NAME

zapping - a Gnome TV and Teletext viewer

SYNOPSIS

zapping [-b, --bpp NUMBER] [-c, --command STRING] [--console-errors] [--cpu-features FEATURES] [-d, --debug] [--device FILENAME] [--dword-align] [-n, --tunerless-norm STRING] [--no-overlay, --remote] [--no-plugins] [--no-vbi] [--no-xv-image] [--no-xv-video] [-v, --no-xv] [--xv-image-port NUMBER] [--xv-port NUMBER, --xv-video-port NUMBER] [-y, --yuv-format STRING] [-z, --no-zsfb]

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.
