For those interested in making use of GPU-accelerated AV1 video decoding with Intel graphics hardware using the Vulkan Video API, some important fixes were merged to Mesa 25.2-devel and will presumably be backported soon to existing Mesa releases.

The open-source Intel "ANV" Vulkan driver has seen some notable fixes merged for its AV1 video handling with Vulkan Video.

The three patches now in Mesa Git address some artifacts that could appear during the AV1 decoding process as well as taking care of a possible Intel GPU hang during the AV1 decode handling.

The fixes involved allocating enough MV buffers, fixing the CDEF filter flag, and ensuring CDF tables are allocated. The fixes were sorted out by Igalia engineer Hyunjun Ko.
