Unsupported Audio Video Codec

Unsupported audio-video codec is a warning which pops up when the video player isn’t able to play the audio or the 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, then here are three fixes to this unsupported codec issue in 2020.

Quick solution

The easiest fix is using the VLC Media Player or MX Player on your phone. If you want to learn more about those apps or wish to play the video in the default video player, then read along. Watch the video to see how VLC can fix unsupported audio/video codec issue.

What is a codec?

According to Wikipedia, a codec is a program which encodes and decodes a digital data stream. To understand why you get unsupported audio/video codec, you must understand what a codec is. You might have seen the extensions like MP3, WMA, etc., at the end of an audio file name and 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 be able to 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

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

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



Converting on Android

You may want to play the video in the default video player for some reason. The easiest way is to convert the video. Try Video Converter to convert the video. 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 if the file is corrupted, then the Android converter may not be enough. In this case, VLC Media player can help. VLC will fix the corrupted MP4 and MOV files, but if you have a different file such as MKV, FLV etc., then you may need a different file repairing tool.

There are plenty of video converters out there, but most of them leave a watermark or limit on the video quality. Just like on Android and iOS, VLC software is a powerful tool. Alongside playing videos, it can convert the videos into different formats.

VLC is a great converting tool, but when it comes to editing the video, it does not offer any options. In that case, I would suggest using a powerful tool such as HitFilm Express which is free and offers some great editing tools. Please note that HitFilm Express is a powerful tool, and it requires a good computer to run at its best. Anyway, 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
The next step is important. 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 in HD quality (720p or 1080p) then 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.

Wait until the progress bar reaches to the other side. Depending on the video it will take some time.

  1. Hi,
    Quick help request- I recorded audio with saramonic sr-wm4c on sony a7iii camera and the audio output is not playing in my youtube video. How to fix this? it works fine on desktop but not on android.

  2. Converting is a good option but most of the software these days ask you to pay. Anyway, I’ll try that Video Converter app on Android.

    1. My phone has show the vp9 vedios encoding format .my phone is huwawei y9prime 2019.i had some folders after then i show that error .how can i get it again

  3. Hi i have the same issue i downloaded the vcl it works the video plays but why cant i upload it on Facebook?? Im using Samsung Galaxy a6+, when i click upload on Facebook i cant click the video to be uploaded

    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.

  4. Hi M K,

    Hope you are doing well

    Seek your help to solve the issue faced by me.

    I have used my Gimbal and recorded video, while playing the same i understand audio is playing and video is not playing in the mobile.

    Further i tried playing in TV initially audio was playing and further to that video was playing at the end.

    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?
