Media Explorer

Thursday, June 16th, 2011

Discovered a new piece of software using GStreamer the other day called Media Explorer. It is a nice media center type solution for the desktop and Meego devices. The system has been developed by mostly Intel engineers, but they have now made it freely available. I tried it on my Fedora system last evening and it seems to have a bit of a MeeGo bias currently, as it complained about Connman being installed and also didn’t look for media in the desktop Media directories, but I am sure those are smaller issues that can quickly be sorted out. Thomas Wood did this nice blog entry about it a couple of weeks ago, with some more details.

Anyway if you are looking for a linux based media center UI this might be what you are looking for, personally I will try to see if I can get it going on my little Panda board at home.

Update: Also noticed there is a nice article about Media Explorer on linux.com.

On the path to GStreamer 1.0

Tuesday, June 14th, 2011

GStreamer maintainer and code god Wim Taymans just posted an update on the the progress of GStreamer 0.11 to the GStreamer development mailing list. For those interested in learning about the new features coming in GStreamer 1.0 this email (along with the previous update) is must read material.

In addition to the updates on the core coding work and important notice from Wim in his email is that the very first 0.11.x release will happen this week, so that you have a snapshot release to start playing with. GStreamer 1.0 is moving forward at a fast pace, so be prepared :)

Hopefully we can do a GStreamer 1.0 release part at the GStreamer Conference 2011!

New GStreamer backend for Phonon

Wednesday, June 8th, 2011

Came accross this blog entry by Trever Fischer about his progress with updating the GStreamer backend for Phonon. Switching to using playbin2 has cut the codesize in half and added gapless playback support. Along with the availability of QtGStreamer this should improve KDE and GStreamer interaction a lot. Nice stuff!

GStreamer Conference 2011 update

Wednesday, June 8th, 2011

Just sent out this little email with some updates on the GStreamer 2011 Conference. Planning is progressing and a sponsorship leaflet is now available for those interested in sponsoring the conference. The call for paper deadline is also slowly but surely approaching, so anyone who wants to do a talk please send in an abstract before the 1st of July this year.

For everyone else, just register for the conference and set aside October for GStreamer and Prague :) As always details can be found on the GStreamer Conference 2011 website.

Luis talk on Rygel

Tuesday, June 7th, 2011

For those who don’t know yet Rygel is an open source implementation of DLNA, a standard for ensuring interoperability between the different media devices on your home LAN. Rygel was started some years ago by my friend Zeeshan Ali and is being used in Meego and GNOME among others. We have been working on Rygel for some time now and thus Collaboras own Luis de Bethencourt did a talk at the recent Meego Summit in San Fransisco. It is an interesting talk about the current state of Rygel and how a lot of the Rygel features are implemented using GStreamer. So if you are interested in the future of interoperable devices check out Luis talk at the Meego website. Seek about 3.5 minute into the talk as they haven’t edited the videos it seems so you get a lot of uninteresting preparation before the talk starts.

New PiTiVi release getting a lot of positive attention

Tuesday, June 7th, 2011

I am really happy to see how the new 0.14 version of PiTiVi is garnering so much positive attention. A lot of tweets seen and quite a few people blogging about this recent release, like this entry on omgUbuntu or this entry on Ubuntu corner or this little blurb on Phoronix.

A lot of people here at Collabora are involved with PiTiVi development as time allows and while we for a long while felt that we had a forest of features we could enable in PiTiVi, we seemed to be stuck with a certain feature set for a long while, as we kept going back to maturing the under laying GStreamer plugins and features that we wanted for PiTiVi. I think we have rounded a corner and with a total of 4 Google Summer of Code projects underway around PiTiVi we should be ensured that PiTiVi continues to develop quickly, as the PiTiVi team continue to both stabilize the current feature set and add new ones.
My hope is that PiTiVi will soon be packaged by every major distribution and be seen as a core part of the linux desktop and something that everyone uses when they need to edit their holiday movies or make small projects for school or work.

Hmm, remdinds me need to make sure we got a nice PiTiVi talk at the GStreamer Conference this year :)

Btw, for those interested in getting involved with PiTiVi, the best place to meet the community and get involved in joining the #pitivi channel on irc.freenode.net.

OpenOffice vs LibreOffice – the next chapter

Thursday, June 2nd, 2011

Been seeing with interest the latest moves around Open Office. While a lot of people see it as almost a direct attack on Libre Office, to me personally it seems like a clumsy result of Oracle trying to ditch OpenOffice without frustrating their main OpenOffice business partner, IBM. Due to having the Lotus Symphony suite based on OpenOffice under a special license from Sun/Oracle, I wouldn’t be surprised if switching to the pure LGPL Libre Office seemed painful to them. And thus the idea of an Apache licensed OpenOffice must have seemed endearing.

Personally I hope people stick with LibreOffice and build upon their existing success. Chasing a big company like IBM might seem tempting, but big companies change their mind and change priorities all the time, just look at Nokia, so if you have something viable without a big company involved, stick with it, and let the big company contribute on your terms if they want, as it will then have the ability to stay around even when the big company goes elsewhere.

