As you all may or may not know I’ve been tasked to clean up parts of the scraping process in my GSoC project. A first step to this is to gather some information so that we statistically can say what formats your media is formatted in: do you usually have dots instead of spaces, do most add year to the folder name of a movie, etc. Many of you might alter this to fit xbmc so we want to somehow catch those we do not handle so we can try and find some pattern in those formats as well!

To do this, we’ve created a script that you can find in the Program Addons folder of your XBMC install called “Statistics gathering for scraping GSoC 2012.” What the script will gather is the bare essential metadata if scanned into the library, title, year, runtime, tvshow, episode number and season number etc. The file path is also stored as it is what generates this data and of great importance to know, saying that I want to note that we will NOT store any username or password information in any part of these URLs, this script is not meant to track the users and it cannot track you! The data is uploaded to a server which we on the team can view and no data about your system except the metadata and file urls are uploaded, no binary data from the files of any kind!

Even with these assurances, we know that not everyone will be willing to send in that limited information, so we’ve made this addon “opt in.”  In order to participate in the study, you have to install the addon from the Program Addons folder in XBMC. I urge anyone, those displeased with how our scraper handles their media and those where it works perfectly, to install this addon if you want to help do your part to make XBMC even more awesome. The more information we have, the better our scrapers will be.

Once again, the addon is called “Statistics gathering for scraping GSoC 2012,” and it may be found in the Program Addons section.

Cheers, Tobias

Update: There’s a (known) bug in the current version of the addon which makes it fail on start. It will be fixed ASAP. We are sorry for the inconvenience.

Update 2: The bug has been fixed and the updated addon is now available from the official repository. Before you install it, make sure it’s version 0.0.4. If not you can either force refresh XBMC’s official repository (using the context menu) or wait a few hours until it happens automatically. Once again, we are sorry for the inconvenience.

Update 3: The server is brought down while I go through and backup the data. You all might be interested to know that you almost took down the server with all the data :) So thank you all so much, you have given me more than I ever hoped for! I will post updates ASAP!

I have been selected by the Beagleboard community and Google to work on Google Summer of Code 2010. My project will consist of optimizing the rendering of XBMC for the embedded market.

The Beagleboard is an arm based embedded device. Similar hardware can be found in the smart phone segment, for instance the first generation of Android based phones. The current version of the hardware will not be able to deliver 1080p but upcoming generations might. This opens up a wonderful possibility for XBMC.

The problem with XBMC is that it is just too heavy to render as is. Most of the time the interface sits close to static and while a user would perceive this as an idle state, XBMC is far from idle. Every frame the application renders the interface from the ground up and no matter if the interface is completely static this is done at 30-60 times a second! Because of this, the project will focus on moving to an event based rendering system. This will introduce a true idle state and will lower resource usage when the application is idle, however this in itself is not enough. Even if a window is static initially, a skinner can easily add non-static elements such as scrolling text or animated images, which means we again have to render at full frame rate. Thus lowering the actual rendering overhead is also necessary.

During the summer I will keep the community updated on this blog on a weekly basis. Since some of the content will be very technical it has been decided that only a part of the posts will be pushed to the front page of xbmc.org. If you are interested in getting all the updates regarding this project navigate to the full URL for my blog as it will contain the unfiltered posts as well. For those interesting in helping out I will be idling in both the standard XBMC and the beagle board IRC channels. I will be working in a branch in the normal XBMC svn (not created yet) but will be named gsoc-2010-beagleboard and anyone is free to check out the progress there.

I hope you have enjoyed this introduction and I will end by saying that this will be a great summer for the users of slower hardware and a grand summer for the possibility of a small, silent, affordable and low powered device capable of delivering the full XBMC experience!

Basically you choose the script ‘Aptitude‘ from the script section and it will download, install and configure your system. The magic of aptitude in Ubuntu is a wonderfull thing.
Even if most people that have used Ubuntu for a while might know what Im talking about but the newer users of XBMC Live might not be familiar with this.

