subp2pgm [-hvf] [-o output] [-s sid] vobsub

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.
