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 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.
