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. If the issue is with the audio, then you get an audio error and with video, it’s a video error. If that’s what you are facing, then here are three different fixes in 2020.

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 follow the way 2 or way 3. 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 and you play the video which contains that codec, the player will not 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 formats 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 sound. In that case, the audio may not be supported.
Converting on PC
There are plenty of video converters out there, but most of them leave a watermark or limit on the video quality. In this blog post, we are going to use the free, fast, and an open-source software which you probably already have installed. Just like on Android and iOS, VLC PC 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.
Open VLC Media Player once downloaded and installed.
Go to Media on the top right, and then click on Save/Convert.
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.
The next step is important. We need to select the profile for the video. New Android devices support full HD resolution videos these days, 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.
With great phones and apps, we expect everything to be fine, but it’s not the case. I hope you found the solution to your issue. Please feel free to ask any questions in the comments and subscribe to the newsletter for post updates.
