  • 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 (...)

  • ffmpeg does not copy custom metadata

    20 juin 2015, par e110c0

    I’m trying to fix some videos made with an iDevice. The videos have a rotation in the metadata which is only understood by Apple and its software but noone else. Fixing this is quite simple, but I also would like to keep the other metadata in the files like the geolocation.

    I tried a couple of versions, all with the same result, e.g. :

    ffmpeg -i input.mov -vf vflip,hflip -map_metadata 0 -metadata:s:v:0 rotate=0  -acodec copy output.mp4

    This should work, it already gives the correct preview of metadata :

    I also tried to add the one tag I’m interested in by hand with

    -metadata:g location=+48.2683+007.7205+172.710/

    with no change in the result.

    Output as .mov doesn’t change anything, neither.

    Is there any trick to add non-standard metadata ? How do I get the location back in there ?

    Thanks in advance to anyone who can give some insight on this.

  • ffmpeg fix video orientation

    17 mars 2014, par PiTheNumber

    A video can contain a meta info about the camera orientation. For example iPhone and other phones set this flag if you turn the device. Problem is while some player read this info and rotate the video accordingly, other players do not.

    To fix this the video has to be rotated and the meta info needs to be set correctly.

    Does ffmpeg provide a fix for this or do I have to go the hard way (Read rotation, rotate, set meta data)