Basically Aptitude is the packagemanager of the OS we use in XBMC Live, it can look like the Windows Update on a fast lookover but aptitude is so much more. It handles all applications and you never need to go out and hunt your applications latest versions of the installers. In aptitude you don´t even need to go out and install the different helper libraries you sometimes have to do with windows, ever needed to download dotNet?

Aptitude will download, install and configure this for you. It will even tell you when a new version is out! We haven´t had this feature in XBMC live and the users have been forced to drop to terminal to do this maintenence, even though its somewhat doable it is still not even close to the feeling of a home appliance.

For those of you that want to install the script its located in the xbmc-additions, but its not that easy to install as of yet.
Basically as aptitude needs root privileges you need to allow this script (install.py) to be executed without asking for password. Hopefully XBMC we will add support for a script to call down the password dialog and then we could ask for the password making this script super easy to install.
EDIT: This is now fixed and latest svn of the script can do this

When all the small issues are bug bashed (with help from users) this script will find its way into next XBMC Live release, and then users won´t need to think about how to install it.

Anyway, the days of having to kill PulseAudio is now gone! in SVN we have added full native support for PulseAudio, this works in both DVDPlayer and PAPlayer. This is also a runtime drop in replacement for ALSA so if PulseAudio crashed or got killed XBMC would fallback and use ALSA. We also added a gui notification when XBMC failed to open either ALSA or PulseAudio so the user this time knows that there actually was an error without hitting the log. So if you see this please check your audiosettings and if nothing seems wrong provide a log on the forum

A feature of PulseAudio is that it´s network transparent, and as such you can connect to a remote computer and have it play the audio. And of course we added this to XBMC, just create an advancedsettings.xml as this:

<advancedsettings>

<audio>

<audiohost>PulseAudio Server IP</audiohost>

</audio>

</advancedsettings>

And it should connect to the other computer.

Known issues:

• Navigational sounds is still dependent on SDL, export SDL_AUDIODRIVER=esd before entering XBMC might help.

XBMC.Shutdown() – Will trigger your default behaviour (setup in settings -> system)
XBMC.Quit() – Will quit XBMC
XBMC.Powerdown() – Will shutdown the system
XBMC.Suspend() – will suspend the system
XBMC.Hibernate() – Will hibernate the system

So all the skinners out there, now go and make your skins suspend and hibernate compatible!

disclaimer:

On Xbox the XBMC.Shutdown() is not choosable and will always powerdown the system.

On Xbox the XBMC.Quit() will do the same as XBMC.Dashboard() and both work the same throughout the plattforms.

On Xbox neither of XBMC.Suspend() and XBMC.Hibernate() will work due to hardware limitations, although they are perfectly safe to use (just won’t happen anything).

On the roadmap for atlantis+1 I will hopefully add XBMC.CanSuspend() XBMC.CanHibernate() and XBMC.CanPowerdown() so skinners don’t have to know which plattform can do what. Also to make it safe because it’s not a certain thing that all computer IRL can hibernate as it relies on HDD Space available.

In a nutshell the remote is doing querys to XBMC’s webserver and displays the result in a neat fashion, but if we skip the technical mumbo jumbo it controls XBMC in that very apple sort of way. Which is one of the things I especially liked about it, it looks more or less exactly like the iPod mode on the iPhone.
The remote downloads both thumbs and info from the library and displays them tailored for the current view, good job!

I especially love the TV Show view as it really makes use of the wide icons in such a good way!

Narcan has though about something more, at some point those views might not be enough at which point you just flip it upside down and you’ll get something that looks like an IR Remote, very thorough work indeed!

The Remote mode is very responsive and works very well. The only thing I miss from this view is the ‘home’ button, something a former MCE user might miss.

All in all this application is very well polished and easy to set up, I would recommend it!
