LIRC stands for Linux Infrared Remote Control. It is required to use a generic* Remote Control with MythTV.
LIRC is a software package that gives your computer the ability to send and receive infra-red remote control signals when combined with appropriate hardware. Most distributions include LIRC packages, but you may have to compile it yourself if you wish to use certain features that the distribution packagers did not include.
- It should be noted that many people bypass the need for LIRC altogether, and simply use a "learning remote control" and a infra-red keyboard receiver. Train the learning remote control to output the appropriate keyboard press for each button/label. Linux and MythTV will see it as a keyboard and you have a simple and straightforward infra-red controller.
- LIRC is now built into the kernel and may not be required. Many MCE remotes may simply be recognized as a keyboard. This may or may not also require the use of "ir-keytable" based on your distro.
IR Reception (to MythTV)
In its most basic concept, you press the 'play' button on your remote control which sends an infra-red signal to a receiver connected to your computer. This receiver sends a signal to LIRC, which identifies that you hit the 'play' key on your remote and then generates a keystroke on your computer that instructs MythTV to play.
For the infra-red receiver, you have two choices about how you set it up to work with MythTV:
- The preferred method is to use mythtv native LIRC support, where mythtv reads ~/.mythtv/lircrc for its own key configuration
- An alternate approach uses irxevent which is an external program that can send key presses to MythTV as if you were pressing keys on the keyboard. irxevent reads ~/.lircrc (note the dot at the start of the filename)
The receiver may be connected to the computer via a serial port, USB, or by a dedicated chip built into a TV tuner card. Each different type of physical IR receiver has its own type of kernel module.
- The kernel module (C) uses /dev/lirc (typically) to emit the pulse-length information, which is then parsed by the lircd process. The LIRC daemon (D) then uses the information from /etc/lircd.conf (E) to convert the pulse-lengths into button press information.
- Lastly, all programs that use LIRC need a second configuration file which tells liblirc_client.so what button presses are to be translated into which commands for each client program using LIRC, including MythTV. Once the button presses have been converted into instructions by liblirc_client.so using the lircrc (F) file (~/.mythtv/lircrc in 0.20, but 0.21 will read ~/.lircrc as well), then they are ready to be used by MythTV. (G)
- Note that the button names in /etc/lircd.conf must match the "button" configuration names you use in your lircrc file, but are otherwise completely up to you. The translations between the button names and the mythtv's internal names is done in the .lircrc or lircrc file, in the "config" line for a button. The "config" names must match what mythtv is expecting, and for the mythtv native LIRC support the "prog" line must say "prog = mythtv". This can be debugged with ircat (invoked as `ircat mythtv`).
IR Transmission (from MythTV)
You might want to use a transmitter if you want MythTV to control a cable or satellite box so it can record the right shows on the right channels.
This process starts by configuring the video source in the Mythtv-setup program to use an an external channel changing program. More specifically, the channel changing script is a per capture card property that is specified in the Input Connections section of mythtv-setup. If you are using LIRC, this program will be a [LircChannelChanger channel changing script] that invokes LIRC's irsend command, passing it appropriate arguments to send the channel changing IR codes.
Let's say MythTV wishes to tune to channel 2 (either to record a scheduled show or because it was instructed by the user viewing live TV), it invokes the external channel changing program passing it '2' as an argument. The channel changing script turns that into an invocation of irsend, and LIRC transmits the appropriate codes via your infra-red transmitter.
The transmitter and receiver mentioned above are two separate devices (sometimes packaged into a single box). You cannot transmit through a receiver or receive through a transmitter.
- Using an IR Blaster with MythTV
- IguanaIR USB-based IR Transceiver
- Controlling a digital cable/satellite box using Fedora, MythTV, an IR Blaster and one instance of LIRC
LIRC with Multiple External Tuners
If you are using a system with multiple external tuners, you can use LIRC to control each one independently. The proper irsend command for each tuner can be placed in a separate channel changing script, and then specified as an external channel changing program for the appropriate video source in the Mythtv-setup program.
