  • Fedora 28 Planning For VA-API 1.0 Support

    The latest work by Fedora developers on feature work for Fedora 28 is shipping with VA-API 1.0 support for updated capabilities around the Video Acceleration API.

    The VA-API 1.0.0 API/ABI is provided by the libva 2.0 video acceleration library. Libva 2.0 was released last October with H.264 FEI support in its API, deprecating older parts of the API, fixing a race condition with the Wayland support, renaming some parts of the API, improving the logging capabilities, and various other changes. Libva 2.0 broke API/ABI compatibility with older versions of this Intel-developed Video Acceleration API.

  • A crisis, the causes and a solution [Ed: LWN says "this blog posting from Leonardo Chiariglione, the founder and chair of MPEG, on how (in his view) the group is being destroyed by free codecs and patent trolls."]

    Because there are rumours spreading about a presumed “MPEG-Video collapse” and Brownian motion-like initiatives trying to remedy – in some cases by the very people who have contributed to creating the “crisis”.

    [...]

    In its 30 years of operation MPEG has created digital media standards that have enabled the birth and continue promoting the growth of digital media products, services and applications. Here are a few, out of close to 180 standards: MP3 for digital music (1992), MPEG-2 for digital television (1994), MPEG-4 Visual for video on internet (1998), MP4 file format for mobile handsets (2001), AVC for reduced bitrate video (2003), DASH for internet streaming (2013), MMT for IP broadcasting (2013) and more. In other words, MPEG standards have had and keep on having an impact on the lives of billions of people.

    [...]

    In 2013 MPEG approved the HEVC standard which provides the same quality as AVC at half the bitrate. The licensing situation is depicted by the picture below (courtesy of Jonathan Samuelsson of Divideon): there are 3 patent pools, one of which has not published their licence and a significant number of patent holders that have not joined any pool (and not published their licences either).

     I saw the threat coming and one year ago I tried to bring the matter to the attention of the higher layers in ISO. My attempts were thwarted by a handful of NPEs.

    Alliance for Open Media (AOM) has occupied the void created by MPEG’s outdated video compression standard (AVC), absence of competitive Options 1 standards (IVC) and unusable modern standard (HEVC). AOM’s AV1 codec, due to be released soon, is claimed to perform better than HEVC and will be offered royalty free.

    [...]

    The work of patent pools would be greatly simplified because they could define profiles with technologies that are “available” because they would know who owns which tools. Users could switch on tools once they become usable, e.g. because the relevant owner has joined a patent pool.

    These are just examples of how the MPEG standard development process can be adapted to better match the needs of entities developing licences and without becoming part – God forbid – of a licence definition process.

    [...]

    Companies will slash their video compression technology investments, thousands of jobs will go and millions of USD of funding to universities will be cut. A successful “access technology at no cost” model will spread to other fields.

    So don’t expect that in the future you will see the progress in video compression technology that we have seen in the past 30 years.

GNOME Desktop: Flatpak and Random Wallpaper Gnome Extension

  • Flatpak in detail, part 2
    The first post in this series looked at runtimes and extensions. Here, we’ll look at how flatpak keeps the applications and runtimes on your system organized, with installations, repositories, branches, commits and deployments.
  • Flatpak – a history
    I’ve been working on Flatpak for almost 4 years now, and 1.0 is getting closer. I think it might be interesting at this point to take a retrospective look at the history of Flatpak.
  • Random Wallpaper Gnome Extension Changes Your Desktop Background With Images From Various Online Sources
    Random Wallpaper is an extension for Gnome Shell that can automatically fetch wallpapers from a multitude of online sources and set it as your desktop background. The automatic wallpaper changer comes with built-in support for downloading wallpapers from unsplash.com, desktopper.co, wallhaven.cc, as well as support for basic JSON APIs or files. The JSON support is in fact my favorite feature in Random Wallpaper. That's because thanks to it and the examples available on the Random Wallpaper GitHub Wiki, one can easily add Chromecast Images, NASA Picture of the day, Bing Picture of the day, and Google Earth View (Google Earth photos from a selection of around 1500 curated locations) as image sources.

KDE: QtPad, Celebrating 10 Years with KDE, GSoC 2018

  • QtPad - Modern Customizable Sticky Note App for Linux
    In this article, we'll focus on how to install and use QtPad on Ubuntu 18.04. Qtpad is a unique and highly customizable sticky note application written in Qt5 and Python3 tailored for Unix systems.
  • Celebrating 10 Years with KDE
    Of course I am using KDE software much longer. My first Linux distribution, SuSE 6.2 (the precursor to openSUSE), came with KDE 1.1.1 and was already released 19 years ago. But this post is not celebrating the years I am using KDE software. Exactly ten years ago, dear Albert committed my first contribution to KDE. A simple patch for a problem that looked obvious to fix, but waiting for someone to actually do the work. Not really understanding the consequences, it marks the start of my journey within the amazing KDE community.
  • GSoC 2018 – Coding Period (May 28th to June 18th): First Evaluation and Progress with LVM VG
    I got some problems during the last weeks of Google Summer of Code which made me deal with some challenges. One of these challenges was caused by a HD physical problem. I haven’t made a backup of some work and had to rework again in some parts of my code. As I already knew how to proceed, it was faster than the first time. I had to understand how the device loading process is made in Calamares to load a preview of the new LVM VG during its creation in Partition Page. I need to list it as a new storage device in this page and deal with the revert process. I’ve implemented some basic fixes and tried to improve it.

Open Hardware: Good for Your Brand, Good for Your Bottom Line

Chip makers are starting to catch on to the advantages of open, however. SiFive has released an entirely open RISC-V development board. Its campaign on the Crowd Supply crowd-funding website very quickly raised more than $140,000 USD. The board itself is hailed as a game-changer in the world of hardware. Developments like these will ensure that it won't be long before the hardware equivalent of LEGO's bricks will soon be as open as the designs built using them. Read more
