└── bundle.json                        # 部件描述文件
```

## 编译构建

通过如下编译命令：

```
hb build cast
```
在out目录对应产品的文件夹中生成如下产物：
```
libcast.z.so
libcast_engine_client.z.so
libcast_engine_service.z.so
```


### 使用说明

提供整体的投播框架，支持其他投屏协议的接入以及投屏协议自适应选择。
北向接入可参考[Sample](https://gitee.com/openharmony/applications_app_samples/tree/master/code/BasicFeature/Media/AVSession)。
