FFmpeg (LGPL-2.1-or-later), unmodified: the exact source is the release tarball (also attached to this
release)

configured as port/tools/deps.py's build_ffmpeg_shared records in the corresponding source (decoders bink,
binkaudio_dct, binkaudio_rdft, the bink demuxer and the file protocol only),

The program loads FFmpeg's shared libraries from this folder, so
they can be replaced with a modified build of the same version. FFmpeg gives no patent assurances; the Bink
formats are RAD Game Tools'. The program decodes only the player's own game files.
The Xiph.Org Foundation's name is not used to endorse or promote this program.

The public graphics host (port/platform/public/d3dapp.cpp and d3dapp.h) is GPL-3.0-only code by
the Onslaught CE contributors. The inherited SDK sample framework is not included in this package.

Source paths from llvm-mingw's own build machine (folders named llvm-mingw, llvm-project and mingw-w64) remain
in three files: bea.exe, inside its statically linked libc++abi and libunwind, and SDL3.dll and libz.dll,
inside the MinGW-w64 runtime objects linked into them. They are llvm-mingw's folders, not this program's.
