在 terminal 下用 subtitle2vobsub 生出 .idx 與 .sub

必須的程式:mplayersubtitlerippertranscode

首先先抓出該 DVD 內有幾個字幕軌道:

mplayer -dvd-device $RIPDIR dvd://$TITLE -vo null -ao null -frames 0 -v

$TITLE 是該影片位在 DVD 的哪個 Title 中。

輸出結果應該如下:

......
DVD successfully opened.
audio stream: 0 format: ac3 (5.1) language: en aid: 128.
audio stream: 1 format: ac3 (stereo) language: en aid: 132.
number of audio channels on disk: 2.
subtitle ( sid ): 0 language: en
subtitle ( sid ): 1 language: es
subtitle ( sid ): 2 language: pt
subtitle ( sid ): 3 language: ko
subtitle ( sid ): 4 language: zh
subtitle ( sid ): 5 language: th
subtitle ( sid ): 6 language: es
subtitle ( sid ): 7 language: pt
subtitle ( sid ): 8 language: ko
number of subtitles on disk: 9
......

再接下來抓出字幕:

tccat -i $RIPDIR -T $TITLE -L | tcextract -x ps1 -t vob -a 0x24 > subs-zh

註:0x24 為 0x20 + 4 (language:zh 的 index)

再接下來轉成 idx+sub:

subtitle2vobsub -o vobsubs-zh -i $RIPDIR/VIDEO_TS/VTS_01_0.IFO < subs-zh

就會生出 vobsubs-zh.idx 與 vobsubs-zh.sub 了。
