    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • Premium Plugins now available on the Piwik Analytics Marketplace

    2 novembre 2016, par Piwik Core Team — Community, Press Releases

    We are super excited to announce the launch of three new premium plugins which are now available on the Piwik Marketplace : A/B Testing, Media Analytics, and Activity Log.

    All three plugins are easy to use and come with 100% data ownership, documentation, integration with Piwik, powerful data exports and no data limits.

    These first premium plugins and the new Marketplace capabilities have been designed and built with love by InnoCraft – the new company brought to you by the makers of Piwik.

    1. A/B Testing

    A/B Testing helps you grow your business by comparing different versions of your website or app to detect the most successful version that increases your sales, revenue, conversions, pageviews, and more.

    A/B tests are also known as experiments or split tests. In an A/B test you show two or more different variations to your users (visitors) and the variation that performs better wins. When a user enters the experiment, a variation will be randomly chosen and the user will see this variation for all subsequent visits. Piwik A/B testing uses advanced statistical analysis to detect which variation performs better for your conversion goals and success metrics. Even small tests can increase your sales and conversions massively !

    2. Media Analytics

    Do you have videos or audio on your website, or in an app ? Media Analytics gives you powerful insights into how your audience watches your videos and listens to your audio, to ultimately maximize your success.

    Learn all about your audience. Which media your users are playing, for how long, how often, and where they dropped off ? Where are your users located around the world ? Who your audience are and what did people do before and after watching a video or listening to audio ? Many of the reports are also available in Real time, so you can gain insights and react quickly.

    Learn more here :

    3. Activity log

    Keep an eye on everything that is happening on your Piwik platform with the Activity Log plugin.

    The activity log, also known as audit log or audit trail, improves your Piwik’s security and diagnostic by showing a chronological set of entries that provides documentary evidence of activities that happened in your Piwik. It allows Piwik Super Users to quickly review the actions performed by members of your organization or clients, and also lets every user review details of their own actions.

    Learn more in the Activity Log FAQ or see a list of all the features on the Marketplace : Activity Log plugin.

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec takes much longer. Basically, MediaCodec can't keep up with the stream, and displays the video in slow motion, getting slower and slower as time goes on. Going back to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg does.

    I was wondering if this was either : A) An issue with the way my server is encoding NAL units, or B) An issue with my Android client, specifically the way it is receiving and decoding NAL units.

    My encoding configuration with x264 is :

    x264_param_default_preset(&param,"ultrafast", "zerolatency:fastdecode");
    param.i_threads = 1;
    param.i_bframe = 1;
    param.i_width = image_width;
    param.i_height = image_height;
    param.i_fps_num = 60;
    param.i_fps_den = 1;
    param.i_keyint_max = 10;

    param.rc.i_rc_method = X264_RC_ABR;
    param.rc.i.bitrate = 6000;
    param.i_sps_id = 7;
    param.b_repeat_headers = 1;
    param.b_annexb = 0;

    My Android MediaCodec client is set up as follows :

    I receive each individual NAL unit on a separate Live 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs from this queue, and if there are none available, waits until there are.

    Some notes :

    What I generally see happen is the queue starts filling up with NALs, instead of staying close to empty. So, I know that the decoder thread is not working fast enough. I don't think this is an inherent problem with decoding on an Android phone (for example, processing limitations) because it does the same thing for very low bitrates— also again, it DID work when I was using ffmpeg to encode. If I omit certain NAL units, the decoder can start to keep up. Since I'm using Cyanogenmod 10.1, bumping up the minimum CPU frequency helps, too.

    Edit :

    Here is a log of the Android client, as well as a log highlighting the garbage collector specifically—

  • MediaCodec hardware decoder much slower with different server configuration ?

    19 octobre 2013, par mathieujofis

    I've been using the Android MediaCodec in order to (hardware) decode H.264 frames on my Galaxy S4 coming from a Live 555 RTSP live (real-time) stream. After changing my Live 555 server configuration from using ffmpeg (with x264) to encode frames, to using strictly x264 to encode frames, the time to decode frames with MediaCodec takes much longer. Basically, MediaCodec can't keep up with the stream, and displays the video in slow motion, getting slower and slower as time goes on. Going back to ffmpeg isn't a solution for me, because I need the ability to encode into discrete NAL units, rather than a whole frame like ffmpeg does.

    I was wondering if this was either : A) An issue with the way my server is encoding NAL units, or B) An issue with my Android client, specifically the way it is receiving and decoding NAL units.

    My encoding configuration with x264 is :

    x264_param_default_preset(&param,"ultrafast", "zerolatency:fastdecode");
    param.i_threads = 1;
    param.i_bframe = 1;
    param.i_width = image_width;
    param.i_height = image_height;
    param.i_fps_num = 60;
    param.i_fps_den = 1;
    param.i_keyint_max = 10;

    param.rc.i_rc_method = X264_RC_ABR;
    param.rc.i.bitrate = 6000;
    param.i_sps_id = 7;
    param.b_repeat_headers = 1;
    param.b_annexb = 0;

    My Android MediaCodec client is set up as follows :

    I receive each individual NAL unit on a separate Live 555 RTSP client thread. Each NAL is put into a queue along with its size and presentation time. A separate decoder thread grabs NALs from this queue, and if there are none available, waits until there are.

    Some notes :

    What I generally see happen is the queue starts filling up with NALs, instead of staying close to empty. So, I know that the decoder thread is not working fast enough. I don't think this is an inherent problem with decoding on an Android phone (for example, processing limitations) because it does the same thing for very low bitrates— also again, it DID work when I was using ffmpeg to encode. If I omit certain NAL units, the decoder can start to keep up. Since I'm using Cyanogenmod 10.1, bumping up the minimum CPU frequency helps, too.

    Edit :

    Here is a log of the Android client, as well as a log highlighting the garbage collector specifically—
