 -   The  **CameraKit**  class provides a group of effective methods for controlling a camera, which facilitates the camera development.
 -   You can create a  **CameraKit**  object and register various callbacks to respond to many events in the multimedia module. Then, create a  **Camera**  object to operate camera resources, for example, to start preview, recording, and stream capturing, and set related parameters.

 -   当使用简单播放录制功能时，可以使用Player和Recorder快速完成播放和录制功能。
 -   提供了一组控制相机的有效接口，可以让用户方便开发使用相机。
 -   开发者先创建camerakit组件对象，注册各种事件回调，这些事件回调是用来响应多媒体模块中事件响应的，之后调用创建camera就可以创建一个操作camera资源的对象，使用这个对象可以启动预览、录像或抓拍取流，及设置取流的相关参数。
