我假设每个人都听说过Codec ，如果您还没有听说过，那么这篇文章将告诉您有关计算机上的(Codec)Codec(Codecs)的要点以及它们在 Windows PC 上安装的原因。
什么是编解码器
首先(First)说一下术语Codec是Coder 和 Decoder(Coder and Decoder)或者Compressor 和 Decompressor(Compressor and Decompressor)的组合。从技术上讲，编解码器是用于压缩或解压缩数字媒体文件（例如歌曲或视频）的软件。Windows Media Player和其他程序使用编解码器来播放和创建数字媒体文件。有多种用途的编解码器——例如，音频、视频、XviD、DVD等。
编解码器的工作原理
有时您的视频是以某种格式编码的，要么是为了压缩它，要么是为了使其轻量级。编解码器(Codec)压缩音频、视频和数字媒体。这些压缩的媒体文件是首选，因为它们比未压缩的文件占用的空间更小。MP3编码工具分析传入的源信号，将它们分解为数学模式，并将这些模式与存储在编码器本身中的心理声学模型进行比较。
编解码器也通过“解压缩” (Codec)MP3或任何其他数字媒体的压缩格式来完成相反的工作，以便它们可以在媒体播放器上播放。这称为解压缩(Uncompressing)。
Windows PC 上对Codec的需求
但是，有时您可能想要播放使用 Windows 或Player默认不包含的编解码器压缩的内容（例如，使用DivX 视频编解码器或Ogg Vorbis 音频编解码器压缩的文件）。要播放这种类型的媒体文件，您需要一个可以在 Internet 上免费下载的编解码器。推荐使用VLC(VLC)播放器，它可以播放比大多数其他媒体播放器更多类型的文件，并且完全免费。
选择正确的编解码器非常重要。坏人可以压缩恶意软件以及伪装成无害文件进入您的计算机的媒体文件。当您尝试在网络上观看视频时，媒体编解码器文件通常会访问您的计算机。
早些时候我谈到了编解码器(Codec)及其工作。人们发现很难理解他们的计算机上对Codec的需求，以解决有关(Codec)Codec的所有常见问题，我将在此处列出它们并给出答案
编解码器常见问题
为什么我的电脑需要编解码器？
视频或音频文件通常使用编解码器进行压缩，以减少占用的空间或通过Internet快速传输。要解压缩这些文件，需要在您的 PC 上安装编解码器
为什么我的媒体播放器不包含所有编解码器？
可悲的是，有许多编解码器可用，并且仍在继续出现。应用程序使用不同的编解码器在互联网上传输音频、视频。媒体播放器可能不包含所有这些编解码器。
我在哪里可以下载编解码器？
互联网上有来自多个供应商的编解码器，可以免费下载。流行的是Klite 编解码器(Klite Codec)包。
哪个媒体播放器支持几乎所有编解码器？
WMP12 和VLC等流行的媒体播放器为许多编解码器提供扩展支持。
编解码器和文件格式是否相同？
不，有时它们具有相同的名称 - 例如，Windows Media Audio包含使用Windows Media Audio编解码器压缩的数据。但是，诸如音频视频交错(Audio Video Interleaved)( AVI ) 之类的文件格式可以包含由多种不同编解码器中的任何一种压缩的数据，包括MPEG-2、DivX或XviD编解码器。
我如何知道计算机上已安装的编解码器？
您可以检查(check the installed codecs)Windows 计算机上已安装的编解码器。
- 启动Windows Media Player，然后单击“帮助”
- 单击“关于 Windows 媒体播放器”。
- 点击“技术支持信息”
然后它会列出您 PC 上安装的所有编解码器。
如何确定用于压缩文件的编解码器？
这可以使用编解码器识别工具(Codec Identification Tools)来完成。
提示(TIP)：在此处下载 Windows 10 编解码器(Download Windows 10 Codecs)。
我安装了缺少的编解码器，但仍然无法播放文件。
永远记住，编解码器分别可用于 32 位或 64 位操作系统。如果您运行的是 64 位操作系统，请确保安装 64 位编解码器。(Make)
我希望我已经涵盖了几乎所有关于编解码器的常见问题解答，如果您仍然有一些问题，请在下面的评论部分中列出它们。(I hope I have covered almost all FAQ’s on codecs if you still have some questions do list them in the comment section below.)
