    Dav1d 1.4.1 “Road Runner”

    dav1d 1.4.1 is a small release of dav1d, improving notably ARM and RISC-V speed

    • Optimizations for 6tap filters for NEON (ARM), that can be significative depending on the samples
    • More RISC-V optimizations for itx (4×8, 8×4, 4×16, 16×4, 8×16, 16×8)
    • Reduction of binary size on ARM64, ARM32 and RISC-V
    • Fix out-of-bounds read in 8bpc SSE2/SSSE3 wiener_filter
    • Msac optimizations

    SVT-AV1 2.0.0 (2024-03-13)

    Major API updates

    • Changed the API signaling the End Of Stream (EOS) with the last frame vs with an empty frame
    • OPT_LD_LATENCY2 making the change above is kept in the code to help devs with integration
    • The support of this API change has been merged to ffmpeg with a 2.0 version check
    • Removed the 3-pass VBR mode which changed the calling mechanism of multi-pass VBR
    • Moved to a new versioning scheme where the project major version will be updated every time API/ABI is changed
    Encoder
    • Improve the tradeoffs for the random access mode across presets:
    • Speedup presets MR by ~100% and improved quality along with tradeoff improvements across the higher quality presets (!2179,#2158)
    • Improved the compression efficiency of presets M9-M13 by 1–4% (!2179)
    • Simplified VBR multi-pass to use 2 passes to allow integration with ffmpeg
    • Continued adding ARM optimizations for functions with c_only equivalent
    • Replaced the 3-pass VBR with a 2-pass VBR to ease the multi-pass integration with ffmpeg
    • Memory savings of 20–35% for LP 8 mode in preset M6 and below and 1–5% in other modes / presets
    Cleanup and bug fixes and documentation
    • Various cleanups and functional bug fixes
    • Update the documentation to reflect the rate control changes

    libOpus 1.5 & 1.5.1 (2024-03-04)

    Opus 1.5 Released

    Opus 1.5 is the first release to make extended use of ML in the encoder and decoder. You can read all the details in this release demo page. In summary, major changes since 1.4 include:

    • Significant improvement to packet loss robustness using Deep Redundancy (DRED)
    • Improved packet loss concealment through Deep PLC
    • Low-bitrate speech quality enhancement down to 6 kb/s wideband
    • Improved x86 (AVX2) and Arm (Neon) optimizations
    • Support for 4th and 5th order ambisonics

    In addition to the improvements above, this release includes many minor bug fixes. Opus 1.5.1 fixes the meson build that was broken in 1.5.
