RaspBMC vs OpenELEC vs XBian: The Final XBMC Raspberry Pi Shootout

XBMC Final(ly) on the Raspberry Pi

Update 2 March 2013: OpenELEC 3.0 Final now used for the shootout and also tested the 12.1 update for RaspBMC. Boot-time of RaspBMC seems to have improved slightly but OpenELEC didn’t improve noticably over the 5th Release Candidate.

September last year I compared the three major XBMC versions for the Raspberry Pi. That comparison was based on early development versions of RaspBMC, OpenELEC and XBian but they already performed surprisingly well.

The latest builds of all three distributions run on the final version of XBMC 12 that was released at the end of January. Normally OpenELEC was the first to release a new version after each XBMC milestone release but this time RaspBMC was the first distro with a final version, followed by OpenELEC 7 weeks later while XBian is still under development. Yet all three have improved a lot so your XBMC experience should become even better. Time to line them up again and see if OpenELEC is still my favorite choice.

I performed all tests with a 4 GB 10x SD card, Synology NAS, Samsung LCD TV, Onkyo DTS receiver and 100 MBit network as during the previous shootout. This time the latest  versions of the XBMC distributions (OpenELEC 3.0 Final, RaspBMC Final with XBMC 12.1 and XBian 1 Alpha 5) were used. Although some distributions overclock your Raspberry Pi by default I ran all comparisons at the default frequency of 700 MHz.

Installation

Installation of the early versions of the three distributions installation was far from ideal. RaspBMC was the only flavor that came with an installer but the installation took well over 20 minutes. XBian and OpenELEC required you to write an image to your SD card with third-party software or Linux. The upside was that this process only took a few minutes.

XBian

The final version of XBian comes with its own installer. This drops the need to install Win32 Disk Imager and ensures a fast and smooth installation.

The installer works like a charm. You can select a version of XBian (which it will download if you haven’t already done so) and select the drive on which you want to install XBMC. Installation is really a matter of minutes and after that you can insert the SD card into your Raspberry Pi and boot it up.

XBian needs to do some initial setup on the first boot and after that it’s begins to load and start up XBMC. The whole process including initial setup takes about 1 minute 30 seconds which is pretty fast. A nice progress indicators show how fast your Raspberry Pi is booting.

RaspBMC

RaspBMC comes with a new and improved installer. Now you can configure networking during the installation. This is a good addition since I prefer a fixed IP address for reasons I’ve described in my Perfect XBMC Setup post. You can also configure wireless networking here. Finally the installer can install RaspBMC to USB devices and NFS shares for improved performance. something I haven’t tried out yet.

Preparing the SD card takes less than a minute and after that installation continues on the Raspberry Pi itself. This takes a lot of reboots and roughly 19 minutes of your time. At the end of the installation RaspBMC asks you in what language you want to run XBMC. A nice feature but does it really require yet another reboot?

So apart from the network config and the option to install RaspBMC on USB and NFS drives not too much has changed in the last 5 months. The installation is still rather time consuming but this isn’t too bad since it’s something you’ll probably only do once.

OpenELEC

The final version of OpenELEC still doesn’t come with an installer. For the the more experience users this won’t be a problem but newer users can be intimidated by this. Installing using Win32DiskImager (as described here) is still very fast and within 5 minutes you can have your Pi up and running.

Starting Up

If you don’t plan to run an always-on Raspberry Pi setup the time it takes to start op your XBMC version is an important issue. In the first shoot out the differences were pretty big and the slowest contestant took twice as long to start-up as the fastest of the three.

RaspBMC start up time

With one minute and thirty seconds RaspBMC was by far the slowest during the last line up. The final version of XBMC is 25 seconds quicker and starting up now takes slightly less than a minute. Not bad considering it’s running a full version of Linux. The UI is somewhat slower right after starting up but this improves quickly after that.

OpenELEC start up time

OpenELEC is still the fastest when it comes to starting up. It takes 50 seconds from the moment you plug in the power adapter until XBMC is booted and ready for action.

XBian start up time

The earlier version of XBian I tested started up in about 45 seconds. The most recent incarnation of XBian takes just under a minute before it’s ready for action. I don’t know why it needs 15 seconds more (using a faster SD card) than the earlier builds but it sure takes away one of the biggest advantages over RaspBMC.

