Initial stream corruption on second+ stream
Running one of the the simplest rtsp-server commands:
gst-rtsp-server/examples/test-launch 'videotestsrc ! x264enc tune=zerolatency ! rtph264pay name=pay0'
and playback with gst-play-1.0 (note the second gst-play-1.0 is the one that has the corruption):
gst-play-1.0 rtsp://127.0.0.1:8554/test
gst-play-1.0 rtsp://127.0.0.1:8554/test
Shows initial stream corruption of a classic gray image with the libav decoder.
Reverting to before both !147 (merged) and !135 (merged) still results in initial corruption so it has not been fixed by recent related fixes.
