Ubuntu Disapointment

One thing I ranted about multiple times in my blog over the years is how Linux distributions have failed to provide their content in Ogg format. Especially when the content is targeted at Linux users it suprise me that they do not make sure to have the video available in the format that basically all linux users have support for out of the box. That said both Red Hat and Novell has actually taken this feedback to heart and more often than not they do provide Ogg videos these days (in addition to various other formats).

It saddens me then when I checked out the link in Jono Bacons latest blog entry. Where the Ubuntu MOTU videos seems only to be available in the proprietary Flash format. For a distribution which likes to drape itself so loudly in the colours of community and freedom this is a huge letdown. And while you can view these videos with things like swfdec you still need to have the patent encumbered codecs available through gst-ffmpeg to actually view the videos. Would it be so hard to also offer those videos as a Ogg Theora torrents for instance?

Update: Talked to Jono. Turns out they do plan on making Ogg’s available, but haven’t gotten around to it yet. While I kicked Ubuntu here, it wasn’t really about them specifically, but the fact that even though the tools have gotten quite good and widespread over the last few years in terms of creating Ogg’s the open source or free software community is still rather lackluster in its willingness to try to help push the free formats. Its kinda how I used PNG images on my website even before there was widespread PNG support, cause if my page got just one person (hi mom) to use a PNG supporting browser it was a step forward.

Jokosher fixes inbound

As I mentioned in my blog entry about Sebastian Dröge joining Collabora he would among other things work on some low level GStreamer issues which has held Jokosher back. Thanks to Sebastian working on improving the GStreamer audioconvert and deinterlave elements things are now looking very good for Jokosher, a big thanks to Peteris Krisjanis of the Jokosher community for testing the fixes so quickly for us. I have now even challenged Jono and Stuart about recording a LUGRadio episode using Jokosher as that was in some sense the original reason for Jokosher being created so I feel it would be a good milestone on progress :)

Sebastian still has some work on the interleave element left before he will switch over to focusing on some improvements for Pitivi mostly improving our Matroska and MPEG support.

Personal life

Starting to settle pretty good into Cambridge life I think.  My ongoing golf lessons are starting to pay off and I can now go to the driving range and feel pretty happy at what I do there. Not to claim I am at a useful level yet, but at least some of the basics are starting to fall into place. I also finally got myself moving on starting up a second activity, in addition to the golf,  so I had my second riding lesson this morning.  I am so far enjoying the riding quite a lot, apart from the dorky looking helmet and the new boots giving me blisters. Still working on finding a good timeslot for the riding though, seems the horses do not enjoy an early morning as much as my golf instructor.

The Cambridge Beer Festival is currently underway and yesterday I got to try the cutely named Norwegian Blue. Not named after the country with the fjords as much as after a parrot in a Monty Python clip :)

We are heading back there this evening with Michael Meeks joining us for some further beer sampling, travelling from the distant planet of Newmarket. We tried getting Edward Hervey also to join us, as he is actually in London currently, valiantly helping one of our customers, but even the famous beer festival cheese selection was enough to lure him away from his task :)

Heading up to Norway tomorrow evening for a long weekend in conjunction with my cousins daughters confirmation. I tried to get her to take a valiant stance for atheism instead, but the lure of presents and a big party strangely enough won out :) Its also my mothers birthday early next week and while I normally do not travel up to Norway I felt it was the right thing to do this year considering my mothers recent brain surgery with the (small) stroke that caused.

Sebastian Dröge joins Collabora Multimedia

Thought I should let the world now we have a new employee at Collabora Multimedia. I think most of you know him already as Sebastian Dröge is one of the biggest patch reviews and bug fixers in the GStreamer community already. While Sebastian will be helping out with some of our internal projects we also plan on letting Sebastian continue his great community work. In fact the first assignment we have given him is simply to try to help out with some hard bugs thats been troubling Jokosher for a long time. So a big welcome to Collabora Sebastian, and an especially big thanks for starting your new job by taking GStreamer once again out of the top 10 bugzilla list :)

Sun’s new video codec

So Sun Microsystems video codec effort is now public. Actually its been public since the 11th of April, but I missed it until today. I think it is an interesting effort and wish them good luck. That said I noticed from the comments that people where wondering why they where not instead pushing Theora or Dirac forward instead of making their own codec. Well the answer to that question is implicitly given in Rob Glidden’s blog post, Sun wanted something which they felt was 100% sure to not be under any current patents and thus they started with the sure to be patent free H261 codec (due to its age).

Of course that is similar to the approach the BBC took with Dirac, but instead of using an codec implementation they used old text books and research papers as their baseline.

That said neither the OMS video codec or Dirac can be 100% sure that there will never be any patent lawsuits, to many bogus patents for that. So all they can do is what they have been doing, which is to ensure that their prior art story is so strong that if a case ever is brought they should be able relatively easily defeat it.

