NAME

6       cec-ctl - An application to control cec devices
7

SYNOPSIS

9       cec-ctl [-h] [-d <dev>] [many other options]
10

DESCRIPTION

12       The  cec-ctl tool is used to control cec devices. It is able to control
13       almost any aspect of such devices covering the full CEC API.
14
15

OPTIONS

17       -d, --device <dev>
18              Use device <dev> as the CEC device. If <dev> is a  number,  then
19              /dev/cec<dev> is used.
20
21       -v, --verbose
22              Turn on verbose reporting.
23
24       -w, --wall-clock
25              Show  timestamps  as wall-clock time. This also turns on verbose
26              reporting.
27
28       -h, --help
29              Prints the help message.
30
31       -p, --phys-addr <addr>
32              Use this physical address. The address can be a number  (e.g.  0
33              or 0x11b1) or formatted as a.b.c.d where each component is a hex
34              value from 0-f (e.g. 0.0.0.0 or 1.1.b.1).
35
36       -o, --osd-name <name>
37              Use this OSD name. The maximum length is 14 characters.
38
39       -V, --vendor-id <id>
40              Use this vendor ID. The vendor  ID  is  a  number  from  0x0  to
41              0xffffff.
42
43       -l, --logical-address
44              Show  first  configured logical address or nothing if the device
45              is unconfigured.  Useful for scripts, e.g.: la=`cec-ctl -s -l`
46
47       -L, --logical-addresses
48              Show all configured logical addresses or nothing if  the  device
49              is unconfigured.  Useful for scripts, e.g.: las=`cec-ctl -s -L`
50
51       -C, --clear
52              Clear  all  logical  addresses, leaving the CEC device unconfig‐
53              ured.
54
55       -n, --no-reply
56              By default when sending a CEC message that expects a reply  this
57              utility  will wait for that reply. With this option it will just
58              send it without waiting for the reply. This  option  applies  to
59              the  messages  following  this  option.  It acts as a toggle, so
60              after you specify it a second time then the  following  messages
61              will wait for a reply again.
62
63       -N, --non-blocking
64              Transmit messages in non-blocking mode.
65
66       -t, --to <la>
67              Send the message to the given logical address (0-15).
68
69       -f, --from <la>
70              Send  message  from the given logical address. It is only neces‐
71              sary to use  this  option  if  multiple  logical  addresses  are
72              claimed.  By  default the first assigned logical address will be
73              used.
74
75       -r, --show-raw
76              Show the raw CEC message in hex.
77
78       -s, --skip-info
79              Skip the Driver Info output section.
80
81       -S, --show-topology
82              Show the CEC topology, detecting which other CEC devices are  on
83              the CEC bus.
84
85       -P, --poll
86              Send a poll message.
87
88       -T, --trace
89              Trace all called ioctls. Useful for debugging.
90
91       --cec-version-1.4
92              Use CEC Version 1.4 instead of 2.0 (the default).
93
94       --allow-unreg-fallback
95              Allow  fallback  to  Unregistered  if  all logical addresses are
96              claimed.  By default the adapter will remain unconfigured.
97
98       --no-rc-passthrough
99              Disable the RC passthrough. By default remote control  CEC  mes‐
100              sages    are    passed    on    as    input    keystrokes   (the
101              CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU flag is set when calling  the
102              CEC_ADAP_S_LOG_ADDRS  ioctl),  but  this can be blocked by using
103              this option.
104
105       --reply-to-followers
106              The reply will be sent to followers  as  well.  By  default  the
107              reply  will  only go to the follower that initiated the CEC mes‐
108              sage. But if you have other followers running as well,  then  by
109              giving this option they will also receive the reply.
110
111       --timeout <ms>
112              Set the reply timeout in milliseconds (default is 1000 ms).
113
114       --list-ui-commands
115              List  all  UI  commands  that  can  be  used  with option --con‐
116              trol-pressed.

186
187       -m, --monitor
188              Start  monitoring  CEC traffic. This will monitor broadcast mes‐
189              sages, messages directed to this CEC adapter and messages trans‐
190              mitted  by this CEC adapter. Directed messages between other CEC
191              devices are not monitored. This option requires root.
192
193       -M, --monitor-all
194              Start monitoring all CEC traffic. This will monitor all CEC mes‐
195              sages,  including  directed  messages between other CEC devices.
196              This option requires root.  Not all  CEC  devices  support  this
197              monitoring  mode. It will fallback to regular monitoring mode if
198              it is not supported.
199
200       --monitor-pin
201              Start monitoring and analyzing the  low-level  CEC  pin  transi‐
202              tions. This is only possible if the device has the CEC_CAP_MONI‐
203              TOR_PIN capability. This option requires root.  When in pin mon‐
204              itoring mode all 0->1 and 1->0 CEC pin transitions are monitored
205              and analysed. This is effectively a cheap CEC bus analyzer.
206
207       --monitor-time <secs>
208              Monitor for the given number of seconds, then exit. The  default
209              (0) is to monitor forever.
210
211       --ignore <la>,<opcode>
212              Ignore  messages  from  logical address <la> and opcode <opcode>
213              when monitoring.  "all" can be used  for  <la>  or  <opcode>  to
214              match all logical addresses or opcodes.  To ignore poll messages
215              use "poll" as <opcode>.
216
217       --store-pin <to>
218              Store the CEC pin events to the given file. This can be read and
219              analyzed  later  via the --analyze-pin option. Use - to write to
220              stdout instead of to a file.
221
222       --analyze-pin <from>
223              Read and analyze the CEC pin events from the given file.  Use  -
224              to read from stdin instead of from a file.
