演示文稿已成为全球学校和办公室沟通和共享信息的重要工具。Microsoft PowerPoint允许您创建具有视觉吸引力的演示文稿(create visually appealing presentations)，其中包含各种多媒体元素，例如视频和音频。
但是，您可能会在PowerPoint(PowerPoint)中遇到“无法播放媒体”错误，从而导致视频播放问题并妨碍演示文稿的顺利交付。如果您想解决此问题，请按照以下步骤操作。
PowerPoint中出现“无法播放媒体”错误的原因是什么？
当PowerPoint(PowerPoint)无法找到或播放您在演示文稿中插入的媒体文件时，通常会出现PowerPoint中的“无法播放媒体”错误（或“找不到媒体”错误） 。
发生这种情况的原因有多种。文件可能丢失、移动、重命名或从其原始位置删除，或者可能以某种方式损坏或损坏。您还可能链接到无法再访问的外部源（例如网站）。
但是，并非每个文件都与PowerPoint(PowerPoint)兼容。文件格式不正确或太大而PowerPoint无法使用的文件将无法加载。
根据错误原因，您可能会在屏幕上看到不同的消息，例如不支持的文件类型、需要音频编解码器来播放文件、发生网络错误或无法播放指定的文件。
要修复此错误，您需要按照以下步骤确定原因并应用适当的解决方案。
检查媒体文件(Media File)的位置(Location)和名称(Name)
最简单的解决方案之一是检查在演示文稿中插入的媒体文件是否仍位于其原始位置并且具有相同的名称。如果在将媒体文件插入PowerPoint后移动、重命名或删除该媒体文件，PowerPoint可能无法找到它，并会向您显示错误消息。
然而，这一切都取决于PowerPoint文件的保存方式。默认情况下，PowerPoint可能会尝试将媒体文件嵌入到PowerPoint文件本身中，这样可以更轻松地随文件移动媒体资源。但是，如果您仅添加了文件的链接，则需要将文件的链接更新到新位置。
如果您想更新链接，请按照下列步骤操作：
- 打开PowerPoint并按File > Info。
- 如果您有任何带有链接的媒体文件（因此它们不会嵌入到文件本身中），您将看到“优化媒体兼容性”下列出的“查看链接”选项(View Links)- 选择(Optimize Media Compatibility—select)此选项以继续。
- 在Audio/Video Options对话框中，选择您的媒体文件，然后按“更改源”(Change Source)。
- 浏览(Browse)到文件的新位置和名称，然后按“打开”(Open)。
- (Press Update)完成后按“立即更新”，然后按“关闭”更新链接。(Close)
使用 PowerPoint 媒体兼容模式(Use PowerPoint Media Compatibility Mode)
修复PowerPoint中“无法播放媒体”错误的另一种可能的解决方案是使用PowerPoint中的媒体兼容模式。
此模式允许您优化演示文稿以与旧版本的PowerPoint或不同设备兼容。它还可以帮助您解决视频播放和转换方面的一些问题。要在PowerPoint(PowerPoint)中使用媒体兼容模式，请按照以下步骤操作。
- 打开PowerPoint并按File > Info。
- 按(Press Check)“检查演示”(Inspect Presentation)部分下的“检查问题”(Issues)。
- 在下拉菜单中，按“检查兼容性”(Check Compatibility)并等待PowerPoint扫描演示文稿是否存在潜在的兼容性问题。
- 在“兼容性报告”(Compatibility Report)对话框中，查找与媒体文件相关的任何问题并选中它们旁边的框。
- 手动修复(Fix)问题，或者如果您可以使用该选项，请按“修复”(Fix)并等待PowerPoint自动修复问题。
- 保存演示文稿并查看媒体文件播放时是否没有任何错误。
请注意，使用媒体兼容模式可能会更改演示文稿的某些方面，例如媒体文件的格式、质量或大小。请(Make)确保在继续之前备份文件的副本，以便之后可以恢复任何更改。
使用 VLC 转换媒体文件
另一种可能的解决方案是转换或压缩在演示文稿中插入的媒体文件。PowerPoint 可能无法播放某些类型的媒体文件或播放太大或高分辨率的文件。这可能会导致兼容性问题并导致错误消息。
要解决此问题，您需要将媒体文件转换为PowerPoint(PowerPoint)支持的格式，或者对其进行压缩以减小其大小和分辨率。VLC Media Player是一种可以转换和压缩媒体文件的工具。
要使用VLC Media Player(VLC Media Player)转换媒体文件，请按照下列步骤操作：
- (Download and install VLC Media Player)从其官方网站
下载并安装 VLC Media Player 。
- 打开VLC 媒体播放器(VLC Media Player)并按Media > Convert/Save。
- 在“打开媒体”(Media)对话框中，按“添加”(Add)并选择要转换的媒体文件，然后按Convert/Save。
- 选择您想要的输出格式——这将决定文件大小。例如，您可以为视频文件选择Video – H.264 + MP3 ( MP4 )，或者为音频文件选择音频 – MP3 。(Audio – MP3)您还可以选择视频或音频格式，例如MKV、WAV或MP4。
- 选择浏览(Select Browse)并选择目标文件夹和转换文件的名称。
- 按开始(Press Start)并等待转换完成。
文件转换后，您可以将新文件插入到PowerPoint演示文稿中。
