linux下安装ffmpeg的详细教程
一、centos linux下安装ffmpeg
1、下载解压
wget http://www.ffmpeg.org/releases/ffmpeg-3.1.tar.gz
tar -zxvf ffmpeg-3.1.tar.gz
wget http://www.ffmpeg.org/releases/ffmpeg-4.4.tar.gz
tar -zxvf ffmpeg-4.4.tar.gz
2、 进入解压后目录,输入如下命令/usr/local/ffmpeg为自己指定的安装目录
cd ffmpeg-3.1
./configure --prefix=/usr/local/ffmpeg
make && make install
3、配置变量
vi /etc/profile
在最后PATH添加环境变量：
export PATH=$PATH:/usr/local/ffmpeg/bin
保存退出
查看是否生效
source /ect/profile 设置生效
4、查看版本
ffmpeg -version 查看版本
注意：
若安装过程中出现以下错误：
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 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.
需要安装 yasm
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar -zxvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
./configure
make && make install
二、debian 安装 ffmpeg
1、编辑/etc/apt/sources.list加入
deb http://www.deb-multimedia.org jessie main
复制
2、安装ffmpeg
sudo apt-get update
sudo apt-get install deb-multimedia-keyring
sudo apt-get install ffmpeg
```sh
#视频推rtmp
ffmpeg -re -i ./du.mp4 -c copy -f flv rtmp://127.0.0.1:1965/live/doorbell
#rtmp转视频
ffmpeg -i rtmp://127.0.0.1:1965/live/doorbell -vcodec h264 -f flv -acodec aac -ac 2 after.flv
ffmpeg -re -i ./du.mp4 -c copy -f flv rtmp://127.0.0.1:1965/rec/35a9728cbd5d17daf377d2d832b7d21a_22
#推送音频
ffmpeg -re -i ./Jm_ac1_ar441.wav -vcodec libx264 -preset:v ultrafast -tune:v zerolatency -f flv rtmp://127.0.0.1:1965/live/doorbell2
-acodec pcm_alaw
ffmpeg -re -i ./Jm_ac1_ar441.wav -acodec pcm_alaw -preset:v ultrafast -tune:v zerolatency -f flv rtmp://127.0.0.1:1965/live/doorbell2
centos7.x安装FFMPEG
安装依赖
yum install autoconf automake bzip2 bzip2-devel cmake freetype-devel gcc gcc-c++ git libtool make pkgconfig zlib-devel
安装编译yasm
mkdir /data/{src,service}
cd /data/src
wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
tar xf yasm-1.3.0.tar.gz
cd yasm-1.3.0/
./configure --enable-shared --prefix=/data/service/yasm
make
make install
–enable-shared是configure 常用的一个参数，表示启用动态库版本。
如果你要编译一个库的源代码，可以把它编译成静态库，也可以把它编译成动态库。如果你想编译成动态库，就用 –enable-shared参数；如果你想编译成静态库，就用–enable-static参数
安装编译ffmpeg
cd ..
wget http://www.ffmpeg.org/releases/ffmpeg-4.4.tar.gz
tar xf ffmpeg-4.4.tar.gz
cd ffmpeg-4.4/
./configure --enable-shared --disable-x86asm --prefix=/data/service/ffmpeg
make
make install
加载库文件
vim /etc/ld.so.conf
include ld.so.conf.d/*.conf
/data/service/yasm/lib/
/data/service/ffmpeg/lib/
ldconfig
/data/service/ffmpeg/bin/ffmpeg -version