User Interface

The first comparison of the three major XBMC flavors on the Raspberry Pi already revealed the Pi’s weak point. Its lack of raw processor power means it has a hard time presenting a smooth user interface. The Betas build ran at a maximum of 35 frames per second while the ARM CPU of the Raspberry was stretched to the max constantly.

All three versions have made huge strides forward but there is a good explanation for the improvements. All three distribution now limit the user interface resolution to 720p. The output will still be 1080p but the UI renders in 720P and up-scaled to 1920 x 1080. This makes a pretty big difference but a results in a blurrier user-interface  Don’t worry! Videos playback is in full 1080p so your lovely Blu-ray rips will still look great.

On top of the resolution limit RaspBMC and XBian by default overclock your Raspberry Pi to respectively 800 and 840 MHz. This gives the UI an extra push. But like said before all tests were performed without any overclocking. So all results below are with the CPU running at 700MHz.

RaspBMC UI

The first distribution I tested was RaspBMC. Five months ago it just managed to catch up with the other two with the installation of the latest nightly and ran at 35 FPS with a CPU load of nearly 100%.

I was pleasantly surprised when I started playing around with the final version of RaspBMC. The resolution limitation really helps and the user interface felt noticeably smoother than the last time. The only time I had to wait was while opening the list of my music albums. System information shows a healthy 50 FPS but strangely enough the CPU is almost fully idle.

The CPU being almost completely idle is due to a bug which has broken the CPU monitor. Even when playing MP3s it is still running around 0 percent while frame-rate has dropped significantly due to the CPU power required for playback.

XBian UI

The XBian UI runs pretty smooth and hits 51 frames per second. Unfortunately the UI became unresponsive a few times while navigating through the settings menu and the various media screens. Especially exiting the XBian Setting menu can cause some serious freezes of the system.

Where RaspBMC shows the wrong CPU load XBian decided to not show CPU load at all. This makes sense because we already know the system load is over 90% while XBMC tries to run the UI at 60 frames per second.

OpenELEC

OpenELEC runs the UI very smoothly as well running at around 50 frames per seconds. Strangely enough after watching a movie the UI frame-rate drops to about 30 for a while after which it climbs up to 50 again. But the UI stays responsive all the time and using OpenELEC is overall a good experience.

Video Playback Performance

By far the most important part of a media center is video playback. It doesn’t matter how great the UI looks and what incredible features it has if the video playback is no good.

Fortunately all three distribution do really well and have no difficulty playing the 1080P x264 DTS test video over the network. Even when the Raspberry Pi has to do the DTS decoding playback is still smooth. Also skipping forward or backward seems to go faster that with the earlier test builds.

Music Playback

Next to playing videos your Media Center will probably also be used to listen to your music. Of course all three distributions have no trouble playing your MP3 or FLAC files. There is a problem with audio playback though.

XBMC on the Raspberry Pi doesn’t seem to support gapless audio playback. All three distributions perform the same here so it is most likely an XBMC issue. On my setup the pause is just long enough for my AV Receiver to drop the HDMI audio connection. When the next song start playing it needs to renegotiate the HDMI connection setting and misses the first 2 seconds of the song. Pretty annoying.

Features

All three XBMC flavors come with a whole range of features we already saw in the previous test. You get things like Airplay, CEC and PVR straight out of the box with all three. Also they all feature an auto updater and

On top of that each distribution has its own custom settings menu in which you can fine tune and tweak Raspberry Pi specific settings.

RaspBMC

The Raspbmc Settings menu lets you configure your network  setting for both wire and wireless networking. From the menu you can also install Nightly Builds and switch between installed versions. This is a nice feature but doesn’t seem to be aimed at the average XBMC user.

The next settings tab is for overclocking settings which removes the need to manually write config files for overclocking. Turning off overclocking unfortunately results in an annoying warning about the config file not being the same as the module configuration every time you start-up. This tab also lets you turn on or off services like SSH, Samba, FTP. Here you can also change your password and turn of the “Unsafe Shutdown” warnings you get when you (just like me) shut down your Pi by unplugging the power adapter.

Another interesting feature is the Auto Updater that downloads XBMC straight from the source and then decompresses and installs it. This works very well but is rather time-consuming. Also you don’t know when it is about to happen and you have no way of skipping it. So if you want to quickly show something to a friend that’s too bad.

