[Live-devel] ~H264VideoRTPSink bug

[Emiliano Parasassi]

Hi Ross,
I'm playing with H264 and seems to be a SEGV during the deletion of H264VideoRTPSink
during the RTSP DESCRIBE handler.
The ~H264VideoRTPSink destrucor misses the fSource = NULL. This fSource was replaced by
H264FUAFragmenter at H264VideoRTPSink.cpp:76.
So in the frame #1 the stopGettingFrames() function is called to an already freed object.