Normally, only a single LIRC transmitter is required as long as each of the tuners have mutually exclusive remote codes, and the LIRC transmitter can placed in the line of sight of all tuners' IR receivers. In this configuration, each tuner will need a "Remote Block" setting in the lircd.conf file and irsend simply needs the correct
REMOTE argument. This is probably the simplest solution to most multiple tuner systems.
However, there are some instances where unique control codes aren't possible, or simultaneous line of sight to the two receivers is not possible. In these cases, there are some options available:
- Build a Multi-Transmitter Homebrew Parallel Port Device and use irsend's
- Load multiple LIRC drivers using irsend's
--deviceoption. For some drivers, including lirc_serial (IR Blaster, etc.), this method won't work with multiple transmitters of the same type.
- Modify the source tree to support multiple instances of the LIRC driver and use 2 separate copies of irsend compiled.
- Use multiple IR emitters independently controlled by CommandIR Mini, a USB TX/RX combo device, with irsend's
- Multiple LIRC Drivers with multiple IR emitters of the same type without having to recompile lirc_serial.
Setting up LIRC can range from very easy to incredibly difficult. The difficulty level is likely related to what hardware you end up using for LIRC. There are several different hardware pieces for receiving and sending LIRC commands. A few are:
- The receiver that comes with your TV card. For example, the HD-PVR series from Hauppauge sometimes have a receiver.
- A Serial Port transmitter you can make yourself or buy for a small fee (called a homebrew transmitter)
- A commercially available USB receiver (e.g. Microsoft MCE remote control).
- A USB receiver you can make yourself.
- A Parallel Port transmitter and/or receiver you can make yourself.
- The built in receiver with Silicondust HDHomeRun that works over UDP. HDhomerun instructions

Migrating to LIRC 0.9.0+
As of 2.6.36, some infrared receiver drivers have been removed from LIRC and into the kernel. The following drivers are no longer available in lirc:
Other LIRC drivers have been moved to staging. For example, the lirc_i2c driver is in this part of the kernel now. These changes have been backported to the 2.6.35 kernel for Fedora 14, and the 2.6.32 kernel used by RHEL and derivatives.
For me this broke my existing lirc MCE USB setup. As of March 2011, I had to do the following to fix it using 2.6.37 on gentoo: Note: I recently (Oct 2012) tried this migration again and failed. The version of lirc in portage and from the lirc site no longer work for me as described below (YMMV). I have since stopped using lirc and am migrating to Sapphire.
- Enable the lirc driver in the kernel and rebuild. For the MCE USB remote this was under: Device Drivers -> Multimedia support - > Infrared remote controller adapters -> Windows Media Center Ed. eHome Infrared Transceiver
- Loaded the new mceusb driver (reboot or modprobe mceusb) which created /dev/lirc0. The previous non-kernel modules created the device as /dev/lirc so this is different. Therfore I had add -d /dev/lirc0 as an option to lircd when it started (for me this change was in /etc/conf.d/lirc) so the binary knew where to find the driver
- lircd ran without error but irw still didn’t show my keypresses on the remote. lircd -v showed 0.8.5 which is not compatible with the new drivers. I removed 0.8.5 then downloaded 0.9.0pre1 from the lirc site and installed it myself (there was no gentoo ebuild at the time). Note that this also installed drivers lirc_dev and lirc_mceusb which are the old drivers. They aren't needed so I deleted them on my system to avoid confusion in the future. After that I restart lircd and irw and could see my keypresses being captured.
- My last issue was that when I started mythfrontend, when I pressed up/down twice it would move 4 or 5 times. This was due to the irevents being interpreted as both lirc events and as keypresses in the kernel. This was fixed by running echo lirc > /sys/class/rc/rc0/protocols which forces them to be processed as lirc events only. Note that command needs to be run on every reboot, so it should be added wherever your distro runs such commands (gentoo is /etc/conf.d/local.start)
Here are things I DIDN’T have to do:
- update /etc/lirc/lircd.conf
If you have issues
- Run lsmod | grep lirc_ to check that the old modules aren't loaded
- Check that /dev/lirc0 is being created after mceusb gets loaded. If not look at dmesg after modprobbing mceusb it for clues
- run lircd in non deamon mode by using lircd -n <whatever other options you need>. This will keep the output to the console so you can see what’s happening.
