tvtime-configure - change settings in the tvtime configuration file
SYNOPSIS
tvtime-configure [ OPTION ] ...
DESCRIPTION
tvtime-configure allows a user to set configuration settings for tvtime without starting the application. This is useful for installation
programs such as debconf to let them configure tvtime without having to write a parser for the configuration file. The command line
options are a subset of those for tvtime itself.
OPTIONS -a, --widescreen
This option starts tvtime in 16:9 aspect ratio mode.
-A, --nowidescreen
This option starts tvtime in 4:3 aspect ratio mode.
-h, --help
Show usage information.
-m, --fullscreen
Start tvtime in fullscreen mode.
-M, --window
Start tvtime in windowed mode.
-p, --fspos=POS
Set the fullscreen window position. Use this if you have a projector to help tvtime fit properly onto your screen.
o top
o bottom
o centre (default)
-F, --configfile=FILE
Additional config file to load settings from.
-H, --height=HEIGHT
Sets the height of the output window to start up at in scanlines. The default output window size is 576 scanlines.
-I, --inputwidth=SAMPLING
V4L input scanline sampling (defaults to 720. This sets how many pixels per scanline to request from the capture card. A higher
setting gives better quality, while a lower setting means we do less work, and so tvtime will run faster. If you have a slower CPU
(like, less than 500Mhz or so), maybe values of 480 or 400 might suit you best. For best quality, choose a high value like
720 or 768. Many capture cards cannot sample higher than 768 pixels per scanline.
-d, --device=NAME
video4linux device to use (defaults to /dev/video0).
-b, --vbidevice=DEVICE
VBI device to use (defaults to /dev/vbi0).
-i, --input=INPUTNUM
video4linux input number (defaults to 0). Cards commonly have a bunch of sources, for example, on my WinTV card, source 0 is my
tuner and source 1 is the composite input.
-c, --channel=CHANNEL
On startup, tvtime will tune to the given channel. Otherwise, the channels from the config file will be used.
-n, --norm=NORM
The mode to set the tuner to (defaults to NTSC). Valid modes are:
o NTSC
o PAL
o SECAM
o PAL-NC
o PAL-M
o PAL-N
o NTSC-JP
-f, --frequencies=NAME
The channels you are receiving with the tuner (defaults to us-cable). Valid values are:
o us-cable
o us-broadcast
o japan-cable
o japan-broadcast
o europe
o australia
o australia-optus
o newzealand
o france
o russia
-R, --priority=PRI
Sets the process priority (see nice(1)) that tvtime should be run at.
-t, --xmltv=FILE
Reads XMLTV listings from the given file to display on the OSD. Channels are looked up based on their name, and tvtime will display
the show title, sub-title and show description on the OSD.
-l, --xmltvlanguage=LANG
Use XMLTV data in given language, if available. Languages are represented by their two-letter language code (for example, "de" for
German). The default language used in the file will be used if this is unset or set to "none"
-x, --mixer=DEVICE[:CH]
The mixer device and channel for the volume controls. (defaults to /dev/mixer:line). Valid channels are:
o vol
o bass
o treble
o synth
