    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).
    -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(1).
    Resource: xawtv.bpp (int).
    -shift n
    Shift the video display by n bytes. Try this if your video display is'nt within the xawtv window, some older matrox cards show this problem. This gets passed through to v4l-conf(1) too.
    Resource: xawtv.shift (int).
    -fb
    Use the framebuffer device to determine the video framebuffer address (instead of the DGA extention). Yet another pass through argument.
    Resource: xawtv.fbdev (bool).
    -xv/-noxv
    enable/disable the usage of the Xvideo extention (for overlay), default is on.
    Resource: xawtv.xvideo (bool).
    -scale/-noscale
    enable/disable the usage of the Xvideo extention (for hardware scaling in grabdisplay mode), default is on.
    Resource: xawtv.hwscale (bool).
    -vm/-novm
    enable/disable the usage of the VidMode extention, default is off. If there is a fullscreen video mode configured in the config file, the vidmode extention will be enabled automatically.
    Resource: xawtv.vidmode (bool).
    -dga/-nodga
    enable/disable the usage of the DGA extention, 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 Extention for video devices. Note that the Xvideo extention does support overlay only, you can't capture images/movies if the Xvideo extention 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 alot 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.
