Hi,
  Goggling for VLC player found http://www.videolan.org/vlc/ very breifly looking at the info it looks like there are several options
for how the video stream is sent if it really is RTP in your case you could use decode as and select RTP and then use the RTP analysis
Note that it designed to analyse Audio and some values may not be entirely correct/applicable for Video.

You can also use the IO-graph to calculate the  bandwidth. If RTP isn't used you may have to digg trough the documentation/sources
of the VLC player to find out if you can do the calculations you need. You may have to export the data from the RTP analysis and perform your own calculation from the raw data or update Wiresharks sources to do it for you. You may also have to know what codec(s) are used to do correct calculation. You must also consider where your traces are made and perhaps compare results
from the sender side with results on the receiver side. No easy answers here :-)
Regards
Anders

Hi Antony ,
  Thanxs for your response. What does this mean "RTP is commonly carried within UDP" ?? I found that wireshark provide support for RTP as http://wiki.wireshark.org/RTP_statistics . If i need to calculate jitter,bandwith etc. What should i use. How can i use UDP

Hi Ankur,

RTP is commonly carried within UDP. Although this is not mandatory, there are other possible underlying protocols such as AAL5.

Regards,

Anthony

Hello All,
  I am a new user of wireshark. I am working on stream video packets and receving at other end through wireless hops (Access point). I used to do this using VLC player and thru UDP protocol. I started using Wireshark for analysis of my packets. In between i found we cannot calculate jitter , delay etc.. through UDP. Later i found RTP protocol. Now the question is what exactly is the difference between UDP and RTP in term of networking and in term of Wireshark s/w working. 

I need some proof as this information will be needed for my publication.
Help me plz
