Compress Video to Size includes FFmpeg 9.0.2, licensed under the
GNU Lesser General Public License, version 2.1 or later.
FFmpeg is not modified; it is built without GPL or non-free parts and runs as a separate program
(ffmpeg and ffprobe next to the app), which you may replace with your own build.
- Source code of the exact version used: ffmpeg-9.0.2.tar.xz (SHA-256
8c3850283eb25fa026482078a04051e0be17347b09ef81a0849bec15a96e002e, the official release from ffmpeg.org) - Configuration: ffmpeg-config.sh; build scripts: macOS, Windows (Dockerfile, fetch)
- Video encoding uses the encoders of your operating system and graphics card (Apple VideoToolbox; NVIDIA NVENC, AMD AMF, Windows Media Foundation). On Windows the build uses the MIT-licensed NVENC and AMF headers.
To get the source on a physical medium instead, write to support@richardpham.com within three years of downloading the App.