将媒体文件(Media File)嵌入到您的(Your)演示文稿
中
另一种可能的解决方案是将媒体文件嵌入到 PowerPoint 演示文稿中，(embed the media file in your PowerPoint presentation)而不是链接到它。正如我们已经提到的，链接到媒体文件意味着PowerPoint会在您每次播放文件时在其原始位置查找该文件。
嵌入媒体文件意味着PowerPoint将在演示文稿文件中存储该文件的副本。这可以防止出现“无法播放媒体”错误，因为PowerPoint始终可以访问该文件，无论其位置或可用性如何。
但是，嵌入媒体文件也会显着增加演示文稿文件的大小，因此您需要注意嵌入的媒体文件的数量和大小。要将媒体文件嵌入到PowerPoint演示文稿中，请按照以下步骤操作。
- 在PowerPoint中，转到要插入媒体文件的幻灯片，然后选择Insert > Media > Video > “此设备”(Device)。
- 浏览(Browse)到媒体文件的位置并选择它。
- 按(Press)“插入”(Insert)按钮- 这将自动将其嵌入到您的演示文稿中。如果此选项不可用，请按演示文稿旁边的下拉箭头，然后选择“在此处插入” 。(Insert)
插入文件后，调整大小并将其放置到演示文稿中的正确位置。对要在演示文稿中使用的任何其他视频文件
重复这些步骤。(Repeat)
在 PowerPoint 中管理媒体
PowerPoint中的“无法播放媒体”错误可能令人烦恼且令人沮丧，但通常可以修复。您只需检查媒体文件的位置和名称，对其进行转换或压缩，或者将其嵌入到演示文稿中。您还可以尝试使用PowerPoint的多媒体(multimedia)兼容模式来帮助其在其他电脑上加载。
如果所有其他方法都失败，您还可以将 PowerPoint 演示文稿转换为视频(convert your PowerPoint presentation into a video)并在另一台设备上播放。重新启动后丢失了对PowerPoint演示文稿的更改？不要忘记恢复未保存的演示文稿(recover your unsaved presentations)以恢复更改。
How to Fix “Cannot Play Media” Error in PowerPoint
Preѕentations have become a vital tool for communication and sharing information in schoоls and offices worldwide. Microsoft PowerРoіnt allows you to create visually appealing presentations that include various multimedia elements, such as video and audio.
However, you might encounter “cannot play media” errors in PowerPoint, causing video playback issues and preventing the smooth delivery of your presentation. If you want to resolve this problem, follow the steps below.
What Causes the “Cannot Play Media” Error in PowerPoint?
The “cannot play media” error in PowerPoint (or “media not found” error) usually occurs when PowerPoint cannot find or play the media file that you’ve inserted in your presentation.
This can happen for several reasons. The file might be missing, moved, renamed, or deleted from its original location, or it could have become corrupted or damaged in some way. You could also have linked to an external source (such as a website) that’s no longer accessible.
However, not every file is compatible with PowerPoint. Files that don’t have the correct file format, or are too large for PowerPoint to use, won’t load.
Depending on the cause of the error, you may see different messages on your screen, such as no supported file type, an audio codec is needed to play the file, a network error has occurred, or the specified file can’t be played.
To fix this error, you need to identify the cause and apply the appropriate solution using the steps below.
