Please help me. I'am beginer? and i undestend :(
For this code (win 7) i have only about 6.8 FPS. i need 25. How to сapture at higher FPS. thank you.
cap.get(CV_CAP_PROP_FPS)=0
int main()
{
VideoCapture cap(0); // open the video file for reading
if ( !cap.isOpened() ) // if not success, exit program
{
cout << "Cannot open the video file" << endl;
return -1;
}
double fps = cap.get(CV_CAP_PROP_FPS); //get the frames per seconds of the video
if (fps==0)
{
fps=25;
}
cout << "Frame per seconds : " << fps << endl;
CvSize size = cvSize( cap.get( CV_CAP_PROP_FRAME_WIDTH), cap.get( CV_CAP_PROP_FRAME_HEIGHT));
VideoWriter writer = VideoWriter("cap.avi",CV_FOURCC('M','J','P','G'), fps, size, 1);
int cc=0;
while(1)
{
Mat frame;
bool bSuccess = cap.read(frame); // read a new frame from video
if (!bSuccess) //if not success, break loop
{
cout << "Cannot read the frame from video file" << endl;
break;
}
writer.write(frame);
cc++;
if(waitKey(1) == 27)
{
cout << "esc key is pressed by user" << endl;
cout << cc << endl;
waitKey(10000) ;
break;
}
}
writer.release();
return 0;
}
