  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • 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" ;

    ffmpeg -i input.mkv -vcodec copy -acodec copy output.264

    It works without errors, but when I try to play output.264 using ffplay :

    ffplay -f h264 -i output.264

    ffplay response is :

  • error : av_interleaved_write_frame() : Unknown error

    12 avril 2014, par John Qualis

    I am new to ffmpeg. I am trying to stream my webcam using ffmpeg (x264 encoding) on a windows machine to ffserver on a linux server and restream it. I am getting the following error : av_interleaved_write_frame() : Unknown error
    I checked about it on the net and came across mails which said it could be related to version mismatch between ffmpeg and ffserver. I made sure that all libraries that are used by ffmpeg and ffserver have the same version. I am still getting this error. Appreciate any help in solving this issue.

    I am using the following command :

     .\ffmpeg.exe -f dshow -i video="Webcam C170":audio="Microphone (3- Webcam C170)" -an -g 94 -vcodec libx264 -b:v 512k -r 30 -f flv http://AA.BB.CC.DD:8090/feed1.ffm

    I get the followoing errors -

    Last message repeated 1 times
