       dvgrab -- Grab DV video and audio data via IEEE1394 links

       dvgrab  [--autosplit]   [--card	num]   [--channel  num]   [--format  fmt]  [--frames num]
       [--help]  [--testmode]  [--timestamp]  [--version]  [base]

       This manual page was written for the Debian GNU/Linux distribution  because  the  original
       program	does  not  have  a  manual  page.   Instead,  documentation is provided online at

       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	software.  dvgrab will NOT remote control the camcorder nor show the video's con-
       tent 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 exten-
       sion specifying the file format used, e.g. avi.	A different naming scheme is  used  when-
       ever the --timestamp is given (see below).

		 Try  to  detect  whenever  a  new recording starts, and store it into a separate
		 file. If used together with the --frames option, a  new  file	will  be  started
		 whenever the given frame count is reached.

		 Autosplit is off by default.

       --card num
		 Tells	dvgrab	to  receive data from IEEE1394 card num. Defaults to 0, i. e. the
		 first card found.

       --channel num
		 Isochannel to receive data from. Defaults to 63, which is pretty  much  standard
		 among DV camcorders these days.

       --format dv1 | dv2 | raw | test
		 Specifies the format of the output file(s).  dv1 and dv2 both are AVI files with
		 slightly different DV codecs.	While dv1 produces smaller output, some  applica-
		 tions won't grok it and require dv2 instead.

		 raw  stores the data unmodified. Some old Linux software can handle this format.
		 Furthermore, you can trick the Windows QuickTime app into playing such files  by
		 renaming them to file extension .dv.

		 test  as  the name suggests is used for testing purposes only. The output can be
		 fed back into dvgrab using the --testmode option.

		 Defaults to dv1

       --frames num
		 This option tells dvgrab to store at most num frames per file.  The  correspond-
		 ing  time  depends on the video system used.  PAL shows 25, NTSC about 30 frames
		 per second.

		 Defaults to no frame limit. AVI output, however, has an implicit limit  on  file
		 size, causing AVI file to be split unconditionally when the grow near 1GB.

       --help	 Show summary of options.

		 Read complete video transmission from a file. Used for development only.

		 Put information on date and time of recording into file name.

       --version Show version of program.

       dvgrab foo
		 Captures  video  data	from  the  default IEEE1394 source and stores it to files
		 foo_001.avi, foo_002.avi, etc.

       dvgrab --frames 25 foo
		 Assuming a PAL video source, this command records one second's  worth	of  video

       dvgrab --autosplit --frames 750 --timestamp foo
		 Records  video  data from the default IEEE1394 source, cuts it into chunks of 30
		 seconds (assuming PAL) and names the resulting files according to date and  time
		 info in the videostream.
