VA-API 1.0 Video Acceleration Is Approved For Fedora 28

[lu_tze]

To be precise and honest. For years I use libva (vaapi from 1.X branch) on AMD hardware and work well. Now I have installed in system libva2 and looks like it work also well. Just trying it with VLC3 and not see issue.

libva 1.x works fine under X11, but not Wayland. I had to use vdpau with mpv under Wayland. Make sure your VLC is really accelerated and doesn't fall back on non-accelerated code path.

This time you are wrong :-) In order to use VAAPI on modern architectures, especially with wayland and gles/gl interop via egl images is needed the ExportSurface API of version 2.1 is mandatory. So whenever you think of running kodi (upcoming v18) or mpv (git) without color degeneration you will need this upcoming version of vaapi.

Well, you could have some difficulty using vaapi 1.0 (libva 2.0) for years, given it was released last November.

The thing about libva 2.0 is, that it break API with previous versions. Not only it breaks API, the new API was designed with Intel hardware in mind, i.e. makes assumptions that may be not valid for other hardware. You can get the story here: https://github.com/intel/libva/pull/125

So for AMD devices, you need 2.1, otherwise you are going to have a bad time.

Trust me. I have been using vaapi for years on the amd card. Ofc it should be better and better with every new release but libva2.1 is not necessary for use on amd.

I think it was the API for multi-frame processing that was required for AMD cards

VAAPI work fine on AMD GPU even on libva from 1.x branch. So no needed to push too fast libva2.1.

libva 2.1 is required for the vaapi/opengl interop to work with amd gpus, although currently this also requires mesa-git so it won't work with fedora 28 out of the box anyways.

Shouldn't they be putting in 2.1 to enable stuff on AMD cards too

VAAPI work fine on AMD GPU even on libva from 1.x branch. So no needed to push too fast libva2.1.

This is changelog from libva2.1, so nothing important/related to AMD users.

 "*Bump VA-API version to 1.1.0 and libva to 2.1.0
Add API for multi-frame processing
Add entrypoint VAEntrypointStats for Statistics
Add data structures for HEVC FEI support
Add new attributes for decoding/encoding/video processing
Add new VPP filter for Total Color Correction
Add blending interface in VPP
Add rotation interface in VPP
Add mirroring interface in VPP
Add Chroma siting flags in VPP
Add new color standard definitions
Add new interface for exporting surface
Add message callbacks for drivers to use"

Libva2/vaapi 1 is available also in OpenMandriva LX3.03. This cool distro is build with Clang and not like many other distros with gcc.
