  • 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 (...)

  • MediaSPIP en mode privé (Intranet)

    17 septembre 2013, par

    À partir de la version 0.3, un canal de MediaSPIP peut devenir privé, bloqué à toute personne non identifiée grâce au plugin "Intranet/extranet".
    Le plugin Intranet/extranet, lorsqu’il est activé, permet de bloquer l’accès au canal à tout visiteur non identifié, l’empêchant d’accéder au contenu en le redirigeant systématiquement vers le formulaire d’identification.
    Ce système peut être particulièrement utile pour certaines utilisations comme : Atelier de travail avec des enfants dont le contenu ne doit pas (...)

  • ffplay 461 Unsupported transport

    28 octobre 2017, par Cerato

    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

    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 ?

  • 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 ?
