This page is all about getting the Streamzap remote to work completely with XBMC.

Currently it includes only information on how to configure Streamzap on Linux.

Introduction

There are two ways you can set up Stream Zap remote to work with XBMC on Linux.

  • lircd
  • inputlirc

Linux Distros, XBMC and LIRC Versions Tested

LIRCD:

  • Gentoo and XBMC 9.11 (Camelot) and official app-misc/lirc-0.8.7 from portage
  • Ubuntu 10.04 and XBMC 9.11 (Camelot)
  • Ubuntu 10.10 and XBMC 10.0 (Dharma RC1) [buggy, but has workaround, see below]

Inputlirc:

  • Ubuntu 10.10 and XBMC 10.0 (Dharma RC1) [buggy, no workaround yet, see below]

Drivers

StreamZap is well supported in linux. However, I have seen drivers named differently. Here are the variations I've run into:

  • lirc_streamzap
  • streamzap (new ir_core implementation?)
  • rc_streamzap (new ir_core implementation?)

The configuraiton of LIRCD I've used in the past combine streamzap with lirc_dev.


ATTENTION UBUNTU USERS

As of Ubuntu 10.10, pressing any button on the remote will send the event twice to the system due to both the new and the old drivers currently compiled into the kernel.

Bug has been filed and fix is still pending: https://bugs.launchpad.net/ubuntu/+source/lirc/+bug/663651
There is also a forum thread on this: http://ubuntuforums.org/showthread.php?s=68f4cf4da940af13a8e70457b034938d&t=1595018

Workarounds:

There is a workaround if you are using a LIRCD setup, which works by disabling the Streamzap XInput device registered as keyboard.
However this does not work for me using the Inputlirc method (probably because they both use UDEV).

LIRCD

LIRCD: Installation and Configuration

Starting with LIRC 0.7.1 streamzap configuration has been included in the base package.

Ubuntu

During the install when prompted to select the IR Receiver, scrolldown and select "Streamzap PC Remote. 

sudo apt-get install lirc

It is very likely that lirc is already installed on your system. In that case, run the following to configure it.
When prompted to select the IR Receiver, scrolldown and select "Streamzap PC Remote. 

sudo dpkg-reconfigure lirc

The configuration will setup the following files like so:

/etc/lirc/hardware.conf 

REMOTE="Streamzap PC Remote"
REMOTE_MODULES="lirc_dev streamzap"
REMOTE_DRIVER=""
REMOTE_DEVICE="/dev/lirc0"
REMOTE_SOCKET=""
REMOTE_LIRCD_CONF="streamzap/lircd.conf.streamzap"
REMOTE_LIRCD_ARGS=""

...

START_LIRCD="true"


/etc/lirc/lircd.conf 

...

#Configuration for the Streamzap PC Remote remote:
include "/usr/share/lirc/remotes/streamzap/lircd.conf.streamzap"

Gentoo

Add streamzap to LIRC_DEVICES in /etc/make.conf 

...

LIRC_DEVICES="${LIRC_DEVICES} streamzap"

Install app-misc/lirc, add it to boot, and start up 

emerge -av app-misc/lirc
rc-update add lircd default
/etc/init.d/lircd start


It works out of the box. However if you need to edit the either lircd or remote configuration, use the following files:

LIRCD config: /etc/conf.d/lircd
Remote config: /etc/lirc/lircd.conf

Inputlirc

Inputlirc is "a daemon to utilize /dev/input/event*".

ATTENTION Ubuntu 10.10 user, there is currently a bug with using inputlirc with no work around.
See #ATTENTION_UBUNTU_USERS Section


UDEV Setup

First you have to create an own udev rule to ensure, that your device nodes are always the same.

We get the physical address from /proc/bus/input/devices: 

cat /proc/bus/input/devices

the output is something like this: 

...
I: Bus=0000 Vendor=0000 Product=0000 Version=0000
N: Name="Streamzap PC Remote Infrared Receiver (0e9c:0000)"
P: Phys=usb-0000:00:06.0-1/input0
S: Sysfs=/devices/virtual/rc/rc0/input4
U: Uniq=
H: Handlers=kbd event4 
B: EV=100003
B: KEY=3ff 0 0 0 fc000 1 0 0 0 0 18000 4180 c0000801 9e1680 0 0 0

...

