Error opening file (/home/vaibhav/opencv/modules/highgui/src/cap_ffmpeg_impl.hpp:553) in openCV

Question

I am using OpenCV to display a video my code is as

#include
#include
#include
#include

        

Answer 1

I had the same problem. Very annoying (opencv 2.4.9). But what worked for me was passing the absolute file name (avi or mpeg), i.e whole path.

E.g.:

char* fileName = "D:/myVideos/video.avi"
...
VideoCapture capture(fileName );
