先讲一下编译FFMPEG及其配置
- 下载：
wget http://ffmpeg.org/releases/ffmpeg-2.6.9.tar.gz - 解压缩：
tar -xzf ffmpeg-2.6.9.tar.gz - 赋予权限：
chmod 777 -R ffmpeg-2.6.9 - 修改configure文件中的2775行开始的4行代码
改之前：
改之后：SLIBNAME_WITH_MAJOR='$(SLIBNAME).$(LIBMAJOR)' LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"' SLIB_INSTALL_NAME='$(SLIBNAME_WITH_VERSION)' SLIB_INSTALL_LINKS='$(SLIBNAME_WITH_MAJOR)$(SLIBNAME)'SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)' LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"' SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)' SLIB_INSTALL_LINKS='$(SLIBNAME)' - 编写build_android.sh
#!/bin/bash make clean export NDK=/ndk/android-ndk-r15 export SYSROOT=$NDK/platforms/android-9/arch-arm/ export TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64 export CPU=arm export PREFIX=$(pwd)/android/$CPU export ADDI_CFLAGS="-marm" ./configure --target-os=linux \ --prefix=$PREFIX --arch=arm \ --disable-doc \ --enable-shared \ --disable-static \ --disable-yasm \ --disable-symver \ --enable-gpl \ --disable-ffmpeg \ --disable-ffplay \ --disable-ffprobe \ --disable-ffserver \ --disable-doc \ --disable-symver \ --cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \ --enable-cross-compile \ --sysroot=$SYSROOT \ --extra-cflags="-Os -fpic $ADDI_CFLAGS" \ --extra-ldflags="$ADDI_LDFLAGS" \ $ADDITIONAL_CONFIGURE_FLAG make clean make make install - 赋予权限：
chmod 777 build_android.sh - 运行:
./build_android.sh - 新建android studio工程，将生成的android/arm/lib中的8个so文件，拷贝到libs\armeabi:
libavcodec-56.so libavdevice-56.so libavformat-56.so libavutil-54.so libpostproc-53.so libswresample-1.so libswscale-3.so - 在moudle 下的defaultConfig节点加入下面代码
sourceSets { main { jniLibs.srcDirs = ['libs'] } } externalNativeBuild { cmake { cppFlags "-frtti -fexceptions" abiFilters 'armeabi' } } - 将生成的android/arm/include整个文件夹，拷贝到as工程中的libs文件夹里面。
- 修改CMakeLists.txt文件：
cmake_minimum_required(VERSION 3.4.1)
add_library( native-lib
SHARED
src/main/cpp/native-lib.cpp )
find_library( log-lib
log )
include_directories(libs/include)
set(DIR ../../../../libs)
add_library(avcodec-56
SHARED
IMPORTED)
set_target_properties(avcodec-56
PROPERTIES IMPORTED_LOCATION
${DIR}/armeabi/libavcodec-56.so)
add_library(avdevice-56
SHARED
IMPORTED)
set_target_properties(avdevice-56
PROPERTIES IMPORTED_LOCATION
${DIR}/armeabi/libavdevice-56.so)
add_library(avformat-56

set_target_properties(avformat-56

add_library(avutil-54

set_target_properties(avutil-54

add_library(postproc-53

add_library(swscale-3

set_target_properties(swscale-3
PROPERTIES IMPORTED_LOCATION
${DIR}/armeabi/libswscale-3.so)
add_library(avfilter-5
SHARED
IMPORTED)
set_target_properties(avfilter-5
PROPERTIES IMPORTED_LOCATION
${DIR}/armeabi/libavfilter-5.so)
target_link_libraries( native-lib
avcodec-56
avdevice-56
avformat-56
avutil-54
postproc-53
swresample-1
swscale-3
avfilter-5
${log-lib} )
12.编译运行，如没出错，则说明编译配置正确
