如何使用Windows.Media.Miracast

Question

我在Windows.Media.Miracast中找到了关于MiracastReceiver的文档。(https://docs.microsoft.com/en-us/uwp/api/windows.media.miracast)但是Windows.Media.Miracast中有太多的类和函数，可能要花很多时间才能理解这些类和接口。有没有开放源代码或示例代码？

非常感谢

如果要转换媒体，请使用Windows.Media.Casting命名空间在远程设备上呈现媒体。包括向各种Miracast设备发送媒体。这是官方code sample。以下是示例代码。目前，我们还没有提供Windows.Media.Miracast的教程或代码示例。我会发邮件给相关团队讨论这个问题，如果我们有任何更新，我会在下面更新。

picker = new CastingDevicePicker();

//Set the picker to filter to video capable casting devices
picker.Filter.SupportsVideo = true;

//Hook up device selected event
picker.CastingDeviceSelected += Picker_CastingDeviceSelected;


private async void Picker_CastingDeviceSelected(CastingDevicePicker sender, CastingDeviceSelectedEventArgs args)
{
    //Casting must occur from the UI thread.  This dispatches the casting calls to the UI thread.
    await Dispatcher.RunAsync(Windows.UI.Core.CoreDispatcherPriority.Normal, async () =>
    {
        //Create a casting conneciton from our selected casting device
        CastingConnection connection = args.SelectedCastingDevice.CreateCastingConnection();

        //Hook up the casting events
        connection.ErrorOccurred += Connection_ErrorOccurred;
        connection.StateChanged += Connection_StateChanged;

        //Cast the content loaded in the media element to the selected casting device
        await connection.RequestStartCastingAsync(video.GetAsCastingSource());
    });
}
