# 媒体子系统JS API变更Changelog

## camera接口变更
基于以下原因新增部分功能接口以及废弃部分接口：
1. 提升开发者使用相机接口的便利。
2. 帮助开发者快速掌握相机开发接口，快速投入到开发当中。
3. 易于后续版本中框架功能的扩展，降低框架模块之间的耦合度。

具体参考下方变更内容，开发者需要根据以下说明对应用进行适配。

 **变更影响**

影响API9版本的JS接口，应用需要进行适配才可以在新版本SDK环境正常实现功能。

**关键的接口/组件变更**

   参考代码如下：

   ```
   let profile = cameraoutputcapability.videoProfiles[0];
   cameraManager.createVideoOutput(profile, surfaceId, (err, videoOutput) => {
       if (err) {
           console.error(`Failed to create videoOutput. ${err.message}`);

   })
   ```

6. CameraManager中接口createMetadataOutput新增传递参数metadataObjectTypes: Array<MetadataObjectType>,metadataObjectTypes参数由getSupportedOutputCapability接口获取，因此旧接口function createMetadataOutput(callback: AsyncCallback<MetadataOutput>): void;以及function createMetadataOutput(): Promise<MetadataOutput>;变更为createMetadataOutput(metadataObjectTypes: Array<MetadataObjectType>, callback: AsyncCallback<MetadataOutput>): void;和createMetadataOutput(metadataObjectTypes: Array<MetadataObjectType>): Promise<MetadataOutput>;

