How to Add AV1 Codec Support to Windows 10

AOMedia Video 1 (AV1) is an open, royalty-free video coding format designed for video transmissions over the Internet. It is being developed by the Alliance for Open Media (AOMedia), a consortium of firms from the semiconductor industry, video on demand providers, and web browser developers, founded in 2015. The AV1 bitstream specification includes a reference video codec.

Microsoft has released the AV1 Video Extension app that will allow you to play AV1 videos in your favorite video app on your Windows 10 build 17763 or higher PC. This extension helps video apps installed on Windows 10 play videos that have been encoded using the AV1 video coding standard developed by the Alliance for Open Media.

When you install the AV1 video codec, any app such as Microsoft Edge, Movies & TV, and Windows Media Player can use the codec to play AV1 videos.

This tutorial will show you how to add AV1 codec support to play AV1-encoded video content in Windows 10 for your account.

Here's How:

1 Download and install the free AV1 Video Extension app from the Microsoft Store.

If you should want to uninstall the AV1 Video Extension app, you can do so on the App & features page in Settings.

To verify and see if a video supports and is using the AV1 codec, right click or press and hold on the video, and click/tap on Stats for Nerds. If you see av01 for Codecs, then the video is using the AV1 codec. (see screenshots below)
