Play AV1 videos on your Windows 10 device. This extension is an early beta version of the AV1 software decoder that lets you play videos that have been encoded using the AV1 video coding standard developed by the Alliance for Open Media. Since this is an early release, you might see some performance issues when playing AV1 videos. We’re continuing to improve this extension. If you allow apps to be updated automatically, you should get the latest updates and improvements when we release them.