XBian

XBian also has its own settings menu. The look and feel of this menu matches the Confluence skin and really blend in very nicely. But that great look and feel apparently comes at a price. Each time you open the menu XBian has to generate the windows and gives you a message saying this may take up to a minute… and it does. Very annoying.

Also the menu is nowhere near as rich in features as that of RaspBMC. XBian just lets you configure your networking, license keys, services and check for updates. Ticking the Advanced Settings box changes this radically however. In Advanced mode you can configure overclocking settings and advanced HDMI settings like described in my XBMC installation and configuration guide. You can even switch kernels if you’ve got more than one installed.

OpenELEC

Even though OpenELEC has it’s own configuration section as well it doesn’t compare to the other two. You’re limited to configuring your network, services and automatic updates. To tweak any of the other settings you need to get your hands dirty and edit the config files in a text editor.

Conclusion

The most important conclusion is that all three distributions have made impressive progress and by now there are no more excuses not to run a Raspberry Pi as your primary Media Center “PC”.

RaspBMC has made the most progress and apart from the small bug with the pop-up window when changing the default overclock setting it works flawlessly. Also the decreased boot time takes away one of the bigger downsides of this distribution.

Installation of RaspBMC is still rather time-consuming but you’ll only do this once so this isn’t that much of a problem. Hiding some of the more advanced features by default (just like XBian does) probably would have been a good idea though.

The other two distributions are pretty solid too but just not as good as RaspBMC at this moment. XBian absolutely lost some points for the config menu that takes over a minute to open. Also it felt somewhat laggy at times. OpenELEC is still fast but its lack of configuration options in the UI and the fact that it has no installer put it behind RaspBMC.

Raspberry Pi Print And Scan Server part 2: CUPS and AirPrint Setup

In part 1 of this series I explained how to set up a Raspberry Pi powered scanner that could do tricks like one-button-dropbox-scanning. But the goal was to create a Scan and Print server. So let’s take a look at setting up the Printing part so you can share your printer over the network. On top of that let’s add AirPrint so you can print straight from your iPad.

CUPS

For the print serve part we’ll be using CUPS, the most well-known print server package on Linux. Since we only use our Pi as a Scan and Print server it will run CUPS without any problems.

To install CUPS just log in to your Raspberry Pi and enter sudo apt-get install cups . After that we need to add our login user Pi to the printer group. You can do so with sudo usermod -a -G lpadmin pi . 

The whole idea of a print server is that you want to share your printer over the network. Since network sharing is disabled by default you need to enable it. You also need to enable remote access to the management web console. To do this all in one go you can use the command: sudo cupsctl –share-printers –remote-printers –remote-admin .

You can now add and configure your printer in the web admin console. Open a browser an navigate to https://<ip-of-your-pi>:631/admin/ . You can ignore the warning about the dodgy certificate. It’s not like anyone already hacked your Pi or something.

CUPS web admin console

In the management console click on Add Printer. You need to log in with your pi account. Pick the right local printer and push Continue. Now give your printer a suitable name and make sure you check the Share Printer option. On the next screen pick the right driver (just go for the recommended one that matches you model) and push Add printer.

After setting the default values CUPS will tell you the printer was added successfully. You can click on the link or wait for 5 seconds to go to the printer overview page (which is something like https://<ip-of-your-pi>:631/printers/Brother_HL-2030_series depending on the name you gave your printer during the setup).

Installing the printer on Windows machines

To install the printer on a Windows machine open the Devices and Printers menu and select Add printer. Click on the “The printer that I want isn’t listed” option and click on the “Select a shared printer by name”. Here you need to enter the address of your printer overview page in plain http (so without the s), http://<ip-of-your-pi>:631/printers/Brother_HL-2030_series . After clicking next and selecting the right printer driver you’re ready to start printing.

AirPrint

We could just stop here and enjoy our newly created print server. But if you own an iPad wouldn’t it be cool if it could print straight to your newly shared network printer? In order to do so you need to install AirPrint on the Raspberry Pi.

Since you’ve already got CUPS running and configured your printer correctly (if you haven’t you should do so before continuing) setting up AirPrint is pretty straightforward. All you need is the Avahi deamon, some extra CUPS packages and the AirPrint generation script created by T J Fontaine.

