  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • 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 (...)

  • Fix mp4 file downloaded with rtmpdump

    18 octobre 2014, par Mega-X

    Some days ago I’ve downloaded a mp4 file using rtmpdump but, unluckily, I didn’t know about the --live option which I needed to put in order to download that mp4 correctly. So now I have a mp4 file which jumps back and I cannot download that another time since it is not online anymore. How can I fix the corrupt mp4 file ? I’ve tried with ffmpeg -i old_file.mp4 new_file.mp4 but the file is still corrupted.

  • ffmpeg rotate and resize

    23 août 2014, par user1321964

    I’m trying to resize a movie and to rotate it counter-clockwise using ffmpeg.
    I can achieve one or the other ok individually

    ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

    OR

    ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

    but if I try to do both, either-

    ffmpeg -i MVI_8189.MOV -s 720x406 -ss 00:00:12 -t 00:00:05 resize.MOV

    ffmpeg -i resize.MOV -vf "transpose=2" toutp.MOV

    OR

    ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

    ffmpeg -i rotate.MOV -s 406x720 toutp.MOV

    the final movie does not play, only audio, no video ; neither previewing in Finder, nor in Quicktime. More seriously once I have attempted to play it, I can’t then play any other movie whatsoever (only audio) - quicktime won’t quit, constantly need to force-quit it. The only way to then restore seems to be reboot OS-X

    This though does work -

    ffmpeg -i MVI_8189.MOV -vf "transpose=2" -ss 00:00:12 -t 00:00:05 rotate.MOV

    ffmpeg -i rotate.MOV -s 720x406 toutp.MOV

    but doesn’t do what I want - it stretches the movie in the wrong direction

    Any ideas ?

  • Convert .mp3 to .mov or .mp4 on iOS SDK [on hold]

    3 août 2014, par Sebastian

    I’m a little stuck with an mp3 conversion.

    At this time, my app does the following :

    1. Receive an input text.
    2. The app generate a speech using an online API and download the generated .mp3 file to the app document’s folder.

    Now I need to convert the .mp3 to .mov or .mp4 and then grab it to the camera roll, so the user can share the video on Facebook, Whatsapp, or wherever he wants.

    Is there some easy and memory friendly way to convert from .mp3 to .mp4 without "writing a video" ?
    Thank you !
