Troubleshooting OpenCV 2.4 VideoCapture Issues on Windows

Windows users of OpenCV 2.4 bindings may encounter issues when using VideoCapture to open video files. While VideoCapture(0) for webcam access often functions correctly, attempts to use VideoCapture(filename) with an absolute file path consistently return False.

To resolve this problem, ensure that the correct FFmpeg library is accessible to OpenCV. Add the following directory to your Windows PATH environment variable:

C:\OpenCVrdparty\ffmpeg\

Alternatively, copy the opencv_ffmpeg.dll file from this directory to one of the following locations:

• C:Python27
• A directory included in your PATH

In some cases, renaming the opencv_ffmpeg.dll file may also be necessary. Use the following naming conventions:

• For OpenCV version X.Y.Z: opencv_ffmpegXYZ.dll
• For 64-bit OpenCV version X.Y.Z: opencv_ffmpegXYZ_64.dll

By making these adjustments, ensure the availability of the FFmpeg library to OpenCV and resolve the VideoCapture issues on Windows.
