使用NDK交叉编译ffmpeg, android后台可执行

1，编译fdk-aac
 
wget -O fdk-aac.zip https://github.com/mstorsjo/fdk-aac/zipball/master
 
unzip fdk-aac.zip
 
cd mstorsjo-fdk-aac*
 
autoreconf -fiv
 
使用如下的配置文件
 
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  \
 
  CXX=/opt/android-ndk-toolchain/bin/arm-linux-androideabi-g++ \
 
  --host=arm-linux \
 
  --enable-static \
 
然后
 
Make
 
Make installl
 
2,编译libx264
 
wget
 
tar xjvf last_x264.tar.bz2
 
cd x264-snapshot*
 
使用如下confiure
 
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 ARM_TOOL=/home/zangcf/cross_compile/android-ndk-r9b/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
 
export ARM_LIBO=/home/zangcf/cross_compile/android-ndk-r9b/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.8
 
export PATH=$ARM_TOOL/bin:$PATH
 
export ARM_PRE=arm-linux-androideabi
 
 
 
 
 
./configure --prefix=/home/zangcf/ffmpeg/ffmpeg_arm/ffmpeg_build \
 
        --extra-cflags=" -I$ARM_INC -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fstack-protector -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__  -Wno-psabi -march=armv5te -mtune=xscale -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -DANDROID  -Wa,--noexecstack -MMD -MP " \
 
        --extra-ldflags="  -nostdlib -Bdynamic  -Wl,--no-undefined -Wl,-z,noexecstack  -Wl,-z,nocopyreloc -Wl,-soname,/system/lib/libz.so -Wl,-rpath-link=$ARM_LIB,-dynamic-linker=/system/bin/linker -L$ARM_LIB -nostdlib $ARM_LIB/crtbegin_dynamic.o $ARM_LIB/crtend_android.o -lc -lm -ldl -lgcc " \
 
        --cross-prefix=${ARM_PRE}- --disable-asm --host=arm-linux
 
 
 
make
 
make install
 
make distclean
 
 
 
2, 下载编译libvpx
 
wget
 
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
 
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
 
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 ARM_TOOL=/home/zangcf/cross_compile/android-ndk-r9b/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64
 
export ARM_LIBO=/home/zangcf/cross_compile/android-ndk-r9b/toolchains/arm-linux-androideabi-4.8/prebuilt/linux-x86_64/lib/gcc/arm-linux-androideabi/4.8
 
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 \
 
--arch=armv5te \
 
--enable-cross-compile \
 
--cc=$ARM_TOOL/bin/${ARM_PRE}-gcc \
 
--cross-prefix=$ARM_TOOL/bin/${ARM_PRE}- \
 
--extra-cflags=" -fPIC -DANDROID -fpic -mthumb-interwork -ffunction-sections -funwind-tables -fstack-protector -fno-short-enums -D__ARM_ARCH_5__ -D__ARM_ARCH_5T__ -D__ARM_ARCH_5E__ -D__ARM_ARCH_5TE__  -Wno-psabi -march=armv5te -mtune=xscale -msoft-float -mthumb -Os -fomit-frame-pointer -fno-strict-aliasing -finline-limit=64 -D

/////////////////////////////////////////////////////////////////////
 
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
 
export ARM_ROOT=/home/zangcf/cross_compile/android-ndk-r9b
