  • Websites made ​​with MediaSPIP

    2 mai 2011, par

    This page lists some websites based on MediaSPIP.

  • Creating farms of unique websites

    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" (...)

  • Submit enhancements and plugins

    13 avril 2011

    If you have developed a new extension to add one or more useful features to MediaSPIP, let us know and its integration into the core MedisSPIP functionality will be considered.
    You can use the development discussion list to request for help with creating a plugin. As MediaSPIP is based on SPIP - or you can use the SPIP discussion list SPIP-Zone.

  • avutil : add hwcontext_amf.

    15 octobre 2024, par Dmitrii Ovchinnikov
    avutil : add hwcontext_amf.

    Adds  hwcontext_amf, enabling a shared AMF context for encoders,
    
decoders, and AMF-based filters, without copy to the host memory.
    
Code also was tested in HandBrake.
    

    Benefits :
    
 - Optimizations for direct video memory access from CPU
    
 - Significant performance boost in full AMF pipelines with filters
    
 - Integration of GPU filters like VPP, Super Resolution, and
    
    Compression Artefact Removal(in future plans)
    
 - VCN power management control for decoders.
    
 - Ability to specify which VCN instance to use for decoding
    
   (like for encoder)
    
 - AMD will soon introduce full AMF API for multimedia accelerator MA35D
    
   - With AMF API, integration will be much easier :
    
      GPU and the accelerator will have the same API
    
   - including encoder, decoder, scaler, color converter,
    
      Windows and Linux.

    Changes by versions :
    
v2 : Header file cleanup.
    
v3 : Removed an unnecessary class.
    
v4 : code cleanup and improved error handling
    
v5 : Fixes related to HandBrake integration.
    
v6 : Sequential filters error and memory leak have been fixed.

  • 3 hidden Piwik features you likely don’t know, that will make you more productive

    17 janvier 2017, par InnoCraft — Community

    At Piwik and at InnoCraft, we always aim to make features as intuitive as possible. Having thousands of features in Piwik and having to find a balance between beginners and advanced users can sometimes be a challenge. Sometimes this even leads to building hidden features that are mainly targeted for power users. The list below shows three of them, did you know any of them yet ?

    BTW : If you don’t have Piwik yet, you can try them on our Piwik Demo.

    1. Search

    When you press the letter “f”, it will activate the search bar in the top left. Once you start typing something, it will show matching reports. Say you want to view reports about “devices” but don’t remember exactly which category it is in, simply start typing “devices” and the matching entry will show up without even having to move the mouse.

    The search bar also searches for matching websites and segments. Use the arrow up and down keys to select the entry you want and press enter to confirm the selection.

    Say you don’t remember the name of a report but you know it is listed under the category “Visitor”, then start typing the name of the category and it will show all related reports.

    2. Zen Mode

    When you press the letter “z”, it will activate the Zen Mode which lets you focus on the reports and content by removing the header and left menu. To disable the Zen Mode, simply press “z” again.

    This is especially useful in combination with the search bar mentioned above, as it enables you to quickly switch between reports, websites and segments even while menu and header are hidden.

    3. Faster period change

    Changing the displayed period is a task you likely perform quite often when analyzing reports. Usually, you would first select the period and then press the button “Apply” in the date selector. Instead, you can simply double click the name of the period and it will immediately load the selected period without having to click on the “Apply” button.

    What are your hidden features in Piwik ?

    Let us know by getting in touch with us or share it with us on Facebook or Twitter.
