  • 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" (...)

  • Converting alpha channel of PNG sequence to Y channel of H265

    31 mai 2018, par Krumelur

    I have a video renderer that expects two H265 streams (YUV420) and I need to bake them to have one of them form an alpha mask to the other one. This is all solved and works well, however if I follow the instructions here :
    ffmpeg splitting RGB and Alpha channels using filter
    the alpha channel is slighly off. My hypothesis is that this is due to the alpha channel being scaled through the RGB->YUV matrix.

    The input is a sequence of PNG files, the output is two MKV files.

    The question is then : How can I tell FFmpeg to “reinterpret” the alpha channel as the Y channel without touching the pixel data ? Ideally by producing both MKV:s in one command line as shown in the other question, but at least without rewriting the source files.
