       dv2sub -	extract	info or	subtitles from DV stream

       dv2sub {-i | -s}	[dv-file]

       dv2sub --subtitles-out sub-file [dv-file]

       Utility dv2sub reads raw	DV stream from file argument dv-file or
       standard	input if absent. It can	generate a parametr log	about every
       input DV	frame or create	MicroDVD subtitles with	the recording date &

       Memory mapped I/O is used for seekable input when available. It is
       faster than sequential access.

       dv2sub uses GPL codec for DV video LibDV, see

       -i, --info
	  Generate a simple information	about every input DV frame. Reported
	  are: frame number (counting from 0), video norm PAL/NTSC, aspect
	  ratio	normal (4:3) or	wide (16:9), interlaced	or progressive
	  material, number of audio channels, audio sampling frequency,	number
	  of audio samples, timestamp, recording date &	time.

	  Dump SSYB packets in hexadecimal form. (implies -i)

	  Dump VAUX packets in hexadecimal form. (implies -i)

       --info-out info-file
	  Generate info	(like with option -i, --info) and write	output into
	  file info-file.

       -s, --subtitles
	  Generate MicroDVD subtitles with the recording date &	time.

       --subtitles-out sub-file
	  Generate subtitles (like -s, --subtitles) and	write output into file

       -f, --time-format fmt
	  Use the format specification fmt by strftime() to output a subtitle
	  line.	The default format value is `%F|%T'.

       -b, --boundary time
	  Don't	output subtitles with time above a boundary. The option
	  argument syntax is YYYY[-mm[-dd [HH:MM[:SS]]]]. Default values for
	  missing parts	are the	minimal	ones. E.g.  2007 sets boundary to
	  2007-01-01 00:00:00.

	  Suppose you recorded a video.	You grabbed video into a computer and
	  edit it with non-linear editor like kino latter. Video transitions
	  between scenes have date and time set	to time	of editing. You	can
	  use this option to filter out	date and time subtitles	of edited

       -n, --max-frames	num
	  Don't	process	more than num frames.

       -d, --date1
	  Output one line with the recording date & time from the 3rd frame.

	  Don't	use mmap().

       -p, --pass-through
	  Pass an input	DV stream to stdout (implies --no-mmap). This option
	  is usable mainly if you need to extract subtitles and	encode the DV
	  in one pass. You can avoid reading huge DV file twice	by passing
	  stdout through pipe to an encoder (ffmpeg, mpeg2enc,...).

       -h, --help
	  Output a brief help message.

       -V, --version
	  Output a version number.