And while I would of course love even more people contributing to improving out existing codecs like Theora and Dirac and think that getting new codecs launched which has used different strategies for ensuring their royalty free status is only a good thing as it gives us more angles of attack. And once one of these codecs reaches critical mass in terms of consumer adoption I think it can actually open the door to the others as it will reduce the current ‘stigma’ around royalty free codecs.

In the meantime we just need to continue improving our tools as I feel that is the next step we need to take to help push free codecs forward. My goal is that we will get Pitivi and Jokosher to a stage where we have them running on all three major platforms and thus the threshold for getting your marketing department etc., to publish their audio clips and videos with free codecs is greatly reduced. The two Summer of Code students we have working on Pitivi and the renewed Jokosher effort should help push us forward.
I am also hoping that the codec support provided in HTML5 through Firefox will open some doors. While Apple and Microsoft are still trying to sabotage it there is still hope that the market share of Firefox is large enough to make a difference and force the issue.

Fedora 9 looking good

I upgraded my laptop to the latest Fedora Core 9 test release last night due to having some issues with a broken keyring database. And I have to say it is a very nice experience so far. The major thing I think a lot more people than me has been waiting for is having the GNOME keyring database connected to your gdm login. So now more first login in then providing they keyring manager your password before it logs you onto the wireless or email servers.

Another small bug now fixed is that when you boot with for instance a SD card in the machine it pops up on the desktop right away. in FC8 I had to take it out and put it in again once the desktop was running to get it automounted.

The system monitor is also become very nice, while this is a GNOME improvement more than something Fedora specific it is still something I appreciated when I took at look at it. There are also some improved icons, especially the new SD card icon looks really sweet.

Various bits of polish added to NetworkManager also like a Connection Information item. The power manager has also improved, and it now asked me if I wanted to change my lid down action when connected with mains power to avoid system risking overheating.

Firefox 3 is of course another nice improvement of this release. And it seems Fedora integrated the OpenOffice GStreamer patches created by Novell as I was able to put an Ogg video into a presentation and have it work now.

I also liked the fact that when I had to type in my SSH password in a terminal window the gnome-keyring popped up a dialogue asking if I wanted it to remember this password, very sweet indeed.

Only thing I am not to fond of is the new GDM log in, it feels slow and cumbersome as I first have to pick my name from the list before it ‘slowly’ brings up the password field.

More SoC Pitivi hacking

So it turns out we got 2 Summer of Code projects working on improving the Pitivi non-linear video editor. Sarath Lakshman will be hacking on Pitivi this summer as part of the Fedora Summer of Code. This is in addition to the work that Brandon Lewis will be doing. So hopefully by the end of summer Pitivi will be useful for a lot more people.

Biofuels, how long before the stupidity ends

I always believed that good environmental policies are crucial to the future of this planet, but for every year that goes by my faith in humanity’s ability to enact useful ones diminish. Partly because I think the main environmental issue is human overpopulation and unfortunately faith based organizations have sabotaged every UN attempt at pushing for some global policies and debates on that.

The other thing is that politicians seems unable to react in an intelligent way when faced with new data. And I am not just talking about the American right holding their hands over their ears screaming lalala for many years instead of facing the facts that global warming was real. Or arguments that science will be able to overcome any problems eventually so there is no need for hard hitting policies, the last argument strikes me as the same as encouraging unprotected sex with HIV positive people since science will probably come up with a cure before you die from Aids. While I am a strong believer in what science can accomplish you have to make your plans on what is currently available, not on what you hope is going to happen.

One of my favourite examples of political stupidity from Norway is milk carton recycling. You see, for many years the government did huge campaigns to try to get people to send in their milk cartons for recycling, most of these campaigns especially targeted towards children. Then some years ago a researcher pointed out that recycling these cartons was actually less environmentally friendly than just burning them. The pollution caused by transporting them in for recycling combined with the chemicals they had to use to dissolve the wax protection on the cardboard was a bigger environmental hazard than actually just burning the cartons at the local garbage treatment plants. So what did the government representative say when faced with this? Did the representative say that with this new information the recycling project would be stopped? No, instead the representative managed to say that since stopping the recycling project might undermine the faith in the environmental policies and due to the great symbol value of the project for environmental protection it would continue…… Yep, nothing strengthens policy support and provides greater symbol value than doing something stupid.

These days we are faced we what has turned out to be a similar stupidity on a global scale. Biofuels.

Biofuels has been hailed as a white knight for both energy problems and environmental policies, but recent research has shown that it actually might be a environmental disaster, not to mention its contribution to the rising prices of food will also make it a participant in a humanitarian disaster.

The problem with biofuels is that while the plants involved do photosynthesis like any other plant they do less than a similarly sized field of wild plants and trees. And since current biofuel policies are causing a lot more forest and wild fields to be turned into farmland for biofuels, the amount of CO2 converted to Oxygen lessen. And voila, the push for biofuels manage to accelerate global warming instead of slowing it. Question if how many years it will take for politicians to catch on to this and for instance the EU biofuel goal to get scrapped.

