Lirc works, but XBMC does not respond to Infrared input

fmr · 04-02-2013, 02:14 AM

Hi, I have a strange situation with Lirc and XBMC:

Lirc is set up to work with my homemade IR receiver, plugged into /dev/ttyS0 on my media PC. (Ubuntu 10.04 with XBMC Eden)

Running irw gives the desired results: The correct button names (e.g. key_up) are displayed on stdout as I press them on the remote. XBMC starts as a service, xbmc-live, on boot. It does not respond to IR button presses at all. My configuration is as follows:

In /etc/lirc:

hardware.conf:

Enable debug mode: create file "/home/xbmc/.xbmc/userdata/advancedsettings.xml" with this content

Code:

<advancedsettings>
    <loglevel>1</loglevel>
</advancedsettings>

Run xbmc, press some keys on remote and then look into "/home/xbmc/.xbmc/temp/xbmc.log". Paste output here.

fmr · 04-04-2013, 04:02 AM

Great idea! I didn't know about the loglevel.

xbmc.log is attached, because it is too big for the post... xbmc.log

The sad thing is: All of the "DEBUG: LIRC: Update - NEW at" entries are keyboard presses on the tty2 console. I tested this by rebooting (for a clean log) and just going to tty2 (you'll see CTRL+ALT registered in the log file, but not F2), pressing up, down, left and right (on my actual keyboard) a few times, and checking the log. It seems that keyboard presses such as up, down, left, right, home, delete, etc. are registered as LIRC events, but not the Alphanumerical keys or ENTER.

However, none of my IR button presses show up in the log.

eSelix · 04-04-2013, 05:02 PM

It is weird, keyboard presses presented as LIRC events. Can you disable transmitter in hardware .conf, restart lircd and then test? Check also lirc logs

Code:

grep lirc /var/log/syslog

Check what you have started related to lirc

Code:

ps -Af | grep 'lirc\|ir'

Your keyboard is not connected by serial port?

Disabling the "transmitter" in hardware.conf fixed the weird Keyboard-presses-as-Lirc-commands problem!

Pressing buttons in XBMC still did nothing, and caused no events in the log.

I had an idea and did:

Code:

# service xbmc-live stop
# service lirc stop
# service lirc start
# service xbmc-live start

And my remote control worked in XBMC!! So it seems that Lirc should start before XBMC. Problem is, XBMC is an UpStart script, while Lirc is using sysvinit. I am very new to UpStart, and still find it confusing. I think I should convert Lirc to an UpStart service, and let XBMC depend on it. But I really don't know how!!

/etc/init/xbmc-live.conf:

Code:

# xbmc-live
#
# init XBMC environment
#

description     "XBMCLive"
author          "Luigi Capriotti"

start on (filesystem and stopped udevtrigger)

stop on runlevel [06]

script
	get_opt() {
		echo "$@" | cut -d "=" -f 2
	}

	CMDLINE=$(cat /proc/cmdline)

	#Process command line options
	XBMC_PARAMS=""
	for i in ${CMDLINE}; do
		case "${i}" in
		xbmc\=*)
		      XBMC_PARAMS=$(get_opt $i)
		      ;;
		esac
	done
	echo $XBMC_PARAMS > /tmp/xbmcliveParams

	if grep "boot=live" /proc/cmdline ; then
		# Relies on init scripts to mount boot device on a specified directory
		BOOTMEDIAMOUNTPOINT="/live/image"
	fi

	BOOTHOOKSDIRECTORY="/etc/xbmc"

	xbmcUser=xbmc
	# Read configuration variable file if it is present
	[ -r /etc/default/xbmc-live ] && . /etc/default/xbmc-live
	if ! getent passwd $xbmcUser >/dev/null; then
		xbmcUser=$(getent passwd 1000 | sed -e 's/\:.*//')
	fi

	# Executes pre-hooks (if any) in the System "Hooks" directory
	if [ -d $BOOTHOOKSDIRECTORY/live.d ]; then
	  for hook in $(find $BOOTHOOKSDIRECTORY/live.d -type f -perm /u=x,g=x,o=x | sort)
	  do
	        $hook $BOOTMEDIAMOUNTPOINT $XBMC_PARAMS  || true
	  done
	fi

	# Executes pre-hooks (if any) in the user "Hooks" directory
	if [ -d /home/$xbmcUser/.xbmc/live.d ]; then
	  for hook in $(find /home/$xbmcUser/.xbmc/live.d -type f -perm /u=x,g=x,o=x | sort)
	  do
	        $hook $BOOTMEDIAMOUNTPOINT $XBMC_PARAMS  || true
	  done
	fi

	runXBMC
end script

/usr/bin/runXBMC just launches XBMC in standalone mode.

Thanks for the help so far!

sysvinit scripts are normal executable files, so you can invoke it (with appropriate flags start and stop) in your "/etc/init/xbmc-live.conf" before running "xbmc" and remove links to lirc startup script in "/etc/rc*.d" directories.

Or you can add to xbmc upstart script to "start on" your custom event (for example "lirc") and emit it by "initctl emit lirc" in lirc script, after starting "lircd".

I had set in my xbmc.conf "start on stopped rc RUNLEVEL=[2345]". So it should start after all rc* scripts.
