Where can we find the FFMPEG source for the cv wrapper?

In the OpenCV source ffmpeg folder there are only dll binaries, but these are for opencv versions of a wrapper.

Where can we download the source to the cv_ffmpeg, as I'd like to add functionality?

i think you should play with cap_ffmpeg_api.hpp and cap_ffmpeg_impl.hpp but i don't know how to compile them exactly. maybe you can find some more information here

Thanks! I'd like to modify and compile the functions such as icvSetCaptureProperty_FFMPEG_p etc., but there is no source code for the binary dll as far as I can see. Have now asked the author, alalek via GitHub.

as seen here

    icvSetCaptureProperty_FFMPEG_p =
        (CvSetCaptureProperty_Plugin)GetProcAddress(icvFFOpenCV, "cvSetCaptureProperty_FFMPEG");

take a look cvSetCaptureProperty_FFMPEG in cap_ffmpeg_impl.hpp.

Yes seen that, the problem is that Alalek says that compiling the wrapper is not easy. I think it has to be done with a variety of tools and is tricky. Its a pity because if conformed with the rest of OpenCV people would be able to add functionality.
