	Optional apiPreference As VideoCaptureAPIs = VideoCaptureAPIs.ANY
) As VideoCapture

public:
static VideoCapture^ FromCamera(
	int index, 
	VideoCaptureAPIs apiPreference = VideoCaptureAPIs::ANY
)

static member FromCamera : 
        index : int * 
        ?apiPreference : VideoCaptureAPIs 
(* Defaults:
        let _apiPreference = defaultArg apiPreference VideoCaptureAPIs.ANY
*)
-> VideoCapture 

Parameters

index

Type: SystemInt32
id of the video capturing device to open. To open default camera using default backend just pass 0. (to backward compatibility usage of camera_id + domain_offset (CAP_*) is valid when apiPreference is CAP_ANY)

apiPreference (Optional)

Type: OpenCvSharpVideoCaptureAPIs
preferred Capture API backends to use. Can be used to enforce a specific reader implementation if multiple are available: e.g. cv::CAP_DSHOW or cv::CAP_MSMF or cv::CAP_V4L.
