v4lctl1x

Part of xawtv-remote(1x).

Usage

xawtv-remote [options] command

v4lctl [options] command

Overview

xawtv-remote and v4lctl can be used to control a video4linux driven TV card. xawtv-remote passes the command to a already running xawtv instance using X11 properties. v4lctl sets the parameters directly.

Options

xawtv-remote knows the following options:

-h

print a short help text

-d dpy

Set the X11 display

-i id

Set the Window ID.

v4lctl understands these options:

-h

print a short help text

-c device

Set video4linux device.

-v n

Set debug level to n, where n = [0..2]

Commands

Both tools basically use the same set of commands. Some of them are useful for xawtv-remote only (fullscreen for example).

setstation [ <name> | <nr> | next | prev | back ]

Set the TV station. This selects on of the TV stations which are configured in the .xawtv config file. The argument can be the station name or a number (the first one listed in the config file is 0, ...). next/prev jumps to the next/previous station in the list, back to the previously selected one.

setchannel [ <name> | next | prev ]

Tune in some channel.

setfreqtab <table>

Set the frequency table. See the menu in xawtv for a list of valid choices.

setnorm <norm>

Set the TV norm (NTSC/PAL/SECAM).

setinput [ <input> | next ]

Set the video input (Television/Composite1/...)

capture [ on | off | overlay | grabdisplay ]

Set capture mode.

volume <n>
color <n>
hue <n>
bright <n>
contrast <n>

Set the parameter to the specified value. Range for all values is 0 <= n <= 65535. <n> can be either absolute (like "32768") or relative (marked by a sign, like "+1000" or "-512"). "inc" and "dec" are accepted too and increase/decrease the parameter by one percent. "volume" additionally accepts "mute".

snap [ jpeg | ppm ] [ full | win | widthxheight ] <filename>

Capture one image.

fullscreen
