  • 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" (...)

  • Revision 86bb6df005 : Fixed point reference picture scaling Fixed point scaling factors are calculate

    10 juin 2013, par Tero Rintaluoma

    Changed Paths :
     Modify /vp9/common/vp9_blockd.h


     Modify /vp9/common/vp9_reconinter.c


     Modify /vp9/encoder/vp9_rdopt.c



    Fixed point reference picture scaling

    Fixed point scaling factors are calculated once for each
    reference frame by using integer division. Otherwise fixed point
    scaling routines are used in all scaling calculations. This makes it
    possible to calculate fixed point scaling factors on device driver
    software and pass them to hardware and thus avoid division on hardware.

    TODO :
    - Missing check for maximum frame dimensions
    (currently scaling uses 14 bits)
    - Missing check for maximum scaling ratio
    (upscaling 16:1, downscaling 2:1)

    Problems :
    - Straightforward fixed point implementation can cause error +-1
    compared to integer division (i.e. in x_step_q4). Should only
    be an issue for frames larger than 16k.

  • How to write audio in AVFrame sample by sample or channel by channel with C++

    26 juillet 2021, par Little Max

    I'm trying to make stereo avframe from two stereo frame. In resulted frame I want to have different audio to be in different channels. But the problem is that I don't know how to write audio to frame->data field sample by sample in code. Is there any way like writing bytes by bytes or set channels data somehow using c++ ?
