今天对公司线上的几台机器做了下ffmpeg的更新，没有什么技术含量，还是简单记录下，做个流水账~哈哈
官方网站：https://ffmpeg.org/download.html
github：https://github.com/FFmpeg/FFmpeg/releases
升级前确认版本信息 ==> 2.4
[root@thatsit FFmpeg-n3.1.2]# ffmpeg -version|grep version ffmpeg version 2.4 Copyright (c) 2000-2014 the FFmpeg developers [root@thatsit FFmpeg-n3.1.2]#
下面以更新到3.1.2为例
1，安装新版本ffmpeg
wget https://github.com/FFmpeg/FFmpeg/archive/n3.1.2.tar.gz tar xf n3.1.2.tar.gz cd FFmpeg-n3.1.2 ./configure --prefix=/usr/local/ffmpeg_3.1.2/ --enable-gpl --enable-shared --enable-libmp3lame --enable-libvorbis --enable-pthreads --disable-ffserver --enable-nonfree --enable-libx264 --enable-libfdk_aac --enable-decoder=png --enable-encoder=png --enable-libopencv make make install
安装之后的目录结构如下：
[root@BJSH-SLATLAS-02.meitu-inc.com ~]# tree -L 1 /usr/local/ffmpeg_3.1.2/ /usr/local/ffmpeg_3.1.2/ ├── bin ├── include ├── lib └── share 4 directories, 0 files [root@BJSH-SLATLAS-02.meitu-inc.com ~]#
2，调整动态链接库
[root@thatsit ~]# tail -1 /etc/ld.so.conf /usr/local/ffmpeg_3.1.2/lib [root@thatsit ~]#
如果程序找不到动态链接库，会报类似下面的错误信息：
[root@thatsit bin]# ffprobe ffprobe: error while loading shared libraries: libavdevice.so.57: cannot open shared object file: No such file or directory [root@thatsit bin]#
3，删除之前的软链接并重新创建软链接
[root@thatsit FFmpeg-n3.1.2]# which ffmpeg /usr/local/bin/ffmpeg [root@thatsit FFmpeg-n3.1.2]# cd /usr/local/bin/ [root@thatsit bin]# ll|grep ff lrwxrwxrwx 1 root root 28 Oct 22 2015 ffmpeg -> /usr/local/ffmpeg/bin/ffmpeg [root@thatsit bin]# rm -f ffmpeg [root@thatsit bin]# ln -s /usr/local/ffmpeg_3.1.2/bin/ffmpeg . [root@thatsit bin]# ln -s /usr/local/ffmpeg_3.1.2/bin/ffprobe . [root@thatsit bin]# ll|grep ff lrwxrwxrwx 1 root root 34 Mar 1 23:17 ffmpeg -> /usr/local/ffmpeg_3.1.2/bin/ffmpeg lrwxrwxrwx 1 root root 35 Mar 1 23:17 ffprobe -> /usr/local/ffmpeg_3.1.2/bin/ffprobe [root@thatsit bin]#
[root@thatsit ~]# ffmpeg -version|grep version ffmpeg version 3.1.2 Copyright (c) 2000-2016 the FFmpeg developers [root@thatsit ~]#
ps：需要查看ffmpeg的详细信息可以使用ffmpeg -version或者直接使用ffmpeg命令进行查看
ffmpeg -version
