Audio Codec Not Supported – Video Codec Unsupported Errors Fix 2022

Today, video content is the most popular type of multimedia content, and playing video files on a Windows PC or any other device can be fun. However, this as well as many troubleshooting concerns. While opening a video, you might be confronted with an error message such as 0xc00d36c4 or 0xc00d5212 (audio codec not supported) “unsupported audio codec”.

The issue would be grave, especially when you love this video file, even if it was saved in a well-known format like MP4 or MKV. Indeed, we will share the reasons and solutions which will help you if you are experiencing issues with video playback and cannot figure out why you get the not supported video and audio codec format error.


Three possible solutions to Audio or Video Codec not supported Errors


  • Install an not supported audio or video codec
  • Using a Third-Party Media Player
  • Change the video format to one supported by the player


What is the reason for not supporting video codecs?

Why does it say that video codecs are not supported? The media player doesn’t support the codec of your video. As a result, you only get the not supported video or audio codec error. In relation to the video file, what is a codec, and how does it work?


About the codec: 

The raw form of video and audio takes up a lot of space. Videos are compressed by proper compression standards and decompressed on the fly-by video players to save space or make them transferable. In this case, the word codec refers to the compression standard used to compress an audio or video stream. Video and audio codecs abound, including HEVC, H.264, AV1, DivX, MPEG2, MPEG4, AAC, AC3, etc.


About the container: 

The video and audio streams have to be combined for some reason. Hence, container format. If you have an HEVC video stream and an AAC audio stream, you can put them into a container like WMV, AVI, MP4, MOV, etc. Various container formats support different codecs. For instance, MKV and MP4 hold multiple videos, audio, and subtitle streams. MKV or MP4 files can be encoded in h.264, HEVC, AV1, WebM, VP9, and more.


On the other hand, every device comes with its own set of audio and video formats and codecs. Android phones, for example, only read AV1 files in MP4, MKV format when you upgrade to Android 10+. On an older Android phone, you will not be able to play videos with the AV1 codec. In contrast, you can play a MOV file on QuickTime, but when you import it to Windows 10, you may end up with nothing but an error message about video codecs not being supported.


This is why you receive an error message stating “video or audio codec not supported” or “unsupported video or audio codec” when you try to open media files on your Windows PC, Android device, or any other device.
