An unsupported audio-video codec is an error 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, you get 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.

    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.

          1. Must be permission issues. Have you granted the permissions?

            Other suggestions are:

            Force closing apps and then restarting
            Restarting the phone
            Checking your SD card if using SD card

  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?

  6. Can someone help me on my issue on my android tv and black box(cable) or sky evo box.
    I connect my cable to my tv thru hdmi and it says that “video not supported”.
    I check all the connections and its properly connected.
    What am I suppose to do? Please? Ty

    1. What is the extension of the video file? If the video codec is unsupported, you might need to convert the video to mp4. You can try VLC on your computer. It’s free.

  7. Avdshare Video Converter supports to directly convert the unsupported MKV file to MX Player best supported video formats, like MKV H.264 AAC, MP4 H.264 AAC, etc.

  8. If your MP4 file includes audio codec that is not accepted by your device or player you can use a professional MP4 video converter – iDealshare VideoGo to convert your MP4 file to your device or player supported one with supported audio codec.

  9. a powerful iOS to Android Video Format Converter – iDealsahre VideoGo will help you easily solve your issues.

  10. Hi I was wondering if anyone could help me with an issue I’m having when I try to transfer photos and videos from an external usb storage device to my Samsung galaxy A70, when I connect the usb device to the phone it won’t even show up on the phone what’s on the storage device so Im not able to view and select anything that I want to transfer to the phone, I know that the storage device is ok because if I connect it to a much older Samsung galaxy phone I have it let’s me view what’s on it and I can transfer to that phone if I want to but it just won’t let me do the same on the newer Samsung galaxy A70. If anyone can help me with the problem or has any suggestions I would really appreciate it, many thanks.

    1. Hi, when I connect my phone with the computer, I have to go to the notifications and tap on the charging option and then choose “storage transfer”. I don’t know how it works with USBs, but you should check for any notifications when you plug it in.

  11. Hi, I have a Samsung Galaxy S8 phone. I’m having trouble playing some MP3s and MKV files. I’ve tried a few different players including VLC. The files that won’t play are the same ones I have previously been able to play before without a problem. I wonder if it’s an issue with the phone rather than the files or the players.
