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 in the audio, then you get an audio error and same with video. If that’s what you are facing, then here are three ways to fix this issue.
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.

What is a codec?
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 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 you play the video which contains that codec, it 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.
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, there is MX Player, which also supports the majority of formats.

Using a video converter on Android
You may want to play the video in the default video player. The easiest way is to covert the video on Android. Try Video Converter to convert the video. MP4 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.
Using a video converter on PC
These days it’s hard to find a free and relevant video converter. Once the video is transferred to the PC, download a video converter. A couple of converters are Freemake Video Converter and Any Video Converter. The free versions have limited features and may leave a watermark, but you can Google by yourself and see if a better is available. While converting, make sure you understand what resolution your device supports. If your device is one of the latest ones, then 1080p would be fine. Otherwise, 720p is the ideal choice.
Looking for an all-in professional video converter? Try UniConverter on your PC to convert files in high quality.
If you still need some help, here is a step by step tutorial. The post uses Freemake Video Converter, but the technique should be similar 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.
Step 03: The convert screen will come up. It would take some time to convert the video. Click on the “Convert” button to begin. Once the video is converted, you will be able to play the video on your Android device.
