理論上像mkv、mp4這種文件是不需要預先index的,直接從頭部就可以讀取entry point,像DSS2讀取mkv或者LSMASHVideoSource讀取mp4那樣。ffms2能力有限不管啥東西都要index一遍是它自己的問題(DGNV讀mkv/mp4也是一樣)。就算是多個文件合併,只要知道每個文件的entry point list,跳到後面的文件只需要將需要的幀號計算出來就行了,同樣不會產生index的需要。

I, personally, for me, believe (obviously sometimes) that my OS choice is right. That's me. I'm not telling you that you should believe it. Learn the facts, and the origins behind the facts, and make up your own damn mind. That's why you have one. (source)
