cec-ctl - An application to control cec devices
cec-ctl [−h] [−d <dev>] [many other options]
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.
−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.
−w, −−wall−clock
Show timestamps as wall-clock time. This also turns 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.
−l, −−logical−address
Show first configured logical address or nothing if the device is unconfigured. Useful for scripts, e.g.: la=‘cec-ctl -s -l‘
−L, −−logical−addresses
Show all configured logical addresses or nothing if the device is unconfigured. Useful for scripts, e.g.: las=‘cec-ctl -s -L‘
−C, −−clear
Clear all logical addresses, leaving the CEC device unconfigured.
−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. This option applies to the messages following this option. It acts as a toggle, so after you specify it a second time then the following messages will wait for a reply again.
−N, −−non−blocking
Transmit messages in non-blocking mode.
−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.
−r, −−show−raw
Show the raw CEC message in hex.
−s, −−skip−info
Skip the Driver Info output section.
−S, −−show−topology
Show the CEC topology, detecting which other CEC devices are on the CEC bus.
−P, −−poll
Send a poll message.
−T, −−trace
Trace all called ioctls. Useful for debugging.
−−cec−version−1.4
Use CEC Version 1.4 instead of 2.0 (the default).
−−allow−unreg−fallback
Allow fallback to Unregistered if all logical addresses are claimed. By default the adapter will remain unconfigured.
−−no−rc−passthrough
Disable the RC passthrough. By default remote control CEC messages are passed on as input keystrokes (the CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag is set when calling the CEC_ADAP_S_LOG_ADDRS ioctl), but this can be blocked by using this option.
−−reply−to−followers
The reply will be sent to followers as well. By default the reply will only go to the follower that initiated the CEC message. But if you have other followers running as well, then by giving this option they will also receive the reply.
−−timeout <ms>
Set the reply timeout in milliseconds (default is 1000 ms).
−−list−ui−commands
List all UI commands that can be used with option −−control−pressed.
|
−−tv |
Configure the CEC adapter as a TV. |
−−record
Configure the CEC adapter as a recording and playback device.
−−tuner
Configure the CEC adapter as a tuner device.
−−playback
Configure the CEC adapter as a playback device.
−−audio
Configure the CEC adapter as an audio system device.
−−processor
Configure the CEC adapter as a processor device.
−−switch
Configure the CEC adapter as a pure CEC switch.
−−cdc−only
Configure the CEC adapter as a CDC-only device.
−−unregistered
Configure the CEC adapter as an unregistered device. −−feat−record−tv−screen Signal the Record TV Screen feature.
−−feat−set−osd−string
Signal the Set OSD String feature.
−−feat−deck−control
Signal the Deck Control feature.
−−feat−set−audio−rate
Signal the Set Audio Rate feature.
−−feat−sink−has−arc−tx
Signal the sink ARC Tx feature.
−−feat−source−has−arc−rx
Signal the source ARC Rx feature.
−−rc−tv−profile−1
Signal RC TV Profile 1.
−−rc−tv−profile−2
Signal RC TV Profile 2.
−−rc−tv−profile−3
Signal RC TV Profile 3.
−−rc−tv−profile−4
Signal RC TV Profile 4.
−−rc−src−dev−root
Signal that the RC source has a Dev Root Menu.
−−rc−src−dev−setup
Signal that the RC source has a Dev Setup Menu.
−−rc−src−contents
Signal that the RC source has a Contents Menu.
−−rc−src−media−top
Signal that the RC source has a Media Top Menu.
−−rc−src−media−context
Signal that the RC source has a Media Context Menu.
−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.
−−monitor−pin
Start monitoring and analyzing the low-level CEC pin transitions. This is only possible if the device has the CEC_CAP_MONITOR_PIN capability. This option requires root. When in pin monitoring mode all 0->1 and 1->0 CEC pin transitions are monitored and analysed. This is effectively a cheap CEC bus analyzer.
−−monitor−time <secs>
Monitor for the given number of seconds, then exit. The default (0) is to monitor forever.
−−ignore <la>,<opcode>
Ignore messages from logical address <la> and opcode <opcode> when monitoring. "all" can be used for <la> or <opcode> to match all logical addresses or opcodes. To ignore poll messages use "poll" as <opcode>.
−−store−pin <to>
Store the CEC pin events to the given file. This can be read and analyzed later via the −−analyze−pin option. Use − to write to stdout instead of to a file.
−−analyze−pin <from>
Read and analyze the CEC pin events from the given file. Use − to read from stdin instead of from a file.
−−help−all
Prints the help message for all options.
