Phoronix: FFmpeg Now Works With VA-API On Windows Thanks To Microsoft

VA-API has been around for more than one decade as the most common Linux Video Acceleration API that works across multiple GPU/driver vendors. It's been Linux-focused to this point while thanks to the work of Microsoft has begun seeing support on Windows...

Good. Now, mpv and many others can drop Windows specific code and use only VA-API.

Are you sure isn't for WSL only and not native apps?

Are there any benefits to this or just to help run linux apps on WSL?

Native Windows applications timofonic.

In theory this opens up for Windows 7 or newer.

This is not realistic, vaon12 needs to implement d3d12 interoperability to use native vaapi hwdec, vaapi-copy on win32 performance is also disappointing. d3d11va nothing bad

For MPV and FFmpeg, Vaon12 makes little sense because MPV/FFmpeg will soon support Vulkan video, a cross-platform hwdec/hwaccel with absolute performance advantages and with a large number of directly usable vulkan hardware filters that do not require hwdownload.

vaon12 is based on d3d12 video, so it requires Windows 10/WDDM3.0

The last dev who proposed that was dropped from mpv project.

On a less bonkers note, this might actually be a good thing to avoid AMF and QuickSync in ffmpeg for occasional conversions.

IIRC there was some work on a vulkan backend for libva? I dont remeber much else about it, so while not immediate, the door is still open, though iirc ffmpeg is working on vulkan video support itself
