WiFi multicast scenario

Hi,

I'm testing this multicast scenario :

1) RPi (multicast video server) connected to AP via ethernet sending
multicast video stream with pipeline :
    raspivid -t 0 -w 960 -h 540 -fps 30 -hf -vf -b 2000000 -o - |
gst-launch-1.0 -e fdsrc ! h264parse ! 
    rtph264pay pt=96 config-interval=5 ! udpsink host=224.1.1.1
multicast-iface=eth0 force-ipv4=true 
    port=5001

2) Two Android devices (TUTORIAL3 multicast video client) connected to AP
via WiFi receiving multicast 
    video stream with pipeline :
    data->pipeline = gst_parse_launch("udpsrc multicast-group=224.1.1.1
auto-multicast=true port=5001 
    ! application/x-rtp, payload=96 ! queue ! rtph264depay ! queue !
h264parse ! decodebin ! eglglessink 
    sync=false", &error);

Everything is ok but when one client goes to onPause() the other client
loses the video stream.

Any idea about what is happening ?.

Thanks in advance and regards.
