  • Mise à disposition des fichiers

    14 avril 2011, par

    Par défaut, lors de son initialisation, MediaSPIP ne permet pas aux visiteurs de télécharger les fichiers qu’ils soient originaux ou le résultat de leur transformation ou encodage. Il permet uniquement de les visualiser.

  • Compile Shotdetect on CentOS 7

    14 septembre 2015, par BitLegacy01

    I’m migrating a service from a Debian server to a CentOS 7 one.

    The service needs the Shotdetect command (github , official site).

    I could not make it work on CentOS though I followed all steps :

    1. Compile ffmpeg compilation guide

      1. Install needed packages

        # yum install gd-devel libxml2-devel libxslt-devel clang libvpx libvorbis

      2. Add pthread in the CMakeList file, in TARGET_LINK_LIBRARIES, because it throws an lpthread missing in linker error

      3. Compile Shotdetect

        # FFMPEG_DIR="/root/ffmpeg_build"  ./compile.sh cmd

  • 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 ?
