cec-ctl ā€” An application to control cec devices

Synopsis

cec-ctl [-h] [-d <dev>] [many other options]

Description

The cec-ctl tool is used to control cec devices. It is able to control almost any aspect of such devices covering the full CEC API.

Options

-d, --device=<dev>

Use device <dev> as the CEC device. If <dev> is a number, then /dev/cec<dev> is used.

-v, --verbose

Turn on verbose reporting.

-h, --help

Prints the help message.

-p, --phys-addr=<addr>

Use this physical address. The address can be a number (e.g. 0 or 0x11b1) or formatted as a.b.c.d where each component is a hex value from 0-f (e.g. 0.0.0.0 or 1.1.b.1).

-o, --osd-name=<name>

Use this OSD name. The maximum length is 14 characters.

-V, --vendor-id=<id>

Use this vendor ID. The vendor ID is a number from 0x0 to 0xffffff.

-C, --clear

Clear all logical addresses, leaving the CEC device unconfigured.

Start monitoring CEC traffic. This will monitor broadcast messages, messages directed to this CEC adapter and messages transmitted by this CEC adapter. Directed messages between other CEC devices are not monitored. This option requires root.

-M, --monitor-all

Start monitoring all CEC traffic. This will monitor all CEC messages, including directed messages between other CEC devices. This option requires root. Not all CEC devices support this monitoring mode. It will fallback to regular monitoring mode if it is not supported.

By default when sending a CEC message that expects a reply this utility will wait for that reply. With this option it will just send it without waiting for the reply.

-t, --to=<la>

Send the message to the given logical address (0-15).
