他有說明3.22 其實只是3.11a 的核心...對於播放根本沒差
DivX ;-) 3.22

This is nothing but a rather lame hack of 3.11 alpha to enable VKI (variable keyframe interval) encoding at all bitrates. However, the built-in scene detection algorithm is terrible and you are better of using programs like Nandub to get real VKI encoding. It has no effect on playback so don't bother with it. You can download it at Doom9 if you really must.

如果你真的很想要的話 可以去doom9.net 找link
