VA-API, the video acceleration API preferred by Intel and implemented by their open-source Linux graphics driver, now works with the stable Wayland 1.0 series. There was already VA-API Wayland support since last year to expose this hardware-accelerated video decode/encode process on the X.Org successor while now it's finally been updated to work with the stable 1.0 protocol.
The libva 1.1.1 release came on Monday per this announcement to bring the updated Wayland support and also some Automake fixes.
At the same time, libva-intel-driver 1.0.20 was released with the Intel hardware-specific video driver bits. Aside from Wayland protocol changes there, the Intel VA-API driver now supports global alphas for sub-picture, support for IA88/AI88 subpicture, up to four sub-pictures per surface, updated Haswell PCI IDs, and a couple of bug-fixes.
