Hyunjun Ko of Igalia continues working on enhancing the Vulkan Video support in the Mesa ANV driver for better open-source video acceleration support. While Intel directly doesn't invest too much into Vulkan Video support in preferring their Video Acceleration (VA-API) media driver paired with the likes of oneVPL, Igalia has fortunately continued improving support for the cross-platform Vulkan Video API. The newest feature enabled for Mesa 27.0 is bitrate control for AV1 video encoding. Currently this support only works for Gfx12.5 generation hardware and when the HuC micro-controller firmware is loaded on the system. Gfx12.2 aligns with Intel DG2 / Alchemist and Meteor Lake graphics hardware. Hopefully AV1 video encoding with Vulkan Video at large comes to newer Xe2 and Xe3 hardware soon. Those interested in the bitrate control support for Vulkan Video AV1 encoding with the ANV driver can find all the details via this Mesa merge.
