your VideoCapture either did not open, or you reached the end of the movie. anyway, your image is invalid

please:

  • check cap.isOpened()

  • and the ret value in: ret,frame = cap.read()


if any of it returns False, you have to handle that condition. (i.e. break out of the loop)

if you're using a video file, make sure, that opencv_ffmpeg340_x64.dll is on your PATH
