DRC Camera API Functions

Function	Description
CAM_STATE	Enumerates all of the possible camera states.
CAMCheckMemSegmentation	Verifies that the memory allocated by the caller meets the 256 MB hardware limitation. This limitation applies only to the work memory and target decode surface memory.
CAMClose	Stops streaming video frames from the DRC camera. All the underlying drivers go to a quiescent state, and the target surfaces are not touched.
CAMEventHandler	Callback function that the camera library uses to tell the application that an event occurred.
CAMExit	Disables the video decode hardware (UVD) and frees all of the driver resources.
CAMGetMemReq	Utility that queries the camera library for the size of memory required to stream video frames from the DRC camera.
CAMGetState	Gets the value of the camera state.
CAMGetStateInfo	Populates the CAMStateInfo structure for the desired camera state.
CAMHandle	A handle that is issued by the camera driver during initialization of the DRC device. It is used to reference that device in camera library function calls.
CAMInit	Validates the given parameters, and then initializes the driver stack and video decode hardware (UVD).
CAMMode	Stores camera mode settings.
CAMOpen	Starts streaming compressed video frames from the selected DRC camera. Streaming continues until CAMClose is called.
CAMSetState	Sets the value of a camera state. CAMSetState does not support all camera states.
CAMSetupInfo	Stores all information necessary to initialize the camera library.
CAMStreamInfo	Encapsulates camera stream key properties, such as height and width of the frames.
CAMSubmitTargetSurface	Submits a decode target surface to the camera driver. The driver adds the surface to an internal FIFO, and the call returns without further processing.
CAMSurface	Stores information about the decode target surface.
CAMWorkMem	Encapsulates the working memory the camera library requires.
