Third-party software notice: FFmpeg compiled to WebAssembly (ffmpeg.wasm) ========================================================================= Used by the free Audio Extractor at https://multistreamingplatform.com/tools/audio-extractor (see /assets/js/audio-extractor.js). It runs in the visitor's browser; files are not uploaded. Files in this folder -------------------- ffmpeg-core.js, ffmpeg-core.wasm Package @ffmpeg/core 0.12.10 (single-thread build), unmodified, from the npm registry. Contains FFmpeg n5.1.4 (libavcodec 59.37.100) and the libraries it was configured with. The package declares its license as GPL-2.0-or-later. This build was configured with --enable-gpl and includes GPL-licensed components such as x264 and x265, so it is distributed under the GNU General Public License, version 2 or (at your option) any later version. A copy of the GPL v2 is in COPYING.GPLv2.txt. Other libraries compiled into it (see the configure flags below) are covered by their own licenses, for example LAME (libmp3lame, LGPL) and FFmpeg's own libraries (LGPL-2.1-or-later, or GPL-2.0-or-later when GPL options are enabled). ffmpeg.js, 814.ffmpeg.js Package @ffmpeg/ffmpeg 0.12.15 (UMD build and its worker chunk), unmodified except that the trailing sourceMappingURL comment was removed.
