Installing Raspbmcsusessfully

Raspbmc = Rasberry Pi   XBMC

A friend recommended me this distro for running XBMC which was released by one of the developers of the XBMC project with specific optimizations to run on the Rasberry’s hardware. So I decided to test it and I explain here all have to do to install it, that indeed was a little problematic but successfully at the end.

Raspbmc from the installer

Raspbmc install error

The project’s page recommends to use the installer or Network Image, a python script which practically do the whole installing process, partitioning and doing the initial setup…or at least it tried to, because in my case it didn’t work due to my network connection at home didn’t help at all so I couldn’t download the image using the installer. Therefore I had to install the complete image of Raspbmc.

The complete image of Raspbmc

There’s another option offered on the project’s page which is to download the  whole image of Raspbmc of 235 MB called Standalone Image, but after extract it it sizes 1.4 GB roughly. This was an issue because my SD card’s capacity is  1 GB and I didn’t buy another one as I have a 320 GB hard drive just for the Rasberry Pi. Therefore I came up that I could shrink the image to fix my 1 GB SD card.

Repartitioning the image

In a similar way as explained in How to run Raspberry Pi from a USB hard drive article, I dumped the image into a 8 GB pen drive to be able to extract the /boot and the operating system or system file’s root partition. In order to copy the image to the pen drive you must first extract the image and later extract the image and the dump it as raw, as shown next:

# gunzip raspbmc-final.img.gz
# dd if=raspbmc-final.img of=/dev/sdb

If you check it with gparted you should see something like this:

Rasbmc image

Later using  gparted itself I had to resize the partition /dev/sdb2 to 800 MB roughly, so I could put the /boot de 74 MB as well in my 1 GB SD card.

Raspbmc

To extract the /boot partition from the pen drive you can do this:

# dd if=/dev/sdb1 of=raspbmc-final_boot.img

In a similar way extract the file system of 800 MB on the another partition:

# dd if=/dev/sdb2 of=raspbmc-final_fsext4.img

Initial setting

The initial setting it’s done by the installer, which is an script that ask some questions as networking parameters and such. Those values can be modifies later on XBMC with an script added for the Raspbmc:

Disk repartitioning

The installation detected the hard drive automatically but it didn’t let me partition it, in fact it erases everything and creates a unique partition which is mounted into /media withe the partition’s UUID . But I wanted three partitions: one for the operating system (/), other for the memory swapping  (swap) and the remaining space for data (/media/Toshiba320), and the /boot partition which must be in the SD card.

To partion the hard drive I deleted and created the partitions using fdisk. At the end the disk was distributed in this way:

Raspbmc

Then I edited the /etc/fstab to reflect the changes:

proc /proc proc defaults 0 0
devpts /dev/pts devpts rw,nosuid,noexec,relatime,gid=5,mode=620 0 0
#/dev/sda2 / ext4 defaults,noatime 0 0
UUID=e7db90716-9911-4fc8-95da-86c463f926a4 / ext4 defaults,noatime 0 0
UUID=70a55bca-9fdb-4073-87f6-c15fd7b351dc none swap sw 0 0
UUID=1ff934a3-f7ce-451f-9a07-0915e174a007 /media/Toshiba320 ext4 defaults 0 0
/dev/mmcblk0p1 /boot vfat defaults,noatime 0 0

And later I edited the file /boot/cmdline.txt to indicate that the operating system will be read from the hard drive instead of the SD card:

dwc_otg.lpm_enable=0 root=/dev/sda1 rootfstype=ext4 noatime quiet rootwait loglevel=1   persistent-logs sdhci-bcm2708.enable_llm=1 dwc_otg.microframe_schedule=1 dwc_otg.fiq_fix_enable=1

Disabling the Firewall

To disable the firewall that comes with a DROP rule by default on the Raspbmc, you have to edit the file /etc/network/if-up.d/secure-rmc, where you have to comment the following line:

iptables -A INPUT -i $IFACE -j DROP

You also can disable the firewall form the setting script of XBMC as show next:

Raspbmc settings

Remote control

I have a keyboard and a mouse connected to the Rasberry Pi but this is not practical, the ideal scenario is to have a remote. As the Rasberry Pi is connected to the WiFI the idea is to use this network  instead of IR or Bluetooh. Therefore I thought in an Android application and mi first choice was XBMC Remote but it seems it has some communication issues that makes XBMC goes crazy ( The Raspbmc version and other for Raspbian behaves the same), but at the end I used another application called Yatse which works properly and it looks better as you can see in the next screenshots I took from my phone:

Yatse XBMC remote  Yatse XBMC remote  Yatse XBMC remote

Performance

Comparing XBMC I had tried before on the Rasberry Pi, this version really runs well. It plays movies in several formats (.avi, .mkv, .mp4, etc) smoothly. On the other hand it has Linux inside so it’s my download center with qbittorrent-nox, and I use it for other testing purposes. And this is what XBMC reports as resources consumption:

Where to put my Rasberry Pi?

Rasberry TV

Due to I wanted to use my Rasberry Pi as a media center but I didn’t want to put lot of devices on my nightstand I came up with this idea. My Rasberry, a hard drive and a usb hub  look like corronchos (loricariidaes) but they are behind the TV.

Rasberry - Sticker

If you want to do something similar you can use stickers for holding photo frames (Command, Scoth, 3M, etc), and this way you can save some space and avoid to deal with a lot of devices on your room.

Installing SubDownloader on Raspberry Pi

SubDownloader 2.0.14 (on raspberrypi)

I’ve already install XBMC as my media center  and also qbittorrent Web as my “download” center. But one piece was missing: a subtitle downloader program. I knew about subdownloader, so I decide to give it a try on my Rasberry Pi but it is not on Raspbian repos…what can you do?

Easy, just add  Debian’s official repos for Sid and install it. Remember, Debian supports lot of architecture, even armhf. Let’s see how to do it…

Installing

  1. Edit file /etc/apt/sources.list to include sid’s repos:
    deb http://ftp.debian.org/debian/ sid main contrib non-free
  2. Update the package list:
    aptitude update
  3. Install SubDonwloader:
    aptitude install subdownloader
  4. Edit file /etc/apt/sources.list to delete sid’s repos (it’s enough by commenting the line with #):
    #deb http://ftp.debian.org/debian/ sid main contrib non-free
  5. Update the package list one more time:
    aptitude update

Now you can run the program on your Rasberry Pi locally or using ssh…but keep in mind it would run a little slow. Enjoy it!
