LowLagMediaRecording.StartAsync 方法

定义

命名空间:

Windows.Media.Capture

异步启动低滞后媒体录制。

public:
 virtual IAsyncAction ^ StartAsync() = StartAsync;

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncAction StartAsync();

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncAction StartAsync();

function startAsync()

Public Function StartAsync () As IAsyncAction

返回

IAsyncAction

用于控制异步操作的对象。

属性

RemoteAsyncAttribute

注解

在调用 StartAsync 之前，必须通过在 MediaCapture 上调用 prepare 方法之一来初始化 LowLagMediaRecording 对象：PrepareLowLagRecordToStreamAsync、PrepareLowLagRecordToStorageFileAsync 和 PrepareLowLagRecordToCustomSinkAsync。
