一、centos linux下装置ffmpeg

1、下载解压

wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gztar -zxvf ffmpeg-3.1.tar.gz

2、 进入解压后目录,输出如下命令/usr/local/ffmpeg为本人指定的装置目录

cd ffmpeg-3.1./configure --prefix=/usr/local/ffmpegmake && make install

3、配置变量
vi /etc/profile
在最初PATH增加环境变量：
export PATH=$PATH:/usr/local/ffmpeg/bin
保留退出
查看是否失效
source /ect/profile 或者 . /etc/profile 设置失效
4、查看版本
ffmpeg -version 查看版本

留神：

若装置过程中呈现以下谬误：

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 latestversion from Git. If the latest version fails, report the problem to theffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.Include the log file “config.log” produced by configure as this will helpsolve the problem.

须要装置 yasm

wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gztar -zxvf yasm-1.3.0.tar.gzcd yasm-1.3.0./configuremake && make install
sudo yum -y install gccsudo yum -y install gcc-c++gcc -v
sudo apt-get install cmakecmake -version或者wget https://cmake.org/files/v3.7/cmake-3.7.2.tar.gztar -zxvf cmake-3.7.2.tar.gzcd cmake-3.7.2/./bootstrap       //此步可能遇到问题，见下文gmake             //此步须要很长时间gmake install
yum install openssl-develyum install SDL-devel
#国内用户举荐从同步镜像网站gitee下载 git clone --depth 1 https://gitee.com/xia-chu/ZLMediaKitcd ZLMediaKit#千万不要遗记执行这句命令git submodule update --init
cd ZLMediaKitmkdir buildcd build#macOS下可能须要这样指定openss门路：cmake .. -DOPENSSL_ROOT_DIR=/usr/local/Cellar/openssl/1.0.2j/cmake ..make -j4
