License

FFmpegKitNext itself is licensed under the LGPL v3.0.

FFmpegKitNext bundles (.aar archives, frameworks, and xcframeworks), which include both FFmpegKitNext and FFmpeg libraries, are also licensed under the LGPL v3.0. However, if the source code is built with the optional --enable-gpl flag, the resulting FFmpegKitNext bundles become subject to the GPL v3.0, because the included FFmpeg libraries are then licensed under the GPL v3.0.

FFmpegKitNext build scripts always configure FFmpeg with the --enable-version3 option and never enable non-free libraries. Therefore, FFmpeg libraries built by FFmpegKitNext are licensed under the LGPL v3.0 by default. They become subject to the GPL v3.0 only when the --enable-gpl option is enabled.
