• 更新ffmpeg


    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

    软件包获取方式

    官方网站:https://ffmpeg.org/download.html
    github:https://github.com/FFmpeg/FFmpeg/releases

    更新前版本确认

    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]#

    更新操作

    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]#
    

    版本验证

    [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

    [root@thatsit bin]# ffmpeg -version

    Use -h to get full help or, even better, run 'man ffmpeg'
