集成ffmpeg/x264:ERROR: libx264 not found的问题

在配置的时候，要注意一下NDK的安装路径，替换成自己NDK的安装路径。
x264的编译脚本内容为：

export NDK=/home/cmake/Android/Sdk/ndk-bundle
export PLATFORM=$NDK/platforms/android-18/arch-arm/
export TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
export PREFIX=./android/arm

function build_one
{
  ./configure   --prefix=$PREFIX --enable-static \
  --enable-pic \
  --host=arm-linux \
  --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \
  --sysroot=$PLATFORM

  make clean
  make -j 4
  make install
}

build_one

echo Android ARM builds finished

ffmpeg的编译脚本为：

#!/usr/bin/env bash  

export NDK=/Users/pingzhang/Documents/tool/android-ndk-r1  
#这下面的架构要与x264的架构保持一致  
export PREBUILT=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/darwin-x86_64   
export PLATFORM=$NDK/platforms/android-23/arch-arm    
export PREFIX=$NDK/sources/ffmpeg/android
