WebM is an audiovisual media file format. The format is primarily intended to offer a royalty-free alternative to use in the HTML5 video and the HTML5 audio elements. So if you are familiar with HTML5 webpages, you must know that WebM is a good format for media contents. However, the HTML5-friendly video format always brings people problems when played offline, especially when you are using Windows Media Player. In fact, solving the Windows Media Player’s WebM playback issue is not hard, and there are multiple solutions to it. So now let’s see some of the best solutions to the Windows Media Player WebM playback issue.

Part 1: What's Great About WebM

Despite having some compatibility problems with media players like Windows Media Player, WebM is still a great video format. In fact, the main reason that the WebM format has been popular in the online video distribution channel for more than a decade is that it has some advantages that other video formats don’t have. For example, the following features are what has been keeping the WebM format important in the online video distribution industry.

  • Being completely free and open for anyone to use;
  • Being supported by mainstream video sites like YouTube;
  • Having great compatibility for even old computers, operating systems and platforms;
  • Having the ability to provide very high video quality;
  • Providing great video playback performance and stability.

Of course, there are more advantages that WebM has over other video formats. But the features in the above are good enough to keep the WebM format one of the best and most practical video formats in the online video distributing area. However, having various advantages doesn’t make WebM a perfect video format. Sometimes you can still encounter some playback problems with WebM videos, especially when you are using Windows Media Player. So in the following, there are 4 solutions provided for you to solve the WebM playback issue in Windows Media Player.

Part 2: Install WebM Codec to Play on Windows Media Player

The first solution for the WebM video playback issue in Windows Media Player, which is also the most direct solution, is to install a WebM codec on your Windows Media Player. A codec is a program that can make a certain video format or a certain set of formats play on your computer. Without the corresponding codec installed on your computer, there is no way that your computer can play the video file. And that’s the most common reason why the WebM videos could fail to play in Windows Media Player.

It is easy to solve the WebM video playback issue by installing the codec. Just follow the steps shown below and you should be able to play your WebM videos with the codec installed.

Step 1: Download the WebM codec. There are many codec packs that include the WebM support. Media Player Codec Pack, for one, is good enough for daily WebM playback tasks. Download the codec pack from its official website and launch the installer.

Step 2: Choose “Easy Installation” to make sure that you have everything necessary installed on your computer, and then click “Next” to proceed.

Step 3: You can change codec settings along the installing process, but it’s recommended that you keep every parameter as default so that nothing goes wrong when you play your WebM videos. Keep clicking “Next” until the codec is successfully installed on your computer.

Step 4: After the installation is finished, you can close the installer and try to play the WebM again with Windows Media Player. It should be played without a problem.

Part 3: Convert WebM to Windows Media Player Format

If you are dealing with the Windows Media Player’s WebM playback problem, installing a WebM codec like mentioned in the last part should be helpful. However, there is another solution if you don’t trust codec packs from the internet. After all, there are so many kinds of codec packs out there, and you never know whether the codec pack you find would do harm on your computer or not. So instead of downloading and installing a codec pack, you can download a video converter application to convert your WebM to a more compatible video format. By doing this, you can guarantee the safety of your computer and still fix the WebM video playback problem in Windows Media Player.

If you don’t already have a video converter installed on your computer, then I’d like to recommend Leawo Video Converter for your first choice.
