媒体子系统 JS API 变更 Changelog

cl.subsystemname.1 camera 接口变更

  1. camera 部件在 API9 版本全量改为 SystemAPI
  2. 基于以下原因新增部分功能接口以及废弃部分接口:

提升开发者使用相机接口的便利。 帮助开发者快速掌握相机开发接口,快速投入到开发当中。 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。

   PhotoOutput.on('error', (BusinessError) => {
   
   })
  1. VideoOutput 中,on(type: ‘error’) callback 类型由 ErrorCallback 变更为 ErrorCallback,因此旧接口 on(type: ‘error’, callback: ErrorCallback): void; 变更为 on(type: ‘error’, callback: ErrorCallback): void;

参考代码如下:

   VideoOutput.on('error', (BusinessError) => {
   
   })
  1. MetadataOutput 中,on(type: ‘error’) callback 类型由 ErrorCallback 变更为 ErrorCallback,因此旧接口 on(type: ‘error’, callback: ErrorCallback): void; 变更为 on(type: ‘error’, callback: ErrorCallback): void;

参考代码如下:

   MetadataOutput.on('error', (BusinessError) => {
   
   })
