MediaComposition.RenderToFileAsync 方法

定义

命名空间:

Windows.Media.Editing

重载

RenderToFileAsync(IStorageFile)	将 MediaComposition 异步呈现到指定的文件。
RenderToFileAsync(IStorageFile, MediaTrimmingPreference)	使用指示的媒体剪裁首选项将 MediaComposition 异步呈现到指定的文件。
RenderToFileAsync(IStorageFile, MediaTrimmingPreference, MediaEncodingProfile)	使用指示的媒体剪裁首选项和编码配置文件将 MediaComposition 异步呈现到指定的文件。

RenderToFileAsync(IStorageFile)

将 MediaComposition 异步呈现到指定的文件。

public:
 virtual IAsyncOperationWithProgress<TranscodeFailureReason, double> ^ RenderToFileAsync(IStorageFile ^ destination) = RenderToFileAsync;

/// [Windows.Foundation.Metadata.Overload("RenderToFileAsync")]
/// [Windows.Foundation.Metadata.RemoteAsync]
IAsyncOperationWithProgress<TranscodeFailureReason, double> RenderToFileAsync(IStorageFile const& destination);

[Windows.Foundation.Metadata.Overload("RenderToFileAsync")]
[Windows.Foundation.Metadata.RemoteAsync]
public IAsyncOperationWithProgress<TranscodeFailureReason,double> RenderToFileAsync(IStorageFile destination);

function renderToFileAsync(destination)

Public Function RenderToFileAsync (destination As IStorageFile) As IAsyncOperationWithProgress(Of TranscodeFailureReason, Double)

参数

destination

IStorageFile

此 MediaComposition 要呈现到的文件。

返回

IAsyncOperationWithProgress<TranscodeFailureReason,Double>

IAsyncOperationWithProgress<TranscodeFailureReason,double>

可用于跟踪操作成功或失败的异步操作。

属性

OverloadAttribute RemoteAsyncAttribute

注解

此方法将合成保存到可使用标准媒体播放器播放的视频文件中。 如果要将合成另存为将来可以加载和修改的 XML 文件，请使用 SaveAsync。
