NAME¶
cec-ctl - 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.
- -m, --monitor
- 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.
- -n, --no-reply
- 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).
- -f, --from=<la>
- Send message from the given logical address. It is only necessary to use
this option if multiple logical addresses are claimed. By default the
first assigned logical address will be used.
- -S, --show-topology
- Show the CEC topology, detecting which other CEC devices are on the CEC
bus.
- -T, --trace
- Trace all called ioctls. Useful for debugging.
