    This page lists some websites based on MediaSPIP.

  • 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" (...)

    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

  • ffmpeg url protocol - annoying issue with url_seek

    7 juin 2014, par Gieas

    I’m trying to add my own URL protocol to my improved dranger’s video player using ffmpeg.

    The URLPRotocol is : http://www.ffmpeg.org/doxygen/2.1/structURLProtocol.html

    It seems that (For some weird reason) ffmpeg calls my ’url_seek’ before the movie even starts.

    The function prototype is the same as lseek’s :

    int64_t my_url_seek(URLContext *h, int64_t pos, int whence)

    FFmpeg first calls the function with the values : POS = 0 , WHENCE = 65536

    According to ffmpeg’s docs the value 65536 (AVSEEK_SIZE) means that ffmpeg wants the video size - so, my server responses to it with the video size.
    But after that, it tries to seek with weird values :
    POS = 8827210, WHENCE = 0, POS = 9912, WHENCE = 0 and so on.. (Same values all the time)
    Anyways, according to ffmpeg’s doc whence should return the current position of the file (measured from the beginning of the file in bytes) and that is what I’m giving him (Except special case when it wants the video size as I mentioned before) - but it still doesn’t work.

    I don’t get it. What is it trying to do ? It can’t really be my fault because I did just use dranger’s video player and registered my own protocol. anyone has any idea what’s going on here ?

  • Error installing pHash on Ubuntu

    7 octobre 2015, par Hyperion

    So I was trying to install the pHash libraries on Ubuntu. I’ve installed all the required packages running this command :

    apt-get install libavformat-dev libmpg123-dev libsamplerate-dev libsndfile-dev cimg-dev libavcodec-dev ffmpeg libswscale-dev

    Then I run ./configure and everything seems ok, I got this :
