    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" (...)

  • Recording RTP VP8 packets with FFMPEG with named pipe

    6 août 2015, par Filipe Apolinário

    I’m developing a WebRTC video session recorder, in a gateway developed in C++, where I only have access to individual RTP packets.

    When a session starts, I create two threads one that initializes a named pipe and an other that starts FFMPEG to fetch data from that pipe and store it in a matroska file, with the command :

    ffmpeg -i \\.\pipe\screenRec -f matroska D:\djhfifj.mkv

    Whenever I receive an RTP packet I send it through the pipe to FFMPEG. Although all communication is working fine, FFMPEG does not seem to be recognizing the RTP packet :

    Is it possible to make FFMPEG understand that the packet sent is RTP with VP8 ?
