FFmpeg and the source code offer
Frame Repair includes two FFmpeg command-line programs as separate executables: ffmpeg version 7.1 and ffprobe version 7.0. Both are static arm64 builds configured with --enable-gpl (without --enable-version3), so they are licensed under the GNU General Public License version 2 or (at your option) any later version. Notable GPL components inside: x264, x265, vid.stab and FFmpeg's own postproc filters.
Configuration of both programs, as printed by -version:
--prefix=/Volumes/tempdisk/sw --extra-cflags=-fno-stack-check --arch=arm64 --cc=/usr/bin/clang --enable-gpl --enable-libvmaf --enable-libopenjpeg --enable-libopus --enable-libmp3lame --enable-libx264 --enable-libx265 --enable-libvpx --enable-libwebp --enable-libass --enable-libfreetype --enable-fontconfig --enable-libtheora --enable-libvorbis --enable-libsnappy --enable-libaom --enable-libvidstab --enable-libzimg --enable-libsvtav1 --enable-libharfbuzz --enable-libkvazaar --pkg-config-flags=--static --enable-ffplay --enable-postproc --enable-neon --enable-runtime-cpudetect --disable-indev=qtkit --disable-indev=x11grab_xcb

Sources of the libraries statically linked into these builds (x264, x265, vid.stab and the others listed in the configuration) and of the dependencies of the FFmpeg libraries inside OpenCV are provided on request. Upstream projects: x264 (videolan.org), x265 (multicoreware), vid.stab (github.com/georgmartius/vid.stab).
Written offer
For at least three years from the date you received your copy of Frame Repair, we will give anyone who contacts us at the address below, for a charge no more than the cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code of the GPL-licensed components contained in Frame Repair (GPL version 2, section 3(b)).
Source code requests: info@chfilm.de
The shipped FFmpeg executables are third-party static builds that we redistribute unmodified. The supplier did not record the exact versions of the linked libraries, so the offer covers the closest matching upstream sources.
