enum cv::VideoCaptureAPIs |
VideoCapture API backends identifier.
Select preferred API for a capture object. To be used in the VideoCapture::VideoCapture() constructor or VideoCapture::open()
VideoCapture generic properties identifier.
Reading / writing properties involves many layers. Some unexpected result might happens along this chain. Effective behaviour depends from device hardware, driver and API Backend.