Summer of Code Projects

GStreamer

Seems the slot count for Summer of Code is now as close to set in stone as it will be so I guess its time to announce the four projects that got approved as part of the GStreamer SoC.

First our we got Thiago Sousa Santos who will be writing a mp4/qt/3gpp muxer for GStreamer. This will fill a big hole in our current lineup of muxers. This project will be mentored by Wim Taymans.

Then we got  Brandon Lewis working on Pitivi. He will among other things be adding still image and transitions support to Pitivi. This project is mentored by Edward Hervey.

The third project is Richard Ronald Spiers working on MSN support in Farsight2. This means that any Farsight2 using application will be able to communicate with MSN users. This project is mentored by Olivier Crête.

And last but not least is Roberto Fagá Jr who will be working on a video transcoder using GStreamer. Another critical project as it will help us keep our muxers and encoders well tested and working. This project will be mentored by Stefan Kost.

Dirac

The Dirac project ended up with two projects in this years Summer of code. Matthias Bolte will be working on OpenGL acceleration for Dirac and  Bart Wiegmans will be working on a Java implementation of Dirac. Both projects to be mentored by David Schleef.

GNOME

As every year a ton of GNOME projects got approved. Of special interest to the GStreamer community is the DVB Manager to be done by Sebastian Pölsterl, the Cheese OpenGL effects by Filippo Argiolas, Empathy bases IRC client by William Christopher Farrington, speech recording for tomboy notes by Gabriel Geraldo França Marcondes and Corvalan Cornejo Gabriel working on Empathy VoIP support.

Last day in the US

Currently sitting at the X Developers Summit at the Googleplex waiting for some time to pass before getting on the airplane this evening. X Development isn’t exactly what interests me mostly, but there has been some movements in terms of thinking about multimedia support issues. David Schleef did a talk here yesterday where he talked about colour handling. For a lot of Linux users, especially in the content creation industry, the lack of good colourspace correction support is a big issue.

Earlier this week I was at the CE Linux Forum meeting doing a talk about GStreamer. Talk ended up taking quite a lot less time than what I had expected it would, but still got a lot of nice feedback on it afterwards.

Bought myself one of these noise reduction headsets while here, so I am looking forward to testing out how well they actually work on my flight back to the UK.

Only thing I wish now is that I could blog about the two little ‘secret’ GStreamer projects that Edward and David Schleef are working on :)

Norwegian Public administration suddenly a lot more stupid

I learned today that that the Norwegian Equality and Discrimination Ombudsman have decided that public sector workplaces can not pay two groups with the same length of education differently. The specific case where a case where some nurses and some engineers in a small Norwegian community where earning different salaries, even though both groups had four years of higher education.

While the case will be taken to the courts, and hopefully overturned, it is an example of equality thinking having gone horribly wrong. There is so many problems with this decision that I have problems knowing where to start. First of all this decision forgets that the labour market, is in fact a market. Different salary levels come about as a result of supply and demand issues or a range of years. And if this rule is not overturned it means that public sector work places will basically be unable to get qualified employees in high competition parts of the labour market, as it is of course infeasible to increase the salary of every employee in the public sector each time one need to pay more for in demand labour.

The second part is that it makes the already ineffective tuning of the education sector to the needs of the labour market even more ineffective. If you can’t pay people who have been taking math in Uni higher for instance than someone studying other subjects, that means you have very few incentives for driving people towards harder and/or less popular studies which are needed for society to prosper.

If the rule stands it also plays into the already growing problem of education padding, where groups are continuously pushing for longer education periods to increase the standing of their profession. The financial education I took over four years is today actually a five year degree, and even when I did my degree I wondered to myself what knowledge or skill was actually passed to me during those four years which couldn’t been just as effectively transfered over three years.

The Norwegian socialists (communists?) need to wake up and realize that equal pay for equal work is not the same as equal pay for all work. Salary equality need to be aimed for on a macrolevel, not across random professional boundaries and organizations.The government is supposed to be involved in nation building here, not a re-enactment of Animal Farm.

And I am not saying that salary inquality is not something which cant be a problem. I do agree that policies aiming at making sure that women who holds basically the same job as a man should get on average equal pay is correct for instance. (And I repeat that the goal should be to look at that problem in the context of macro level averages as there are of course many cases where paying one person more than another is reasonable, even if they have similar backgrounds. An obvious example here is the world of pro-sports, but that applies just as much to other types of work, ie. Linus Torvalds is of course not comparable with any random person who spent the same amount of years as he doing computer science in Uni.)

And I was also musing while watching the US news and discussion shows on TV here yesterday, that
maybe one of the big issues undermining the US economy and sense of social unity is the enormous gaps in income here. But just like the gender equality issue trying to address that issues through public policy needs to happen gradually on a macro level and not on a micro level. For example are there laws or policies that could be put in place that would strengthen the bargaining position of those earning less and thus over time improve their average income level in relation to the rest of society?

Of course politicians today do not think in such high level terms, instead they prefer buying votes by earmarking money to specific groups.