   let metadataObjectTypes = cameraoutputcapability.supportedMetadataObjectTypes;
   cameraManager.createMetadataOutput(metadataObjectTypes).then((metadataOutput) => {
       console.log('Promise returned with metadataOutput created.');
   })
   ```
   
7. CameraManager中createCaptureSession不需要考虑context属性，因此旧接口createCaptureSession(context: Context, callback: AsyncCallback<CaptureSession>): void;以及createCaptureSession(context: Context): Promise<CaptureSession>;改为createCaptureSession(callback: AsyncCallback<CaptureSession>): void;和createCaptureSession(): Promise<CaptureSession>;

   参考代码如下：

   ```typescript
   cameraManager.createCaptureSession((err, captureSession) => {
       if (err) {
           console.error(`Failed to create captureSession. ${err.message}`);
           return;
       }
       console.log('Callback returned with captureSession created.');
   })
   ```

   ```
   cameraManager.createCaptureSession().then((captureSession) => {
       console.log('Promise returned with captureSession created.');
   })
   ```

8. CameraStatusInfo接口下属性camera类型由Camera变更为CameraDevice

9. CameraInput中接口on(type: 'error'）新增传递参数camera: CameraDevice，因此旧接口on(type: 'error', callback: ErrorCallback<CameraInputError>): void;变更为on(type: 'error', camera: CameraDevice, callback: ErrorCallback<CameraInputError>): void;

   参考代码如下：

   ```
   let cameraDevice = cameras[0];
   cameraInput.on('error', cameraDevice, (cameraInputError) => {
       console.log(`Camera input error code: ${cameraInputError.code}`);
   })
   ```
	
10. CameraInput中以下接口调整到CaptureSession中

    hasFlash(callback: AsyncCallback<boolean>): void;<br/>hasFlash(): Promise<boolean>;<br/>

    isFlashModeSupported(flashMode: FlashMode, callback: AsyncCallback<boolean>): void;<br/>isFlashModeSupported(flashMode: FlashMode): Promise<boolean>;<br/>

    getFlashMode(callback: AsyncCallback<FlashMode>): void;<br/>getFlashMode(): Promise<FlashMode>;<br/>

    setFlashMode(flashMode: FlashMode, callback: AsyncCallback<void>): void;<br/>setFlashMode(flashMode: FlashMode): Promise<void>;<br/>

    isExposureModeSupported(aeMode: ExposureMode, callback: AsyncCallback<boolean>): void;<br/>isExposureModeSupported(aeMode: ExposureMode): Promise<boolean>;<br/>

    getExposureMode(callback: AsyncCallback<ExposureMode>): void;<br/>getExposureMode(): Promise<ExposureMode>;<br/>

    setExposureMode(aeMode: ExposureMode, callback: AsyncCallback<void>): void;<br/>setExposureMode(aeMode: ExposureMode): Promise<void>;<br/>

    setMeteringPoint(point: Point, callback: AsyncCallback<void>): void;<br/>setMeteringPoint(point: Point): Promise<void>;<br/>

    getExposureBiasRange(callback: AsyncCallback<Array<number>>): void;<br/>getExposureBiasRange(): Promise<Array<number>>;<br/>

    setExposureBias(exposureBias: number, callback: AsyncCallback<void>): void;<br/>setExposureBias(exposureBias: number): Promise<void>;<br/>

    getExposureValue(callback: AsyncCallback<number>): void;<br/>getExposureValue(): Promise<number>;<br/>

    isFocusModeSupported(afMode: FocusMode, callback: AsyncCallback<boolean>): void;<br/>isFocusModeSupported(afMode: FocusMode): Promise<boolean>;<br/>

    getFocusMode(callback: AsyncCallback<FocusMode>): void;<br/>getFocusMode(): Promise<FocusMode>;<br/>

    setFocusMode(afMode: FocusMode, callback: AsyncCallback<void>): void;<br/>setFocusMode(afMode: FocusMode): Promise<void>;<br/>

    setFocusPoint(point: Point, callback: AsyncCallback<void>): void;<br/>setFocusPoint(point: Point): Promise<void>;<br/>

    getFocusPoint(callback: AsyncCallback<Point>): void;<br/>getFocusPoint(): Promise<Point>;<br/>

    getFocalLength(callback: AsyncCallback<number>): void;<br/>getFocalLength(): Promise<number>;<br/>

    getZoomRatioRange(callback: AsyncCallback<Array<number>>): void;<br/>getZoomRatioRange(): Promise<Array<number>>;<br/>

    setZoomRatio(zoomRatio: number, callback: AsyncCallback<void>): void;<br/>setZoomRatio(zoomRatio: number): Promise<void>;
	
11. CameraInput中接口on(type: 'focusStateChange', callback: AsyncCallback<FocusState>): void;调整到CaptureSession中，对应接口on(type: 'focusStateChange', callback: AsyncCallback<FocusState>): void;

    参考代码如下：

    ```
    captureSession.on('focusStateChange', (focusState) => {
        console.log(`Focus state  : ${focusState}`);
    })
    ```

12. 枚举ExposureMode中

    枚举值名称：EXPOSURE_MODE_AUTO，初值由默认变更为1;

    枚举值名称：EXPOSURE_MODE_CONTINUOUS_AUTO，初值由默认变更为2;

13. 枚举VideoStabilizationMode中

    枚举值名称：LOW，初值由默认变更为1;

    枚举值名称：MIDDLE，初值由默认变更为2;

    枚举值名称：HIGH，初值由默认变更为3;

    枚举值名称：AUTO，初值由默认变更为4;

14. CaptureSession中接口addOutput参数由原来子类类型（PreviewOutput，PhotoOutput，VideoOutput，MetadataOutput）统一修改为基类类型（CameraOutput），变更后由原来8个接口缩减为2个接口。

    改变前接口为：

    addOutput(previewOutput: PreviewOutput, callback: AsyncCallback<void>): void;<br/>addOutput(previewOutput: PreviewOutput): Promise<void>;<br/>addOutput(photoOutput: PhotoOutput, callback: AsyncCallback<void>): void;<br/>addOutput(photoOutput: PhotoOutput): Promise<void>;<br/>addOutput(videoOutput: VideoOutput, callback: AsyncCallback<void>): void;<br/>addOutput(videoOutput: VideoOutput): Promise<void>;<br/>addOutput(metadataOutput: MetadataOutput, callback: AsyncCallback<void>): void;<br/>addOutput(metadataOutput: MetadataOutput): Promise<void>;

    改变后接口为：

    addOutput(cameraOutput: CameraOutput, callback: AsyncCallback<void>): void;<br/>addOutput(cameraOutput: CameraOutput): Promise<void>;

    参考代码如下：以PreviewOutput为例

    ```
    captureSession.addOutput(previewOutput, (err) => {
        if (err) {
            console.error(`Failed to add output. ${err.message}`);
            return;
        }
        console.log('Callback returned with output added.');
    })
    ```

    ```
    captureSession.addOutput(previewOutput).then(() => {
        console.log('Promise returned with cameraOutput added.');
    })
    ```

15. CaptureSession中接口removeOutput参数由原来子类类型（PreviewOutput，PhotoOutput，VideoOutput，MetadataOutput）统一修改为基类类型（CameraOutput），变更后由原来8个接口缩减为2个接口。

    改变前接口为：

    removeOutput(previewOutput: PreviewOutput, callback: AsyncCallback<void>): void;<br/>removeOutput(previewOutput: PreviewOutput): Promise<void>;<br/>removeOutput(photoOutput: PhotoOutput, callback: AsyncCallback<void>): void;<br/>removeOutput(photoOutput: PhotoOutput): Promise<void>;<br/>removeOutput(videoOutput: VideoOutput, callback: AsyncCallback<void>): void;<br/>removeOutput(videoOutput: VideoOutput): Promise<void>;<br/>removeOutput(metadataOutput: MetadataOutput, callback: AsyncCallback<void>): void;<br/>removeOutput(metadataOutput: MetadataOutput): Promise<void>;

    改变后接口为：

    removeOutput(cameraOutput: CameraOutput, callback: AsyncCallback<void>): void;<br/>removeOutput(cameraOutput: CameraOutput): Promise<void>;

    参考代码如下：以PreviewOutput为例

    ```
    captureSession.removeOutput(previewOutput, (err) => {
        if (err) {
            console.error(`Failed to remove the CameraOutput instance. ${err.message}`);
            return;
        }
        console.log('Callback invoked to indicate that the CameraOutput instance is removed.');
    });
    ```

    ```
    captureSession.removeOutput(previewOutput).then(() => {
        console.log('Promise returned to indicate that the CameraOutput instance is removed.');
    })
    ```

16. 枚举MetadataObjectType中

    枚举值名称由FACE变更为FACE_DETECTION;

17. 接口Camera名称更改为CameraDevice
