"I have successfully downloaded the WaterMan movie from Netflix and am eager to learn how Gunner saves his mother. But this video gets stuck on an error saying unsupported video codec. How can I fix codec not supported problem?"

Has this ever happened to you? You are all eyes to watch a video but the video cannot play normally; instead, it shows the error message video codec not supported, or audio codec not supported if the problem lies in audio.

So, What Is Codec?

Codec, being the abbreviation of coder-decoder, is an important program that runs behind every media file. As you might have guessed, video files have video codec and audio files have audio codec.

Video codec is responsible for compressing your videos into various file formats such as AVI, MP4, MKV, MOV, etc., and it also decompresses those video files when you need to play the video.

Why Did I Get Unsupported Codec or Format Error?

As we know, media players are not almighty and they support limited video codecs. So the main reason for this error is that the codec of your media file is not supported by the player.

Another possible reason is that the video file format is not supported. File format is also referred to as container, which is responsible for synchronizing audio and video.

But don't worry much if you have also encountered the unsupported video codec issue. Here are three fixes to eradicate such errors and let you get back to watch your latest downloaded movie from Netflix.

How to Fix Video and Audio Codec Not Supported Error?

Mostly, we'll need to deal with either the video player, or the codec itself when you get an unsupported video format error. Check out these available solutions for a quick fix.

Solution 1: Try a Different Video Player

Usually, the default media player has some limitations on supported video or audio codecs, that's why we get video codec not supported error. QuickTime media player, for example, doesn't support formats like MKV and WEBM. Nonetheless, Windows Media Player can't play FLAC or FLV files. So if the player is giving a video codec error, you can try to play your video on a different media player that supports it.

It's better to opt for a free and open-source multimedia player that supports the most common output codecs. As far as I know, VLC player is the most renowned video player in the market now, whether you are going to use it on Windows PC or Android, or Mac.

MX Player is another good choice for playing media files. Just like VLC player, it supports a wide range of video formats and video codecs, which makes it better than the default player.

We can also download and install certain codec packs from the web manually; such packs contain a wide range of video and audio codecs that different file types require, so most files will play without any errors. Here are some commonly required codec packs for various audios and videos.

  • Advanced codecs: This is a free audio and video code package that comes with a full suite of codecs. It comes both in 32-bit and 64-bit app.

FAQ on Codecs: Everything You Want to Know

After fixing the video or audio codec not supported on Windows or Android issue, users often seek answers to various questions related to video codecs. Here are answers to some frequently asked questions.

1. How do I choose a video codec?

It is advisable to choose a video codec that is not only compatible with your media player, but also of high quality. The video codec you choose will significantly affect your video's size and quality. Just ensure it is less compressed and has a higher bit-depth.

2. Why can't I play a file at work that I can play at home?

Perhaps your computer at workplace does not have the same codecs installed as the one you use at home. It, therefore, doesn't support that particular video or audio file that you want to play. You should convert the video file format or try to play your video file using another media player other than your computer's default media player.
