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批量轉換srt。
Google了一下，在《ass2srt[ass/ssa批量轉換srt]》中找到一個ass2srt.wsf腳本，內容如下：
| <job id="ass2srt"> <script language="JScript"> cInput="unicode"; // You can find them from: cOutput="utf-8"; // HKEY_CLASSES_ROOT/MIME/Database/Charset function rrr(){ re = /Dialogue: [^,.]*[0-9]*,([1-9]?[0-9]*:[0-9]*:[0-9]*.[0-9]*),([1-9]?[0-9]*:[0-9]*:[0-9]*.[0-9]*),[^,.]*,[^,.]*,[0-9]*,[0-9]*,[0-9]*,[^,.]*,(.*)/gi; rv = ss.match(re); t1 = RegExp.$1; t2 = RegExp.$2; t3 = RegExp.$3; rg = //{[^}.]*(//pos/([0-9]*,[0-9]*/))[^}.]*}/gi; t3 = t3.replace(rg,"$1" + "}"); rg =//{[^}.]*}/gi; t3 = t3.replace(rg,""); rg =/(//pos/([0-9]*,[0-9]*/)})/gi; t3 = t3.replace(rg,"{" + "$1"); } </Script> <script language="VBScript"> set ad=CreateObject("adodb.stream") set af=CreateObject("adodb.stream") set ass=CreateObject("adodb.stream") ad.open af.open ass.open ad.Charset=cInput af.Charset=cOutput ass.Charset=cOutput Set objArgs = WScript.Arguments For I = 0 to objArgs.Count - 1 ad.LoadFromFile(objArgs(I)) z=0 gg=left(objArgs(I),len(objArgs(I))-3)&"srt" Do While ad.eos <> True ss =ad.ReadText(-2) if left(ss,8)="Dialogue" then ss=replace(ss,",,",",d,") rrr t3=replace(t3,"/n",vbcrlf) t3=replace(t3,"/N",vbcrlf) z=z+1 af.writetext z,1 af.writetext t1 & " --> " & t2,1 af.writetext t3 & vbcrlf & vbcrlf else ass.writetext ss,1 end if Loop af.savetofile gg,2 ass.savetofile gg&".style",2 Next if i=0 then msgbox "Please drag files to me!",,"Error!" else msgbox "Converted "&i&" file(s).",,"All Over!" end if </Script></job> |
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，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。
