Overview
subp2pgm converts DVD subtitles from the VobSub format into an intermediate form suitable for OCR extraction.
subp2pgm takes two files as input, which should be named <vobsub>.idx and <vobsub>.sub, where vobsub is the basename of the files.
subp2pgm outputs one .pgm graphics file for each subtitle image, and a .xml description file with correct timing annotation, where each subtitle entry is replaced by the corresponding graphics file.
After OCR conversion, such a file can be transformed into a proper srt file by subptools(1). The options are as follows:
-
-h, --help -
Display usage and quit.
-
-v, --verbose -
Increase verbosity level.
-
-f, --forced -
Extract forced subtitles only.
-
-n, --normalize -
Normalize the palette.
-
-o, --output output -
Basename for all pgm output files and the xml description.
-
-s, --sid sid -
Selects subtitle id from a vobsub file with several subtitle streams. Defaults to 0.
