centos 安装ffmpeg

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

tar -zxvf ffmpeg-3.1.tar.gz

cd ffmpeg-3.1

./configure
make
make install

 

接着就是漫长的等待了。。。。。。。。可以去喝杯咖啡了o(∩_∩)o 

 

查看一下版本

ffmpeg -version

 

 

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

 

还有的是,ffmpeg主要是用于解码的。如果需要重新编码,就需要安装新的第三方编码支持。

 重新编译ffmpeg

    1.进入ffmpeg目录,./configure --prefix=/usr/local/ --enable-gpl --enable-version3 --enable-nonfree --enable-shared --enable-zlib --enable-bzlib --enable-libmp3lame --enable-libx264 --enable-pic --enable-libfaac

,然后就生成了新的makefile了。

    2.执行sudo make clean && make sudo make install。

    3.这样ffmpeg就被重新编译了,完了就可以验证一下,使用ffmpeg工具,把某个视频文件中的视频流转码成h264格式,音频流转码成mp3lame格式,不妨试试。

 

转MP3错误情况:

“ffmpeg: error while loading shared libraries: libmp3lame.so.0: cannot open shared object file: No such file or directory”等类似的错误

解决办法是建立软链接:
# ln -s /usr/local/lib/libmp3lame.so.0.0.0 /usr/lib64/libmp3lame.so.0

或者直接修改修改/etc/ld.so.conf

vi  /etc/ld.so.conf

新增一行 

/usr/local/lib