额外提示(Bonus Tip)：编解码器调整工具可以帮助您管理、检测和删除损坏的编解码器(Codecs)和过滤器(Filters)。
What is a Codec - Overview, Features, Download, FAQ
I assume everyone hеard abоυt a Codec, and if you haven’t then this post will tell you key points regarding Codecs on your computer and the reason as to what they are installed on your Windows PC.
What is a Codec
First of all, talking about the terminology Codec is a combination of Coder and Decoder or Compressor and Decompressor. And technically a codec is software that is used to compress or decompress a digital media file, such as a song or video. Windows Media Player and other programs use codecs to play and create digital media files. There are codecs for many purposes – for example, audio, video, XviD, DVD, etc.
How Codecs work
There are times when you have a video that is coded in some format, either to compress it or to make it lightweight. Codec compresses audio, video, and digital media. And these compressed media files are preferred as they occupy a smaller space than uncompressed ones. MP3 encoding tools analyze incoming source signals, break them down into mathematical patterns, and compare these patterns to psycho-acoustic models stored in the encoder itself.
The Codec does the reverse job as well by ‘uncompressing’ the compressed format of MP3 or any other digital media so that they can be played on the media player. This is called Uncompressing.
The need for Codec on your Windows PC
There might be times, however, when you want to play content that was compressed with a codec that Windows or the Player doesn’t include by default (for example, a file compressed with the DivX video codec or the Ogg Vorbis audio codec). To play this type of media file, you need a codec that can be downloaded for free on the internet. VLC player is recommended, It can play many more types of files than most other media players and it is completely free.
Choosing the right codec matters a lot. Bad people can compress malicious software along with media files that get onto your computer disguised as a harmless file. Media-Codec files often gain access to your computer when you try to watch videos on the web.
Earlier I had talked about Codec and its working. People find it hard to understand the need for Codec on their computer, to address all frequently asked questions regarding Codec, I will list them here and will give answers to that as well
Codecs FAQ
Why do I need a codec on my computer?
A video or audio file is usually compressed using a codec to reduce the space it occupies or to quickly transfer it across the Internet. To decompress these files it requires codec to be installed on your PC
Why does my media player not contain all codecs?
Sadly there are many codecs available and still continue to come up. Applications use different codecs to stream audio, video over the internet. The media player may not contain all these codecs.
Where can I download Codecs?
There are codecs from multiple vendors on the internet that can be downloaded for free. The popular one is the Klite Codec pack.
Which media player offers support for almost all codecs?
Popular media players such as WMP12 and VLC offers extended support for many codecs.
Is codec and file format the same?
No, sometimes they have the same name – for example, Windows Media Audio contains data that is compressed by using the Windows Media Audio codec. However, a file format such as Audio Video Interleaved (AVI) can contain data that is compressed by any of a number of different codecs, including the MPEG-2, DivX, or XviD codecs.
How do I know about the installed codecs on my computer?
You can check the installed codecs on your Windows computer.
- Launch Windows Media Player and then click “Help”
- Click “About Windows Media Player”.
- Click “Technical Support Information”
It then lists all codecs installed on your PC.
How to determine which codec was used to compress the file?
This can be done using Codec Identification Tools.
TIP: Download Windows 10 Codecs here.
I installed missing codecs and still cannot play the files.
Always remember that codecs are available for 32-bit or 64-bit operating systems separately. Make sure you install the 64-bit codec if you are running 64-bit operating system.
I hope I have covered almost all FAQ’s on codecs if you still have some questions do list them in the comment section below.
Bonus Tip: The Codec Tweak Tool can help you manage, detect, and remove broken Codecs and Filters.
