  • 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" (...)

  • avformat/matroskaenc : Rename functions to better reflect what they do

    avformat/matroskaenc : Rename functions to better reflect what they do

    EBML uses variable length integers both for the EBML IDs as well as for
    
the EBML lengths ; Matroska also uses them for the TrackNumber in
    
(Simple)Blocks and for the lengths of laces when EBML lacing is used.
    

    When encoding EBML lengths, certain encodings have a special meaning,
    
namely that the element has an unknown length. This is not so when
    
encoding general EBML variable length integers.
    

    Yet the functions called ebml_num_size() and put_ebml_num() had this
    
special meaning hardcoded, i.e. they are there to write EBML lengths and
    
not general EBML numbers. So rename them.

  • Sharing FFMPEG video stream data between processes

    21 juin 2016, par lgaravaglia

    I’m trying to find a method for sharing FFMPEG library datatypes between two processes.

    The project that I’m working on requires one process to buffer the FFMPEG stream that is being received and another process needs to read from the buffer and perform some actions on the video stream. Unfortunately, I can’t use a multi-threaded approach for this project. Due to some limitations in my system I have to use separate processes.

    The data that I would like to share I have placed in a general struct as follows :

    struct FFMPEGData {
    
AVFormatContext *pFormatCtx;
    
AVCodecContext  *pCodecCtx;
    
AVCodec         *pCodec;
    
AVFrame         *pFrame, dst;
    
AVPacket        *packet;
    
AVPacket* pack = new AVPacket[packetNum];
    
};

    The buffering process uses the format context and codec context to read the video stream and then it places packets in the AVPacket array pack. The other process should grab packets from the array and decode them, also using the format and codec contexts.

    I looked into the Boost Interprocess library, but that does not seem to be setup to handle this type of situation easily.

    Would anyone know a method for sharing my general struct between multiple processes ?
