Hi. How to play a live network transport stream by opencv in Windows7?

VideoCapture cap;

cap.open("rtp://234.1.2.3:1234); //works nice

but

cap.open("udp://234.1.2.3:1234); //does not work

I've gotten UDP to work before for me(openCV 2.4.9). check your quotes there, looks like you are missing one. Then make sure that you are not opening the stream up elsewhere (like vlc on the side).

There is nu UDP support inside OpenCV, but there do exist interesting additional libraries like this one that could easily solve your problem and can operate besides OpenCV.

This is nice, but my TS contains not jpeg frames, but H264 video

Hmm no way of converting to frames first?
