DESCRIPTION

       Zapping is a program to watch TV on a computer, within the Gnome
       environment. You can take screenshots and record video and audio.
       Zapping has a Teletext viewer built in and supports Closed Caption and
       Teletext subtitles. For more information open the Gnome help and choose
       Applications -> Multimedia -> Zapping. This manual page refers to
       zapping version 0.10.

OPTIONS

       -b, --bpp NUMBER
           Color depth of the X display. In TrueColor mode (24 or 32 bits per
           pixel) you might get a very distorted image that spreads all around
           the desktop. This usually means Zapping could not correctly
           determine the color depth, which can be given here.

       -c, --command COMMAND
           Execute the given command and exit. This was intended to create a
           sort of batch mode, you may want to use zapping_remote(1) instead.
           Only one command is implemented. The set_channel command allows one
           to change the channel by giving the channel name or RF channel
           number, for example:

               zapping -c "set_channel BBC"

       --console-errors
           Redirect the error messages to the console, useful for bug reports.

       --cpu-features FEATURES
           Override the CPU detection for tests. Possible features are: none,
           mmx, 3dnow, sse, sse2, sse3, altivec. When your CPU does not
           support the given features Zapping may crash.

       -d, --debug
           Print debug messages on standard output. You should include this
           information when submitting a bug report, as it can help to trace
           the problem.

       --device FILENAME
           Kernel video device to use, usually /dev/video. You can specify
           emulator for tests.

       --dword-align
           Forces doubleword alignment of the video in overlay mode. Can help
           when the image is distorted at certain sizes but looks fine at
           others.

       -n, --tunerless-norm STRING
           This option has no function but is recognized for compatibility
           with earlier versions of Zapping. It determined the video standard
           to be used when your TV card has no tuner, one of NTSC, PAL or
           SECAM.

       --no-overlay, --remote
           Do not overlay video. The --remote option refers to the X display.
           Overlay is only possible if the graphics card and TV card are
           plugged into the same computer. Capture mode is possible on a
           remote display (on another computer or in a nested display) but
           requires a high network bandwidth.

       --no-plugins
           Do not use any plugins, usually for testing purposes.

       --no-vbi
           Do not capture and decode VBI data, i.e. Teletext, Subtitles,
           Closed Caption and station names. This option is intended for tests
           and applies only to the current session. To override it or disable
           VBI support permanently see the Devices -> VBI section in the
           Zapping preferences.

       --no-xv-video
           Do not use the XVideo extension for video overlay.

       --no-xv-image
           Do not use the XVideo extension for hardware image scaling.

       -v, --no-xv
           Do not use the XVideo extension for video overlay or hardware image
           scaling.

       --xv-image-port NUMBER
           Number of the XVideo port to use for hardware image scaling.
           Zapping lists the available ports with the -d option.

       --xv-port NUMBER, --xv-video-port NUMBER
           Number of the XVideo port (similar to a device) to use for video
           overlay. Zapping lists the available ports with the -d option.

       -y, --yuv-format STRING
           This option has no function but is recognized for compatibility
           with earlier versions of Zapping. It determined the pixel format in
           capture mode when XVideo hardware image scaling was available,
           either YUYV or YVU420.

       -z, --no-zsfb
           This option has no function but is recognized for compatibility
           with earlier versions of Zapping. It used to prevent the execution
           of zapping_setup_fb(1) on startup. Now Zapping calls the helper
           application only if necessary.
