Hi,
Is it possible to get FourCC after openning a video file?
with following code I cannot get FourCC value :
string filename = "f:/video/installBuild.mp4";
VideoCapture cap;
cap.open(filename);
if (!cap.isOpened())
{
cout << "Could not initialize capturing for camera1...\n";
return 0;
}
cout<< "\nCAP_PROP_POS_AVI_RATIO "<< cap.get(CAP_PROP_POS_AVI_RATIO);
cout<< "\nCAP_PROP_POS_FRAMES "<< cap.get(CAP_PROP_POS_FRAMES);
cout<< "\nCAP_PROP_FPS "<< cap.get(CAP_PROP_FPS);
double x=cap.get(CAP_PROP_FOURCC);
cout<< "\nCAP_PROP_FOURCC (double)"<<x;
char *c = (char*)(&x);
cout << "\nCAP_PROP_FOURCC " << c[0]<< c[1]<< c[2]<< c[4];
and result is
