1、废话linux

最近学习,第一步就是编译.咱们须要编译FFmpag,x264,fdk_aac，下面是x264,网上说的不少都是几百年前的，我亲测完美可用android

仍是那句话我能力有限，可是我但愿我写的东西可以让更多的人可以接受.我也是刚刚接触.作一个记录，也但愿可以对其余人有好处.
联系我能够直接评论，也能够加我QQ：2519687025git

2、干货

准备：1.fdk_aac的源码 git clone https://android.googlesource.com/platform/external/aaceclipse

3.须要下载cmake 直接在cmd里面就能够了,以前的FFmpeg和x264都是cygwin里面的.如今不用.须要设置cmake环境变量,加入到path里面ide

4.编译脚本.这个脚本本身去理解吧.我也是只知其一;不知其二--脚本名称：CMakeLists.txt学习

3、编译ui

这个的编译相对简单，只要下载cmake就能够了.直接cmake就能够了.google

1 .定位到编译目录

2.执行cmake 命令
cmake -G "MinGW Makefiles" -DCMAKE_SYSTEM_NAME=Andr
oid -DFDK_AAC_SOURCE_DIR="E:/soft/source/fdk_aac/aac" E:\qupai_code_eclipse\code
\ThirdParty\Build\fdk-aac -DCMAKE_MAKE_PROGRAM=E:\android-ndk-r9c\prebuilt\windo
ws\bin\make.exeidea

3 .cmake --bulid . -- -j8

注意：DFDK_AAC_SOURCE_DIR="你的fdk_aac的源码地址" spa

E:\qupai_code_eclipse\code\ThirdParty\Build\fdk-aac ----这里是你的CMakeLists.txt地址
