ffmpeg下载地址：http://ffmpeg.org/releases/

1.首先需要安装解码器集合（包含安装ffmpeg用到的所有解码器）下载地址：

链接:https://pan.baidu.com/s/1gxtRLmx20jhvBDHn3qBffA提取码: pwja

因为我的项目中使用x264的解码方式，所有我只安装该解码器。

代码地址：https://www.cnblogs.com/lemon2019/p/14106794.html

tar -xvf x264-master.tar.bz2
cd /usr/local/src/ffmpeg/x264-master/
./configure --prefix=/usr --enable-shared

make

make install

2.ffmpeg安装

tar -vxf ffmpeg-4.3.tar.bz2
./configure --prefix=/usr/local/ffmpeg2 --enable-libx264 --enable-gpl
make
make install
安装完成后执行:
/usr/local/ffmpeg2/bin/./ffmpeg 时出现

error while loading shared libraries: libavdevice.so.53: cannot open shared object file: No such file or director

错误，是因为共享库文件安装到了/usr/local/ffmpeg2/lib目录下, 那么把新共享库目录加入到共享库配置文件/etc/ld.so.conf中, 如下:

# cat /etc/ld.so.conf

include ld.so.conf.d/*.conf

# echo "/usr/local/ffmpeg2/lib" >> /etc/ld.so.conf

# ldconfig

再次执行   /usr/local/ffmpeg2/bin/./ffmpeg

如果出现如下版本信息则安装成功：

3.验证视频格式转码：
