Device slice:
  SDK: iphoneos
  CC: xcrun -sdk iphoneos -f clang
  CFLAGS/LDFLAGS: -arch arm64 -mios-version-min=17.0
  SYSROOT: xcrun -sdk iphoneos --show-sdk-path

Simulator slice:
  SDK: iphonesimulator
  CC: xcrun -sdk iphonesimulator -f clang
  CFLAGS/LDFLAGS: -arch arm64 -mios-simulator-version-min=17.0
  SYSROOT: xcrun -sdk iphonesimulator --show-sdk-path

Build and install:
  make
  make install with DESTDIR and prefix /

Packaging:
  The avutil, swscale, and avcodec dynamic libraries are copied into matching
  .framework bundles. Their install IDs are rewritten to
  @rpath/<name>.framework/<name>, and dependencies between those libraries are
  rewritten to the matching framework paths. Device and simulator frameworks
  are combined with xcodebuild -create-xcframework.

License-affecting flags intentionally absent:
  --enable-gpl
  --enable-nonfree
  --enable-version3
  --enable-libopencore-amrnb