What we need are the values behind Phys=. In my case usb-0000:00:06.0-1/input0

Now we write a new rules file for udev: 

sudo nano /etc/udev/rules.d/10-irremote.rules

and put the following content in: 

SUBSYSTEM=="input",ATTRS{phys}=="usb-0000:00:06.0-1/input0",SYMLINK="input/irremote0"

Now restart udev and trigger a new discovery: 

sudo restart udev
sudo udevadm trigger

Under /dev/input should now be a symlink call irremote0: 

ls /dev/input

Inputlirc Installation and Configuraiton

First you have to install inputlirc and lirc:
Please note that here we only need the lirc package because it contains "irw" and other utils. Please do not configure it for the Streamzap Remote 

sudo apt-get update
sudo apt-get install inputlirc lirc

Then you need to configure it properly: 

sudo nano /etc/default/inputlirc

and put the following content in: 

EVENTS="/dev/input/irremote0"
OPTIONS="-c -g -m 0"

The entries under EVENTS are the devices we created via udev. The OPTION entries mean the following:

-g Grabs the input from the devices, specified under EVENTS, so that no other application interferes with it.
-m 0 By default, all keycodes below 88 are filtered out. This setting ensures, that all keycodes are captured
-c Because some of the keys on the remote are mapped to keys with modifiers, this option maps this codes to single events.


Now restart inputlirc 

sudo /etc/init.d/inputlirc restart

You can now test the remote via 'irw': 

irw /dev/lircd

This is some sample output from irw when pressing buttons: 

6a 0 KEY_RIGHT irremote0
6c 0 KEY_DOWN irremote0
160 0 KEY_OK irremote0
8b 0 KEY_MENU irremote0
ae 0 KEY_EXIT irremote0
191 0 KEY_BLUE irremote0
18e 0 KEY_RED irremote0

Configuring XBMC

The last thing you need to do is let XBMC know to what buttons to respond. This is done via the Lircmap.xml: 

sudo nano ~/.xbmc/userdata/Lircmap.xml

and put the following content in: 

<lircmap>
  <remote device="irremote0">
    <play>KEY_PLAY</play>
    <pause>KEY_PAUSE</pause>
    <stop>KEY_STOP</stop>
    <forward>KEY_FASTFORWARD</forward>
    <reverse>KEY_REWIND</reverse>
    <left>KEY_LEFT</left>
    <right>KEY_RIGHT</right>
    <up>KEY_UP</up>
    <down>KEY_DOWN</down>
    <pageplus>KEY_CHANNELUP</pageplus>
    <pageminus>KEY_CHANNELDOWN</pageminus>
    <select>KEY_OK</select>
    <back>KEY_EXIT</back>
    <menu>KEY_MENU</menu>
    <title>KEY_RED</title>
    <info>KEY_GREEN</info>
    <skipplus>KEY_FORWARD</skipplus>
    <skipminus>KEY_BACK</skipminus>
    <display>KEY_YELLOW</display>
    <record>KEY_RECORD</record>
    <volumeplus>KEY_VOLUMEUP</volumeplus>
    <volumeminus>KEY_VOLUMEDOWN</volumeminus>
    <mute>KEY_MUTE</mute>
    <record>KEY_RECORD</record>
    <power>KEY_POWER</power>
    <blue>KEY_BLUE</blue>
    <one>KEY_NUMERIC_1</one>
    <two>KEY_NUMERIC_2</two>
    <three>KEY_NUMERIC_3</three>
    <four>KEY_NUMERIC_4</four>
    <five>KEY_NUMERIC_5</five>
    <six>KEY_NUMERIC_6</six>
    <seven>KEY_NUMERIC_7</seven>
    <eight>KEY_NUMERIC_8</eight>
    <nine>KEY_NUMERIC_9</nine>
    <zero>KEY_NUMERIC_0</zero>
  </remote>
