FFmpeg 8.1.1 for Enchant (macOS, Apple silicon) — build-id b0f30f7445ba

This is the complete corresponding source of the FFmpeg libraries shipped in
Enchant.app/Contents/Frameworks (libavcodec, libavformat, libavutil, libswscale, libswresample):
the unmodified upstream release ../../ffmpeg-8.1.1.tar.xz (sha256 b6863adde98898f42602017462871b5f6333e65aec803fdd7a6308639c52edf3),
configured with the line in ffmpeg_lgpl.conf and built by build_ffmpeg_lgpl.sh.
We made no changes to FFmpeg. BINARIES.sha256 lists the libraries it produced.

Licence: GNU Lesser General Public License version 2.1 or later (COPYING.LGPLv2.1).

Rebuild (macOS on Apple silicon, Xcode command line tools, Homebrew):
  brew install pkgconf dav1d libvpx opus
  ./build_ffmpeg_lgpl.sh ./ffmpeg-out --tarball ../../ffmpeg-8.1.1.tar.xz
  (build_ffmpeg_lgpl.sh reads ffmpeg_lgpl.conf from its own directory)

Use your own build (or a modified FFmpeg) with Enchant:
  1. copy ffmpeg-out/lib/libavcodec.62.dylib, libavformat.62.dylib, libavutil.60.dylib,
     libswscale.9.dylib and libswresample.6.dylib over the files of the same names in
     Enchant.app/Contents/Frameworks/
  2. re-sign the application locally so macOS will load it:
       codesign --force --deep --sign - /Applications/Enchant.app
