MediaCapture.PrepareLowLagPhotoSequenceCaptureAsync 方法

定义

命名空间:

Windows.Media.Capture

初始化低快门延迟照片序列捕获，并提供用于管理录制的 LowLagPhotoSequenceCapture 对象。

public:
 virtual IAsyncOperation<LowLagPhotoSequenceCapture ^> ^ PrepareLowLagPhotoSequenceCaptureAsync(ImageEncodingProperties ^ type) = PrepareLowLagPhotoSequenceCaptureAsync;

/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperation<LowLagPhotoSequenceCapture> PrepareLowLagPhotoSequenceCaptureAsync(ImageEncodingProperties const& type);

[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperation<LowLagPhotoSequenceCapture> PrepareLowLagPhotoSequenceCaptureAsync(ImageEncodingProperties type);

function prepareLowLagPhotoSequenceCaptureAsync(type)

Public Function PrepareLowLagPhotoSequenceCaptureAsync (type As ImageEncodingProperties) As IAsyncOperation(Of LowLagPhotoSequenceCapture)

参数

type

ImageEncodingProperties

用于图像的编码配置文件。

返回

IAsyncOperation<LowLagPhotoSequenceCapture>

此方法完成后，将返回 LowLagPhotoSequenceCapture 对象，该对象可用于启动照片序列捕获。

属性

RemoteAsyncAttribute

Windows 要求

应用功能	backgroundMediaRecording

注解

使用 MediaCapture.PrepareLowLagPhotoSequenceCaptureAsync 初始化照片序列捕获。 这是一个异步调用，它在完成时返回 LowLagPhotoSequenceCapture 对象，该对象通过调用 LowLagPhotoSequenceCapture.StartAsync 来启动照片序列捕获。

在 LowLagPhotoSequenceCapture.StartAsync 之前，必须调用 PrepareLowLagPhotoSequenceCaptureAsync。
