Notes:

I participate in the GNOME project as an editor and news-hunter for Gnomedesktop and the GNOME Summaries. I also maintain the gnome-themes-extras package and try to help out with getting the SVG support in GNOME as good as possible. Last but not least I contribute to the GStreamer project.
I work at Linux Multimedia Specialist Fluendo as their business manager.

GStreamer, Google, San Fransisco and being stuck

Currently staying at my friends David Schleefs place in San Francisco. Davids company Entropy Wave is about to launch some rather cool new hardware encoders rack boxes, which David showed of during the CE Linux showcase. The boxes will support both Theora and H264 encoding to enable the easy creation of HTML5 friendly content. People where also quite impressed by Davids DSP port of Theora for Texas Instruments OMAP3 which was sponsored by the Mozilla Foundation, there was also some interest by other chipset vendors to get David to also port it to their architectures which could be a great development in terms of Theora based HTML5 support on mobile and embedded devices.

I was here to attend the CE Linux and Linux Foundation Collaboration Summit conferences this week and its been interesting. Btw, thanks to Google for the Nexus One phone, will be interesting to get home and do a throughout comparison with my Nokia N900. One thing I already discovered doing some prelimenary testing is that the Nexus One doesn’t seem to support syncing contacts over bluetooth, so its a bit of a cumbersome process it seems to move my address book onto the Nexus One from the N900. Talking of Google, the most repeated rumour, from a lot of people at the conference all claiming inside sources at Google, is that Google is about to open source the VP8 codec, using it both for Google Talk video conferencing, for HTML5 in Android and Chrome, and for You Tube. Will be interesting to see if this happens though and under what terms in the end. And if it happens it will be equally interesting to see if the quality of the encoder is good. Heard some claims that the current VP8 encoder actually creates worse quality videos than the latest Theora encoder at the same bitrate, which would make Googles refusal to support Theora for HTML5 for Youtube a bit sad.

Got to talk to quite a bit of people using GStreamer on their products, and I based on those conversations I can easily foresee that we will be getting more contracts in the future, at Collabora Multimedia, which task is basically mainlining vendor patches for things like GStreamer and Pulse Audio from vendors who are using these libraries in their products. While most companies wanted to see their patches go upstream to avoid eternal pains of maintaining and re-applying their modifications, they seem to have trouble allocating staff needed to make it happen. So hiring specialists like us to do the needed patch clean-ups and get them ready to be merged is easier to fit into their timetables and budget. Tim Bird, the chairman of the CE Linux forum, actually mentioned in one of his talks that this was the method that a lot of their members have found to be most cost effective in terms of getting patches upstream to a lot of different projects, hiring core contributors to the project in question as consultants to take the patches to a stage where they can be merged.

Last night I attended a GNOME dinner hosted by Adam Dingle of Yorba.org fame, seems Yorba is making good progress on their projects, with Shotwell their photo manager, getting included in next version of Fedora. A big thanks to Adam for setting up this dinner, much appreciated.

The other thing that I am wondering about at this point is whether I will actually be able to fly back to the UK on Sunday. With the volcanic ash messing up everything I am starting to worry a bit. Seems BA though is re-routing their US flights to Glasgow and then providing buses to take people down to London. Not to excited about the prospect of a 6.5 hour bus ride though, but I guess considering the circumstances I shouldn’t complain. And if I do end up getting stuck here then there are not a lot of places in the world I would choose over San Francisco to be stuck, it is an really great city. However since getting stuck in San Francisco would also mean a delay in seeing the most wonderful woman in the world again, I am not in a good position to enjoy having my stay in San Francisco extended.

Anyway, no use in worrying about my flight until Sunday, in the meantime I am looking forward to Mike Smiths birthday party tomorrow, especially since Mike is taking the step of joining me in the 30+ old geezer club.

Google Summer of Code deadline

Just thought I remind everyone that the deadline for submitting a Google Summer of Code proposal is tomorrow. So if you want to do a GStreamer or any other SoC project this year you need to get your proposal submitted ASAP.

Student application period for Google Summer of code opens

Thought I should remind everyone that starting from today one can submit proposals for the Google Summer of Code. So if you are a student and interested in doing a GStreamer SoC project (or one of those obscure other projects participating for that matter :) this summer then be sure to get your proposal inn.

GStreamer and Google Summer of Code 2010

So a big thank you to Leslie and her team at Google for also this year accepting GStreamer as a mentoring organisation. Last few years we had some great projects coming out of the Google Summer of Code, including MPEG PS muxing, Quicktime Muxing, ASF muxing, LADSPA version 2, Avisynth, MHEG support and more.

If you are a student and want to get some useful experience while getting paid this summer, developing multimedia software, I think there is no better way to do so than a GStreamer GSoC project, for instance you could help us develop our first native VAAPI elements or any of the other tasks on our SoC project suggestion list.

Of course don’t limit yourself to that list, personally for instance I would love to see some proposals from students interested in extending PiTiVi.
With it being shipped with Ubuntu now and transition support getting merged very soon it is a great time to help userfriendly video editing on linux become a reality. Just be sure to keep it stable as you add your features though as we don’t want join the other efforts out there in the click and crash category ;)

Interested students should check out the Google Summer of code website for details on how the project works and how to sign up.

Please feel free to ask questions on the GStreamer-devel mailing list or on the #gstreamer channel on irc.freenode.net.

Latest Dirac (schrodinger) release is really fast

I thought I should let people know that they really should grab latest version of the Schrodinger encoder/decoder from diracvideo.org. If you saw David Schleefs blogpost about Dirac you would have seen him mentioning it is much faster.

Having tested with GStreamer I can confirm that it is the case, it is really fast now, and CPU usage which used to be the achilles heal of Dirac doesn’t seem to be an issue now. Be sure to also grab gst-plugins-base 0.10.28 too though, as it contains a critical fix for playing back Dirac in Ogg containers.
