编解码器(Codec)一词是压缩器和解压缩器的首字母缩写。编解码器(Codecs)是一种压缩视频并随后帮助对其进行解码的程序。因此，如果您收到错误消息 —需要编解码器才能播放此文件(A codec is required to play this file)；这意味着您没有编解码器来解码和播放计算机上的文件。

您可以看到的其他类似消息是：
- Windows Media Player 无法播放该文件，因为您的计算机上未安装所需的视频编解码器。
- Windows Media Player无法播放、刻录、翻录或同步文件，因为您的计算机上未安装所需的音频编解码器。
- 文件格式无效。
播放此文件需要编解码器
将其视为可以减小视频文件大小的程序，以便最终用户可以更快地下载它。之后(Later)，消费者可以解码文件并在他的电脑上播放。由于有许多编解码器，除非您有正确的编解码器，否则您无法播放文件。
此外，还有很多场景。有时视频播放时没有音频，有时播放的声音是空白屏幕。那么当视频无法播放或无法打开时该怎么办。我们需要正确的编解码器。你们中的一些人可能已经在Windows Media Player中看到了这一点。
但是我们如何决定需要哪个编解码器呢？如何检查已安装的编解码器(check the installed codecs)？除非播放器给出特定名称或您使用CodecInstaller，否则很难猜测。因此，在这篇文章中，我们列出了一些流行的编解码器和播放器，您可以使用它们来播放任何文件。
如何在 Windows 10 上下载和安装编解码器
您可以将Windows Media Player配置为自动下载编解码器。为此，请打开Tools > Options并单击播放器(Player)选项卡。选中自动下载编解码器(Download codecs automatically)复选框，然后单击确定。
您也可以手动下载和安装编解码器。要安装编解码器，您必须在其安装程序设置文件上单击。要卸载编解码器，您可以从控制面板(Control Panel)执行此操作。Microsoft Store中提供了一些编解码器。要卸载它们，请在“开始”菜单(Start Menu)应用程序列表中查找该应用程序并从此处卸载它们。
这是您可以在计算机上下载的编解码器列表。(Codecs)如果这不起作用，您可以选择一些喜欢的播放器，其中包括许多编解码器并播放几乎任何文件。

A codec is required to play this file - Download & Install Codec
The word Codec is an acronym of the words compressor and decompressor. Codecs are a program that compresses a video and later helps to decode it. So if you receive an error — A codec is required to play this file; it means you don’t have the codec to decode and play the file on your computer.

A codec is required to play this file
Think of it as a program which can reduce the size of a video file so the end-user can download it faster. Later, the consumer can decode the file and play it on his computer. Since there are many codecs, unless you have the right codec, you cannot play the file.
Further, there are many scenarios. Sometimes the video plays without audio, occasionally its the sound which plays with a blank screen. So what can do when the video doesn’t play, or it doesn’t open. We need the right codec. Some of you might have seen this with Windows Media Player.
But then how do we decide which codec is required? How can you check the installed codecs? It’s hard to guess unless the player gives out a specific name or you use the CodecInstaller. So in this post, we are listing some popular codecs and players which you can use to play any files.
