压缩tar zip文件&＃xff1a;
tar czvf ffmpeg_3.4.1.tar ffmpeg
zip -r ffmpeg_3.4.1.zip ./ffmpeg

1.安装yasm
sudo apt-get install yasm
sudo apt-get install git

2.下载FFmpeg
git clone https://git.ffmpeg.org/ffmpeg.git

3.配置NDK环境
解压tar包&＃xff1a;tar -xzvf  **.tar.gz
解压zip包&＃xff1a;unzip *.zip
/home/desaco/Desktop/source_compile/envir_jdk_ndk_sdk/android-ndk-r13
/home/desaco/Desktop/source_compile/envir_jdk_ndk_sdk/android-sdk-linux
/home/desaco/Desktop/source_compile/envir_jdk_ndk_sdk/jdk1.8.0_144

vim ~/.bashrc(sudo gedit /.bashrc)
export NDK&＃61;"/home/desaco/Desktop/source_compile/envir_jdk_ndk_sdk/android-ndk-r13"
export PATH&＃61;$NDK:$PATH
source ~/.bashrc

4.新建build_shell.sh文件&＃xff0c;并写入脚本内容
touch build_shell.sh
sudo gedit /build_shell.sh&＃xff08;将脚本写入build_shell.sh文件中&＃xff0c;直接打开时没有内容的&＃xff09;
重新打开需要命令sudo gedit /build_shell.sh&＃xff0c;才能看到文件里有内容
#!/bin/bash
make clean
export NDK&＃61;/home/desaco/Desktop/source_compile/envir_jdk_ndk_sdk/android-ndk-r13
export SYSROOT&＃61;$NDK/platforms/android-9/arch-arm/
export TOOLCHAIN&＃61;$NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64
export CPU&＃61;arm
export PREFIX&＃61;$(pwd)/android/$CPU
export ADDI_CFLAGS&＃61;"-marm"
./configure --target-os&＃61;linux \

--extra-ldflags&＃61;"$ADDI_LDFLAGS" \
$ADDITIONAL_CONFIGURE_FLAG
make clean
make
make install

5.修改FFmpeg执行权限和ndk执行权限
shell脚本执行,会关联许多文件,需要文件有可以执行的权限: 
chmod 777 -R ffmpeg&＃xff1b;
chmod 777 -R ndk

6.修改配置文件,FFmpeg根目录下的configure文件 sudo gedit /configure
#SLIBNAME_WITH_MAJOR&＃61;&＃39;$(SLIBNAME).$(LIBMAJOR)&＃39;
#LIB_INSTALL_EXTRA_CMD&＃61;&＃39;
(RANLIB) "$(LIBDIR)/$(LIBNAME)"&＃39; #SLIB_INSTALL_NAME&＃61;&＃39;$(SLIBNAME_WITH_VERSION)&＃39; #SLIB_INSTALL_LINKS&＃61;&＃39;$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)&＃39;  将以上几行注释,修改成下面几行-> #jmodified SLIBNAME_WITH_MAJOR&＃61;&＃39;$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)&＃39; LIB_INSTALL_EXTRA_CMD&＃61;&＃39;
(RANLIB) "$(LIBDIR)/$(LIBNAME)"&＃39; #SLIB_INSTALL_NAME&＃61;&＃39;$(SLIBNAME_WITH_VERSION)&＃39; #SLIB_INSTALL_LINKS&＃61;&＃39;$(SLIBNAME_WITH_MAJOR) $(SLIBNAME)&＃39;  将以上几行注释,修改成下面几行-> #jmodified SLIBNAME_WITH_MAJOR&＃61;&＃39;$(SLIBPREF)$(FULLNAME)-$(LIBMAJOR)$(SLIBSUF)&＃39; LIB_INSTALL_EXTRA_CMD&＃61;&＃39;
(RANLIB)"$(LIBDIR)/$(LIBNAME)"&＃39;
SLIB_INSTALL_NAME&＃61;&＃39;$(SLIBNAME_WITH_MAJOR)&＃39;
SLIB_INSTALL_LINKS&＃61;&＃39;$(SLIBNAME)&＃39;

7.执行shell脚本
chmod 777 build_shell.sh
./build_shell.sh

-- Linux编译还是不行&＃xff0c;改了格式还是不行&＃xff1f;
ffmpeg build_ff_android.sh编译出现No such file or directory错误&＃xff1a;原因&＃xff1a;在windows中写好shell脚本测试正常&＃xff0c;但是上传到 Linux 上以脚本方式运行命令时提示No such file or directory错误&＃xff0c;那么一般是文件格式是dos格式的缘故&＃xff0c;改成unix 格式即可。
【解决办法一】&＃xff1a;
重新设置下文件格式&＃xff08;在命令模式下&＃xff09;&＃xff1a;sudo vim build_ff_android.sh
:set ff&＃61;unix  
保存退出:
:wq  
 再执行&＃xff0c;就可以了。

【解决方法二】
如果linux系统已安装了dos2unix服务&＃xff0c;可以直接执行&＃xff1a;
dos2unix {filename}
apt install dos2nuix
dos2unix build_ff_android.sh
这样就将dos格式的文件转换为linux平台下的文件。

sudo apt-get install tofrodos
实际上它安装了两个工具&＃xff1a;todos&＃xff08;相当于unix2dos&＃xff09;&＃xff0c;和fromdos&＃xff08;相当于dos2unix&＃xff09;。
dos2unix build_ff_android.sh

sudo chmod &＃43;x build_ff_android.sh
./build_ff_android.sh
