  • 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 (...)

  • 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 (...)

  • encode video to HD Format @ 1500 kbps = 1280x720 using ffmpeg in php

    15 octobre 2014, par Wikki

    I am new to ffmpeg and I have to convert videos to mp4 using H.264. I need SD format with below as well as HD format. I used SD format conversion with below command.

    $cmd = "ffmpeg -i $in -vcodec libx264 -b 700k -bf 3 -b_strategy 1 -coder 1 -qmin 10 -qmax 51 -sc_threshold 40 -flags +loop -cmp +chroma -me_range 16 -me_method hex -subq 5 -i_qfactor 0.71 -qcomp 0.6 -qdiff 4 -directpred 1 -flags2 +fastpskip -dts_delta_threshold 1 -acodec libfaac -ab 128k $out";

    Now, i need to do HD format conversion : HD Format @ 1500 kbps = 1280x720

    Please guide me how run command for HD conversion. I have ffmpeg 0.6 version installed on server and unfortunately I cannot upgrade this or compile new version.

    Please guide me.

    thanks

  • why do andorid camera and gopros not use b-frames ?

    26 août 2021, par Photo_Survey

    I am using ffmpeg to extract the gop-structure of videos, which I recorded with my Smartphone (Samsung Galaxy A51) and my GoPro (Hero 7 Black).
The gop-structures I get all look like this : IPPPPPPPPPPPPPP. The videos of the different devices only differ in the number of P-Frame per gop-structure. The ffmpeg code I used fpr this is the following :

    


    ffprobe -show_frames inputvideo.mp4 -print_format json
Now my question is why the encoders of both devices don't use B-Frames ? Is is it because the encoding of B-Frames is more complicated for the Hardwar or something like this ?
