  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • ffmpeg fastest way to convert videos avi to mp4 [migrated]

    5 novembre 2013, par user2938660

    I have server which has :

    • 8x3,4 (sandy bridge cpu)
    • 10gb ram

    i tried different combinations to convert vvideos i mean avi to mp4 but it takes so long :
    - 20mins= 200mb

    maybe there is some ffmpeg command which does this much faster ?

  • FFMPEG on ubuntu wont start. Process is just killed [on hold]

    I am trying to run a command on ffmpeg. When I run on my local computer it works fine but when running on my ubuntu server it won’t start. It just keeps giving an error saying the process is killed when it trys to start. Is this something related to memory or a different issue ?

    Please help me to understand what I am doing wrong.

    I am executing the following command for making a live stream

    Executing: powershell gst-launch-1.0 filesrc location=D:/testVODs/sample.mkv ! matroskademux name=dmx dmx. ! h264parse config-interval=1 ! queue ! rtspclientsink profiles=avpf protocols=udp location="rtsp://192.168.1.1:8554/8c83bea4-b49b-4776-9c0f-d11e9e8898f0/1" name=rtsp_out dmx. ! opusparse ! queue ! rtsp_out.

    and in the result, I see that the execution ended after 00:01:21 which means that the stream is ended successfully after my video ended :

rtsp://192.168.1.1:8554/live/8c83bea4-b49b-4776-9c0f-d11e9e8898f0/1: Unknown error

    why method SETUP failed as 461 Unsupported transport and how it can be solved ?

    I tried to use different ffplay, ffmpeg commands, but all of them lead to the same result.
    If I do not use rtsp_trasport command I have the error [udp @ 000001d1ab52c300] ’circular_buffer_size’ option was set but it is not supported on this build (pthread support is required)
    and the same 461 Unsupported transport

    Before I added "profiles=avpf" to my stream creation request I managed to play it successfully with "rtsp_transport tcp".
    But now profiles=avpf is required and I need to understand how to deal with it
