  March 16th, 2026, FFmpeg 8.1 "Hoare"

   A new minor release, FFmpeg 8.1 "Hoare", is now available for download. Here are some of the
   highlights:
     * Decoders: xHE-AAC Mps212 (experimental) MPEG-H decoding via libmpeghdec
     * EXIF Metadata Parsing
     * LCEVC: support for parsing and forwarding metadata
     * Vulkan compute-based codecs: ProRes encoding and decoding, DPX decoding
     * D3D12: D3D12 H.264/AV1 encoding, scale_d3d12, mestimate_d3d12, deinterlace_d3d12 filters
     * Rockchip H.264/HEVC hardware encoding
     * IAMF: Projection mode Ambisonic Audio Elements muxing and demuxing
     * Formats: hxvs demuxer
     * Filters: drawvg, vpp_amf

   This release features a lot of internal changes and bugfixes. The groundwork for the upcoming
   swscale rewrite is progressing. The Vulkan compute-based codecs, and a few filters, no longer
   depend on runtime GLSL compilation, which speeds up their initialization.

   A companion post about the Vulkan Compute-based codec implementations has been published on
   the Khronos blog, featuring technical details on the implementations and future plans.

   We recommend users, distributors, and system integrators to upgrade unless they use current
   git master.

Hopefully just renaming our  ffmpeg 8.0 patches to 8.1 will make it work (but with new libdav1d). I tested ffmpeg.git few days ago (see email archive) and it was working for simple decoding, vaapi/vulkan decoding and vaapi encoding. But there still might be surprises in less used parts like BD creation.