Let’s start with the extra packages and the deamon. To install these type sudo apt-get install avahi-daemon python-cups cups-pdf. And to download the generation script from GitHub use the command wget https://raw.github.com/tjfontaine/airprint-generate/master/airprint-generate.py .

Apple changed the AirPrint protocol slightly in iOS 6 and to make it work you need two additional config files. To create these use the following two commands:

  • sudo echo ‘image/urf application/pdf 100 pdftoraster’ > /usr/share/cups/mime/airprint.convs
  • sudo echo ‘image/urf urf string(0,UNIRAST<00>)’ > /usr/share/cups/mime/airprint.types

The last step is to generate the AirPrint service file for your printer and restart the Avahi deamon. To do so use these commands:

  • sudo python airprint-generate.py -d /etc/avahi/services/
  • sudo service avahi-daemon restart

Now grab your iDevice and open an app that supports AirPrint (Mail or Safari will do fine). To print click on the share button at the top and choose Print. Your printer should show up and now you’re ready to print from your iPad. If it doesn’t work straight away try rebooting your Raspberry Pi.

Because the Raspberry Pi has limited memory and CPU power printing over AirPrint is pretty slow. For me this isn’t a problem since I’ll only use it to print and address, directions or a to-do list. But if you want to print larger documents you’ll need a fair amount of patience. Also the generate script is printer specific so if you ever add a new printer to your config you need to repeat the last two commands.

This concludes part two of this series and by now you’ve configured your Raspberry Pi as a full scan and print server. In the next parts I’ll be adding more features like controlling your scanner from your smartphone or browser and  a copy function (with its own button of course).

Raspberry Pi Print And Scan Server part 1: Scan Straight To Dropbox

This project initially started out as a Raspberry Pi printer server. Looking for a new printer I didn’t feel like paying an additional 60 euros for a network enabled printer. I knew our beloved Raspberry Pi could do that job just fine. While waiting for my new printer to arrive I decided to also hook up my old scanner and make it a print and scan server. The scanner part is now finished and can scan straight to Dropbox with the push of a button. Not bad for a 35 euro print and scan server.

I’ll admit right away inspiration for the scanning part this project came from a few other great projects out there (references at the bottom of this post). But non of those projects did exactly what I had in mind and also weren’t described well enough to start building straight away.

The primary goal of this first part of the project was to scan without turning on a computer and pick up the result somewhere. As a  bonus I figured it would be nice to see the progress of your scan jobs. So I created my own hardware with a Scan button and progress indication LEDs, selected the right programs and wrote scripts to glue everything together. Let’s see how it’s done.

NOTE: Before reading any further (and attempting this yourself) you should know the GPIO pins of the Raspberry Pi are not protected against high voltages. Incorrect wiring can result in a framboise flambée (yep, a Fried Pi). The hardware isn’t complex but only attempt this if you’re sure you know what you’re doing. I’m in no way responsible for any damage inflicted on your Raspberry Pi.

The first thing to do is check if you’ve got all required ingredients. This project uses the following hardware:

  • A Raspberry Pi model B (revision / memory is not important)
  • An SD card (2 GB or more)
  • A Sane compatible scanner
  • Components for GPIO interface board (breadboard, push button, 6 LEDs (5 green, 1 red), 10K Ohm resistor, 300 Ohm resistor, jumper cables)

If you’ve got all the required hardware you should start of with a clean Raspbian “Wheezy” installation. Make sure you re-size the partition (more space for programs and storing scans) and enable SSH. Also give your Raspberry a fixed IP address because it is a server after all.

Once Raspbian is up and running you can start installing the required programs. For scanning images we’ll use Sane. Login to your Pi (directly or over SSH) and type: sudo apt-get update followed by sudo apt-get install sane . After that you need to fix permissions so your user is allowed to scan. To do so enter: usermod -a pi -G scanner . Now it’s time to check if Sane is setup correctly. Type scanimage –L and Sane should list your scanner. Great.

The number of image formats Sane can output is limited. We’ll install ImageMagick so we can convert our images to almost any format. The current version of my setup only supports jpegs but future versions should also allow you to export as (multi page) PDF. To install ImageMagick simply type: sudo apt-get install imagemagick .

