DV2SUB(1) DV2SUB(1) NAME dv2sub - extract info or subtitles from DV stream SYNOPSIS dv2sub {-i | -s} [dv-file] dv2sub --subtitles-out sub-file [dv-file] DESCRIPTION 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 & time. 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 http://libdv.sourceforge.net/. OPTIONS -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 au- dio channels, audio sampling frequency, number of audio samples, time- stamp, recording date & time. --ssyb-dump Dump SSYB packets in hexadecimal form. (implies -i) --vaux-dump 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 sub-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 op- tion to filter out date and time subtitles of edited parts. -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. --no-mmap 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.
