  • Demande de création d’un canal

    12 mars 2010, par

  • 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 (...)

  • 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.

  • ffmpeg get machine readable output

    15 mai 2017, par J.S

    I am trying to find a way to get FFmpeg to return a machine readable output. basically, I just want to know if video conversion was successfull.

    I am calling FFmpeg from go code.

    output, err := exec.Command("ffmpeg", "-i", source, "-vcodec", "h264", "-acodec", "aac", "-strict", "-2", destination).CombinedOutput()

    The above code executes this command :

    ffmpeg -i /tmp/pitchVideo-1494844705-102.mp4 -vcodec h264 -acodec aac -strict -2 /tmp/1494844705.mp4

    I get the following output :

  • `ffmpeg` can not dump RTSP streaming but `ffplay` can play it

    18 juin 2019, par newBike

    I want to dump the RTSP streaming into a file.

    ffmpeg -y-i rtsp://172.19.12.37/live.sdp -acodec copy -vcodec copy tmp.mp4

    But I got errors,

    [mp4 @ 0x7fe98400dc00] track 1: could not find tag, codec not currently supported in container

    Could not write header for output file #0 (incorrect codec parameters ?): Operation not permitted

    However, I can play the RTSP streaming by any media player, what was wrong with my ffmpeg command ?

    Is there any options can dump any stream and dump it into identical video format.
