VideoCapture constructors.
-
C++: VideoCapture::VideoCapture()
-
C++: VideoCapture::VideoCapture(const
string&
filename)
-
C++: VideoCapture::VideoCapture(int
device)
-
Python: cv2.VideoCapture() →
<VideoCapture object>
-
Python: cv2.VideoCapture(filename) →
<VideoCapture object>
-
Python: cv2.VideoCapture(device) →
<VideoCapture object>
-
C: CvCapture* cvCaptureFromCAM(int
device)
-
Python: cv.CaptureFromCAM(index) →
CvCapture
-
C: CvCapture* cvCaptureFromFile(const
char*
filename)
-
Python: cv.CaptureFromFile(filename) →
CvCapture
-
| Parameters: |
- filename – name of the opened video file
- device – id of the opened video capturing device (i.e. a camera index). If there is a single camera connected, just pass 0.

Note
In C API, when you finished working with video, release CvCapture structure with cvReleaseCapture(),
or usePtr<CvCapture> that calls cvReleaseCapture() automatically
in the destructor.
