Using the AXIS camera (M1011) with OpenCV
So, I am using cv::CvCapture to get video. This code works with my internal webcam (cvCaptureFromCAM(0);. However, when I switch to reading from the net-cam (AXIS M1011), my app keeps crashing and OpenCV says that it can't find "../../modules/highgui/src/cap_ffmpeg_impl.hpp(545)"
What am I doing wring and why is it triggering?
the code is below.
PHP Code:

Thank goodness that CD shrinks the CODE box! Otherwise this post would be a couple pages long 
Thanks!
