Hi, my IDE is QT Creator 5.7.0, compiling with MSVC (2015). I use the OpenCV 3.4.0 My OS is Windows 7 (64 Bit)
When i try to capture and "imshow" the .avi -Video, there is popping up only a gray Window and when the Video is ending, it Shows the last Picture of the Video.
Is it a Problem with opencv_ffmpeg340_64.dll? I still tried to set the Path-Variables, to copy the .dll into the debug Folder, etc.
// Auswahl Video
cv::VideoCapture cap("Regen_02_400fps_K3Stellung_170Belichtung.avi");
// Meldung wenn Video nicht gefunden wird
if (!cap.isOpened())
std::cout<<"Error when reading steam";
//cv::namedWindow("Original");
for(;;)
{
cap.read(frame);
// Abbruch wenn kein Frame mehr gefunden wird
if (!cap.read(frame))
break;
cv::imshow("Original", frame);
cv::waitKey(25);
// Abfolge "Geschwindigkeit" mit WaitKey
char key = cvWaitKey(50);
// ESC drücken um zu unterbrechen
if (key == 27)
break;
}
