Windows Media Player has been the primary media player on the Windows platform. It has all the basics that a standard media playing software has, and it can play videos in common formats that can be opened effortlessly. However, error messages can sometimes randomly pop-up, even when you are trying to open video formats supported by Windows Media Player. In this guide, we will focus on the 0xc00d5212 error which pops-up on Windows Media Player, and show you how to fix it.

Part 1: What is error 0xc00d5212 in WMP

If you are a Windows Media Player user, the error 0xc00d5212 is an error message that pops up when you try to play AVI videos in the media player. When this error code pops up, there is really nothing you can do except to close the player, since it essentially prevents the playback. Interestingly, the AVI video format has been in development since 1992 from Microsoft itself. Having this error pop-up is therefore odd, and some users have reported that they can successfully open other AVI videos on Windows Media Player without issues. Therefore, why does this happen? Quite simply, this is because of a missing codec 0xc00d5212, and sometimes outdated video drivers. We will investigate further why this error pops-up on the next segment of this article.


Part 2: Why this error pops up while playing video

Technology is constantly evolving, and in terms of videos, codecs are responsible for bringing the advancements. Therefore, getting the error 0xc00d5212 when you are playing some AVI files is usually because of missing video codecs. Outdated video drivers can cause this error, and according to Microsoft support who have investigated this issue, this problem can also pop-up if you have installed audio drivers that may not work properly with the video drivers. Even when you run the Windows Media Player troubleshooter, this error code may continue to pop-up. Although this error message pops up with a concise description, with an error code that is cryptic for anyone to understand, the reasons above are responsible for this error.

Part 3: Effective ways to fix this error

Because many factors cause this error to pop-up, there is more than one way to effectively fix this problem. Therefore, we will provide you with multiple ways to fix this problem.

1. Uninstall your recent audio drivers

As we stated in the preceding part of this article, this problem can be caused by the installed audio drivers that may not work properly with the video drivers. To fix it, uninstall them in Windows Device Manager by following the steps below:


Step 1: Right-click the Windows key and click Device Manager.
Step 2: In the Device Manager, expand the Sound, video and games controllers, right click on any 3rd party audio device, and click Uninstall.
Step 3: In the Confirm Device Uninstall window, make sure to check the Delete the driver software for this device option, then click OK.
Step 4: Restart your computer, and try to play the AVI video again.

2. Update your video drivers

If you are running Windows 10, Microsoft has made it a lot easier to install updates for the software and hardware updates, as it now makes it possible to download everything through Windows Update. Therefore, you simply need to run Windows Update, then check if you have any incoming updates that you should install on your computer. Alternatively, you can open your video driver application, to check for the updates within the application itself. If any updates are available, the application will provide you with the details and the step by step guide on how to do so.


3. Install the missing codecs

If you are sure that you have the latest video drivers installed on your computer, and if you are sure that your audio drivers are not influencing your video drivers to cause the 0xc00d5212 error, then you simply need to install the required codecs. The best way to install any missing codecs on your computer is to install a codec pack, which should ensure that you never run into other codec issues again. The codec pack we would recommend you to install is the k-lite codec pack. It has 4 different packages which are Basic, Standard, Full and Mega packs. If you are looking for all the available options, then go for the mega pack.

The Basic pack contains everything you need to play all common audio and video file formats. The Standard pack contains everything from the basic pack plus Media Player Classic- Home Cinema, MadVR and MediaInfo Lite. The Full pack has everything from the standard pack, plus the DC-Bass Source Mod, GraphStudioNext and a plugin for 3D video decoding (H.264 MVC). Lastly, the Megapack has everything from Basic, Standard and Full packs, with a few ACM/VFW codecs such as x264VFW. After you download and install the K-lite codec pack, you can open pretty much any video without issues. Therefore, download the K-lite codec pack from this link, and follow the installation instructions down below:

Step 1: Download and run the installation file on your computer.
Step 2: On the installer, leave all options default and continue to click Next.
Step 3: Depending with the K-lite codec pack you downloaded, decide whether or not you need to install Media Player Classic- Home Cinema when prompted.
Step 4: Configure the speakers. Select the desired channel output for the audio decoders from the codec pack. When you are done, click Next then finally click Install to begin installation.
Step 5: When the codec pack has finished installing, it is recommended to restart your computer. When your computer restarts, try opening the AVI video on Windows Media Player again.
