iPad中的OPlayer只支持srt格式的字幕，而動畫一般使用的是ass/ssa格式的字幕，所以需要將ass/ssa批量轉(zhuǎn)換srt。

Google了一下，在《ass2srt[ass/ssa批量轉(zhuǎn)換srt]》中找到一個ass2srt.wsf腳本，內(nèi)容如下：

Windows 腳本 (.wsf) 文件是一個包含可擴展標記語言(XML)代碼的文本文檔，它結(jié)合了若干功能，提高了腳本編程的靈活性。由于 Windows 腳本文件并不局限于特定的引擎，它們能夠包含所有遵循 ActiveX(R)規(guī)范的腳本引擎的腳本。

上面的腳本文件同時包含了JScript和VBScript的代碼。問題在于，有這個必要么？單純用JScript或者VBScript都可以實現(xiàn)，為什么要混用不同的語言呢？JScript在代碼中的作用僅僅是正則表達式而已，一個合理的推斷是作者不會VBScript的正則表達式，或者嫌VBScript的正則表達式太麻煩。就算撇開語言混雜不說，上面代碼的風格實在是不敢恭維。

下面是我寫的ass2srt.vbs，也許比上面的代碼好一點點罷。

把上面代碼保存為ass2srt.vbs，然后將需要轉(zhuǎn)換的ass/ssa字幕拖動到ass2srt.vbs腳本上即可。如果需要批量轉(zhuǎn)換的ass/ssa字幕比較多，可以先把它們放到同一個文件夾里，然后直接雙擊運行ass2srt.vbs，選擇字幕所在的文件夾即可。
