mplayer播放rm或rmvb视频报错

mplayer video.rm

报错：
Opening video decoder: [realvid] RealVideo decoder
Win32 LoadLibrary failed to load: drvc.dll, /usr/lib/codecs/drvc.dll, /usr/lib/win32/drvc.dll, /usr/local/lib/win32/drvc.dll

解决：

下载realpayer中的drvc.dll

下载地址，http://download.youkuaiyun.com/detail/newman0708/5148863

cp drvc.dll /usr/lib/codecs/ -i

如果还不行，再用以下方法
$ find /usr/lib -name drvc*
/usr/lib/codecs/drvc.so

$ ldd /usr/lib/codecs/drvc.so
    linux-gate.so.1 =>  (0xb774b000)
