  • La file d’attente de SPIPmotion

    28 novembre 2010, par

    Une file d’attente stockée dans la base de donnée
    Lors de son installation, SPIPmotion crée une nouvelle table dans la base de donnée intitulée spip_spipmotion_attentes.
    Cette nouvelle table est constituée des champs suivants : id_spipmotion_attente, l’identifiant numérique unique de la tâche à traiter ; id_document, l’identifiant numérique du document original à encoder ; id_objet l’identifiant unique de l’objet auquel le document encodé devra être attaché automatiquement ; objet, le type d’objet auquel (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • tcp : Explicitly convert a pointer to a boolean integer

    9 septembre 2013, par Martin Storsjö
    tcp : Explicitly convert a pointer to a boolean integer

    This fixes warnings about making integers from pointers without
    
a cast, and avoids the theoretical case where the lower 32 bits of
    
the pointer would all be zero where the implicit cast wouldn’t give
    
the right result.

  • How can I stream mjpeg file as rtsp

    24 août 2013, par Ilya Yevlampiev

    We have an mjpeg video, obtained from the webcam and stored into *.avi file, still encoded as mjpeg.

    We need to restream this file as rtsp (and stil preserve the mjpeg there, i.e. no decoding). The goal is to emulate the webcam this video was obtained from for the software that processes the video. The file can be open with vlc/ffplay with no problems. The ffmpeg behaves like it is streaming it, however, ffplay/vlc can't open this stream.

    We tried to stream if with gstreamer.

    1) we fount no free rtsp sink element for gstreamer pipeline. So, is there a free analogue for rtspsink to launch this pipeline with gst-launch ? we need and only cast, so we don't need so advanced element as rtspsink is.

    2) we also tried to build own simple rtsp server as described in http://weeklybuild.com/2013/01/creating-an-rtsp-stream-with-gstreamer/

    replacing videotestsrc with filesrc ; but what kind of elements we should use there ? usage of an only filesrc doesn't help ; we get the same problem as if we stream with ffmpeg. But what kind of lements we need there, if we dont' wan to decode/encode it, just to stream the file (to reproduce the thing what the webcam actually does).
