实测好使， ffmpeg x264 编码器包含，编译了好久， 一直编译不进去，现用
ff3.3–ijk0.8.0–20170518–001 版本的ffmpeg和x264-snapshot-20151028-2245 版本的x264编译成功
转载如下， 非常感谢该作者，帮助非常大，留以备用

在主目录下新建init-android-x264.sh

#! /usr/bin/env bash

IJK_x264_UPSTREAM=http://git.videolan.org/git/x264.git
IJK_x264_FORK=http://git.videolan.org/git/x264.git

IJK_x264_LOCAL_REPO=extra/x264

set -e
TOOLS=tools

echo “== pull x264 base ==”
sh $TOOLS/pull-repo-base.sh $IJK_x264_UPSTREAM $IJK_x264_LOCAL_REPO

function pull_fork()

echo “== pull x264 fork $1 ==”
sh $TOOLS/pull-repo-ref.sh $IJK_x264_FORK android/contrib/x264-$1 ${IJK_x264_LOCAL_REPO}
}

pull_fork “armv5”
pull_fork “armv7a”
pull_fork “arm64”
pull_fork “x86”
pull_fork “x86_64”

这步执行完后，会在extra下面有个x264， 下面有源码
并且在android/contrib下面会有x264-armv7a等五个文件夹，如下

x264.png

在android/contrib下新建compile-x264.sh 和 tools/do-compile-x264.sh

compile-x264.sh

with libx264

这里我把-enable-encoder=libx264开启了，但是module.sh却还是把encoder全部disable了，只开启了aac，所以还要修改一下module.sh
