Fixed assert for multi cast (2.51 KB, patch)

Description Srimanta Panda (trollkarlen) 2016-01-05 10:34:20 UTC 
With new update of RTSP Server, we only add RTP sending/receiving pad if needed.

But while trying to update the transport during create media for multicast case, gives a assert. In the function update_transport() in rtsp-stream.c, we try to get the parent of funnel (0) element, but that element doesn't exist sometimes. This is a regression from a earlier commit (SHA1: 61772cb rtsp-stream: Only create RTP sending/receiving rtpbin pads if needed).

Testing my fix, soon provide a patch for it.

    rtsp-stream: fixed assert during update transport
    
    When RTSP server trying update transport during multicast, it throws an
    assert. The assert is thrown because it is trying to get the parent of
    an non-existing funnel element.
