! \  
    omxh264enc ! 'video/x-h264, stream-format=byte-stream' ! h264parse ! \  
    rtph264pay config-interval=1 ! mux.sink_1
Client:gst-launch-1.0 \  
    udpsrc port=5000 ! 'application/x-rtp, encoding-name=H264, payload=96' ! \  
    rtpptdemux name=demux ! \  
    queue ! rtph264depay ! h264parse ! avdec_h264 ! \  
    videoscale ! video/x-raw, width=960, height=540 ! \  
    xvimagesink sync=false demux. ! \  
    queue ! rtph264depay ! h264parse ! avdec_h264 ! \  
    videoscale ! video/x-raw, width=960, height=540 ! xvimagesink sync=false  
Can anyone tell what's wrong with these scripts? Both sides are running, but no videos are rendered on the client side. 
Thank you!
