So as a bit of context; this program was built originally to work with USB cameras - but a few things changed. Now I'm trying to convert it to work with networked cameras, but my presence here should make it quite apparent what my level of success has been so far. I've also asked this same question over on Stack Overflow.

I'm using:

• OpenCV v2.4.6.0
• C++
• D-Link Cloud Camera 7100 (Installer is DCS-7010L, according to the instructions.)

I am trying to access the DLink camera's video feed through OpenCV.

I can access the camera through it's IP address with a browser without any issues. Unfourtunately; my program is less cooperative. When attempting to access the camera the program gives the OpenCV-generated error:

warning: Error opening file (../../modules/highgui/src/cap_ffmpeg_impl.hpp:529)

This error occurs with just about everything I try that doesn't somehow generate more problems.

For reference - the code in OpenCV's cap_ffmpeg_impl.hpp around line 529 is as follows:

522    bool CvCapture_FFMPEG::open( const char* _filename )
523    {
524        unsigned i;
525        bool valid = false;
526
527        close();
528
529    #if LIBAVFORMAT_BUILD >= CALC_FFMPEG_VERSION(52, 111, 0)
530        int err = avformat_open_input(&ic, _filename, NULL, NULL);
531    #else
532        int err = av_open_input_file(&ic, _filename, NULL, 0, NULL);
533    #endif
...
616    }

...for which I have no idea what I'm looking at. It seems to be looking for the ffmpeg version - but I've already installed the latest ffmpeg on that computer, so that shouldn't be the issue.

This is the edited down version I tried to use as per Sebastian Schmitz's recommendation from Stack Overflow:
