 Summary of the bug:
 Hi,
 I'm transcoding a bunch of SD sources from SPTS mpegts transported on
 different multicast addresses with RTP on port 5530. (VBR h264 video, mp2
 audio)
 When I transcode the first source from mcast IP1:5530 the output is sort
 of OK (occasional green patches and false reporting of unsupported source
 features)
 Once I run a second ffmpeg instance to transcode source IP2:5530 the
 second instance is not ingesting IP2 content but IP1 and both instances
 start to interfere and they don't even come to a state to start
 transcoding.
 It's bizare that even two ffplay instances tuned to different sources play
 back the same content!
 I tried playing back with vlc and there is no such problem.

 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