- Make sure irw shows your key presses. If that doesn’t work, chances are nothing else will.
Again this all based on my experience on gentoo with 2.6.37 & 184.108.40.206. YMMV based on the distro in use - chances are some of this will be taken care of behind the scenes.
When using the PVR-250 (ivtv) video capture card as the platform to receive IR signals you will want to configure your kernel to support LIRC (CONFIG_LIRC=y), support staging (CONFIG_STAGING=y, CONFIG_LIRC_STAGING=y) and support the LIRC I2C driver as a module(CONFIG_LIRC_I2C=m). Kormoc has ebuilds available for LIRC 0.9.0 that should work sufficiently well with newer kernels. There is a bug filed to get a newer version of LIRC into portage. It has many votes, consider adding your vote there if you would like that or Kormoc's ebuild in portage.
Starting with Wheezy (testing) in April 2011, kernel 2.6.38 is available as the default linux-image and the required modules are included as modules.
In kernel modules are backported to Fedora 14 starting with the kernel 2.6.35,
Ubuntu 11.04 will ship with 2.6.38 and pre-release reports would indicate it will work.
Setting Up The Devinput Option
The in-kernel drivers support the ir keycodes, however, mythtv cannot currently use the interpreted codes so must use lirc as a bridge. The new drivers will break the configuration of pre 0.9.0 lirc setups. The devinput option uses the same setup for all of the receivers listed above.
This has been tested on Fedora 14 running 220.127.116.11-83 and Debian Wheezy (testing) with kernel 2.6.38-2.
- Install ir-keytable either from v4l-utils or the package of the same name (depending on distribution).
- Install the lirc-remotes RPM or lirc package to obtain various example lircd.conf files.
- Run ir-keytable to verify a driver has been loaded for your IR receiver
[root@myth1 ~]# ir-keytable Found /sys/class/rc/rc0/ (/dev/input/event3) with: Driver streamzap, table rc-streamzap Supported protocols: NEC RC-5 RC-6 JVC SONY LIRC other Enabled protocols: NEC RC-5 RC-6 JVC SONY LIRC other Repeat delay = 500 ms, repeat period = 33 ms
Alternative command. The protocols that are in brackets are enabled.
[root@myth1 ~]# cat /sys/class/rc/rc#/protocols [rc-5] [nec] [rc-6] [jvc] [sony] [lirc]
- Copy /usr/share/lirc-remotes/devinput/lircd.conf.devinput to /etc/lirc/lircd.conf
- Specify the devinput driver in /etc/sysconfig/lirc (LIRC_DRIVER="devinput") or in hardware.conf for Debian based systems.
- Determine which /dev/input device is available by looking in /dev/input/by-id.
- Specify the /dev/input device in /etc/sysconfig/lirc (LIRC_DEVICE="/dev/input/by-id/foo") or in hardware.conf for Debian based systems.
- Restart lirc.
- Check that your configuration is working by running irw and pressing some keys.
- You may need to change settings in mythtv. Under settings > general menu, look for the lirc setting. The device has moved in to /var/run/lirc/lircd.
Notes on Ubuntu/Mythbuntu 11.10 configuration:
- In hardware.conf edit REMOTE_DRIVER and REMOTE_DEVICE instead of LIRC_DRIVER and LIRC_DEVICE.
- Set LOAD_MODULES="false" in hardware.conf. For some reason with this set to "true", which is the default, the lirc service will not initialize properly.
The lircrc file defines the mapping between the buttons on your own remote (as defined in the lircd.conf) and the functions you actually want it to perform.
Keybindings has a list of all the keys used, which can be used in your lircrc file.
With native LIRC support, MythTV can use Qt keys, removing the prefix Qt::Key_. Not all of MythTV's key names match their Qt counterparts, however. Instead of Period and Comma, for example, use the symbols (. and ,) themselves. Instead of PageUp and PageDown, use PgUp and PgDown.
