iPad中的OPlayer只支持srt格式的字幕，而動(dòng)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(gè)ass2srt.wsf腳本，內(nèi)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

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

Windows 腳本 (.wsf) 文件是一個(gè)包含可擴(kuò)展標(biāo)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(shí)包含了JScript和VBScript的代碼。問題在于，有這個(gè)必要么？單純用JScript或者VBScript都可以實(shí)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(dá)式而已，一個(gè)合理的推斷是作者不會(huì)VBScript的正則表達(dá)式，或者嫌VBScript的正則表達(dá)式太麻煩。就算撇開語言混雜不說，上面代碼的風(fēng)格實(shí)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(diǎn)點(diǎn)罷。

i = i + 1
arr = Split(str, ",", 10)
s = "0" arr(1) "0" 'Start time
e = "0" arr(2) "0" 'End time
t = arr(9) 'Text
s = Replace(s, ".", ",")
e = Replace(e, ".", ",")
t = re.Replace(t, "")
t = Replace(t, "\n", vbCrLf)
t = Replace(t, "\N", vbCrLf)
srt.WriteText i vbCrLf

End Function
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(dòng)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(gè)文件夾里，然后直接雙擊運(yùn)行ass2srt.vbs，選擇字幕所在的文件夾即可。
