This is a log of my requests and responses. I have a separate thread listening on port 58830 accepting udp packets (Tested sending udp from another computer and were received).

Wireshark shows the requests and response but no udp packets. I looked at the back and forth between server and vlc and my request are almost identical but I still receive no udp video data

Answer 1

Your SDP File's IN ADDR seems invalid 0.0.0.0...

Some stacks use the information in the SDP and this could explain why you are not receiving any packets on the address your are listening on.

Also it looks like you are doing multicast, have you ensured you setup the socket correctly before hand?