Keys can also have a modifier applied. These are case sensitive.
Tip: To find the exact syntax for a key (especially when it does not match QT keys), run the MythTV Frontend and go to Edit Keys. Select the function you want to invoke and look at the up to 4 key assignments at the bottom of the screen. The text displayed there will be what you need to use (for example PgDown).
For example, Setting the (Gray Hauppauge's) Power button to be Qt::CTRL Qt::Key_Escape:
begin prog = mythtv remote = Hauppauge_Gray button = Power config = CTRL+Escape end
"remote" is optional, but if you have multiple remotes configured in your lircd.conf e.g. for IR Blasting, you can use this line to make sure that only commands from the correct remote are used.
To configure the TV button to jump to Live TV by using the key sequence Qt::ALT Qt::Key_L,
- Add or modify your lircrc to contain
begin prog = mythtv remote = Hauppauge_Gray button = TV repeat = 3 config = ALT+L end
- Restart mythfrontend
- Go to Setup/Edit Keys/JumpPoints
- Select Live TV
- Press enter (until you see a dialog appear, that says it is waiting for a keypress)
- Press the TV button on your remote
Hopefully, you will now see Alt-L listed!
irw program to see whether LIRC and your remote are working before going any further. It shows what events are generated by your remote. This is very helpful!
The irw tool connects to the lircd socket and displays any recognized IR signals detected by the driver. If this works, then your hardware, driver and lirc.conf is working; all that remains is your application setup. If irw does not generate the expected output though, not all is lost -- see the mode2 command below.
You can enable logging for lircd with the -L option. Use this to see the results of clients connecting to lircd daemon. Compiling lircd with debugging enabled (-D option) allows you to see much more including parsing of the remote definitions.
# /usr/local/sbin/lircd --device=/dev/lirc/0 /etc/lirc/lircd.conf -L ~/lircd.log -D7
- The log file showing "accepted new client" immediately followed by "removed client" can indicate a a ~/.lircrc or ~/.mythtv/lircrc parsing error. Check the formatting.
Make the LIRC device static
If you have more than one input device on your system, the numbering may change from one reboot to the next. You can [use udev] to ensure the input device corresponding to your remote has a name that does not change across reboots.
You may notice that it only works if you have only one card with the same vendor ID. If you have more than one card from the same vendor, but with a different name, you can use the following line to create the /dev/input symlink:
ln -fs /dev/input/`cat /proc/bus/input/devices|grep -A 3 "Hauppauge Nova-S-Plus"|grep event|cut -d ' ' -f3` /dev/input/irremote
You should run this line before running lirc, for example add it to /etc/init.d/lirc here:
echo -n "Starting lirc daemon:" ln -fs /dev/input/`cat /proc/bus/input/devices|grep -A 3 "Hauppauge Nova-S-Plus"|grep event|cut -d ' ' -f3` /dev/input/irremote if $START_LIRCD; then
Using an udev rule may be more elegant, but I found this one liner to be more reliable.
The above failed for me for two reasons - one, my device is not an S-plus, and two, I have more than one of the same card. My small modification of the above one-liner should work for everyone:
ln -fs /dev/input/`cat /proc/bus/input/devices | grep -A 3 "Hauppauge" | grep event | cut -d ' ' -f3 | head -n1` /dev/input/irremote
The above fails on Ubuntu 10.04. A solution to this is: (Not tested on dual card setups)
ln -fs /dev/input/event$(cat /proc/bus/input/devices | grep -A 3 "Hauppauge" | grep Sysfs | sed -e "s/^.*\(.\)$/\1/") /dev/input/irremote
This makes a symbolic link in /dev/input called "irremote" this will always point to the Hauppauge event.
The command mode2 will give each separate pulse for button pushes. Some buttons have different pulses for pushing the button than for releasing the button. Using mode2 will show all pulses and is a lower-level lirc testing tool than irw.
