    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 (...)

  • 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" (...)

  • How to match ONVIF Camera services with FFMPEG restreaming

    2 janvier 2018, par Milen

    This is the situation,

    I have an IP Camera from which I can view the video associated on an rtsp video streaming.

    I also have a software, developed with ffmpeg which takes the camera video, makes some changes to the image and restreams another video, on another rtsp address. The output address rtsp :// :/stream.

    Finally, I have an NVR device which is configured to record any camera streaming or substreaming video. To make it work, you have to determine the camera IP and an ONVIF port.

    So what I want to do and I dont know how, is to add the camera to the NVR but change the rtsp address. Or maybe, simulate an ONVIF camera service, and associate it with my generated rtsp video. Then, add this ""camera"" to the NVR.

    Any answers that consist in recording the video in any other way than using the NVR, will not be useful for me

    EDIT :

    The first option which consists on adding the camera to the NVR and change the rtsp address didnt work, because the device doesn’t support that. So I want to know how to implement (any language or platform) an ONVIF server which copy the camera service but change the rtsp address.

    I downloaded a virtualbox machine which work as ONVIF server, but still didnt know how to change the protocol so It gives my rtsp address to the NVR, because the code was a very close one.

  • FFmpeg X264 multithread decoding

    16 novembre 2013, par Xin He

    I want to do H264 multithread decoding using FFmpeg.
    First I use X264 to encode yuv420 to file.x264
    ./x264 -o file.x264 —slices 4 —input-res 1280x720 —fps 25 file_560x420.yuv

    The slices count is 4.

    However, when I use FFmpeg to decode,
    ./ffmpeg -y -threads 4 -thread_type slice -i file.x264 final.yuv

    FFmpeg calls func"execute_decode_slices" four times, not in a multithread way.
    I also found that in *execute_decode_slices(h, context_count)*, the context_count is 1.
    FFmpeg call this 4 times.

    Could someone help to solve this problem ?

    Thanks very much !
