标题: 编写一个小而强大的 Windows 动态屏保壁纸
写在前面

两年前我做了第一个开源软件 DreamScene2 动态桌面，如今受到了很多人的喜欢，这增加了我继续做好开源软件的信心。之前的这个软件一直有人希望我加入一个设置屏保壁纸的功能，因为 DreamScene2 就是一个单纯的动态桌面的软件，所以一直没有加入这个功能。今天我带来一个新的开源软件，软件依然是小而强大，简洁并且快速。
欢迎 Star 和 Fork: https://github.com/he55/SonomaWallpaper
介绍

Sonoma Wallpaper 是首款将 macOS Sonoma 4k 120 帧动态屏保壁纸带到 Windows 11 的软件，壁纸包含了自然景观、城市景观、水下景观和地球四个主题的屏保共有 134 个 4k 屏保壁纸。

  功能

• 4k 120 帧率视频播放
  
• 多语言
  
• 高 dpi 支持
  
• 深色模式
  
• 多任务下载
  
• Windows 11 支持
  

如何使用

选中已下载的视频壁纸，然后打开 显示为屏幕保护程序 开关，程序会在 2 分钟系统无操作时自动播放屏保壁纸。
下载壁纸

• 选择一个壁纸点击下载
  

  

• 等待壁纸下载完成
  

  

• 壁纸下载完成后，可以点击预览按钮看效果
  

  视频播放功能代码

在解码 4k 120 帧视频的时候我试过 VLC、迅雷的 APlayer、mpv、ffmpeg、PotPlayer 这些引擎或播放器，发现在 Windows 10 上它们对 120 帧视频支持的都不好。最后发现 Windows 11 已经原生支持了 120 帧视频播放，但只有 UWP 和 WinUI3 程序原生支持。WPF 要使用 UWP 的控件需要安装 Microsoft.Toolkit.Wpf.UI.XamlHost 这个 NuGet 包，这个包可以让 Win32 程序调用 UWP 的控件。包安装后在 xaml 文件中添加名称空间 xmlns:xamlhost="clr-namespace:Microsoft.Toolkit.Wpf.UI.XamlHost;assembly=Microsoft.Toolkit.Wpf.UI.XamlHost"，然后添加 WindowsXamlHost 控件用来显示 UWP 的 MediaPlayerElement 媒体播放控件。
完整代码如下

1. <Window x:
2.         xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
3.         xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

11.         ChildChanged="WindowsXamlHost_ChildChanged"
12.         InitialTypeName="Windows.UI.Xaml.Controls.MediaPlayerElement" />
13. </Window>

复制代码

添加 ChildChanged 事件用来处理 MediaPlayerElement 控件创建成功后的要做的事情

• Stretch 设置视频拉伸模式
  
• Source 设置播放文件路径
  
• AutoPlay 设置自动播放
  
• IsMuted 设置静音
  
• IsLoopingEnabled 设置循环播放
