Detailed Documentation

VideoCapture API backends identifier.

Select preferred API for a capture object. To be used in the VideoCapture::VideoCapture() constructor or VideoCapture::open()

Backends are available only if they have been built with your OpenCV binaries. See Video I/O with OpenCV Overview for more information.
