Description

Hi
I have been trying to use couple of Apis with OpenCV to access frame data from a video.
I use cvCaptureFromFile() followed by QueryFrame() and for uncompressed avi it works totally fine.
But it has some problem with mov and mp4 files.
It doesn't through any error message and crashes with System.AccessViolationException.

CvCapture *capture = cvCaptureFromFile(video_file.c_str()); //fails right here. video_file does exists 
        if(!capture) 
{
            cout << "Capture from AVI didn't work" << endl;
            return FALSE;
        }

I also tried VideoCapture Api, but have the same issue.

So, I want to know which formats are supported for vides.
Do you need to do some steps for getting mov and mp4 working?

Its very important and is blocking me from releasing.
Please help me with this one asap
