Neocodec 1.2.7/build51 — GPL corresponding source
========================================================================

Neocodec 1.2.7/build51 uses the FFmpeg and ffprobe 9.0.2 commercial pair
identified below. App-version-to-helper mappings are retained in the source README.

The prepared commercial helper set contains three independent open-source command-line
programs, intended as separate helper executables in Contents/Helpers/ (run as child
processes, never linked into the app):

  ffmpeg     9.0.2-neocodec-commercial        GPLv3 or later
             sha256 a6e35d85f8566edac5944b45552a4035772b4f0a9ca5b933998e9436182957cf
  ffprobe    9.0.2-neocodec-commercial        GPLv3 or later
             sha256 141e155fd6c8cd7f7078512cb604fbc70ef8980c49d7780294d285ba588cd30f
  gifsicle   1.96                           GPLv2 only
             sha256 9bb32495a20b9abb77e6be5f23db751aec59782b32d77cf13de5054b3caf46b7

ffmpeg and ffprobe are one static arm64 build from FFmpeg 9.0.2, x264 at commit
0480cb05fa188d37ae87e8f4fd8f1aea3711f7ee, SVT-AV1 3.1.2, libvpx 1.16.0, and
Opus 1.6.1. The build uses --enable-gpl --enable-version3 and is therefore
GPLv3-or-later. It deliberately does not build or link x265 and disables HEVC
encoding and decoding. gifsicle is GPLv2-only.

Those SHA-256 values identify the prepared binaries before bundle assembly. Bundle
assembly re-signs each helper with Neocodec's signing identity, which changes the bytes,
so a shipped helper will not have the same digest. Run `Contents/Helpers/ffmpeg -version`
to identify its version and configure line.

The source-only archive qualified on 6 October 2026 is:

    https://neocodec.com/source/neocodec-ffmpeg-9.0.2-commercial-source-f796441ef0ddcc252b5cfa5e50c7c45d2b7502a0752c5c5ca2a1423bf495eebc.tar.xz
    sha256 f796441ef0ddcc252b5cfa5e50c7c45d2b7502a0752c5c5ca2a1423bf495eebc
    bytes 40095792

It contains the current build disclosure and hardened packager. The build recipe,
configure flags and compiled source pins match the previously qualified helper pair;
this source-only qualification did not rebuild helpers. The older archive
neocodec-ffmpeg-9.0.2-commercial-source.tar.xz, sha256
a8613b5fab18d662aca82bcd39918fbbd77a21d07db40a6f48fb212779446a72,
remains retained with its original bytes.

The source is hosted for as long as any corresponding binary remains distributed. The
full GPLv3, GPLv2, LGPLv2.1, SVT-AV1 BSD-3-Clause-Clear and legacy BSD-2-Clause,
Alliance for Open Media Patent License, libvpx
license and additional patent grant, and Opus license texts also ship inside the app
under Settings > About > Licenses.

The proprietary Neocodec application is a separate work that invokes these programs as
child processes; this notice identifies those bundled helpers and their corresponding source.
