WDX for Windows - Third-Party Software Notices ============================================== WDX for Windows ("WDX") is distributed by WDX Labs. WDX includes or is derived from the third-party components listed below. Each component is licensed by its own authors under the license stated here; those licenses, not the WDX end-user license, govern your use of that component. Nothing in the WDX end-user license restricts the rights these licenses give you. Full license texts that are too long to reproduce inline are shipped next to this file: LGPL-3.0.txt GNU Lesser General Public License, version 3 GPL-3.0.txt GNU General Public License, version 3 (LGPL-3.0 incorporates its terms by reference) Licenses of the Flutter engine and Dart packages used by the WDX user interface are listed inside the application (About > Licenses) and in data/flutter_assets/NOTICES.Z. Contents 1. FFmpeg (LGPL-3.0-or-later) 2. Virtual Display Driver (MIT) 3. Windows Driver Frameworks (MIT) 4. Virtual Audio Driver (MIT) and Microsoft Windows Driver Samples (MS-PL) 5.

FFmpeg ------------------------------------------------------------------------------ Files: avcodec-62.dll, avformat-62.dll, avutil-60.dll, swresample-6.dll, swscale-9.dll Version: FFmpeg n8.1.3-14-g330caae0c1 (release/8.1 branch) Source: https://git.ffmpeg.org/ffmpeg.git commit 330caae0c1acccd2222edc52a05940c574561ce5 (mirror: https://github.com/FFmpeg/FFmpeg/tree/330caae0c1acccd2222edc52a05940c574561ce5) Build: BtbN FFmpeg-Builds, variant win64-lgpl-shared-8.1, release tag autobuild-2026-10-03-18-14 (build scripts: https://github.com/BtbN/FFmpeg-Builds/tree/9acad4a9ef1583096af7836cc1e9c8cbcb4d3950) License: GNU Lesser General Public License, version 3 or (at your option) any later version - see LGPL-3.0.txt and GPL-3.0.txt. FFmpeg is a trademark of Fabrice Bellard, originator of the FFmpeg project. Copyright (c) the FFmpeg developers. See https://ffmpeg.org/legal.html. FFmpeg was built WITHOUT --enable-gpl and WITHOUT --enable-nonfree. It is used, unmodified, as separate dynamic link libraries (DLLs). You may replace these DLLs with your own build of FFmpeg that keeps the same ABI (libavcodec 62, libavformat 62, libavutil 60, libswresample 6, libswscale 9); WDX loads whichever DLLs are present in its installation folder. Reverse engineering of WDX to the extent needed to debug such modifications is permitted. The complete corresponding source code of FFmpeg and of the libraries statically linked into these DLLs can be obtained from the locations above. WDX Labs will also provide a copy of that source code, for no more than the cost of physically performing the distribution, for at least three years after the last distribution of this version of WDX; contact the email address listed on https://wdxapp.com. The BtbN build statically links the following libraries into the FFmpeg libraries it produces (a few only into libraries WDX does not ship), each under its own license (full license texts are included with each upstream source package referenced by the build scripts above): zlib (Zlib), liblzma/xz (0BSD), libiconv (LGPL-2.1-or-later), libxml2 (MIT), dav1d (BSD-2-Clause), libaom (BSD-2-Clause + AOM patent license), libvpx (BSD-3-Clause), Opus (BSD-3-Clause), libogg/libvorbis (BSD-3-Clause), LAME (LGPL-2.0-or-later), libtheora (BSD-3-Clause), libwebp (BSD-3-Clause), libjxl (BSD-3-Clause), OpenJPEG (BSD-2-Clause), OpenH264 (BSD-2-Clause), Kvazaar (BSD-3-Clause), SVT-AV1 (BSD-3-Clause-Clear + AOM patent license), rav1e (BSD-2-Clause), VVenC (BSD-3-Clause-Clear), OpenAPV (BSD-3-Clause), uavs3d (BSD-style), TwoLAME (LGPL-2.1-or-later), opencore-amr (Apache-2.0), ZVBI (LGPL-2.0-or-later), aribb24 (LGPL-3.0-or-later), libaribcaption (MIT), Snappy (BSD-3-Clause), LCEVCdec (BSD-3-Clause-Clear), librsvg (LGPL-2.1-or-later) and its dependencies, libgme (LGPL-2.1-or-later), libopenmpt (BSD-3-Clause), libbluray (LGPL-2.1-or-later), libssh (LGPL-2.1), SRT (MPL-2.0), librist (BSD-2-Clause), ZeroMQ (MPL-2.0), Chromaprint (LGPL-2.1-or-later), GMP (LGPL-3.0-or-later), soxr (LGPL-2.1-or-later), FreeType (FTL), HarfBuzz (MIT), FriBidi (LGPL-2.1-or-later), Fontconfig (MIT-style), Little CMS (MIT), Intel oneVPL dispatcher libvpl (MIT), NVIDIA nv-codec-headers (MIT), AMD AMF headers (MIT), Khronos OpenCL ICD loader (Apache-2.0), Vulkan headers (Apache-2.0), mingw-w64 runtime and winpthreads (ZPL-2.1 / MIT / BSD), GCC runtime libraries (GPL-3.0 with GCC Runtime Library Exception). ------------------------------------------------------------------------------ 2.
