#添加了cflags 和 ldflags 的路径 libx264路径找到安装/usr/local/include已经变移到系统 frei0r：/Users/zd/androidStudio/ndk/android-ndk-r10e/platforms/android-16/arch-arm/usr/include 头文件丢到了里面

#单独执行frei0r的 configure文件后把里面的frei0r.h文件放入ndk对应的platforms api ex:android-ndk-r10e/platforms/android-16/arch-arm/usr/include下面这里的android版本与上面 NDK_PLATFORM_VERSION 对应
#并且此目录下的math.h文件下函数后缀 __NDK_FPABI_MATH __pure2去掉了
#makefile 的文件加入了pie
#only position independent executables (PIE) are supported
#LOCAL_CFLAGS += -pie -fPIE
#LOCAL_LDFLAGS += -pie -fPIE
#libx264 ./configure --enable-static
#在 /ffmpeg/libavfilter/下的 vf_frei0r.c 里面的frei0r_init函数包含外部滤镜引入路径名称：frei0r_pathlist
#修改这个替换so文件所在路径

ps:作为后期学习资料，不喜勿喷
