MPlayer无法播放RMVB

试用MPlayer播放RMVB时命令行窗口出现错误提示:

Read the RealVideo section of the DOCS!

并且只能播放声音,无视频图像.
仔细观看错误提示中有这么一句:
ERROR: Could not open required DirectShow codec drv43260.dll.
这应该是real的解码文件.但是我已经将这个DLL文件COPY到了codecs文件中了
之后上网查类似问题.发现和

这个人遇到的问题差不多,不同的是他少的文件为drv42360.dll
他的解决方法是重新注册这个DLL文件.
根据他的方法,我:
1.把drv43260.dll拷贝到系统的system32文件夹下
2.开始->运行->regsvr32 drv43260.dll
之后再次用MPlayer播放RMVB文件.成功!
