Android智能手机的最大优点是其大显示屏，让用户可以享受观看电影和视频的乐趣。随着时间的推移，Android智能手机变得越来越大。它们的屏幕分辨率和显示(resolution and display)效果显着提高。这些年来，出现了许多不同的音频和视频格式(audio and video formats)。它们是出于各种原因而创建的，例如提高媒体质量、优化文件大小等。但是，并非所有设备都与这些新格式兼容。每台设备都有自己支持的音频和视频格式集， (audio and video formats)Android也是如此。
有时，在尝试打开媒体文件时，您会在屏幕上收到一条错误消息。(error message)它说“无法播放音轨/视频。不支持的音频-视频编解码器”。此错误消息意味着您尝试打开的文件在(error message)Android上不受支持。文件也可能打开但无法正常工作。音频文件可能只是静音，而视频文件(video file)会显示黑屏。为了解决这个问题，我们需要了解编解码器实际上是什么。
修复 Android 上不支持的音频-视频编解码器问题(Fix Unsupported Audio-Video Codec Issues on Android)
什么是编解码器？(What is Codec?)
编解码器(Codec)是编解码器的简称。顾名思义，它是一种对数据进行编码和解码的手段，更具体地说是压缩数据。现在，音频剪辑或视频的原始源文件(source file)会占用大量空间。为了便于通过闪存驱动器、DVD、存储卡(memory card)等来源传输这些文件，开发人员使用编解码器压缩这些文件。
之前在源端压缩的文件需要在目标端解压缩，即在您的设备上播放视频时。如果您的设备没有适当的编解码器来解压缩文件，则会出现不支持的音频-视频代码错误。每种音频和视频格式(Every audio and video format)都有自己的编解码器。除非设备上存在适用于某些视频格式(video format)的正确编解码器，否则您将无法播放它。
什么是容器？(What is a Container?)
如果您注意到任何视频文件(video file)的名称，您会看到它是XYZ.mp4 或 XYZ.avi(XYZ.mp4 or XYZ.avi)等形式。这里 .mp4 和 .avi 代表文件的格式。这也称为容器。MP4、AVI、MKV、WebM等是视频文件(video file)的一些流行容器或格式。它们被称为容器，因为它们包含有关同步它们的音频和视频文件的信息。(audio and video files)
某些视频文件无法在 Android 上运行的原因是什么？(What is the reason behind some video files not working on Android?)
如前所述，视频文件(video file)需要适当的编解码器才能在某些设备上工作。这是因为实际文件在传输之前已被压缩和编码。为了播放视频，需要对其进行解压缩和解码。考虑到视频文件(video file)被锁定在其容器（AVI、MP4、MKV等）中，并且需要正确的编解码器来解锁它。现在，Android设备没有或不支持所有视频格式的编解码器。如果您要播放的视频属于此类别，那么您将无法在您的设备上运行它。
修复不支持的音频视频编解码器 Android(Fix Unsupported Audio Video Codec Android)
有几种方法可以解决Android上不支持的音频-视频编解码器问题(codec issue)。您可以使用具有支持格式扩展列表的其他媒体播放器，也可以使用转换器转换视频或音频文件(video or audio file)。让我们详细看看这些解决方案。
1.使用不同的媒体播放器(1. Use a Different Media Player)

Fix Unsupported Audio-Video Codec Issues on Android
The best thing about Android smartphones is their large display that allows users to enjoy watching movies and videos. Over the course of time, Android smartphones have become bigger and bettеr. Thеir screen resolution and display have improved significаntly. In all these years, a lоt of different audio and video formats have come up. They were created for various reasons, like to improve the quality of the media, to optimize the size of the file, etc. However, not all of the devices are compatible with these newer formats. Every device has its own set of supported audio and video formats and so doеs Androіd.
Sometimes, while trying to open a media file, you are hit with an error message on your screen. It says “Unable to play audio track/video. Unsupported audio-video codec”. This error message implies that the file you are trying to open is not supported on Android. It is also possible that the file might open but wouldn’t work properly. An audio file might just be mute and a video file would show a black screen. In order to deal with this problem, we need to understand what codec actually is.
Fix Unsupported Audio-Video Codec Issues on Android
What is Codec?
Codec is the short form of coder-decoder. As the name suggests, it is a means to encode and decode data, compressed data to be more specific. Now, the original source file for an audio clip or a video consumes a lot of space. In order to facilitate the transfer of these files via some source like a flash drive, DVD, memory card, etc., developers compress these files using a codec.
The file that was compressed earlier at the source needs to be decompressed at the destination, i.e. while playing the video on your device. If your device does not have the appropriate codec to decompress the file, then the unsupported audio-video codes error occurs. Every audio and video format has its own codec. Until and unless the proper codec for some video format is present on the device, you will not be able to play it.
What is a Container?
If you have noticed the name of any video file, you would see that it is in the form of XYZ.mp4 or XYZ.avi, etc. Here .mp4 and .avi represent the format of the file. This is also known as a container. MP4, AVI, MKV, WebM, etc. are some of the popular containers or formats for video files. They are called containers because they contain information about audio and video files that synchronizes them.
What is the reason behind some video files not working on Android?
As mentioned earlier, video files require a proper codec to work on some devices. This is because the actual file was compressed and encoded before being transferred. In order to play the video, it needs to be decompressed and decoded. Consider that the video file is locked in its container (AVI, MP4, MKV, etc.) and the proper codec is required to unlock it. Now, Android devices do not have or support codecs for all video formats. If the video that you wish to play falls under this category, then you wouldn’t be able to run it on your device.
Fix Unsupported Audio Video Codec Android
There are a couple of methods in which you can resolve the issue of unsupported audio-video codec issue on Android. You can either use a different media player that has an extended list of supported formats or convert the video or audio file using a converter. Let us take a look at these solutions in detail.
