推荐答案

文档 [ ^ ]说明一切：

Documentation[^] says it all:

根据注册表，AVIFileOpen中指定的文件类型没有处理它的处理程序。

According to the registry, the type of file specified in AVIFileOpen does not have a handler to process it.

粗略地说：你的系统无法为你提供一个能够播放那种类型文件的界面。

Roughly: your system cannot provide you an interface able to play files of that type.
