okay, I got this. The value of the packet switches to 22 from 11, and so on.

which is "unable" to play any kind of audio even at the first time, when
the value of packets column becomes 22 from 11. Now is this happening only
with me. After this I tried with the aaa.pcap sample packet also, the value
of the "packet" column is changing randomly, and "RTP player is unable to
play the stream" (not even the first time). Is the RTP player thing is
happening just with me, is there anyone who is also working on the same bug?
