## ffmpeg (GPL v3) and its source

ffmpeg is a SEPARATE PROGRAM: MAPu does not link against it, but launches it as an independent process and talks to it over its standard input/output. The bundled copy is an unmodified, official BtbN/FFmpeg-Builds build: ffmpeg-n8.1.2-54-gc573a95381-win64-gpl-8.1, SHA256 2d54d4e040e944520e9cc2c23083d7d7e6376d15a8eead22bff260d6ad4505c8. It is a STATIC binary: libx264, libx265, SVT-AV1 and some 90 further libraries are compiled into it, so under section 6 of the GPL v3 it comes with its COMPLETE source — the FFmpeg source (github.com/FFmpeg/FFmpeg, commit c573a95381b0), the build recipe (github.com/BtbN/FFmpeg-Builds, commit 3e6685eda92f) and the source of every linked library at the revision the recipe pins. The list is the SOURCES.md shipped next to the binary (in the installation's resources/vendor/ffmpeg folder): every item points at its original upstream repository, at the exact commit — the link above is the commit of the FFmpeg source. MAPu keeps a retained copy of every item; should an upstream address disappear, that archive is published at https://kotysoft.com/mapu/ffmpeg-src/. (BtbN's own release page deletes old builds, so the binary's original download address is not permanent — the README.md describes it.) The copy is REPLACEABLE: the ffmpeg.exe and ffprobe.exe in the installation's resources/vendor/ffmpeg folder can be swapped for another build with the same capabilities — running the igazolas.ps1 next to it tells you whether the new copy can do everything MAPu calls for. The README.md in the same folder describes exactly which build this is, where it came from and what it was compiled with.
