  • New Sanyo cameras have editing in mind

    13 octobre 2009

    Sanyo has announced some ’A’ revisions to their existing FH1 and HD2000 cameras, which add a new "iFrame" mode. It appears this is an i-frame only h264 mode, at a reduced 960x540 resolution. It’s a very interesting idea - if other manufacturers adopted it as an optional setting, and if NLE manufacturers supported it, it could turn H264 into an edit-friendly format. Right now, editing H264 is hamstrung by the extremely long GOPs and complex interframe relationships. Going to i-frame only makes it essentially a more advanced version of a codec like DV or DVCProHD.

    Interestingly, the bottom of the press release mentions that

    "The iFrame logo and the iFrame symbol are trademarks of Apple Inc."

    That’s news to me. One wonders if Sanyo jumped the gun on a release, or if this is just a format that Apple uses internally in tools like iMovie, which Sanyo has co-opted. I’ll certainly be keeping my eyes open for an Apple announcement about "iFrame."

  • Revision 21a0dade42 : vp8 : Modify to use closest reference in zero_mv bias. Modify zero_mv bias condi

    14 août 2014, par Marco

    Changed Paths :
     Modify /vp8/encoder/onyx_if.c


     Modify /vp8/encoder/onyx_int.h


     Modify /vp8/encoder/pickinter.c



    vp8 : Modify to use closest reference in zero_mv bias.

    Modify zero_mv bias condition to include check that "closest" reference is
    last_frame.
    This is needed for temporal layers, where the last_frame is not always the
    closest reference.
    Also, constain zeromv_count to be for last_frame reference.

  • Catalyst Open Source Academy

    16 janvier 2015, par Matthieu Aubry — Community

    The Open Source Academy is an initiative designed to provide training and work experience for young New Zealand technologists. Catalyst organises the Academy to show young technologists how to participate in open source communities and to fully explore their passion for IT through freely available open source tools.

    It has been running annually since 2011. We are proud that Piwik project could participate in the Academy again this year !

    What students got done

    It’s amazing what a few young students can get done in four days of participating in an open source project like Piwik ! They were able to quickly get started with Piwik, and continued to make useful contributions to the Piwik analytics platform.

    New Darkness theme

    Liam has created a new dark theme for Piwik called Darkness.

    Darkness theme

    To create the theme, Liam had to improve Piwik core stylesheets and created this pull request : Reuse the LESS variable for white color across all stylesheets.

    Accessibility improvements

    We were lucky to spend time with Julius, a Catalyst employee who is blind. He showed us in great detail how difficult and time consuming it can be for a blind user to use Piwik. For example we noticed how complicated it was for Julius to navigate the menus, to get to the main content, and to use the calendar and the Website selector. During this presentation we also noticed that Piwik was not yet usable with the keyboard.

    As a result of this session with Julius we got to work with the students to improve accessibility in Piwik.

    List of accessibility improvements

    All these pull requests were created by the students and have been successfully merged into Piwik :

    Summary

    Working with young students was fun and interesting. We were excited to see how much they got done in such a short time !

    At Piwik and Piwik PRO we are committed to building the best open analytics platform, and we will continue to support students who want to take part in the Piwik adventure.

    Be well,
