export PATH=$ARM_TOOL/bin:$PATH
export ARM_PRE=arm-linux-androideabi

--cross-prefix=${ARM_PRE}- --disable-asm --host=arm-linux
make
make install
make distclean
2, 下载编译libvpx
wget http://webm.googlecode.com/files/libvpx-v1.3.0.tar.bz2
tar xjvf libvpx-v1.3.0.tar.bz2
cd libvpx-v1.3.0
./configure --sdk-path=/home/zangcf/cross_compile/android-ndk-r9b --target=armv7-android-gcc \
--disable-runtime-cpu-detect \
--prefix=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build
Make
Make install
3, libogg
下载最新版本libogg-1.3.1.tar.gz，注意老版本会有问题。
使用如下configure
#!/bin/sh
BUILD_PATH=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build
CC_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-gcc
CPP_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-cpp
./configure \
--prefix=$BUILD_PATH \
--build=arm \
CC=$CC_PATH \
CPP=$CPP_PATH \
--host=arm-linux \
--enable-static \
Make
Make install
4，libvorbis
下载最新版本libvorbis-1.3.4.tar.gz，注意老版本可能会有问题
使用如下的configure
#!/bin/sh
BUILD_PATH=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build
CC_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-gcc
CPP_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-cpp
./configure \
--prefix=$BUILD_PATH \
--build=arm \
CC=$CC_PATH \
CPP=$CPP_PATH \
--host=arm-linux \
--enable-static \
Make
Make install
5，解决NDK交叉编译 selected processor does not support ARM mode libtheora的错误
下载最新的libtheora, wget http://downloads.xiph.org/releases/theora/libtheora-1.2.0alpha1.tar.gz
解压缩，然后使用如下configure来编译
#!/bin/sh
BUILD_PATH=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build
CC_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-gcc
CPP_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-cpp
./configure \
--prefix=$BUILD_PATH \
--build=arm \
CC=$CC_PATH \
CPP=$CPP_PATH \
--host=arm-linux \
--enable-static \
--with-ogg=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build \
AS=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-as \
AR=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-ar \
然后make，结果出现如下错误
selected processor does not support ARM mode
很多很多
通过对编译文件的仔细研究，发现只要加一个
--disable-asm
配置选项，就可以完全解决这个问题
6，下载lame-3.99.5
解压，然后使用如下配置文件配置
#!/bin/sh
BUILD_PATH=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build
CC_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-gcc
CPP_PATH=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-cpp
./configure \
--prefix=$BUILD_PATH \
--build=arm \
CC=$CC_PATH \
CPP=$CPP_PATH \
--host=arm-linux \
--enable-static \
AS=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-as \
AR=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-ar \
然后
Make
Make install
---libass 和libopus
4, 下载编译ffmpeg
wget http://ffmpeg.org/releases/ffmpeg-snapshot.tar.bz2
tar xjvf ffmpeg-snapshot.tar.bz2
cd ffmpeg
使用如下configure
export ARM_ROOT=/home/zangcf/cross_compile/android-ndk-r9b
export ARM_INC=$ARM_ROOT/platforms/android-8/arch-arm/usr/include/
export ARM_LIB=$ARM_ROOT/platforms/android-8/arch-arm/usr/lib/

export PATH=$ARM_TOOL/bin:$PATH
export ARM_PRE=arm-linux-androideabi
export LIB_INC=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build/include
export LIB_LIB=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build/lib
./configure --target-os=linux \

/////////////////////////////////////////////////////////////////////
执行configure的时候，怎么都提示找不到h264,经过仔细分析研读，分析configure文件，发现是x264的编译选项有问题，少了一个--enable-static
加上这个选项，重新编译x264,呵呵ffmpeg的配置编译都通过了。
make
make install
make distclean
hash -r
最后确定的configure需要增加很多解码工具，配置如下
