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.
