HS Show 0.1.0 - corresponding media-library sources

Extract base-media-source.tar.gz. It contains the complete patched FFmpeg source and zlib/dav1d sources, their licenses and base MSVC build recipes. Follow BASE-SOURCE-README.txt to build the two static dependencies. Then run scripts/build-hs-show-ffmpeg.sh in the same MSVC x64 / MSYS2 environment. Set HS_SHOW_MEDIA_SOURCE to that base directory and HS_SHOW_MEDIA_OUTPUT to a new empty directory; set INCLUDE/LIB to the dependency install paths. The PowerShell wrapper documents environment setup, but its machine-specific paths and HS audit prerequisite are not needed to rebuild the shell recipe.

This is a different configuration from HS Material: it retains DirectShow audio input and PCM float output for real LTC. GPL, nonfree, version3, autodetection, network protocols and audio/video output devices are disabled. Chromaprint and FFTW are excluded. The shared FFmpeg DLLs are used under LGPL-2.1-or-later. The exact configure result is config.mak and binary hashes are in media-pins.json.

No HS authorization secrets, vendor QCAP DLLs, model weights or user media are included. Users may modify/replace compatible LGPL libraries and reverse-engineer the combined work to debug these changes. Recalculate the locally distributed integrity inventory and component pin declarations for a modified installation; it is no longer the official verified package. HS account authorization is independent.
