  • 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" (...)

  • Installing full multimedia stack on server (ffmpeg,mp4box,sox,mplayer)

    29 avril 2015, par hdezela

    I’ve had a trusty text file with all(?) the steps I need to set up a full multimedia stack on a RHEL compatible server (CentOS, AWS Linux, etc.) for a few years now. However, sometimes some things are missing and I need to revise it. I know it is not complete so I’m asking for suggestions/modifications in order to get a good - and public - list of how to install all this stuff easily.

    Ideally, I want to be able to run through the file and end up with a system that’ll take any media file and be able to convert/encode/decode/whatever with it.

    This is what I have :

    yum install mesa-libGL-devel mesa-libGLU-devel libXi-devel libXmu-devel freeglut-devel freeglut ncurses-devel
    
cd /usr/local/src
    
mkdir /usr/local/src/tmp
    
chmod 777 /usr/local/src/tmp
    
export TMPDIR=/usr/local/src/tmp

  • How can I create a FULL copy of a decoder ?

    28 avril 2015, par damicolo

    I’m writing a video decoder (using FFMPEG/AVCodec) for a custom implementation of an mpeg4 video stream. The peculiarity of this video stream is that it could split into many "son" streams creating many P frames based on the same parent. The video stream I’m trying to decode is actually a sort of "video tree". Something like this :

    I <--P <--P <---------------------P <-------------- P <------------ P
    
           \ <--P <--P <--P        \ <--P <--P       \ <--P <--P

    I’ve already wrote a basic decoder which works fine when I decide to follow one path, the problem is when I try to follow more than one path in the video tree. At this point I need to "fork" my decoder to follow two different video streams. the split could occur not only after a key frame, but even after a P frame, so I need to duplicate the AVCodecContext (I use avcodec_copy_context) but it seems to create new decoder from a clean status.. it seems to ignore the previous video status, so the decoded P frames are "applied" to an empty video frame.
    Probably copying the context using avcodec_copy_context is not enough... Any suggestion ? How can I duplicate the context and the complete status of the decoder ?
    Or, is there any other way to decode my stream using references ?
    Thanks !
