That's strange. I'm not able to see this code in gmail (in web
browser)! Even the debug o/p that you send in this mail (below) is not
viewable on gmail. I can see it on the web link you sent though.

The link between your udpsrc and decoder seems to be broken. I don't
know why. Could you try removing the queue before the decoder? I've
heard of similar issues when a queue was present before a decoder.
Maybe some other expert here can tell as to why that is (i.e if
removing it works).

Also, remember to check the return value of your setState() calls just
to make sure they did not return an error.
