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 NUMBERColor 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:
--console-errors
zapping -c "set_channel BBC"
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.
