 Summary of the bug:
 When I use udp for rtp communication, I got lot of "rtp: missed packet",
 and the video output is full of mosaic.

 How to reproduce:
 With ffmpeg-2.3, I work with VLC as rtsp server. Stream a mp4 file through
 rtsp without transcoding. On the client side, try below command:
 ffplay "rtsp://192.168.112.21/rtsph2641080p"

 The can see the sympton.

 I tried to search in the forum, and found it similar to #258, #257, and
 #285. But even I tried to disable inside udp.c HAVE_PTHREAD_CANCEL, it
 does not help.

 Thanks in advance for any suggestion.
