Hi Wiresharkers,
I’m a newbie so please pardon me if I describe my problem clumsily.
Attached is a picture of the way I capture a file.
I do the next:
1. I inject a perfectly clean MPEG stream over UDP into a PC with Ethernet 1Gigabit interface network card.
(I know it’s clean for sure, and anyway I also checked by some reliable testing tools such as StreamXpert running on the same PC, connected to the same interface port)
2. I close all windows, no program is running on the PC. The UDP stream continues flowing in all the time.
3. I open Wireshark, set a capture-file and start recording (I tried with and without filtering only the relevant IP).
4. From the resulting capture-file I’m striping the MPEG stream out of the UDP encapsulation. (did this a hundred times, it’s 100% reliable)
5. in the resulting MPEG stream I get “Continuity-Counter Errors” which means packets were lost or mixed with another stream.
6. Actually, instead of steps 4-5 I later on simply ran Wireshark’s MPEG-TS-checker and indeed the Wireshark itself reported the same CC Errors!
Have you ever encountered such a problem?
Could it be that Wireshark is too weak to record a ~50Mbps stream into a capture file?
What should I do??
Thanks in advance,
Roni
