# Build static FFmpeg libraries for Android using prebuilt libvpx, dav1d and Opus.
# Configuration is kept equivalent to build_ffmpeg_libvpx_dav1d_android_ndk27_merged.sh.
#
# Inputs:
# jni/prebuild/lib/<ABI>/libvpx.a
# jni/prebuild/lib/<ABI>/libdav1d.a
# jni/prebuild/lib/<ABI>/libopus.a
# jni/prebuild/pkgconfig/<ABI>/{vpx,dav1d}.pc
# source headers from jni/third_party/{libvpx,dav1d,xiph/opus,ffmpeg}
# generated/ABI headers overlay from jni/prebuild/include/<ABI>
#
# Output:
# jni/prebuild/lib/<ABI>/libavcodec.a
# jni/prebuild/lib/<ABI>/libavformat.a
# jni/prebuild/lib/<ABI>/libavutil.a
# jni/prebuild/lib/<ABI>/libswscale.a
# jni/prebuild/lib/<ABI>/libswresample.a
# generated/ABI-dependent FFmpeg public headers under jni/prebuild/include/<ABI>/
