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!!

Please post the code snippet where the error is occuring. – scap3y Feb 05 '14 at 17:09 — scap3y, Feb 05 '14 at 17:09
You are most likely missing a ffmpeg codec – Hannes Ovrén Feb 05 '14 at 17:39 — Hannes Ovrén, Feb 05 '14 at 17:39
How to install ffmpeg codec? Can you help me with it? – MSO Feb 05 '14 at 17:50 — MSO, Feb 05 '14 at 17:50

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!
