在Windows Media Player、Xbox One应用程序、电影^(Movies)和电视应用程序或任何视频播放器^{(Video Player)}中播放视频文件时，您可能会看到一条错误消息，指出视频无法解码^{(Video could not be decoded)}。该错误会阻止用户播放任何视频或编辑MP4文件。多种原因可能是造成这种情况的原因。我们将介绍一些可以帮助您解决此问题的方法。

视频^(Video)无法在 Windows 11/10 上解码

在Windows中看到不受支持的^(Windows)视频编解码器^{(video codec)}或格式错误可能很烦人，因为这些错误不允许您播放或编辑视频。不过，您可以尝试一些解决方法来帮助您解决视频无法解码^{(Video could not be decoded)}的问题。

1. 禁用并重新启用软件
2. 设置正确的音频设备。
3. 转换视频文件格式。
4. 使用注册表黑客。
5. 更新您的显示驱动程序
6. 在不同的媒体播放器^{(Media Player)}上播放视频。

一个视频文件通常包含 2 个组件。

• 编解码器^{(A codec)}——编码或解码视频数据所必需的。^{(Required to encode or decode)}
• 容器^{(A container)}– 包含文件元数据的文件格式。

如果您选择的媒体播放器不支持视频格式^{(media player of your choice doesn’t support the video format)}或编解码器，它将不会播放视频文件。

1]禁用^(Disable)并重新启用软件

如果您在Windows MediaPlayer上遇到此问题，请执行此操作。

如果您在使用Windows Media Player时遇到问题，您需要使用 Windows 功能面板^{(use the Windows Features panel)}删除该软件，然后重新添加。这是因为，该程序是内置的Windows 10组件。

• 在Windows 10搜索^(Search)框中键入打开或关闭 Windows 功能，然后^{(turn windows features on or off)}按 Enter^(Enter)。
• 接下来，向下滚动到Media Features。
• 点击它旁边的“+”按钮以展开菜单。
• 取消选中标记为Windows Media Player的框。
• 选择确定^(OK)删除Windows Media Player。

重启你的电脑。

• 返回到Windows 功能^{(Windows Features)}框。
• 选中Windows Media Player^{(Windows Media Player)}旁边的框。
• 选择确定^{(Select OK)}以重新安装Windows Media Player。

这将再次启用 Windows Media Player。

如果您在UWP Microsoft Store^{(UWP Microsoft Store)}应用上遇到此问题，请修复或重置它^{(Repair or Reset it)}。

如果您在使用经典视频播放器软件时遇到此问题，您可以重新安装它。

2]设置正确的音频设备

您还可以检查Windows Media Player是否使用了错误的音频输出设备。前往WMP 选项^(Options)。为此，请转到“工具^(Tools)”菜单。如果您没有看到菜单栏，请使用Ctrl+M快捷键。

选择选项^(Options)并切换到设备^(Devices)选项卡。

接下来，在“设备^(Devices)”部分下，选择“扬声器^(Speakers)”并选择“属性^(Properties)”按钮。

现在，选择相同的播放设备，当您单击扬声器图标时，您会在系统托盘下找到。

3]转换视频文件格式

您可以选择^{(choose a different format)}与您的播放器兼容的其他格式。

在许多情况下，已发现AVI、MP4或MOV文件与大多数媒体播放器和视频编辑软件^{(video editing software)}兼容。

相关^(Related)：将AVI、MKV、AVCHD、MOV转换为 MP4，反之亦然。

4]使用注册表黑客

Windows Media Player通常依赖一组特定的条目来播放音频和视频文件。这些条目可以在注册表编辑器^{(Registry Editor)}下找到。您可以检查这些条目中的值是否正确或已更改。我们建议您在继续之前备份Windows 注册表。^{(Windows Registry)}请执行下列操作。

Press Win+R打开“运行”^(Run)对话框。

在“运行”^(Run)对话框的“空^(Empty)”字段中，键入 regedit 并选择“确定”。

错误地更改注册表编辑器^{(Registry Editor)}可能会产生严重后果。在继续之前创建一个系统还原点。^{(Create a System Restore point)}

导航到以下路径地址 -

HKEY_CLASSES_ROOT\CLSID\{da4e3da0-d07d-11d0-bd50-00a0c911ce86}\Instance\{083863F1-70DE-11d0-BD40-00A0C911CE86}

在左侧导航窗格中，选择：

 {083863F1-70DE-11d0-BD40-00A0C911CE86}

在这里，请确保以下注册表项包含下面给出的值。

• CLSID —{083863F1-70DE-11d0-BD40-00A0C911CE86}
• FriendlyName - DirectShow 过滤器
• 优点 — 00600000

