FFMpeg安装

 

FFmpeg安装

svn checkout svn://svn.mplayerhq.hu/ffmpeg/trunk ffmpeg

./configure --enable-shared --disable-yasm --prefix=/usr/local/ffmpeg

make && make install

cd /usr/lib

ln -s /usr/local/ffmpeg/lib/* .

 

 

ffmpeg正常安装后执行ffmpeg时出现如下错误：

ffmpeg: error while loading shared libraries: libavdevice.so.52: cannot open shared object file: No such file or directory

解决办法：

vi /etc/ld.so.conf

加入：/usr/local/lib

执行ldconfig

 

获取MP3播放时间命令：

ffmpeg -i test.mp3 2>&1|grep Duration

or

ffprobe -show_format test.mp3|grep duration
