[root@MADING mplayer-checkout-2011-09-05]# ./configure
No FFmpeg checkout, press enter to download one with git or CTRL+C to abort
./configure:行53: git: 未找到命令
Failed to get a FFmpeg checkout
于是我下了ffmpeg并安装拉
但是
[root@MADING mplayer-checkout-2011-09-05]# ./configure
You have an outdated FFmpeg SVN checkout in ffmpeg/, please (re)move or replace it
怎么办
