xawtv-remote(1) 		     General Commands Manual			  xawtv-remote(1)

       xawtv-remote, v4lctl -- control video4linux devices

       xawtv-remote [ options ] command
       v4lctl [ options ] command

       xawtv-remote and v4lctl can be used to control a video4linux driven TV card.  xawtv-remote
       passes the command to a already running xawtv  or  motv	instance  using  X11  properties.
       v4lctl sets the parameters directly.

       xawtv-remote knows the following options:

       -h     print a short help text

       -d dpy Set the X11 display

       -i id  Set the Window ID.

       v4lctl understands these options:

       -h     print a short help text

       -c device
	      Set video4linux device.

       -v n   Set debug level to n, where n = [0..2]

       Both  tools  basically  use  the same set of commands.  Some of them are useful for xawtv-
       remote only (fullscreen for example).

       setstation [ <name> | <nr> | next | prev | back ]
	      Set the TV station.  This selects on of the TV stations which are configured in the
	      .xawtv  config  file.   The argument can be the station name or a number (the first
	      one listed in the config file is 0, ...).  next/prev  jumps  to  the  next/previous
	      station in the list, back to the previously selected one.

       setchannel [ <name> | next | prev ]
	      Tune in some channel.

       setfreqtab <table>
	      Set the frequency table.	See the menu in xawtv for a list of valid choices.

       setnorm <norm>
	      Set the TV norm (NTSC/PAL/SECAM).

       setinput [ <input> | next ]
	      Set the video input (Television/Composite1/...)

       capture [ on | off | overlay | grabdisplay ]
	      Set capture mode.

       volume mute on | off
	      mute / unmute audio.

       volume <arg>

       color <arg>

       hue <arg>

       bright <arg>

       contrast <arg>
	      Set  the	parameter  to  the specified value.  <arg> can be one of the following: A
	      percent value ("70%" for example).  Some absolute value ("32768"), the valid  range
	      is  hardware specific.  Relative values can be specified too by prefixing with "+="
	      or "-=" ("+=10%" or "-=2000").  The keywords "inc" and "dec" are	accepted  to  and
	      will increase and decrease the given value in small steps.

       setattr <name> <value>
	      Set set the value of some attribute (color, contrast, ... can be set this way too).

       show [ <name> ]
	      Show the value current of some attribute.

       list   List all available attributes with all properties (default value, range, ...)

       snap [ jpeg | ppm ] [ full | win | widthxheight ] <filename>
	      Capture one image.

       webcam <filename>
	      Capture  one  image.  Does basically the same as "snap jpeg win <filename>".  Works
	      also while avi recording is active.  It writes to a temporary file and  renames  it
	      when done, so there is never a invalid file.

       movie driver [ files | raw | avi | qt ]

       movie  video [ ppm | pgm | jpeg | rgb | gray | 422 | 422p | rgb15 | rgb24 | mjpeg | jpeg |
       raw | mjpa | png ]

       movie fps <frames per second>

       movie audio [ mono8 | mono16 | stereo ]

       movie rate <sample rate>

       movie fvideo <filename>

       movie faudio <filename>

       movie start

       movie stop
	      control xawtv's movie recorder.

	      Toggle fullscreen mode.

	      Display time (same what the 'D' key does in xawtv).

       msg text
	      Display text on the  on-screen  display  (window	title  /  upper  left  corner  in
	      fullscreen mode).

       vtx line1 line2 [ ... ]
	      Display  subtitles.   It pops up a small window at the bottom of the screen.  It is
	      supported to be used as interface for displaying subtitles (often on videotext page
	      150 in europe, thats why the name) by external programs.
	      Every  command  line  argument is one line, zero lines removes the window.  You can
	      colorize the text with the control sequence  "ESC  foreground  background".   fore-
	      ground/background  has  the  range  0-7 (ansi term colors).  Example: "\03347 hello
	      world " is blue on white.  "\033" must be  a  real  escape  character,  the  string
	      does'nt  work.   With the bash you'll get it with ^V ESC.  vtx does also understand
	      the ANSI tty escape sequences for color.

       quit   quit xawtv

       keypad n
	      enter digit 'n'.	That's the  two-digit  channel	selection,  entering  two  digits
	      within 5 seconds switches to the selected station.  Useful for lirc.

       vdr command
	      send "command" to vdr (via connect on localhost:2001).

       xawtv(1), motv(1), xawtvrc(5)
