VideoCaptureAPIs enum

cv::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 @ref videoio_overview for more information.
• Microsoft Media Foundation backend tries to use hardware accelerated transformations if possible. Environment flag "OPENCV_VIDEOIO_MSMF_ENABLE_HW_TRANSFORMS" set to 0 disables it and may improve initialization time.
