How to Fix AV1 You Need a Codec to Play This Item Error When Playing Videos
"Learn how to fix AV1 codec video playback issues on Windows with simple troubleshooting steps to play videos smoothly without errors."
Have you ever experienced an issue when trying to play a video on your laptop or computer, only to find that the video won't open or displays a black screen with no sound? even though the video file uses a common format like .mp4, which should be supported by most media players, what exactly causes this problem?
This issue often occurs because the built-in media player doesn't have the appropriate codec or doesn't support a particular type of video encoding, even if the video uses the .mp4 format, the video or audio codec used may not be included in the list of codecs supported by the media player.
In this article, we'll discuss the causes of video playback issues and how to fix them, especially if you're using Windows or another operating system with a built-in media player.
It's important to understand that video formats such as .mp4, .MKV, and .AVI are actually just containers, these containers hold other important components required to process and play videos, including video codecs such as H.264 or HEVC/H.265, as well as audio codecs such as .AAC, .mp3, or .AC3, therefore, even if your video file has the
.mp4 extension, it may still fail to play properly if the media player you're using doesn't have the appropriate codec to read its contents.This often happens with built-in media players such as Windows Media Player or the Movies & TV app in Windows 10, as both support only standard codecs, as a result, video files that use modern codecs or specialized encoding formats may fail to play or may not open at all.
If you're experiencing the issue described above, don't worry just yet, this is a fairly common problem that can usually be fixed with a few simple steps, in the following sections, we'll explain in detail how to fix videos that won't play due to codec issues or limitations of the built-in media player, so follow the tutorial carefully to get your videos playing smoothly again, now, let's get started with the tutorial below.
Tutorial:
- First, make sure you already have the file, if you don't have it yet, you can download it [Here] first.
- Once you have the file, scroll down until you find the green Download button.
- The Download button may still look somewhat transparent, so wait until it becomes a darker green, then click the button.
- Wait for the file you want to download to appear and become ready for download (however, if you're using your browser's built-in download manager, the file should download automatically).
- Once the file has finished downloading, run it by double-clicking it.
- A program window will appear, click the Install button.
