Dvgrab

dvgrab is a program that captures DV video and audio data from digital

      camcorders  via  an  IEEE1394  link.  (IEEE1394 is also known under the
      various trademarks FireWire, i.Link, or Lynx.) The DV data is stored in
      one  or several files and can later be processed by video editing soft-
      ware.  dvgrab can remote control the camcorder but it does not show the
      video's content on screen.

      The base argument is used to construct the filename to store video data
      in, like base-id.ext where id is a running number starting from 001 and
      ext  is  the  file name extension specifying the file format used, e.g.
      avi.  A different naming scheme is used  whenever  the  --timestamp  is
      given  (see below).  If base is '-' then the format is forced to raw DV
      and sent to stdout. dvgrab will also output raw DV to stdout while cap-
      turing  to a file if stdout is piped or redirected. The default base is
      dvgrab- if not specified.

      You can use dvgrab's powerful file writing capabilities with other pro-
      grams  that produce raw DV. If dvgrab detects that it is on the receiv-
      ing end of a pipe and it is not in interactive mode, then it  will  try
      to read raw DV on stdin.