GNOME 3 and Fedora 15

Wednesday, May 25th, 2011

Updated my own and my wifes computers yesterday to latest Fedora version, which included an upgrade to GNOME 3. Have to say I am quite impressed with it so far, I mean it is definitely a .0 release with a lot of little issues (like not remembering how to deal with my dual screen setup at work). But apart from that it feels pretty sweet, especially like the messaging integration into the desktop. It still got quite a few issues though, but here at Collabora we now have Jonny Lamb and Guillame Desmottes helping out with trying to polish it up.

The biggest change I found that was that of the attitude of my wife, she went from “linux sucks, why do I have to use this stuff” to “this is actually quite cool”.

So a big congrats to the GNOME 3 team for a wonderful release! I am looking forward to seeing how it develops in the coming Months.

I am generally impressed by all the nice work being done across a lot of projects these days, helping to make sure we have a really powerful and nicely integrated platform. It wasn’t that long ago the linux desktop (and server for that matter) felt like a taped together collection of stuff, but for each new release it seems the ease of use and polish increase, with good integration happening between all major layers. Efforts to drain the swamp, like systemd, does make a huge difference over time and draws us ever closer to the goal set when GNOME 2 was being created, remove the need to have configure options in the user interface to make the system ‘work’. If you need to enter a configuration menu to have basic functionality work, then that is a bug, not a feature.

I think there has been a general change in philosophy happening over the last 5-6 years, where we moved from everyone trying to fix the world in their own corner, to people instead trying to work together. For instance in GStreamer we have moved from trying to fix the problem by supporting every sound system under the sun, and instead try to work closely with the best solution out there to actually solve the problems people have, which is why people like GStreamer maintainer Wim Taymans have also been contributing to Pulse Audio over the last year. Enabling people to switch backends between ALSA, OSS, Sun Audio or Pulse Audio isn’t a solution, is it exposing a bug. So while the plugins supporting all those systems are still there of course, as they are useful for people in various situations, I think our thinking now is that when we find an issue that is best solved in Pulse Audio, as opposed to GStreamer, we solve it in Pulse Audio, instead of trying to make a second rate solution in GStreamer itself. And if there is a feature missing in Pulse Audio the solution is not to add an option in the user interface to ALSA, it is to add the feature to Pulse Audio. There are of course still cases where we need to support multiple plugins offering the same functionality of course, codecs being the best example, but if we want to make the open source ecosystem better we need to all focus on making things work well without needing the user to reconfigure which libraries and backends they use for a given task.

Seeing all this other great efforts move forward to plug the remaining holes I am also happy to say that by the end of the year we should have GStreamer 1.0 out the door, Wim Taymans is putting the foundations together as we speak. It should provide a lot of great improvements to GStreamer, like good solutions for handling 3D video for instance, but also provide a lot of speed improvements which will be especially useful for embedded setups (allthough I haven’t met a desktop user so far who hates getting faster software either.)

GStreamer Conference 2011 website up

Wednesday, May 18th, 2011

The website announcing this years GStreamer Conference 2011 is up. I am really looking forward to this years event due to the great fun last years event in Cambridge was. This year we will host the conference in Prague in the Czech Republic, a city I long wanted to visit and now I finally got a great excuse to do so.

For those who missed out on last years conference I think it is safe to say it turned out to be a wonderful place to learn about latest developments in the GStreamer community and hear about some of the challenges and solutions being used when using GStreamer in various devices and projects. This year Wim Taymans will be able to present on all the progress being made on GStreamer 1.0 and let us all know how things are looking in terms of setting a final release date :)

I moved last years conference page to a new permanent GStreamer Conference 2010 site, I recommend checking out that site for links to videos of all of the talks last year if you are unsure about if the GStreamer Conference is for you. This year we are co-hosting with 3 other conferences, the Linux Kernel Summit, the Embedded Linux Conference Europe and finally LinuxCon Europe, so there should be something for everyone.

In the land of silly arguments

Thursday, September 25th, 2008

Seems Lennart started a bit of a debate with his Linux Sound layers blog post. Not all the reponses has been as enlightened though. For instance Aaron Segio managed to make me laugh with his argument for why Phonon was a good alternative for non-Qt applications:

“Phonon is also more than just an option for Qt apps: you’d be making a huge mistake not to use it. You see, Phonon gets you equal and native support on Windows and Mac as well without the user having to install, say, GStreamer..”

Really? Wow, I would never have thought that if you use something instead of the other you wouldn’t need the other…an absolutely brilliant deduction. While we are at it lets point out that if you install Firefox you do not need to install Opera, cause you already got a web browser!!

GStreamer is already used by cross platform applications such as Songbird and SyncTV. And Songbird is using the native codecs provided by DirectShow and Quicktime where available.

So in a celebration of self serving arguments: So if you just use GStreamer you get equal and native support on Windows and Mac as well without the user having to install, say, Phonon…
