NAME

subp2pgm - convert VobSub DVD subtitles into pgm files and xml description

SYNOPSIS

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

DESCRIPTION

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.
