Opencv 3.3 - VideoCapture not working [closed]

I am using visual studio 2015 with opencv 3.3 on windows.

VideoCapture vidCap(fileName);
Mat image;
vidCap.read(image);

But image is empty. I have verified that filename is correct. How do I check what went wrong ? Can anybody tell me what went wrong ?

Comments

try

VideoCapture vidCap(fileName);
Mat frame;
vidCap.read(frame);

^^ indeed, VideoCapture::read() returns a bool, not the image

I have tried that sturkmen but it does not work as well. Berak, where can I find the opencv_ffmpeg340.dll ?

I have edited my code. That is what I have tried but the image is still empty

first search opencv_ffmpeg330_64.dll in your computer
