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 file too.
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
Resource: xawtv.basename (string).
-c, -device device
set video4linux device (default is /dev/video0). This option
also disables Xvideo support.
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 trouble-shooting.
Resource: xawtv.debug (int).
X11 display is remote. This basically disables overlay mode,
you might need this if xawtv fails to autodetect a remote X11
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-
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
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
Resource: xawtv.xvVideo (bool).
enable/disable the usage of the Xvideo extension for image
scaling (i.e. XvPutImage). grabdisplay mode uses this. default
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 enabled
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 design bugs.
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
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.
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
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)
Ctrl+J Grab picture (window size, jpeg)
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.
