—下载FFmpeg3.4库— ffmpeg-download.sh
—下载fdkaac音频编码库— http://www.linuxfromscratch.org/blfs/view/svn/multimedia/fdk-aac.html
—下载x264视频编码库— git clone git://git.videolan.org/x264.git
—下载NDK开发包Android专用— https://developer.android.google.cn/ndk/downloads/index.html
下面是音视频编解码分开的，脚本大部分一致
iOS --纯解码— ffmpeg-iOS-build.sh：需要和FFmpeg3.4处于同一目录
—音频编码— build_fdkaac_iOS.sh：编译出fdkaac静态库 build_ffmpeg_iOS_fdkaac.sh 编译FFmpeg可以音频编解码的库
—视频编码编码— build_x264_iOS.sh：编译出x264静态库静态库 build_ffmpeg_iOS_x264.sh 编译出FFmpeg可以视频编解码的库
—注意—
1、脚本中的路径更换
2、gas-preprocessor.pl拷贝到mac电脑 /usr/local/bin目录下
执行chmod 777 /usr/local/bin/gas-preprocessor.pl
3、引入什么库，加入路径即可
--extra-cflags=“-I/头文件路径”
--extra-ldflags=“-L/库文件路径” \
Android
—下载NDK开发包— —FFmpeg为c/c++库，需要构建NDK环境—
--纯解码— ffmpeg-Android-build.sh：注意FFmpeg3.4的路径
—音频编码— build_fdkaac_android.sh：编译出x264静态库静态库 build-ffmpeg-armeabi-fdkaac.sh 编译出FFmpeg可以音频编解码的库
—视频编码编码— build_x264_android.sh：编译出x264静态库静态库 build-ffmpeg-armeabi-x264.sh 编译出FFmpeg可以视频编解码的库
—NDK环境搭建— 1、创建工程时需要选择c++支持 2、将编译好的库放在main目录下: main/jniLibs/(armeabi和include) 3、库引入->CmakeLists.txt->加入此行下面即可：cmake_minimum_required(VERSION 3.4.1)
# FFMpeg配置

set(distribution_DIR ${CMAKE_SOURCE_DIR}/../../../../src/main/jniLibs)

# 滤镜特效处理库
add_library(

IMPORTED)
set_target_properties(
avfilter

../../../../src/main/jniLibs/armeabi/libavfilter.so)
# 封装格式处理库
add_library(

add_library(

add_library(

#set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=gnu++11")
#判断编译器类型,如果是gcc编译器,则在编译选项中加入c++11支持
if(CMAKE_COMPILER_IS_GNUCXX)
set(CMAKE_CXX_FLAGS "-std=c++11 ${CMAKE_CXX_FLAGS}")
message(STATUS "optional:-std=c++11")
endif(CMAKE_COMPILER_IS_GNUCXX)
#配置编译的头文件
include_directories(src/main/jniLibs/include)
# Creates and names a library, sets it as either STATIC
# or SHARED, and provides the relative paths to its source code.
# You can define multiple libraries, and CMake builds them for you.
# Gradle automatically packages shared libraries with your APK.
add_library( # Sets the name of the library.
native-lib
# Sets the library as a shared library.
SHARED
# Provides a relative path to your source file(s).
src/main/cpp/native-lib.cpp )
此处加入：avcodec avdevice avfilter avformat avutil postproc swresample swscale
如下：
target_link_libraries( # Specifies the target library.
native-lib avcodec avdevice avfilter avformat avutil postproc swresample swscale
# Links the target library to the log library
# included in the NDK.
${log-lib} )
4、build.gradle文件配置
externalNativeBuild {
cmake {
cppFlags "-frtti -fexceptions"
abiFilters 'armeabi'
}
