Microsoft Lands Initial AV1 Encoding Using DirectX 12 + HMFT Within Mesa 26.2

Microsoft has made a surprising move by integrating accelerated AV1 video encoding into the Mesa codebase using DirectX 12 and the Hardware Media Foundation Transform (HMFT). This marks a significant step forward in enhancing video encoding capabilities on GPUs, leveraging Windows-specific technology within the open-source ecosystem. It's a notable shift, as it combines proprietary and open-source technologies to push the boundaries of video encoding performance, which could lead to better video streaming and content delivery experiences. This collaboration between Microsoft and the open-source community underscores the growing importance of AV1, an open video codec that promises better compression and quality compared to older formats.
