FFmpeg and FFprobe
The application bundles FFmpeg and FFprobe (ffmpeg.exe and ffprobe.exe) as separate executables, licensed under the GNU General Public License, version 3 or later (GPL-3.0-or-later). Copyright (c) 2000 to present, the FFmpeg developers. The Windows binaries are the gyan.dev "full_build" of FFmpeg 8.0.1 (FFmpeg commit 894da5ca7d). Because that build also compiles in additional libraries, the corresponding source covers those as well, not FFmpeg alone:
- FFmpeg 8.0.1 source: github.com/GyanD/codexffmpeg (8.0.1), upstream ffmpeg-8.0.1.tar.xz
- x264, software H.264 encoder (GPL): code.videolan.org/videolan/x264
- x265, software H.265/HEVC encoder (GPL): bitbucket.org/multicoreware/x265_git