Check the Location and Name of the Media File
One of the simplest solutions is to check if the media file that you inserted in your presentation is still in its original location and has the same name. If you moved, renamed, or deleted the media file after inserting it in PowerPoint, PowerPoint may not be able to find it and will show you the error message.
However, this all depends on how the PowerPoint file has been saved. By default, PowerPoint will likely try to embed media files into the PowerPoint file itself—this makes it easier to move media assets with the file. However, if you’ve only added a link to the file, you’ll need to update the link to the file to the new location.
If you want to update the link, follow these steps:
- Open PowerPoint and press File > Info.
- If you have any media files with links (so they aren’t embedded into the file itself), you’ll see a View Links option listed under Optimize Media Compatibility—select this to proceed.
- In the Audio/Video Options dialog box, select your media file and press Change Source.
- Browse to the new location and name of the file and press Open.
- Press Update Now and then Close to update your links when you’re finished.
Use PowerPoint Media Compatibility Mode
Another possible solution to fix the “cannot play media” error in PowerPoint is to use the media compatibility mode in PowerPoint.
This mode allows you to optimize your presentation for compatibility with older versions of PowerPoint or different devices. It can also help you resolve some issues with video playback and conversion. To use the media compatibility mode in PowerPoint, follow the steps below.
- Open PowerPoint and press File > Info.
- Press Check for Issues under the Inspect Presentation section.
- In the drop-down menu, press Check Compatibility and wait for PowerPoint to scan your presentation for potential compatibility issues.
- In the Compatibility Report dialog box, look for any issues related to media files and check the boxes next to them.
- Fix the problems manually or, if the option is available to you, press Fix and wait for PowerPoint to fix the issues automatically.
- Save your presentation and see if the media files play without any error.
Note that using the media compatibility mode may change some aspects of your presentation, such as the format, quality, or size of your media files. Make sure to back up a copy of your file before you proceed so that you can restore any changes afterward.
Convert the Media Files Using VLC
Another possible solution is to convert or compress the media file that you inserted in your presentation. PowerPoint may not be able to play certain types of media files or play files that are too large or have a high resolution. This can cause compatibility issues and lead to the error message.
To fix this, you need to either convert the media file to a format that is supported by PowerPoint or compress it to reduce its size and resolution. One possible tool that allows you to convert and compress a media file is VLC Media Player.
To convert a media file using VLC Media Player, follow these steps:
- Download and install VLC Media Player from its official website.
- Open VLC Media Player and press Media > Convert/Save.
- In the Open Media dialog box, press Add and select the media file that you want to convert, then press Convert/Save.
- Choose the output format that you want—this will determine the file size. For example, you can choose Video – H.264 + MP3 (MP4) for video files or Audio – MP3 for audio files. You can also choose video or audio formats such as MKV, WAV or MP4.
- Select Browse and choose the destination folder and name for the converted file.
- Press Start and wait for the conversion to finish.
Once the file is converted, you can insert the new file into your PowerPoint presentation.
Embed the Media File in Your Presentation
Another possible solution is to embed the media file in your PowerPoint presentation instead of linking to it. As we’ve already mentioned, linking to a media file means that PowerPoint will look for the file in its original location every time you play it.
Embedding a media file means that PowerPoint will instead store a copy of the file within your presentation file. This can prevent the “cannot play media” error from occurring because PowerPoint will always have access to the file regardless of its location or availability.
However, embedding a media file can also increase the size of your presentation file significantly, so you need to be careful about how many and how large media files you embed. To embed a media file in your PowerPoint presentation, follow these steps.
- In PowerPoint, go to the slide where you want to insert the media file and select Insert > Media > Video > This Device.
- Browse to the location of the media file and select it.
- Press the Insert button—this will automatically embed it into your presentation. If this isn’t available, press the dropdown arrow next to your presentation and choose Insert there instead.
Once the file is inserted, resize and place it into the correct position in your presentation. Repeat these steps for any other video files you want to use in your presentation.
Managing Media in PowerPoint
The “cannot play media” error in PowerPoint can be annoying and frustrating, but it can usually be fixed. You’ll just need to check the location and name of the media file, convert or compress it, or embed it in your presentation. You can also try using PowerPoint’s multimedia compatibility mode to help it load on other PCs.
If all else fails, you can also convert your PowerPoint presentation into a video and play it on another device. Lost the changes to your PowerPoint presentation after a restart? Don’t forget to recover your unsaved presentations to recover the changes.
