上篇这个说道window下混编android的ffmpeg包，但是想接入x264,fdk-acc,lame还是需要注意很多细节的，x264是视频的编码包，fdk-acc是acc编码包，lame是mp3的编码包。步骤肯定是先编译每个模块成功后，才做整体的编译，不然直接整体编译，都不好调试
那下面就分别和总体说明编译的脚本
环境
环境是在window下的bash环境，参照上方的链接，在window中搭建linux的子系统，然后访问window的硬盘空间可以/mnt/+硬盘，比如说D盘：/mnt/d/
x264编译
编译的脚本：

#!/bin/bash
NDK=/mnt/d/IdeSDK/ndk/android-ndk-r14b-linux
SYSROOT=$NDK/platforms/android-14/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64

CPU=armv7-a
PREFIX=$(pwd)/android/$CPU
ADDI_CFLAGS=""
ADDI_LDFLAGS=""
function build_x264
{
./configure \
    --prefix=$PREFIX \
    --disable-asm \
    --enable-static \
    --enable-shared \
    --enable-pic \
    --enable-strip \
    --host=arm-linux-androideabi \
    --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
    --sysroot=$SYSROOT
    --extra-cflags="-Os -fpic $ADDI_CFLAGS $OPTIMIZE_CFLAGS" \
    --extra-ldflags="$ADDI_LDFLAGS" \
    $ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install
}
build_x264

要注意的是,下面两句要加上，因为我要用子模块的静态库编译去编译一个总的ffmepg.so动态库

    --extra-cflags="-Os -fpic $ADDI_CFLAGS $OPTIMIZE_CFLAGS" \
    --extra-ldflags="$ADDI_LDFLAGS" \

fdk-acc 编译

#!/bin/bash
NDK=/mnt/d/IdeSDK/ndk/android-ndk-r14b-linux
SYSROOT=$NDK/platforms/android-14/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
CPU=armv7-a
PREFIX=$(pwd)/android/$CPU
PLATFORM=$NDK/platforms/android-14/arch-arm
CROSS_COMPILE=$TOOLCHAIN/bin/arm-linux-androideabi-
CFLAGS=""
FLAGS="--enable-static  --host=$HOST --target=android --disable-asm "

export CXX="${CROSS_COMPILE}g++ --sysroot=${SYSROOT}"
export LDFLAGS=" -L$SYSROOT/usr/lib  $CFLAGS "
export CXXFLAGS=$CFLAGS
export CFLAGS=$CFLAGS
export CC="${CROSS_COMPILE}gcc --sysroot=${SYSROOT}"
export AR="${CROSS_COMPILE}ar"
export LD="${CROSS_COMPILE}ld"
export AS="${CROSS_COMPILE}gcc"
function build_acc
{
./configure \
    --prefix=$PREFIX \
    --disable-asm \
    --enable-static \
    --enable-shared \
    --target=android \
    --enable-pic \
    --enable-strip \
    --host=arm-linux-androideabi \
$ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install
}
build_acc

编译acc的时候，花了好多时间，因为它跟x264的编译方式不是一门路，不用在configure 中配置交叉混编的参数，而是通过设置环境变量的参数来做的，即设置一系列的环境变量

export LDFLAGS=" -L$SYSROOT/usr/lib  $CFLAGS "
export CXXFLAGS=$CFLAGS
export CFLAGS=$CFLAGS
...

lame编译

#!/bin/bash
NDK=/mnt/d/IdeSDK/ndk/android-ndk-r14b-linux
SYSROOT=$NDK/platforms/android-14/arch-arm/
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
HOME=$(dirname "$PWD")
CPU=armv7-a
PREFIX=$(pwd)/android/$CPU

CROSS_PREFIX=$TOOLCHAIN/bin/arm-linux-androideabi-
export CC="${CROSS_PREFIX}gcc --sysroot=${SYSROOT}"
export LD="${CROSS_PREFIX}ld"
export RANLIB="${CROSS_PREFIX}ranlib"
export STRIP="${CROSS_PREFIX}strip"
export READELF="${CROSS_PREFIX}readelf"
export OBJDUMP="${CROSS_PREFIX}objdump"
export ADDR2LINE="${CROSS_PREFIX}addr2line"
export AR="${CROSS_PREFIX}ar"
export AS="${CROSS_PREFIX}as"
export CXX="${CROSS_PREFIX}g++"
export OBJCOPY="${CROSS_PREFIX}objcopy"
export ELFEDIT="${CROSS_PREFIX}elfedit"
export CPP="${CROSS_PREFIX}cpp --sysroot=${SYSROOT}"
export DWP="${CROSS_PREFIX}dwp"
export GCONV="${CROSS_PREFIX}gconv"
export GDP="${CROSS_PREFIX}gdb"
export GPROF="${CROSS_PREFIX}gprof"
export NM="${CROSS_PREFIX}nm"
export SIZE="${CROSS_PREFIX}size"
export STRINGS="${CROSS_PREFIX}strings"
function build_lame
{
./configure \
    --with-pic \
    --prefix=$PREFIX \
    --bindir="$HOME/bin" \
    --enable-nasm \
    --enable-static \
    --enable-shared \
    --host=arm-linux \
    --with-sysroot=$SYSROOT
    $ADDITIONAL_CONFIGURE_FLAG
   #make clean
   #make
   #make install
}
build_lame

这句代码记得加上，--bindir="$HOME/bin" \，另外lame跟acc编译方案类似，采用export配置环境变量的方式去编译脚本

ffmpeg编译脚本
最后是总的ffmpeg的编译脚本，需要注意的是，设置上面x264,acc,lame的头文件和外部包地址：

    --extra-cflags="-I$FDK_INCLUDE -I$X264_INCLUDE -I$LAME_INCLUDE" \
    --extra-ldflags="-L$FDK_LIB -L$X264_LIB -L$LAME_LIB" \

这样才能识别到子模块编译的包，打开--enable-gpl \状态
总体脚本如下

#!/bin/bash
# 设置临时文件夹，需要提前手动创建
#export TMPDIR="/home/yangle/ffmpeg/ffmpeg-4.0/ffmpegtemp"
# 设置NDK路径 D:\IdeSDK\ndk\android-ndk-r14b-linux
NDK=/mnt/d/IdeSDK/ndk/android-ndk-r14b-linux
# 设置编译针对的平台，可以根据自己的需求进行设置
# 当前设置为最低支持android-14版本，arm架构
SYSROOT=$NDK/platforms/android-14/arch-arm/
# 设置编译工具链，4.9为版本号
TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64

# 设置编译后的文件输出目录
