Hello Everyone !!

I want to generate video file from the ethernet camera data captured by Wireshark. Is there any way to do it? I have data received using UDP protocol and stored in PCAP format.

I'm new to wireshark and if this question has been asked previously, pl redirect.

Kindly help.

Thanks!

Same data now I'm sending through a wireless network. This is where the issue starts. I could somehow see that I'm receiving UDP data of same length to my end receiver system; however, I'm not able to play the video. I'm receiving data on wireshark and ...(more)

Stack Overflow post that points to mpeg_dump.lua on the Wireshark Wiki.
