在今天的博文中，我们将描述为什么在Windows 10中需要DirectX 9 覆盖^{(DirectX 9 overlays)}时视频播放可能会失败- 然后提供解决该问题的解决方法。DirectX是Windows中的一组组件，它允许软件（主要是游戏）直接与您的视频和音频硬件一起工作。使用DirectX的游戏可以更有效地使用硬件内置的多媒体加速器功能，从而改善您的整体多媒体体验。

早期版本的Microsoft Windows（XP 和更早版本）具有多个必须单独安装的DirectX版本。^(DirectX)更高^(Later)版本的Windows包括DirectX，其中一些具有升级能力。以下^(Below)是适用于不同版本Windows的最新DirectX版本。

• Windows 10  = DirectX 12。
  
• Windows Vista、7 和 8^{(Windows Vista, 7, and 8)}  = 最高到DirectX 11（Vista与DirectX 10一起发布）。
  
• 其他 Windows^{(Other Windows )}版本^(version) = 最高DirectX 9.0c，具体取决于Windows版本。

^(Video)需要DirectX 9^{(DirectX 9)}覆盖时，视频播放可能会失败

根据微软^(Microsoft)的说法，您可能会基于以下原因遇到此问题；

Some older video applications may depend on DirectX 9 overlays to work correctly. In Windows 8.1, there are rare scenarios in which the DirectX 9 overlay hardware is not available. In these situations, video playback doesn’t work.

In Windows 10, those scenarios are still rare, but they may occur more frequently than in Windows 8.1. This is especially true when your display options are set to a lower resolution than the native screen resolution.

要解决此问题，请将显示分辨率重置^{(reset the display resolution)}为本机屏幕分辨率。

但是，如果您的显示选项已设置为本机屏幕分辨率并且此问题继续出现，请退出所有打开的应用程序，然后重新启动您的视频应用程序。您还可以运行DirectX 诊断工具^{(DirectX Diagnostic Tool)}，看看是否对您有帮助。

Video playback fails when requiring DirectX 9 overlays in Windows 10

In today’s post, wе will provide a description of why video playback may fail when DirectX 9 overlays are required in Windows 10 – and then offer the workaround to resolve the issue. DirectX is a set of components in Windows that allows software, primarily and especially games, to work directly with your video and audio hardware.  Games that use DirectX can use multimedia accelerator features built-in to your hardware more efficiently which improves your overall multimedia experience.

Early versions of Microsoft Windows (XP and earlier) had multiple versions of DirectX that had to be installed separately. Later versions of Windows included DirectX with some having the ability to upgrade. Below are the latest versions of DirectX for the different versions of Windows.

• Windows 10 = DirectX 12.
  
• Windows Vista, 7, and 8 = Up to DirectX 11 (Vista released with DirectX 10).
  
• Other Windows version = Up to DirectX 9.0c depending on Windows version.

Video playback may fail when DirectX 9 overlays are required

According to Microsoft, you may encounter this issue based on the following reason;

Some older video applications may depend on DirectX 9 overlays to work correctly. In Windows 8.1, there are rare scenarios in which the DirectX 9 overlay hardware is not available. In these situations, video playback doesn’t work.

In Windows 10, those scenarios are still rare, but they may occur more frequently than in Windows 8.1. This is especially true when your display options are set to a lower resolution than the native screen resolution.

To work around this issue, reset the display resolution to the native screen resolution.

However, if your display options are already set to the native screen resolution and this issue continues to occur, exit all open applications and then restart your video application. You could also run the DirectX Diagnostic Tool and see if that helps you.
