Fix 2. Play Your Video with Another Media Player

Due to the absence of some specific codec, even the most used media player has some unsupported formats, like FLAC or FLA files. Not to mention other media players like Quicktime. So, you are advised to use another media player to open your video.

The better alternative is the VLC media player. This open-source software supports almost all major video formats and some feature formats with no codec packs needed and can even perform VLC repair. You can follow the instructions below:

Step 1. Download the VLC media player from its official website (available on Windows, macOS, iOS, and Android).

Step 2. When you finish installing the app, find and select the video file you want to play.

Step 3. Right-click on the video file and choose "Play with VLC media player" from the drop-down menu.

Or, you can launch the VLC media player first and go to "Media" > "Open File" and choose the video you want.

Fix 3. Convert the Format of the Video

Suppose you insist on using the media player you are currently running. In that case, you can try converting the video format the media player supports, like MP4 - the most-seen video format. You can also use this method to solve some common video playing problems like MP4 no sound. You can try utilizing the VLC media player to convert the format to resolve unsupported video codecs like this:

Step 1. Click its icon to open the VLC media player. Choose "Convert/Save" under "Media".

Step 2. Choose "Add" in the new window to upload the video you want to convert and click "Convert/Save".

Step 3. Now, you need to choose the new format from the drop-down menu in the "Profile" sections.

Fix 4. Download the Missing Audio and Video Codecs

If your video is intact and you still want to use your default player on Windows or Mac, you may attempt to download the missing audio and video codecs available online.

But they are not the best solution because a pack always comes with unknown viruses or malware.

Install codecs in Windows Media Player:

Step 1. Open Windows Media Player and find Organize > Options.

Step 2. When a new window opens, go to the Player tab and check "Once a day" or "Once a week" under the Automatic updates.

Step 3. Click "OK" and reopen your video to see if the Windows Media Player codec errors are gone.

choose automatic updates

Install codecs in the VLC media player:

Step 1. Click open the VLC media player and go to "Help" > "Check for Updates".

choose check for updates

Step 2. Click "Yes" when the new window shows up.

Step 3. Wait for the process to end, and try watching your video again.
