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.