如果可以看到注册表项中的某些不同值，请将其更改为上面列出的值。

只需^(Simply)右键单击要修改的条目，选择修改^(Modify)选项，然后将值更改为上面显示的值。

完成后选择确定。

5]更新您的显示驱动程序

更新您的图形或显示驱动程序^{(Updating your Graphics or Display driver)}也很有帮助。所以试试看。

6]在不同的媒体播放器上^{(Media Player)}播放视频^(Play)

最后，如果上述所有方法都未能产生所需的结果，您可以切换到不同的媒体播放器^{(different Media Player)}，如VLC Player。

希望有所帮助。^{(Hope something help.)}

Video could not be decoded on Windows 11/10

While plaуing a video file in Wіndows Media Plауer, Xbox One app, Movies and TV app, or any Video Player you could see an error message sаying Video could not be decoded. The error prevents users from playing any videos or editing MP4 files. Multiple reasons could be responsible for it. We’ll look at some of the methods that could help you fix this problem.

Video could not be decoded on Windows 11/10

It can be annoying to see the unsupported video codec or format errors in Windows as these errors don’t let you play videos or edit them. Nevertheless, you can try a few workarounds to help you get past the Video could not be decoded problem.

1. Disable and re-enable the software
2. Set Correct Audio Device.
3. Convert the video file format.
4. Use the Registry hack.
5. Update your Display Driver
6. Play the video on a different Media Player.

A video file in general comprises 2 components.

• A codec – Required to encode or decode the video data.
• A container – A file format containing the file metadata.

If the media player of your choice doesn’t support the video format or codec, it won’t play the video file.

1] Disable and re-enable the software

If you face this issue on Windows MediaPlayer, do this.

If you are experiencing a problem with the Windows Media Player, you’ll need to use the Windows Features panel to remove the software and then, add it back. This is because, the program is a built-in Windows 10 component.

• Type turn windows features on or off in the Windows 10 Search box and hit Enter.
• Next, scroll down to Media Features.
• Tap the ‘+’ button next to it to expand the menu.
• Uncheck the box marked against Windows Media Player.
• Select OK to remove the Windows Media Player.

Restart your computer.

• Go back to the Windows Features box.
• Check the box next to Windows Media Player.
• Select OK to reinstall the Windows Media Player.

This will again enable the Windows Media Player.

If you face this issue on a UWP Microsoft Store app, Repair or Reset it.

If you face this issue with your classic video player software, you could reinstall it.

2] Set the correct Audio Device

You can also check if the Windows Media Player is using the wrong audio output device. Head to the WMP Options. For this, go to the Tools menu. If you don’t see the menu bar use the Ctrl+M shortcut.

Select Options and switch to the Devices tab.

Next, under the Devices section, choose Speakers and select the Properties button.

Now, choose the same playback device, you find under the system tray when you click the speaker icon.

3] Convert the video file format

You can choose a different format that is compatible with your player.

In many cases, it has been found that AVI, MP4 or MOV files are compatible with most media players and video editing software.

Related: Convert AVI, MKV, AVCHD, MOV to MP4 and vice versa.

4] Use the Registry hack

The Windows Media Player often relies on a set of specific entries to play audio and video files. These entries can be found under the Registry Editor. You can check if the values within these entries are correct or have been changed. We recommend that you make a backup of the Windows Registry before going ahead. Do the following.

Press Win+R in combination to open the Run dialog box.

In the Empty field of the Run dialog box, type regedit and select OK.

Making changes to the Registry Editor incorrectly can have serious consequences. Create a System Restore point before proceeding further.

Navigate to the following path address –

HKEY_CLASSES_ROOT\CLSID\{da4e3da0-d07d-11d0-bd50-00a0c911ce86}\Instance\{083863F1-70DE-11d0-BD40-00A0C911CE86}

On the left-side navigation pane, select:

 {083863F1-70DE-11d0-BD40-00A0C911CE86}

Here, make sure the following registry entries contain the values given below.

• CLSID — {083863F1-70DE-11d0-BD40-00A0C911CE86}
• FriendlyName — DirectShow Filters
• Merit — 00600000

If some different value in a registry entry is visible, change it to the ones listed above.

Simply, right-click the entry to be modified, choose Modify option, and change the values to the ones shown above.

Select OK, when done.

5] Update your Display Driver

Updating your Graphics or Display driver has also been known to help. So try that and see.

6] Play the video on a different Media Player

Lastly, if all the above methods fail to yield the desired results, you can switch to a different Media Player like VLC Player.

Hope something help.
