Unsupported Audio/Video Codec is a warning which pops up when the video player can’t play the audio or the video of a file. For audio files, you get an audio error with mute audio, while in the video error the screen is black. If that’s the case with you, then follow this post to learn the three ways to fix unsupported audio/video codec issues on an Android device.

Simple Answer

The easiest fix is using the VLC Media Player app on your phone. If you want to learn more about VLC or wish to use the default video player, then follow the blog post.

Find your fix

There are many ways to fix the issue, but the post covers three. The first is the easiest one, but you can’t play the video in the default Android player. The last two are advanced and can take a long time, depending on the length of the video.

  1. Using VLC Media Player
  2. Converting the video on Android
  3. Converting the video on a PC

Why do I get this message?

To understand why you get unsupported audio/video codec, you must understand what a codec is.

What is a codec?

Before we get to the solution, let’s learn why we get this warning. You might have seen the extensions like MP3, WMA, etc., at the end of an audio file and MKV, WMV, etc., on a video file. These are called containers. A container contains 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 certain codecs installed to play different videos. If one or more codecs are missing in a video player, it will not be able to play the related format video. The default Android video player is limited regarding the codecs, so many users get this message when they try to play videos with extensions such as .mkv.

Using VLC Media Player to fix unsupported audio-video codec

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, we also have MX Player, which supports the majority of formats. MX Player free displays ads and a pro version is available which offers extended tools.

Using a video converter on Android

I have received messages about playing the videos in the default video player. There are many apps on the Google Play Store, which can convert videos straight in the phone. Try Full Video Converter or Video Converter to convert the video in MP4 (or select Android if device option is available) and choose MP3 or OGG as audio format and wait for the video to be converted. Some converters don’t convert the audio file, so you will have to be careful while choosing the converter.

Using a video converter on PC

These days it’s hard to find a free and relevant video converter. You will need a charging cable for your phone to open files on the PC. Once everything is ready, let’s download a video converter. Some of the free video converters are Freemake Video Converter and Any Video Converter. The free versions have limited features and may leave a watermark.  Before starting, make sure you understand what resolution your device supports. If your device is one of the latest, then 1080P would be fine.


Let’s go through the step by step process on how to convert for Android device. I’ll be using Freemake Video Converter, but the technique is the same for most of the converters.

Step 01: To begin, click on Video and then add the video you want to convert.

Step 02: Once the video has been added, click on “to MP4” in the footer. MP4 is one of the popular extensions, and most Android devices support it.

  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.

  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?
