| This page describes how to to use VLC media player with an infra red remote control on Linux. | Other "how to" pages |
Note: This article is about advanced lirc usage with VLC. For basic stuff please see Documentation:Modules/lirc.
The aim is to have your remote behave the same way as for a television remote: program +/-, volume +/-, jump to position 3 when button 3 is pressed,...
Build-in lirc commands are only for basic control in the movie-playing mode, but I need to use other commands from RC Interface - mainly "goto x" function. So the goal was to be able to use goto function with lirc.
VLC
Use a VLC version with lirc enabled.
Start-Up Script
#start/stop script for lircd+vlc for Kubuntu 6.10
start() {
echo "Starting lirc support..."
sudo setserial /dev/ttyS0 uart none #serial port down
sudo /sbin/modprobe lirc_serial #load module
sudo /sbin/modprobe lirc_dev #load module
sudo /usr/local/sbin/lircd --driver=default --device=/dev/lirc0 --output=/dev/lircd --pidfile=/var/run/lircd.pid --listen #run lirc daemon
sudo chmod 666 /dev/lircd #access
sudo irexec -d #daemon to pass ir commands
}
stop() {
echo "Stoping lirc support..."
sudo /usr/bin/killall -w lircd #kill lirc daemon
sudo /sbin/rmmod lirc_serial #unload module
sudo /sbin/rmmod lirc_dev #unload module
sudo setserial /dev/ttyS0 uart 16550A #serial port up
}
restart() {
stop
sleep 2
start
}
case "$1" in
'start')
start

echo "usage $0 start|stop|restart"

It is necessary to run vlc with rc interface to use all the supported commands (see vlc help). I use this script to run VLC with rc intf. Lircd is loaded and later unloaded. I have a desktop shortcut icon and I had to change properties of the shortcut to run in terminal. The other option is vlc --fake-tty option, but this uses 100 % CPU :-(
#/bin/bash
/home/ondra/.vlc/ovladac.sh start
vlc -I rc --rc-host localhost:12345 /home/ondra/playlist.m3u
/home/ondra/.vlc/ovladac.sh stopI use irexec to pass commands to VLC rc intf. Commands can be passed with netcat: echo "vlc_rc_command" | netcat localhost 12345 -q 1 (q means quit after 1 s). Commands are written in scripts, which are executed with irexec:
Here is a script, which is executed when remote button 1 is pressed. The others are similar.
$ cat play1.sh
#!/bin/bash
echo "goto 0" | netcat localhost 12345 -q 1.lircrc
- See also: An example .lircrc file included with VLC viewable online; it is not part of this guide but it may be more up-to-date
The last part of the .lircrc file.
There are defined actions for all requested buttons. irexec executes concerned shell script.

prog = irexec
button = 1
