1.在https://ffmpeg.org/中下載ffmpeg源碼(目前版本為ffmpeg-3.2.1)

2.下載ndk

3.分別解壓ffmpeg和ndk， 路徑如 ：

ffmpeg路徑：

/home/lx/Downloads/ffmpeg-3.2.1

ndk路徑：

/home/lx/Downloads/android-ndk-r13b

4.替換ffmpeg-3.2.1/configure 中的

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)'

為 ：

SLIBNAME_WITH_MAJOR='$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)'

LIB_INSTALL_EXTRA_CMD='$$(RANLIB)"$(LIBDIR)/$(LIBNAME)"'

SLIB_INSTALL_NAME='$(SLIBNAME_WITH_MAJOR)'

SLIB_INSTALL_LINKS='$(SLIBNAME)'

5.在ffmpeg-3.2.1/目錄下創建一個build_android文件，內容為

#!/bin/bash

NDK=/home/lx/Downloads/android-ndk-r13b

SYSROOT=$NDK/platforms/android-19/arch-arm/

TOOLCHAIN=$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64

CPU=arm

ARCH=arm

PREFIX=$(pwd)/android/$CPU

ADDI_CFLAGS="-marm"

export NDK

export SYSROOT

export TOOLCHAIN

#注意下面的 \ 后面不要帶空格

./configure \

--prefix=$PREFIX \

--arch=$ARCH \

--cross-prefix=$TOOLCHAIN/bin/arm-linux-androideabi- \

--extra-ldflags="$ADDI_LDFLAGS" \

--sysroot=$SYSROOT \

--extra-cflags="-Os -fpic $ADDI_CFLAGS" \

--target-os=linux \

--enable-cross-compile \

--enable-gpl \

--enable-shared \

--disable-static \

--disable-doc \

--enable-small \

--disable-programs \

--disable-ffmpeg \

--disable-ffplay \

--disable-ffprobe \

--disable-ffserver \

$ADDITIONAL_CONFIGURE_FLAG

make

make install

6.在命令行下添加可執行權限 chmod +x ?build_android

7.在命令行下執行 ./build_android

8.生成的lib和include在?ffmpeg-3.2.1/如下 目錄下

lx@ubt:~/Downloads/ffmpeg-3.2.1/android/arm$ ls

include lib

lx@ubt:~/Downloads/ffmpeg-3.2.1/android/arm/include$ ls

libavcodec libavdevice libavfilter libavformat libavutil libpostproc libswresample libswscale

lx@ubt:~/Downloads/ffmpeg-3.2.1/android/arm/lib$ ls

libavcodec-57.so libavdevice-57.so libavfilter-6.so libavformat-57.so libavutil-55.so libpostproc-54.so libswresample-2.so libswscale-4.so pkgconfig

libavcodec.so libavdevice.so libavfilter.so libavformat.so libavutil.so libpostproc.so libswresample.so libswscale.so
