“I can’t play a video. Video codec not supported”

codec unsupported

Behind every media file is a codec program. The codec is responsible for compressing video data into various containers (.mp4, .3gp, .mp3, .mov, .avi etc…) and decompressing same files whenever someone needs to play them. Media players require the content of these containers (which could be any format) to be read properly; If not read properly, your media player will throw an error such as “Unsupported Codec”, “Audio Codec Not Supported” etc. Media players cannot support all codecs. If a media player doesn’t ‘understand’ a file, it will throw an error.

Continue reading to discover the various causes of these errors and the different ways to fix them.

Part 1. What Are the Causes of Audio Codec Not Supported or Codec Missing or Unavailable

Here are some of the well-known causes of unavailable or unsupported codec for audio files.

1. Unsupported File Type

The end result of a video file is data that has been compressed by certain codecs. When you attempt opening a video file with a media player, one of the first things done by the player is to check if it ‘understands’ the video data created by the particular codec; If it doesn’t, it throws an error.

2. Unavailable Codec

Media players have many codecs built into them, each time you open a file, it simply finds the appropriate codec file to use for decompressing your video file before playing it. If no appropriate codecs are installed/found, your media player throws an error.

3. Corrupt Video File

While some media players will try to ignore/fix minor errors on videos, some don’t –especially if the file is severely corrupt. File corruption can be caused directly by you or an infection on your device.
