How it works...

As in the earlier recipes, working with cameras and video frame streams is done through the cv2.VideoCapture class. You can get properties using the capture.get function, which takes the property ID and returns its value as a floating-point value.

Note that, depending on the OS and video backend used, not all of the properties being requested can be accessed. 

The following output is expected (it might vary depending on the OS and the video backend that OpenCV was compiled with):

Created capture: ../data/drop.avi
Frame count: 182
Frame width: 256
Frame height: 240
Frame rate: 30.0

Created capture: 0 
Frame count: -1 
Frame width: 640 
Frame height: 480 
Frame rate: 30.0