While other projects use email or network shares to distribute scanned images I thought it would be really cool if you could upload them directly to Dropbox. Not much information could be found about this and there is also no official Raspberry Dropbox client.

Fortunately Andrea Fabrizi created a great Bash script for uploading files to Dropbox which we will use. Download the script with the following command:

wget https://raw.github.com/andreafabrizi/Dropbox-Uploader/master/dropbox_uploader.sh

After that make the script executable ( sudo chmod +x dropbox_uploader.sh ). We’ll call this script later from our own script. For now you can leave the script alone.

Since we’ll be using Python to glue everything together and control the LEDs you need to install the RPi.GPIO library. You can do this, surprise surprise, using apt-get:

  1. sudo apt-get update
  2. sudo apt-get install python-dev
  3. sudo apt-get install python-rpi.gpio

The last step can probably be skipped since it is already part of the python-dev package.

The last piece of software needed is the python script to make all the magic happen. I’ve made this script, named scan.py, available on GitHub (raspberry-pi-scan-print-server). It should be placed in your home directory (/home/pi). To do so login to your Pi if you haven’t already and go to your home directory (cd ~) and run the command wget https://raw.github.com/gijsbertpeijs/raspberry-pi-scan-print-server/master/scan.py .

With the software all in place it is time to focus on the hardware. Like said before: the scheme isn’t too difficult but if you don’t feel comfortable doing this just don’t. It’s not worth frying your Pi over this and in the future I’ll write a post about controlling the scanner with your phone anyway.

The circuit we’re trying to make looks like this:

Raspbery Pi scan server circuit

Raspbery Pi scan server circuit

Basically it’s a switch hooked up to GPIO pin 8 using a 10K Ω pull up resistor for a clear On/Off signal. The 6 LEDs are connected to GPIO pins 10, 11, 12, 13, 15 and 16 with a 300Ω resistor to keep voltages at an acceptable level. The resistor for the LEDs should be roughly 300 Ω but a bit more or less doesn’t hurt. Also make sure you connect the LEDs in the right way (minus towards the GPIO pins).

Once you circuit board is finished you can hook it up to your Raspberry Pi (make sure you hook up all pins correctly before powering your Pi. Especially pin 1 (right next to the P1 marking on your Raspberry Pi) is very important.). Once the Raspberry Pi is booted login and type sudo python scan.py (root is required because we’re fiddling with the GPIO connector). The first LED should turn on (System Ready) and after you push the switch your scanner should start scanning.

When the scanner is finished the next LED will go green indicating the tiff file is being converted to a (much smaller) JPEG. After that the Dropbox upload script will kick in. The first time you run it you need to follow the simple on-screen instructions to connect the Raspberry Pi to your Dropbox account. Since you need you copy/paste some links to your browser it helps enormously to perform this part on a PC while connecting to your Raspberry Pi over SSH.

After you finished your Dropbox setup the 5th LED should blink three times telling you everything went well. Push the switch again to test if the script will now run without any user input. If it does go to your Dropbox folder and under Apps/<YourAppName> there should be 2 scans. Well done!

For the finishing touch go to /etc/ on your Raspberry Pi and edit the rc.local file (sudo nano rc.local). Just before the end (exit 0) add a line containing: sudo python scan.py & . This makes the scripts start up automatically on boot. Reboot your Pi and see if the System Ready LED comes up. If it does your in business and you’ve got your Raspberry Pi powered scan server with one-click-to-Dropbox capabilities.

That’s it for part 1 of this series. In part 2 I’ll be setting up the printer bit of the server. But I also got plenty of nice ideas I want to add to the scanner server. What would you think about:

  • web interface for scanning (advanced settings)
  • control scanner from your smartphone
  • scanning to PDF (with multi page support)
  • one button copy to printer

So watch this space. There’s lots more to come.

Inspiration for this project came from the following sources:

Android Game Consoles: Ouya vs GameStick

For a long time the big three (PlayStation, XBox and Wii) ruled the land of the game console. But last year a new console was announced: The Ouya. This Android based game console aims at independent game creators and casual gamers instead of competing with the big consoles. The only competition for the Ouya comes from the recently announced GameStick, another Android game platform. Let’s see which one looks the best on paper.

