This is dv2sub, a simple util that extracts the date and time of recording from
a dv video file (using libdv) and outputs it as a subtitle file.

It can also display useful information about the dv stream, like 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 and recording date & time.

Be sure the input file or stream is in pure RAW DV format. dv2sub doesn't work
with DV AVI files (type 1 or type 2)
