Playback Issues

asked 2021-01-20 15:18:54 +0000

I've got an application "A" that publishes an IP stream to a multicast address and a second applications "B" that receives the data and displays it. I've captured the stream from "A" using Wireshark 3.4.2 and tried playing it back using Bit-twist 2.0 and application "B" isn't receiving the data. I've used Wireshark to verify the data is playing back using the same IP source, destination, and port. I've capture the playback from Bit-twist using Wireshark and compared it to the captured stream from "A" and they appear identical to me.

Any obvious things I should be looking at? I'm guessing there's a difference in a header somewhere. I'm doing all of this inside a Windows 10 Virtual Machine.

We ended up putting "A" and "B" on separate Virtual Machines. We then recorded the stream from "A" using Wireshark on the VM running "B" and were able to play back the file using Bittwist. Obviously some sort of header issue.

Hopefully this update will help someone else.
