v4lctl(1)


NAME

   xawtv-remote, v4lctl -- control video4linux devices

SYNOPSIS

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

DESCRIPTION

   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.

OPTIONS

   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.

   -D driver
          Set video4linux driver.

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

COMMANDS

   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.

   fullscreen
          Toggle fullscreen mode.

   showtime
          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 intended to  be  used  as  an  interface  for
          displaying  subtitles  (often  on  videotext page 150 in Europe,
          that's 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".   foreground/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  doesn't  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).
