OpenCV - cvQueryFrame + avi file issue

Question

I'm getting some trouble while opening a no compression avi file on Visual Studio 2012 with OpenCV 2.4.5 (I've tried 2.4.2 to 2.4.8 versions) and it give me the following error,

video file c:\ ... \30-1.avi warning: Error opening file (../../modules/highgui/src/cap_ffmepeg_impl.hpp:529) Not able to video file open.

Someone know what to do to fix this issue?

Thanks!!

This is an issue I have been facing recently. What worked for me is copying the ffmpeg related DLL to the application folder. Depending on your configuration, you need to copy opencv_ffmpeg245d.dll for debug or opencv_ffmpeg245.dll for release.

Let me know if that works for you!
