  • 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" (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Revision 9d427884e9 : Fixed libyuv image copy for high bitdepth When scaling and extending frames in

    8 mai 2014, par Peter de Rivaz

    Changed Paths :
     Modify /third_party/libyuv/source/scale.c



    Fixed libyuv image copy for high bitdepth

    When scaling and extending frames in high bitdepth,
    there is a special case when no scaling is required.
    This triggers a code path that calls CopyPlane16.
    In this case the high bitdepth code was not
    copying enough bytes.

  • ffmpeg compress video in fast motion in high quality

    1er juin 2020, par Estatistics

    I would like to compress a video and in the same time to be in fast motion, and this must have as a result a high quality fast motion video.

    



    I tried to run this ffmpeg command which compress video in high quality and in fast motion ( four times faster) :

    



    ffmpeg -i video_to_encode.avi  -r 16 -crf 18  -vcodec libx264  -filter:v "setpts=0.25*PTS" -vb 10M -vf scale=1280:720 video_output.avi


    



    However, while video is compressed in high quality, the command for fast motion -filter:v "setpts=0.25*PTS" is not executed. I have an idea that "-filter:v" may must be removed. Is that right ?

    


  • How to do audio expansion/normalization (emphasise difference between high and low)

    28 novembre 2018, par foobar

    I’m trying to find way to emphasise the difference between high and low points in the audio. I can’t seem to find documentation on how to do this - perhaps this can be done with ffmpeg. Would really appreciate some pointers from someone who knows more about signal processing.
