xawtv - a X11 program for watching TV
xawtv [ options ] [ station name ]
xawtv is a X11 application for watching TV with your unix box. It uses the Athena widgets.
All command line options also have a Resource, so you can put them into your .Xdefaults
Print a short description of all command line options.
Print a list of available devices.
startup in fullscreen mode.
Resource: xawtv.fullscreen (bool).
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-time-
Resource: xawtv.basename (string).
-c, -device device
set video4linux device (default is /dev/video0). This option also disables Xvideo
Resource: xawtv.device (string).
-C, -dspdev device
set audio device (default is /dev/dsp).
Resource: xawtv.dspdev (string).
set vbi device (default is /dev/vbi).
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).
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
Resource: xawtv.debug (int).
X11 display is remote. This basically disables overlay mode, you might need this
if xawtv failes 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 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).
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).
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).
enable/disable the usage of the Xvideo extension for image scaling (i.e. XvPutIm-
age). grabdisplay mode uses this. default is on.
Resource: xawtv.xvImage (bool).
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
Resource: xawtv.vidmode (bool).
enable/disable the usage of the DGA extension, default is on.
Resource: xawtv.dga (bool).
use n compression threads (default: one).
Resource: xawtv.parallel (int).
The usual toolkit options like -geometry are supported too.
SUPPORTED HARDWARE / INTERFACES
v4l video4linux - the linux video capture API.
v4l2 video4linux two - new, improved capture interface which fixes a number of v4l
bktr FreeBSD / OpenBSD driver for bt848/878 grabber cards.
Xvideo X11 Extension for video devices. Note that the Xvideo extension does support over-
lay 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.
Just start xawtv. Then verify the settings in the options menu (right mouse button) and
adjust the settings (TV norm, Video source, freqency 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 sta-
tions. 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
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.
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.
V Video (Capture) on/off
A Audio on/off
F Fullscreen on/off
G Grab picture (full size, ppm)
J Grab picture (full size, jpeg)
Ctrl+G Grab picture (window size, ppm)

O Popup Options Window
C Popup Channels Window
E Popup Channel Editor
R Popup AVI Recording Window
Z Channel Hopper (zapping, tune in every
station a few seconds)
Ctrl+Z Fast Channel Hopping (grab the images for the
up/down tune up/down one channel
left/right fine tuning
pgup/pgdown station up/down (the ones you have in the config file)
space next station (same as pgup)
backspace previously tuned station
Ctrl+up scan for next station
F5-F12 adjust bright/hue/contrast/color
+/- Volume up/down (keypad)
Enter mute (keypad)
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.
