An unsupported audio-video codec is a warning that pops up when the video player cannot play the audio or video of a file. If the issue is with the audio, you get an audio error, and with video, it’s a video error. If that’s what you are facing, here are three fixes to this unsupported codec issue in 2021.

Quick solution

The easiest fix is using the VLC Media Player on your Android phone. VLC comes with extended codecs to play files such as MKV, MOV, WMV etc.

Watch the video to see how VLC can fix the unsupported audio/video codec issues.

Quick fix for unsupported audio or video codec

What is a codec?

To understand why you get an unsupported audio/video codec error, you must understand what a codec is. According to Wikipedia, a codec is a program that encodes and decodes a digital data stream.

You might have seen the extensions like mp3, WMA etc., at the end of an audio file name and mp4, MKV, WMV, etc., on a video file name. These extensions are called containers, and these contain codecs.

The video and audio files take a considerable amount of space, so developers use the codecs to compress the file into a transferable source.

Each video player comes with the ability to play (installed) certain codecs. If a codec is not installed, your video player won’t play the audio or the video.

The default Android video player supports limited codecs, so many users get this warning while playing an unsupported file such as MKV.

Using VLC Media Player

Using VLC Media Player to fix the codec issue

The goal here is to play the video, and the solution is downloading VLC Media Player, a free and open-source media player. VLC Media Player comes with many codecs installed, making it more powerful than the default video player.

Other than VLC, there is MX Player, which also supports most formats, but in the test of VLC and MX Player, VLC won by playing ten out of ten videos.

Converting on Android

If you want to play the video in the default video player app, it is easiest to convert it. Try Video Converter or Full Video Converter. MP4 format videos tend to work fine on Android devices. There should also be an option to choose Android as a source.

If using some other app, be careful because some apps do not convert the audio file. In that case, the audio may not be supported.

Converting on PC

Converting on Android will fix the issue, but the Android converter may not be enough if the file is corrupted. In this case, the VLC Media player desktop can help.

VLC will fix the corrupted MP4 and MOV files, but you may need a different file repairing tool if you have a different file, such as MKV, FLV, etc.

VLC is a great converting tool, but it does not offer many options for editing the video. In that case, I suggest using a powerful tool such as HitFilm Express, which is free and offers some great editing tools.

Follow the tutorial to learn to convert using VLC Media Player.

Step: 01
Open VLC Media Player once downloaded and installed.

Step: 02
Go to Media on the top right, and then click on Save/Convert.

Step: 03
Add the video by clicking on the add button. You can add multiple videos by adding to the video list. You can also add a subtitle file to add to the converted file. Once all options look good, click on the Save/Convert button.

Step: 04
We need to select the profile for the video. New Android devices support full HD resolution easily, so we have plenty of options.

Even though we have plenty of options, we also have a separate option for Android devices. If the video is already HD quality (720p or 1080p), you can select the “Android HD” quality.

The Next button is greyed out until you do not choose the destination for the video. Click on Browse and choose a destination, and then click on Start.

Step: 05
Wait until the progress bar reaches the other side. Depending on the video, it will take some time.

    1. Uploading on Facebook is a different thing. There might be a problem with your connection or video format. Facebook app is also not good regarding uploading videos. Have you tried a computer to upload your video? You can try the lite version of Facebook to see that it can upload. Lastly, I can say is convert the video in video converter on Android and choose a different extension and then try. I hope it helps.

    Can you help me with a solution.

    1. That’s a different kind of issue. Have you tried playing the video on a computer? The first thing would be to check if there aren’t any problems with the recorded video. If the video is fine, then I’ll recommend converting the video. You can find some free converters online like Movie Maker or Hitfilm Express. Let me know if it helps. Thanks.

  5. I don’t want to download any app, I want to fix this problem because I can’t even film anything. Because of that codec I can’t film and reproduce the videos. So I want a solid solution to actually fix this problem without any other app, just the apps of my a20. Is that possible?

    1. You are thinking about changing root files. It’s not easy. The reason I have mentioned easy methods is to solve the problem ASAP. In your case, you’ll have to find the audio codec of the filming video and then install that codec in your device.

      By the way, why it’s causing while filming? Are you saying that after recording when you play there is no sound? Have you tried converting the video?

  6. Can someone help me on my issue on my android tv and black box(cable) or sky evo box.
