ogmrip is originally a graphics package to convert dvd into ogm files.
|
||||||
|
This package only takes the subtitle extraction part.
|
||||||
|
Namely:
|
||||||
|
- sub2pgm: converts vobsub files into an srt template and a set of pgm images.
|
||||||
|
- srttool: manipulates srt templates and srt files.
|
||||||
|
|
||||||
|
Together with mplayer, which can extract vobsub, and gocr, to handle character
|
||||||
|
recognition, this allows for simple subtitle extraction.
|
||||||
|
|
||||||
|
The package contains a shell-script, subrip, that puts all the pieces
|
||||||
|
together and can be tailored for further use.
