How to get frames count of a video file with EmguCV?

Question

I am using the below code to get all the frames from a video file. However, when I run the code for a sample video, double FramesCount is 1402402 and pops an error on frame # 467.

P.S I think the real frames count is around ~467 since the video file is only 15 seconds (15sec * 30fps = ~450 frames)

_capture = new Capture(OpenFile.FileName);
FramesCount = (int)_capture.GetCaptureProperty(Emgu.CV.CvEnum.CAP_PROP.CV_CAP_PROP_FRAME_COUNT);

for(int i = 0; i < FramesCount - 1; i++)
{
    FramesArray.Add(_capture.QueryGrayFrame().Resize(ImageWidth, ImageHeight, Emgu.CV.CvEnum.INTER.CV_INTER_LINEAR));
}

How can I get the exact frames count?

Answer 1

That code:

int framecount = (int)Math.Floor(capt.GetCaptureProperty(CapProp.FrameCount)); //get count of frames   
double framerate = capt.GetCaptureProperty(CapProp.Fps); //get fps

works fine for me if still relevant. I have like 21,6666667 secs video and it return me right count of frames.
