更改使用CameraCaptureUI[C+；+；]录制的视频的名称 我使用C++和XAML来开发一个UI应用程序。在执行过程中，我使用CameraCaptureUI来录制视频。代码如下所示： CameraCaptureUI^ dialog = ref new CameraCaptureUI(); dialog->VideoSettings->Format = CameraCaptureUIVideoFormat::Mp4; concurrency::task<StorageFile^>(dialog->CaptureFileAsync(CameraCaptureUIMode::Video)).then([this](StorageFile^ file) { if (file != nullptr) { concurrency::task<Streams::IRandomAccessStream^>(file->OpenAsync(FileAccessMode::Read)).then([this](Streams::IRandomAccessStream^ stream) { // CapturedVideo->SetSource(stream, "video/mp4"); logger->Text = "grabando"; }); Windows::Foundation::Collections::IPropertySet^ appSettings = ApplicationData::Current->LocalSettings->Values; appSettings->Insert("CaptureVideo", PropertyValue::CreateString(file->Path)); });

但我的视频库上什么也没出现，也没有错误指引我

我的问题是：如何控制输出视频的名称？我已经搜索了文档和论坛，但似乎找不到解决方案。

查看我找到的文档。因为我已经有了一个StorageFile，所以我可以很容易地更改调用此函数的名称

create_task(StorageLibrary::GetLibraryAsync(KnownLibraryId::Videos))
                .then([this](StorageLibrary^ videosLibrary)
            {
                Windows::Storage::StorageFolder^ _videoLib = videosLibrary->SaveFolder;
                if (_videoLib == nullptr)
                {
                    // In this case fall back to the local app storage since the Pictures Library is not available
                    _videoLib = ApplicationData::Current->LocalFolder;
                }


            });

            //EtiquetaVid is a string created earlier
            file->CopyAsync(_videoLib, stringToPlatformString(etiquetaVid), NameCollisionOption::GenerateUniqueName);
