基础编译，请参考上一篇文章：

如果想编译静态ffmpeg可执行文件，编译脚本如下：

#!/bin/bash

export TMPDIR=/Users/aivensmac/work/project/ffmpeg/armbuild/tmp

NDK=/Users/aivensmac/Library/Android/android-ndk-r13b

SYSROOT=$NDK/platforms/android-16/arch-arm/

TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64

CPU=arm

PREFIX=/Users/aivensmac/work/project/ffmpeg/armbuild/bin

ADDI_CFLAGS="-marm"

function build_one

{

./configure \

--prefix=$PREFIX \

--pkg-config-flags="--static" \

--extra-cflags="-I$PREFIX/include -static" \

--extra-ldflags="-L$PREFIX/lib -static" \

--disable-shared \

--enable-static \

--disable-doc \

--enable-ffmpeg \

--disable-ffplay \

--disable-ffprobe \

--disable-ffserver \

--disable-doc \

--disable-symver \

--enable-small \

--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \

--target-os=linux \

--arch=arm \

--enable-cross-compile \

--sysroot=$SYSROOT \

$ADDITIONAL_CONFIGURE_FLAG

make clean

rm build.log

make -j4 | tee build.log

make install

}

build_one

编译出来的ffmpeg文件大小为11m左右，这个放在android上运行还是太大，下一篇会提供精简过的ffmpeg编译脚本。
