With AV1 Video Extension you can 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.
If you allow apps to be updated automatically, you should get the latest updates and improvements when we release them.
YouTube has integrated AV1 and determines which codec to use with a specific algorithm. Though, choosing to stream AV1 in HD is available only for a few videos due to its high resources requirement.
For SD, it will use AV1 up to 480p, and VP9 for higher formats.
AV1 Codec 1.0 - compiled by Chocobo1
includes x64 executables for Windows: aomdec.exe and aomenc.exe (AV1 decoder and respectively encoder).
AV1 is targeting an expected improvement of about 30% over VP9/HEVC with only reasonable increases in encoding and playback complexity.
