Parameters

handle	[OUT] It refers to the frame grabber handle.
pInterfaceInfo	[IN] It refers to frame grabber information.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Note

This API is not available in ARM and Linux 32 systems.

MV_CC_CreateInterfaceByID()

def MvCameraControl_class.MV_CC_CreateInterfaceByID	(		self,
			InterfaceID
	)

Creates frame grabber handle by frame grabber ID.

Parameters

pInterfaceInfo	[IN] It refers to the frame grabber handle.
pInterfaceID	[IN] It refers to the frame grabber ID.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Note

This API is not available in ARM and Linux 32 systems.

MV_CC_OpenInterface()

def MvCameraControl_class.MV_CC_OpenInterface

Turns off the frame grabber.

Parameters

handle

[IN] It refers to the frame grabber handle.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Note

This API is not available in ARM and Linux 32 systems.

MV_CC_DestroyInterface()

def MvCameraControl_class.MV_CC_DestroyInterface

Destroys the frame grabber handle.

Parameters

handle

[IN] It refers to the frame grabber handle.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Remarks

If camera handle is passed, the camera handle will be destroyed.

Note

This API is not available in ARM and Linux 32 systems.

MV_CC_EnumDevicesByInterface()

def MvCameraControl_class.MV_CC_EnumDevicesByInterface	(		self,
			stDevList
	)

Enumerates devices by frame grabber handle.

Parameters

handle	[IN] It refers to the frame grabber handle.
pstDevList	[OUT] It refers to device list.

Returns

Returns MV_OK for success, and returns corresponding Error Code for failure.

Remarks

The memory of device list is internally allocated. When this API is called in multiple threads, the SDK will release and apply for the device list memory. It is recommended to avoid multithreaded enumeration operations.
