Intenté agregar el soporte de lifdk-aac a ffmpeg compilado para Android. Para ello utilicé:
LINKER_LIBS="$LINKER_LIBS -lfdk-aac"
cd fdk-aac
ADDITIONAL_CONFIGURE_FLAG="$ADDITIONAL_CONFIGURE_FLAG --enable-libfdk-aac"
export PKG_CONFIG_LIBDIR=$(pwd)/$PREFIX/lib/pkgconfig/
export PKG_CONFIG_PATH=$(pwd)/$PREFIX/lib/pkgconfig/
./configure \
--prefix=$(pwd)/$PREFIX \
--host=$HOST \
--disable-shared \
--enable-static \
--with-pic \
$ADDITIONAL_CONFIGURE_FLAG \
|| exit 1
make clean || exit 1
make -j${JOBS} install || exit 1
cd ..
Y finalmente para ffmpeg usé:
LINKER_LIBS="$LINKER_LIBS -lavcodec -lavformat -lavresample -lavutil -lswresample -lswscale"
PKG_CONFIG=${CROSS_COMPILE}pkg-config
if [ ! -f $PKG_CONFIG ];
then
cat > $PKG_CONFIG << EOF
#!/bin/bash
pkg-config \$*
EOF
chmod u+x $PKG_CONFIG
fi
cd ffmpeg
export PKG_CONFIG_LIBDIR=$(pwd)/$PREFIX/lib/pkgconfig/
export PKG_CONFIG_PATH=$(pwd)/$PREFIX/lib/pkgconfig/
./configure --target-os=linux \
--prefix=$PREFIX \

Se compila sin errores. Pero cuando intento reproducir un archivo .aac, no se escucha bien. Utilicé 3.4.2 fuentes ffmpeg, la última versión de libfdk-aac, ndk r10e, gcc 4.9.
¿Alguna pista? Gracias.
