  • 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" (...)

  • Read a growing MFX file for live streaming sports match file [closed]

    12 novembre 2024, par Sumit Chaudhary

    I'm struggling to read a growing MXF file in real time for a live sports streaming project in python. I can read the video in 5-minute chunks provided by the recording software, for the same match and I’m able to load the full file (around 750GB) once the match is over and file is complete. However, I need to process the file as it’s still growing. Any suggestions on how to approach this ?

    Use variance metric for integral projection vector match

    This commit replaces the SAD with variance as metric for the
    integral projection vector match. It improves the search accuracy
    in the presence of slight light change. The average speed -6
    compression performance for rtc set is improved by 1.7%. No speed
    changes are observed for the test clips.

  • vp9 : match another find_ref_mvs() bug in libvpx.

    vp9 : match another find_ref_mvs() bug in libvpx.

    If we find a second non-sub8x8 motion vector for a non-first sub8x8
    
block, and the clamped value is identical to the first non-sub8x8
    
motion vector, then the resulting nearmv motion vector is forced to
    
zero.
