NAME

       xawtv - a X11 program for watching TV

SYNOPSIS

       xawtv [ options ] [ station name ]

DESCRIPTION

       xawtv is a X11 application for watching TV with your unix box. It uses the Athena widgets.

OPTIONS

       All  command  line  options also have a Resource, so you can put them into your .Xdefaults
       file too.

       -h, -help
              Print a short description of all command line options.

       -hwscan
              Print a list of available devices.

       -f, -fullscreen
              startup in fullscreen mode.
              Resource: xawtv.fullscreen (bool).

       -n, -noconf
              don't read the config file ($HOME/.xawtv).
              Resource: xawtv.readconfig (bool).

       -o, -outfile base
              set basestring for  the  snapshot  output  files.   The  filename  will  be  "base-
              timestamp-nr.ext".
              Resource: xawtv.basename (string).

       -c, -device device
              set  video4linux device (default is /dev/video0).  This option also disables Xvideo
              support.
              Resource: xawtv.device (string).

       -D, -driver name
              set video4linux driver (default is "libv4l").  This  option  also  disables  Xvideo
              support.
              Resource: xawtv.driver (string).

       -C, -dspdev device
              set audio device (default is /dev/dsp).
              Resource: xawtv.dspdev (string).

       -vbidev device
              set vbi device (default is /dev/vbi0).
              Resource: xawtv.vbidev (string).

       -c, -xvport number
              set Xvideo port (defaults to the first usable if Xvideo is available).  This option
              also enables Xvideo support.
              Resource: xawtv.xvport (int).

       -joydev device
              joystick device to use for controlling xawtv.
              Resource: xawtv.joydev (string).

       -v, -debug level
              Be verbose, level may be 0 (default), 1 or 2.  It exists  just  for  debugging  and
              trouble-shooting.
              Resource: xawtv.debug (int).

       -remote
              X11  display  is remote.  This basically disables overlay mode, you might need this
              if xawtv fails to autodetect a remote X11 display.
              Resource: xawtv.remote (bool).

       -b, -bpp n
              force xawtv into n bpp color depth.  Works for switching between  15/16  and  24/32
              bpp.  This gets just passed through to v4l-conf(8).
              Resource: xawtv.bpp (int).

       -shift n
              Shift  the  video  display by n bytes.  Try this if your video display isn't within
              the xawtv window, some older matrox cards show  this  problem.   This  gets  passed
              through to v4l-conf(8) too.
              Resource: xawtv.shift (int).

       -fb    Use  the  framebuffer device to determine the video framebuffer address (instead of
              the DGA extension).  Yet another pass through argument.
              Resource: xawtv.fbdev (bool).

       -xv/-noxv
              enable/disable the usage of the Xvideo extension altogether,  i.e.  -noxv  has  the
              same effect as both -noxv-video and -noxv-image switches (see below).
              Resource: xawtv.xv (bool).

       -xv-video/-noxv-video
              enable/disable   the  usage  of  the  Xvideo  extension  for  video  overlay  (i.e.
              XvPutVideo).  overlay mode uses this.  default is on.
              Resource: xawtv.xvVideo (bool).

       -xv-image/-noxv-image
              enable/disable  the  usage  of  the  Xvideo  extension  for  image  scaling   (i.e.
              XvPutImage).  grabdisplay mode uses this.  default is on.
              Resource: xawtv.xvImage (bool).

       -vm/-novm
              enable/disable  the  usage of the VidMode extension, default is off.  If there is a
              fullscreen video mode configured in the config file, the vidmode extension will  be
              enabled automatically.
              Resource: xawtv.vidmode (bool).

       -dga/-nodga
              enable/disable the usage of the DGA extension, default is on.
              Resource: xawtv.dga (bool).

       -parallel n
              use n compression threads (default: one).
              Resource: xawtv.parallel (int).

       The usual toolkit options like -geometry are supported too.

SUPPORTED HARDWARE / INTERFACES

       v4l2   video4linux two - modern standard linux video capture API

       libv4l work  through the libv4l library, which provides an additional thin layer on top of
              video4linux2 devices for support of more  wide  range  of  devices'  pixel  formats
              (often required for webcams etc.)  It is default for Xawtv on Linux systems.

       bktr   FreeBSD / OpenBSD driver for bt848/878 grabber cards.

       Xvideo X11  Extension  for  video  devices.   Note  that the Xvideo extension does support
              overlay only, you can't capture images/movies if the Xvideo extension is used.   On
              the  other  hand  this  is  the  only  way to scaled video overlay (i.e. fullscreen
              without black borders @ 1024x748) if both hardware and xfree86 driver  support  it.
              See README.xfree4 for more details and hints on how to setup Xvideo.

GETTING STARTED

       Just  start  xawtv.  Then verify the settings in the options menu (right mouse button) and
       adjust the settings (TV norm, Video source, frequency table).  With the  cursor  keys  you
       can control the tuner and look for TV Stations.  Other useful hotkeys are listed below.

       The  hotkey  'E'  will  show  the channel editor where you can create/edit entries your TV
       stations.  Don't forget to click  on  "save"  to  write  a  config  file.   You  can  also
       create/edit  a  config  file with any text editor, see xawtvrc(5) for a description of the
       config file syntax.  There are a number of config options which can only be set by editing
       the config file.

       You  can  also  check out scantv.  That's a command line tool which will perform a channel
       scan and write out a xawtv config file with all channels it has found.

   Mouse functions
       The left mouse button will popup a menu with all TV stations found in the config file. The
       middle button switches to the next station. The right button brings up a window with a lot
       of options and control functions.

BUGS

       Bug reports with images attached go to /dev/null unseen.

       xawtv depends on a correct driver configuration.  If you can't tune TV  stations  even  if
       the settings in the options window are correct it is very likely a driver issue.

       The  mono/stereo  display  is  not  reliable due to v4l API restrictions.  The API can not
       report back the current audio mode, but a list of the currently  available  modes.   xawtv
       just  does  a  guess  based  on  that,  assuming  the driver uses the best available mode.
       Depending on your hardware this might not be true. If  in  doubt  whenever  stereo  really
       works, please tune in MTV and listen, don't trust what xawtv says.
