Wireshark-users: Re: [Wireshark-users] Crosscompiling TSHARK to run on embedded linux on ppc440!

I'm streaming a video sequence via vlc using UDP and trying to detect packet loss, jitter and delay. Following is the command issued while trying to detect these parameters. tshark -i 6 -a duration:10  -d udp.port==1234,rtp -z rtp,streams I'm using WANem to emulate packet loss, jitter and delay. (-- If you know any other packet emulator program please don't hesitate to let me know) But I can't seem to detect anything besides the packet loss. Tshark is necessary as I am running it on a embedded linux. When I use wireshark on a windows xp machine and decode udp to rtp in the "Analyze -> Decode as" menu I can see some Jitter (ms) and Delta (ms) for each packet in the "Statistics -> RTP -> Stream Analysis" menu but when I choose the "Statistics -> RTP -> Show All Streams" menu I can't see Max Delta, MAX Jitter and Mean Jitter. These just show zero. I believe that the "Show All Streams" menu corresponds to the tshark command as stated above. One more question: I have installed a tshark rpm on my embedded linux which doesn't seem to have the -z rtp,streams option (It has the "-z" option but not the "rtp,streams") as I think it is a old version of tshark. Do I have to find a newer version or can i add the option to tshark somehow??? Thanks in advance!   What can you do with the new Windows Live? Find out
