SRT Extractor — bundled ffmpeg integrity
=========================================

The ffmpeg / ffprobe shipped with this program are the UNMODIFIED official
Windows builds from gyan.dev. They are NOT rebuilt, patched, or repackaged —
only gzip-compressed for embedding. Verify with the SHA-256 hashes below.

Build:   ffmpeg 8.1.2-essentials_build-www.gyan.dev
License: GPL v3  (configured --enable-gpl --enable-version3, incl. libx264/libx265)

How to verify
-------------
Windows (PowerShell):   Get-FileHash <file> -Algorithm SHA256
Linux / macOS:          sha256sum <file>

1. Run the program once — it unpacks ffmpeg to %TEMP%\srtextractor-<hash>\ —
   OR gunzip the files in assets/.
2. Hash ffmpeg.exe / ffprobe.exe and compare with the values above.
3. For a fully independent check, download the same version from gyan.dev,
   extract it, and confirm the hash matches. It will, because these are the
   same original binaries — nothing here was modified.