Depending on your setup, lirc may be looking for either /dev/lirc0 or /dev/lirc, and the wrong one will obviously break things. You can use
ln -s /dev/lirc0 /dev/lirc or
ln -s /dev/lirc /dev/lirc0 to fix this.
If you know LIRC is working, and mapped correctly in the lircrc file, but is not doing anything in MythTV, you may want to check your LircSocket (frontend settings). This was a problem for me with MythTV 0.22 installed via atrpms on Centos 5.4. After installing lirc manually, I had to change the LircSocket setting from
/dev/lircd to get it to work. The frontend log should contain clues that it was not able to connect to the lircd socket.
/var/run/lirc/lircd is the default location for the lircd socket for lirc 0.8.6 and higher.
You may find that you are getting double hits for some of your buttons (example: arrows) but not all of your buttons. Xwindows may be listening to your remote as well as lircd. To disable X from listening, do the following:
First, verify that in fact X is listening to your remote by running
If you see your remote listed, take note of the device name, e.g. "Media Center Ed. eHome Infrared Remote Transceiver (147a:e017)"
Create a file called
/usr/share/X11/xorg.conf.d/90-mce_usb.conf and enter these contents:
Section "InputClass" Identifier "Ignore MCE_USB as Keyboard input" MatchProduct "Media Center Ed. eHome Infrared Remote Transceiver (147a:e017)" MatchIsKeyboard "true" Option "Ignore" "true" EndSection
Reboot for changes to take effect.
Key things to remember
- Set up
/etc/lircd.confto fit your remote.
- Don't try to use a lircrc file written for irxevent if you are trying to use MythTV native LIRC support, see Lirc on Ubuntu Dapper as the basis for your own file. Or search for mythtv/configfiles/hauppauge-lircrc-nativelirc to use it as a template.
- If you're using a PVR-350, at least, it won't work with stock LIRC. You need 0.7.0 (as mentioned in Jarod's Guide)
- If you're using a PVR-500MCE, please read this page: MCE_Remote
See MultiLIRC for my mods to the standard Debian Lenny lirc installation for running multiple lirc remotes and keeping everything separate.
Ubuntu/Mythbuntu lircrc generation
Mythbuntu provides a package that will intelligently parse your lircd.conf file and attempt to create valid button mappings for use in MythTV and other media player applications. Note that the use of this package is contingent on your remote being properly installed and working. You can install and invoke this package as follows:
sudo apt-get install lirc mythbuntu-lirc-generator mythbuntu-lirc-generator
Restart mythfrontend. Your remote should now work with MythTV!
Please note that there is a bug which causes duplicate mappings to be generated. This can cause remote input to be processed twice. For instance if you press "down" and the menu selection moves down two items or if you press "pause" and the recording immediately pauses and then starts playing again. For more information please see the the Ubuntu Launchpad bug 779835.

Lirc configuration on Debian Wheezy (testing) for Hauppauge PVR-350 and A415-HPG-WE remote
This text is a manual for the configuration. It worked on my machine with the hardware described. Obviously, there is more than one remote out there for the PVR-350, all with slightly different settings. There is also lots of descriptions for older lirc versions. These are almost useless for lirc 0.9.0 as part of the kernel.
