- Set the Window ID. v4lctl understands these options:
- -h
- print a short help text

- -D driver
- Set video4linux driver.
- -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 mute on | off
- mute / unmute audio.
- volume <arg>
- color <arg>
- hue <arg>
- bright <arg>
- contrast <arg>
- Set the parameter to the specified value. <arg> can be one of the following: A percent value ("70%" for example). Some absolute value ("32768"), the valid range is hardware specific. Relative values can be specified too by prefixing with "+=" or "-=" ("+=10%" or "-=2000"). The keywords "inc" and "dec" are accepted to and will increase and decrease the given value in small steps.
- setattr <name> <value>
- Set set the value of some attribute (color, contrast, ... can be set this way too).
- show [ <name> ]
- Show the value current of some attribute.
- list
- List all available attributes with all properties (default value, range, ...)
- snap [ jpeg | ppm ] [ full | win | widthxheight ] <filename>
- Capture one image.
- webcam <filename>
- Capture one image. Does basically the same as "snap jpeg win <filename>". Works also while avi recording is active. It writes to a temporary file and renames it when done, so there is never a invalid file.
- movie driver [ files | raw | avi | qt ]
- movie video [ ppm | pgm | jpeg | rgb | gray | 422 | 422p | rgb15 | rgb24 | mjpeg | jpeg | raw | mjpa | png ]
- movie fps <frames per second>
- movie audio [ mono8 | mono16 | stereo ]
- movie rate <sample rate>
- movie fvideo <filename>
- movie faudio <filename>
- movie start
- movie stop
- control xawtv's movie recorder.
- fullscreen
- Toggle fullscreen mode.
- showtime
- Display time (same what the 'D' key does in xawtv).
- msg text
- Display text on the on-screen display (window title / upper left corner in fullscreen mode).
- vtx line1 line2 [ ... ]
-
Display subtitles. It pops up a small window at the bottom of the screen.
It is intended to be used as an interface for displaying subtitles (often on
videotext page 150 in Europe, that's why the name) by external programs.
Every command line argument is one line, zero lines removes the window. You can colorize the text with the control sequence "ESC foreground background". foreground/background has the range 0-7 (ansi term colors). Example: "\03347 hello world " is blue on white. "\033" must be a real escape character, the string doesn't work. With the bash you'll get it with ^V ESC. vtx does also understand the ANSI tty escape sequences for color. - quit
- quit xawtv
- keypad n
- enter digit 'n'. That's the two-digit channel selection, entering two digits within 5 seconds switches to the selected station. Useful for lirc.
- vdr command
- send "command" to vdr (via connect on localhost:2001).
