Hi, I am trying to stream an IP camera using RTSP. My code works fine when testing using a big buck bunny stream (either of the two commented out) however when I use the address of the camera it captures only a single frame and only updates that frame on a key press and then eventually crashes. The camera streams fine using its default explorer.
Any help is greatly appreciated, thanks.
