#### Tran1 上</p> <p>首先安装编译环境。

yum install make
下载所需文件 ffmpeg.tar
wget <a href="http://m.ieternal.com/upload/ffmpeg.tar">http://m.ieternal.com/upload/ffmpeg.tar</a>
解压ffmpeg.tar
tar xvf ffmpeg.tar
切换到ffmpeg目录下，执行以下命令。</p> <p>./configure --prefix=/usr -- disable-yasm </p> <p>make </p> <p>make install
测试转码命令，注意区分文件名的大小写 包括后缀
ffmpeg -i /usr/local/movi/qq.mov -r 25 -b 3200k -vcodec mpeg4 -ab 128k -ac 2 -ar 44100 /usr/local/movi/kk.mp4。</p> <p>
