FULL LICENSE TEXTS MIT, BSD-2-Clause, Apache-2.0, GNU GPL v2, GNU LGPL v2.1 =============================================================================== A. BUNDLED MEDIA STACK (GPL / LGPL) Reelm bundles the mpv media stack INSIDE the application package (MSIX) and invokes mpv as a SEPARATE PROCESS (command line + JSON IPC). The mpv binaries are NOT linked into the Reelm application code: they are merely aggregated in the same package and run as an independent program. Under the GNU GPL FAQ this is "mere aggregation", and it does NOT place the Reelm application itself under the GPL. These components are BUNDLED in the package - they are NOT downloaded at first launch. (Any earlier statement that "mpv is downloaded on first run" is obsolete and does not apply to this Store build.) CORRESPONDING SOURCE (GPL/LGPL). The complete, exact corresponding source of the bundled mpv build - mpv, the statically included FFmpeg, the build recipe, and uosc, each with its SHA-256 checksum, plus a build manifest and README - is published at: https://mediaboxmc.com/oss/mpv/20260610-304426c/ WRITTEN OFFER (GNU GPL v2, Section 3b). For any GPL/LGPL component of this build not directly mirrored above, the complete corresponding source is available on request, at no charge beyond the cost of distribution, for at least three (3) years from the date of distribution. Contact: [email protected] PATENTS (independent of copyright license). Certain codecs (e.g. H.264, HEVC) may be covered by third-party patents; the open source licenses grant no patent rights. The app prefers operating-system / hardware decoders and royalty-free codecs (AV1, VP9) where available. =============================================================================== 1. MPV https://mpv.io https://github.com/mpv-player/mpv mpv is the media player used by Reelm. It is bundled in the application package and launched as a separate process that communicates with Reelm over a JSON IPC channel. mpv is NOT statically or dynamically linked into the Reelm binary. Bundled build: mpv-x86_64-20260610-git-304426c (mpv git 304426c, shinchiro build recipe tag 20260610). Files shipped include mpv.exe, mpv.com, d3dcompiler_43.dll and the mpv configuration. Copyright (C) the mpv project contributors. License: GNU General Public License, version 2 or later (GPL-2.0-or-later). The full GPL v2 text is reproduced in Section E. Corresponding source: https://mediaboxmc.com/oss/mpv/20260610-304426c/ =============================================================================== 2. FFMPEG https://ffmpeg.org FFmpeg provides the audio/video decoding and demuxing libraries used by mpv. It is compiled STATICALLY INSIDE the bundled mpv build; no standalone ffmpeg, ffprobe or ffplay executable is shipped. Copyright (C) the FFmpeg developers. The FFmpeg core libraries are licensed under the GNU Lesser General Public License, version 2.1 or later (LGPL-2.1-or-later). The mpv build bundled here is compiled with GPL-licensed components enabled, so the shipped FFmpeg build is effectively GNU GPL v2 or later (GPL-2.0-or-later). It is NOT built with --enable-nonfree. The full GPL v2 and LGPL v2.1 texts are reproduced in Section E. Corresponding source: https://mediaboxmc.com/oss/mpv/20260610-304426c/ =============================================================================== 3. UOSC - MODERN OSC FOR MPV https://github.com/tomasklaen/uosc Copyright (C) tomasklaen and contributors. License: GNU Lesser General Public License, version 2.1 (LGPL-2.1). uosc is the on-screen user interface for mpv, written as an mpv Lua script. It is bundled unmodified, extracted to the writable per-user mpv configuration directory on first launch, and runs as a script inside the separate mpv process. It is NOT part of the Reelm binary. The full LGPL v2.1 text is reproduced in Section E. Corresponding source: https://mediaboxmc.com/oss/mpv/20260610-304426c/ =============================================================================== B. NATIVE LIBRARIES (vcpkg - statically linked) The following native libraries are compiled from source via vcpkg and statically linked into the Reelm application binaries shipped inside the package. =============================================================================== 4. SQLITE (incl. FTS5) https://www.sqlite.org Version 3.53.1, built with the FTS5 full-text search extension. SQLite is in the Public Domain. The authors disclaim copyright to the source code.
