  • 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" (...)

  • avcodec/hevcdec : apply H.274 film grain

    29 septembre 2021, par Niklas Haas
    avcodec/hevcdec : apply H.274 film grain

    Similar in spirit and design to 66845cffc3bbb, but slightly simpler due
    
to the lack of interlaced frames in HEVC. See that commit for more
    
details.
    

    For the seed value, since no specification for this appears to exist, I
    
semi-arbitrarily decided to base it off the POC id alone, since there's
    
no analog of the idr_pic_id in HEVC's I-frames. This design is stable
    
across remuxes and seeks, but changes for adjacent frames with a period
    
that's typically long enough not to be noticeable, which makes it
    
satisfy all of the requirements that a film grain seed should have.
    

    Tested with and without threading, using a patch to insert film grain
    
metadata artificially (for lack of real files containing film grain).

    avcodec/av1_vaapi : setting 2 output surface for film grain

    VAAPI needs 2 output surface for film grain frame. One used for
    
reference and the other used for applying film grain and pushing
    
to downstream.

    avcodec/h264_picture : don't assume Film Grain Params side data will be present

    If a decoding error happens before frame side data is allocated, this assert may be
    
triggered. And since applying film grain is not enforced (we just warn it wasn't
    
applied and move on), we can just do that in such scenarios.
    

    Fixes : Assertion failure
