OpenCV VideoCapture cannot read video in Python but able in VS11
ffmpeg, opencv, python
Solution
I have solved the problem by installing the binaries from this download link provided by this answer.
It copied all opencv DLLs to C:\Python27 (or maybe other files). But I don't understand why it wouldn't work earlier as I have already included those DLLs into my PATH
Problem
As title, I am not able to read video using VideoCapture in python with the following code: ``` v = 'C:\\test.mp4' import cv2 cap = cv2.VideoCapture(v) if cap.isOpened(): print "Finally" else: print "BOOM" ``` BOOM is always being printed. sigh Whereas in VS11, the following code works: ``` #include "stdafx.h" #include <opencv2\highgui\highgui.hpp> #include <iostream> using namespace cv; using namespace std; int main(int argc, char* argv[]) { string v = "C:\\test.mp4"; VideoCapture cap; cap.open(v); if (cap.isOpened()) { cout << "Yes!" << endl; } else { cout << "BOOM" << endl; } return 0; } ``` I do realize there's a number solution in SO, but nothing works for me. I have the following dlls in C:\Python27 and C:\Python27\DLLs, as well as in PATH - opencv_ffmpeg.dll - opencv_ffmpeg_64.dll - opencv_ffmpeg_245_64.dll - opencv_ffmpeg_245.dll I have no more idea what have not done. Please help me. Thank you very much.
