本文介绍了FFmpeg的功能与用途，包括视频采集、格式转换、抓图及加水印等功能。详细展示了FFmpeg在云服务器集群上的编译过程，涉及NDK安装、环境配置及shell脚本使用等内容。
如何在云服务器集群中编译FFmpeg？
上传NDK(android-ndk-r10e-linux-x86_64.bin )、FFmpeg
NDK安装
目录给权限：chmod 777 -R ndk
解压：./android-ndk-r10e-linux-x86_64.bin
环境变量配置：
命令vim ~/.bashrc
添加：
export NDKROOT=/usr/ndk/android-ndk-r10e
export PATH=$NDKROOT:$PATH
更新环境变量：
source ~/.bashrc
1）编写 .android_build .shshell脚本文件
2）给文件权限：chmod 777 android_build.sh
dos2unix
3）执行 ./android_build.sh
譬如:
[root@iZ94s4ycnl7Z FFmpeg]# ./configure
yasm/nasm not found or too old. Use --disable-yasm for a crippled build.
If you think configure made a mistake, make sure you are using the latest
version from Git. If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.
[root@iZ94s4ycnl7Z FFmpeg]#
[root@iZ94s4ycnl7Z FFmpeg]# ./configure --disable-yasm
install prefix /usr/local
