概述
之前记录过ffmpeg相关的移植内容，最近有人问我，关于64位的问题，笔者今天抽空重新编译了一下**ffmpeg-3.4.6**版本的32位和64位的静态库，基于cmake来进行编译链接，中间有一些坑，记录一下。
环境配置
系统：ubuntu 16.04
ndk版本：android-ndk-r15c
fdk-aac版本：0.1.6
x264版本：最新的stable版本
固定的配置脚本：config.sh，根据你自己的环境变量，变更一下NDK的路径

考虑到现在的ndk开发，基本都是基于android-studio的cmake来完成，而基于动态库的实现比较简单，之前博客也有，这里记录一下，基于静态库来编译链接最终的so库
这里以ffmpeg-stream-mp4工程为例，CMakeLists.txt内容如下
cmake_minimum_required(VERSION 3.4.1)add_library(native-stream SHARED src/main/cpp/native_stream.cpp src/main/cpp/mp4_stream.cpp)#获取上级目录get_filename_component(PARENT_DIR ${CMAKE_SOURCE_DIR} PATH)set(LIBRARY_DIR ${PARENT_DIR}/common-static)set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")set(CMAKE_VERBOSE_MAKEFILE on)add_library(avcodec STATIC IMPORTED)set_target_properties(avcodec PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libavcodec.a )add_library(avdevice STATIC IMPORTED)set_target_properties(avdevice PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libavdevice.a )add_library(avfilter STATIC IMPORTED)set_target_properties(avfilter PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libavfilter.a )add_library(avformat STATIC IMPORTED)set_target_properties(avformat PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libavformat.a )add_library(avresample STATIC IMPORTED)set_target_properties(avresample PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libavresample.a )add_library(avutil STATIC IMPORTED)set_target_properties(avutil PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libavutil.a )add_library(postproc STATIC IMPORTED)set_target_properties(postproc PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libpostproc.a )add_library(swresample STATIC IMPORTED)set_target_properties(swresample PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libswresample.a )add_library(swscale STATIC IMPORTED)set_target_properties(swscale PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libswscale.a )add_library(fdk-aac STATIC IMPORTED)set_target_properties(fdk-aac PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libfdk-aac.a )add_library(x264 STATIC IMPORTED)set_target_properties(x264 PROPERTIES IMPORTED_LOCATION ${LIBRARY_DIR}/libs/${ANDROID_ABI}/lib/libx264.a )#头文件include_directories(${LIBRARY_DIR}/libs/${ANDROID_ABI}/include)#静态库一定要注意下面的链接顺序，否则会报错target_link_libraries(native-stream avformat avdevice avfilter avcodec avutil postproc swresample avresample swscale x264 fdk-aac z c m dl log)这里要注意：静态库链接的顺序很重要！！！