Limited edition of the Ouya game console

Ouya console

Both the Ouya and the GameStick run Android and come with a controller. And both are relatively cheap. But that’s about as much as these two consoles have in common. Yet they will be fighting for the same group of gamers.

Ouya

The Ouya is the more classic console of the two. It comes with the beautifully designed game console itself which is roughly the size of a Rubix cube and a Bluetooth controller. For 99 Dollar you get a Tegra-3 quad-core processor, 1 GB or RAM, 8 GB of storage and both Ethernet and WiFi.

In April of this year the Ouya should be officially released. But this Kickstarter backed project is right on schedule and the development units already started shipping in December last year.

GameStick

The GameStick is an Android based stick which is combined with a Bluetooth controller as well. The GameStick plugs into your TV directly with its HDMI connector which also acts as power source. This means it has no cables at all. When not in use the GameStick can be stored in a slot on the controller leaving you with a very small and portable package.

Game Stick and Controller

Game Stick docked in its Controller

At 79 US Dollar the GameStick is cheaper than the Ouya but you also get less powerful hardware. It is equipped with a dual core Amlogic 8726-MXS processor, 1 GB of RAM, 8 GB of storage and WiFi and Bluetooth. Just like the Ouya it runs Android Jelly Bean 4.1.

Though the GameStick team also aims for an April release so far only a prototype has been demonstrated. But since the GameStick is based mainly on existing hardware and devices it seems likely it will be released on schedule as well.

Hardware

Though the GameStick has the least raw muscle power it should still be able to play most of the newest Android games well. So far PlayJam has identified 200 games from the Google Play store which will run smoothly on the GameStick. The Ouya will have no trouble running any Android game you throw at it. So you won’t get stunning 3D gaming like on your pc but great games like Dead Trigger will run well.

A bigger concern I have with the GameStick is that in fact it is nothing more or less than an Android SmartTV stick with a fancy controller. Like the iMito MX1 I reviewed recently it might have the same WiFi issues and even not play surround sound over HDMI. We’ll have to wait until the final version arrives to make sure if it managed to avoid those pitfalls.

Portability

This is clearly the strong point of the GameStick. Ideally you can just pop the stick into the controller and take it with you to play at a friends place. This will only work if your friend has got a TV that supports power over HDMI. Otherwise you’ll still be carrying around a power adapter.

XBMC

When a new mobile OS is launched the first question asked is: Does it play Angry Birds? Nowadays every new Android device also has to answer one crucial question: Will it run XBMC?

Both Android game consoles will get XBMC support and obviously turns them into great media center devices. Again my earlier concerns about the WiFi and sound could completely spoil your XBMC experience with the GameStick (just like with the iMito MX1).

Google Play

One big drawback of both devices is their lack Google Play support. That’s right. Both will most likely not get Google Play. This means you can’t use your already purchased games on these devices.

Also developers need to port their games and apps to the Ouya and GameStick game stores. Both teams have already name a list of development companies who will support them so there should be enough games available when the consoles are launched. But you can’t be sure all the latest and greatest Android games make it to your device.

The Verdict

Both devices are pretty interesting and hopefully the start of casual gaming on the big screen. It is way too soon to pick a winner and a lot depends on the actual look and feel of the two consoles. The controller of the Ouya looks more comfortable than the one that comes with the GameStick. But only a hands on test can prove if this is really the case.

At this moment my money is on the Ouya though. If you really want a portable device the GameStick might be appealing. Otherwise the better hardware, Ethernet port and stunning design of the Ouya make it the best choice at the moment and well worth spending the extra 20 dollars.

Another problem with the GameStick is the fact that it basically is an Android thumb drive that comes with a controller. Why not go for a MK802 or iMito MX1 which are already available? The hardware is identical and once rooted you can hook up a PS3 or XBOX controller. And unlike the GameStick these devices have full access to Google Play meaning you can play (almost) any Android game available.

Finally the amount and quality of available games will make or break these platforms. But since these are both Android consoles porting games should be easy so I expect all major developers to support both platforms. But lets hope we’ll also see some nice indie games coming to these console like the Ouya project intended.

Comments Are Working Again

Due to some technical problem it was impossible to comment on posts and pages. I already felt it was pretty quiet out there.

Things are fixed and you should be able to share your thoughts again. Sorry for any inconvenience caused by this issue.
