编译x264和FAAC

关于

x264
FAAC

编译x264源码

git clone git://git.videolan.org/x264.git
如果没有git请先安装git
apt-get install git

vim android_build.sh

#!/bin/bash
NDK_ROOT=/ndk_build/android-ndk-r14b
SYSROOT=$NDK_ROOT/platforms/android-9/arch-arm/
TOOLCHAIN=$NDK_ROOT/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
function build_one
{
 ./configure \
    --prefix=$PREFIX \
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    --sysroot=$SYSROOT \
    --host=arm-linux \
    --enable-pic \
    --enable-static \
    --disable-asm \
    --disable-shared \
    --disable-cli
    make clean
    make
    make install
}
CPU=arm
PREFIX=$(pwd)/android/$CPU  
build_one

然后执行

chmod 777 android_build.sh
./android_build.sh

会得到一个android文件夹，在这个文件夹中即有我们需要的东西。

编译FAAC

wget https://ncu.dl.sourceforge.net/project/faac/faac-src/faac-1.28/faac-1.28.tar.gz

下载解压

make
cp ./libfaac/.libs/*.a $PREFIX/lib
cp ./libfaac/.libs/*.so $PREFIX/lib
cp ./include/*.h $PREFIX/include

执行脚本，NDK_ROOT注意改成自己的。