AMD Phenom X2 box

To find out what to enter into DEVICE="", check out
Look for section where you can find this information:
I: Bus=0018 Vendor=0000 Product=0000 Version=0000 N: Name="i2c IR (Hauppauge WinTV PVR-350" P: Phys=i2c-0/0-0018/ir0 S: Sysfs=/devices/virtual/rc/rc0/input10 U: Uniq= H: Handlers=kbd event8 B: PROP=0 B: EV=100013 B: KEY=c0010 201080400000000 0 30200a000 18000004801 9e000000000000 ffc B: MSC=10
The line starting with H says event8. Meaning that we can find our remote under /dev/input/event8
copy lircd.conf.devinput from /usr/share/lirc/remotes/devinput to /etc/lirc/:
cp /usr/share/lirc/remotes/devinput/lircd.conf.devinput /etc/lirc/lircd.conf
Set up key map for A415-HPG-WE remote
I've got the almost correct keymap for the remote from /lib/udev/rc_keymaps and copied it into /etc/rc_keymaps/:
cp /lib/udev/rc_keymaps/haupp /etc/rc_keymaps/
The difference is, that all codes start with 0x1e.., while 0x00.. would be correct for my remote. File should though look like this (i've called this file haupp350):
# table haupp, type: UNKNOWN 0x0000 KEY_0 0x0001 KEY_1 0x0002 KEY_2 0x0003 KEY_3 0x0004 KEY_4 0x0005 KEY_5 0x0006 KEY_6 0x0007 KEY_7 0x0008 KEY_8 0x0009 KEY_9 0x000a KEY_KPASTERISK 0x000b KEY_RED 0x000c KEY_RADIO 0x000d KEY_MENU 0x000e KEY_GRAVE 0x000f KEY_MUTE 0x0010 KEY_VOLUMEUP 0x0011 KEY_VOLUMEDOWN 0x0012 KEY_CHANNEL 0x0014 KEY_UP 0x0015 KEY_DOWN 0x0016 KEY_LEFT 0x0017 KEY_RIGHT 0x0018 KEY_VIDEO 0x0019 KEY_AUDIO 0x001a KEY_MEDIA 0x001b KEY_EPG 0x001c KEY_TV 0x001e KEY_NEXT 0x001f KEY_BACK 0x0020 KEY_CHANNELUP 0x0021 KEY_CHANNELDOWN 0x0024 KEY_LAST 0x0025 KEY_OK 0x0029 KEY_BLUE 0x002e KEY_GREEN 0x0030 KEY_PAUSE 0x0032 KEY_REWIND 0x0034 KEY_FASTFORWARD 0x0035 KEY_PLAY 0x0036 KEY_STOP 0x0037 KEY_RECORD 0x0038 KEY_YELLOW 0x003b KEY_GOTO 0x003d KEY_POWER
Then i've edited /etc/rc_maps.cfg to look like the following:
* * /etc/rc_keymaps/haupp350
The above is the only uncommented line
Time for a restart now (or try restarting just udev?)
Invoke irw, and press buttons on your remote to check if everything is working. You should get an output like this:
0000000080010193 00 KEY_CHANNELDOWN devinput 0000000080010071 00 KEY_MUTE devinput 00000000800100a7 00 KEY_RECORD devinput
Now, we have to adjust ~/.lircrc. The name like KEY_CHANNELDOWN has to be attached to the appropiate keyboard key for mythtv. My .lircrc looks like this (this is an evolved file from other tutorials and howto's):
# lircrc Hauppauge PVR-350 with lirc 0.9.0 # save it in ~/.lircrc # begin mythtv begin prog = mythtv button = KEY_POWER config = Esc # mode = irexec repeat = 0 end begin prog = mythtv button = KEY_GOTO # Swap the PiP windows config = N end begin prog = mythtv button = KEY_1 config = 1 end begin prog = mythtv button = KEY_2 config = 2 end begin prog = mythtv button = KEY_3 config = 3 end begin prog = mythtv button = KEY_4 config = 4 end begin prog = mythtv button = KEY_5 config = 5 end begin prog = mythtv button = KEY_6 config = 6 end begin prog = mythtv button = KEY_7 config = 7 end begin prog = mythtv button = KEY_8 config = 8 end begin prog = mythtv button = KEY_9 config = 9 end begin prog = mythtv button = KEY_BACK config = Esc end begin prog = mythtv button = KEY_0 config = 0 end begin prog = mythtv button = KEY_MENU config = M end begin prog = mythtv # This is the Red key # We'll use it for "Delete" button = KEY_RED config = D end begin prog = mythtv # This is the Green key # We'll use it for "Information" button = KEY_GREEN config = I end # Note the "repeat =" strings in the volume and channel. # This means that if you hold down the key, every nth instance will be # passed.

Hints for trouble shooting
The correct scancodes can be found out using evtest for scancodes:
