According to the official statement of the Open Media Alliance, Microsoft is currently testing the AVIF image format based on the AV1 codec in the Windows 10 Insider Preview.
The AVIF image format is derived from the AV1 video codec technology and is controlled by the Open Media Alliance, which is a primarily open source free without an authorization fee and so on.
Microsoft has been able to preview and load this image in the Windows 10 Version 1903 version of File Explorer and Paint Traditional.
Users who want to load images in AVIF format must also install the AV1 Video Expansion Kit, which allows Windows 10 to support AV1 video and images.
According to a post on AOMediaCodec’s Github,
- Windows File Explorer can show AVIF thumbnails, display Exif metadata and preview AVIF images. Requires the Windows 10 “19h1” preview release, which can be obtained from the Windows Insider program, and the AV1 Video Extension.
- MSPaint.exe. The “Paint” app in Windows 10 can display AVIF images. Requires Windows 10 “19h1” preview release build 18305 or later, which can be obtained from the Windows Insider program, and the AV1 Video Extension.
Support for the AVIF image format is available in Windows 10 19H1, but users may still need to install the AV1 video extension from the Microsoft Store to play AV1 video on their Windows 10 device.
