Written offer for complete corresponding source (LGPL 2.1 section 6)
====================================================================

This distribution of ContentNotes bundles executable build(s) of the
FFmpeg library suite (bin/ffmpeg on macOS; bin/ffmpeg.exe for Windows,
when present), licensed under the GNU Lesser General Public License
version 2.1 or later. The licence text ships in this distribution as
licenses/ffmpeg-LGPL.txt.

The complete corresponding source code for each bundled binary is the
same UNMODIFIED FFmpeg 7.1.1 source release:

  Upstream tarball : https://ffmpeg.org/releases/ffmpeg-7.1.1.tar.xz
  SHA-256          : 733984395e0dbbe5c046abda2dc49a5544e7e0e1e2366bba849222ae9e3a03b1

No source modifications were made. The binary was produced from that
tarball on macOS (Apple silicon) with Apple clang, using exactly this
configure line — note the absence of --enable-gpl and --enable-nonfree;
the build is LGPL-2.1-or-later throughout:

  ./configure --cc=clang --arch=arm64 --disable-everything
    --disable-autodetect --disable-network --disable-doc --disable-debug
    --disable-avdevice --disable-postproc --disable-ffplay
    --disable-ffprobe --enable-protocol=file,pipe
    --enable-demuxer=mov,mp3,wav,aac,flac,aiff
    --enable-decoder=aac,alac,flac,mp3,opus,pcm_s16le,pcm_s16be,pcm_s24le,pcm_s24be,pcm_s32le,pcm_s32be,pcm_f32le,pcm_f64le,pcm_u8
    --enable-parser=aac,mpegaudio,flac
    --enable-encoder=pcm_s16le --enable-muxer=null
    --enable-filter=astats,aresample,aformat,anull,ametadata,asetnsamples

followed by "make". The Windows binary (bin/ffmpeg.exe) was produced
from the SAME tarball, cross-compiled on macOS with the mingw-w64
toolchain (GCC 16.1.0, Homebrew mingw-w64 14.0.0_2), using the same
component set — only the platform flags differ:

  ./configure --enable-cross-compile --cross-prefix=x86_64-w64-mingw32-
    --arch=x86_64 --target-os=mingw32 --extra-ldflags=-static
    --disable-everything --disable-autodetect --disable-network
    --disable-doc --disable-debug --disable-avdevice --disable-postproc
    --disable-ffplay --disable-ffprobe --enable-protocol=file,pipe
    --enable-demuxer=mov,mp3,wav,aac,flac,aiff
    --enable-decoder=aac,alac,flac,mp3,opus,pcm_s16le,pcm_s16be,pcm_s24le,pcm_s24be,pcm_s32le,pcm_s32be,pcm_f32le,pcm_f64le,pcm_u8
    --enable-parser=aac,mpegaudio,flac
    --enable-encoder=pcm_s16le --enable-muxer=null
    --enable-filter=astats,aresample,aformat,anull,ametadata,asetnsamples

followed by "make". The exact binary identities (byte size and MD5) are
recorded in bin/MANIFEST.md and verified at release time.

OFFER: for a period of at least three (3) years from your receipt of
this distribution, we will provide the complete corresponding source
code described above (the upstream tarball plus these build
instructions) to any third party, at no charge beyond the cost of
distribution, on request via the ContentNotes support contact shown on
the product page where you obtained this software.
