How do I export RTP packets to get IP camera footage?

edit

For a project I am working on I am attempting to intercept an IP camera video stream using Wireshark, and try to have either stills from the camera footage or parts of the stream itself.

I am very new to this so I don't know if its even possible so please excuse the potential naivety.

I am streaming the camera footage through VLC Media Player and am capturing packets in Wireshark from the camera, IP 192.168.0.19, packets include RTSP, RTP, H.264, UDP and TCP.

I was hoping for a way to export some packets and try to display some of the footage, even if it is just still shots from the camera.

Is this even possible and if so an potential methods would be appreciated.
