====== OSMC Media Center ======

{{composants:rpi.png?250}}

===== Summary =====

A Raspberry Pi is ideal to build a home media center, for instance, coupled with a NAS.

===== Sources management ======

In the sources menu, when a keyboard is connected, pressing 'C' will bring up contextual menu for a selected item. This is useful to edit or remove sources.

NFS sources have to be properly configured on the server side (e.g. on the NAS if using one) and shared folders have to have permissions set up properly on remote hosts.

Sources management works best when using static IPs on the internal network and configuring the sources with direct IP addresses and proper protocols. For example :

<code>
nfs://192.168.1.64/volume/video/
smb://192.168.1.84/folder/
</code>

===== IR Remote control =====

//IR remotes generally emit in a wavelength around 940nm, so we need a IR sensor. It's invisible to the eye but cameras (such as smartphones) can see a dim purple light.//

==== Setup ====

  *MyOSMC > Pi Config > Hardware Support
    *Note GPIO pins
    *we need gpio_in_pin
  *Plug the IR sensor accordingly (see below)
    *Vin on 3.3V or 5V
    *GND on RPi GND
    *OUT on gpio_in_pin (18 on mine in 12/2017)
  *MyOSMC > Remotes
    *Active appropriate script according to your remote
    *If no script exists, clone a script and edit it or create one with irrecord command

==== irrecord ====

Log into a shell : EXIT >> Esc. key (default user/pass : osmc/osmc)

Stop lircd service

<code>
sudo systemctl stop lircd_helper@lirc0
</code>

Launch irrecord specifying correct device (here /dev/lirc0)

<code>
irrecord -d /dev/lirc0 /home/osmc/lircd.conf
</code>

Reboot lircd service

<code>
sudo systemctl start lircd_helper@lirc0
</code>

Script will ask to press certain buttons. Full list can be found [[https://www.ocinside.de/modding_en/linux_ir_irrecord_list/|here]] (2017)
