mplayer 播放mms的问题

[Qingsu Chen <alickcqs@gmail.com>]

偶要看世界杯。学校有cctv的mms网页。但是我用mplayer来播放却出现如下错误：
$ mplayer mms://172.17.4.1/cctv5

Couldn't resolve name for AF_INET6: 172.17.4.1
read error:: Operation now in progress
pre-header read failed
Couldn't resolve name for AF_INET6: 172.17.4.1
Server returned 404:Not Found
Failed to parse header.
Failed, exiting.

这个是什么问题？
