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