• Intel ANV Driver Sees Several Vulkan Video H.265 Encode Fixes For those interested in Vulkan Video on the Intel “ANV” open-source Linux driver, merged last week to Mesa 26.1-devel were some H.265 encode fixes. • The Intel Vulkan Video support on Linux continues to improve largely thanks to the work of Igalia’s Hyunjun Ko. • Intel is largely focused on the VA-API / oneVPL story for video acceleration while the Igalia engineer has been working on enhancing Vulkan Video support for this open-source Intel Mesa driver. • In Mesa 26.1-devel and potentially to be back-ported for the Mesa 26.0 series are a number of fixes to the H.265 encode support. • Hyunjun Ko explained in the merge request: Beyond the work directly to the Intel ANV driver for Vulkan Video, Ko has also been working on fixes to the GStreamer multimedia framework as well with the most recent example to correctly play AV1 content on the Intel ANV driver. • The Intel Vulkan Video support on Linux continues to improve largely thanks to the work of Igalia’s Hyunjun Ko.

Article Summaries:

  • Intel’s open‑source “ANV” Vulkan Video driver for Linux has received a series of H.265 encode fixes in the Mesa 26.1‑devel branch, with a possible back‑port to Mesa 26.0. The updates, contributed by Igalia engineer Hyunjun Ko, address several encoder issues: dynamic transform‑skip settings based on QP, use of application‑provided QP values, proper handling of Generalized P and B frames, correct SAD QP Lambda values, and removal of unsupported features. Ko also worked on GStreamer fixes, notably enabling AV1 playback on the ANV driver. These changes continue to improve Intel’s Vulkan Video support on Linux.
