echo "OK, merge done!"

修改SDK的路径和SDK的版本, 然后编译, 因为我已经手动下载了x264, 所以就把git clone git://git.videolan.org/x264.git x264这句注释掉

保存这位build_x264.sh, cd到build_x264.sh目录下, 然后执行./build_x264.sh, 如果没有权限, 先执行chmod 777 ./build_x264.sh

最后生成的x264库在x264目录/install/iPhoneOS里

X264_LIB 是前面编译的x264库的路径

这边ffmpeg使用的版本是2.6, 保存, 然后执行…

最后生成的库文件在build/iPhoneOS里
