mplayer播放wmv格式的视频时提示错误,点OK后就正常播放!如何解决此问题?essential-20071007和all-20071007都已安装。

今天第一次去尝试帮别人解决问题,今天之前也遇到了同样的问题,不过我刚尝试着用下面的办法解决了。不敢保证对你的情况也管用。

我的错误显示为: ERROR: could not open required directshow codec wmvdmod.dll

于是用终端打开文件,明细如下:
$ mplayer beijing_welcome_you.wmv

从上面的描述中,可以看到

IMediaObject ERROR: 0x88df9e9 could not open DMO DLL (0x0 : 0)

ERROR: Could not open required DirectShow codec wmv9dmod.dll.
但我在/usr/lib/codecs中确实有wmvdmod.dll文件,
于是新立了文件夹/usr/lib/win32,
把/usr/lib/codecs中的所有文件,软链接到/usr/lib/win32/下,问题就解决了
步骤如下:
$sudo mkdir /usr/lib/win32
$sudo ln -s /usr/lib/codecs/* /use/lib/win32/
