-**Media**: provides playback and recording APIs for applications, and invokes the Gstreamer, Histreamer, or other engines through cross-process calling or direct calling.
- For the mini system, the media component invokes Histreamer to support audio playback.
- For the small system, the media component invokes recorder_lite to support audio/video recording and invokes player_lite by default to support audio/video playback. If the system variable **debug.media_service.histreamer** is set to **1**, the component invokes Histreamer to support audio/video playback.

You can use the APIs in any of the provided classes based on your development requirements.
- For details about how to call media APIs to implement the video recording, preview, and playback, see [Multimedia Development Guide](https://gitee.com/openharmony/docs/blob/master/en/device-dev/subsystems/subsys-multimedia.md).
- For details about how to call media APIs to implement the video recording, preview, and playback, see [Multimedia Development Guide](https://gitee.com/openharmony/docs/tree/master/en/application-dev/media).
- For a simple player, use **Player** and **Recorder** classes to quickly implement the playback and recording features.
- 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.
