  • Keeping control of your media in your hands

    13 avril 2011, par

    The vocabulary used on this site and around MediaSPIP in general, aims to avoid reference to Web 2.0 and the companies that profit from media-sharing.

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • FFMPEG - Watermark video with same quality and filesize [duplicate]

    19 février 2018, par ddlshack

    This question already has an answer here :

    I have some videos, and I’d like to watermark them with a transparent PNG. Here’s what I’ve tried :

    ffmpeg -i 9.flv -vf "movie=logo.png [watermark];[in][watermark] overlay=10:10 [out]" 9_w.flv

    However, bitrate or quality is not preserved. Preferably I’d like ffmpeg to re-encode the file with exactly the same settings as the original file (same codecs, bitrate). If thats not easily possible, I’d like to encode with a specific codec, but preserving ’quality’, however that is measured.

  • Revision 2e05341ab4 : Fix bad speed settings interaction. The flag x->skip_recode interacts badly wit

    20 mars 2014, par Paul Wilkins

    Changed Paths :
     Modify /vp9/encoder/vp9_encodeframe.c



    Fix bad speed settings interaction.

    The flag x->skip_recode interacts badly with
    the cpi->sf.use_nonrd_pick_mode and
    cpi->sf.skip_encode_sb speed settings.

    Restricting the use of the skip_decode flag when
    these other speed choices are in use helps quality
    for speeds 3 and 4 by a large amount with only a
    small impact on speed.

    Average improvmentes for 2 pass speed 4 :
    Derf +8.8%
    Yt + 10.53%
    Std-Hd +6.95%
    yt-hd + 22.95%

  • Convert video after upload [duplicate]

    15 novembre 2016, par BlackFayah

    This question already has an answer here :

    I am running a service where people can upload videos. Because of the large file sizes I would like to convert those videos after uploading.

    I want it so that when the upload is done, a PHP script is called in which the video gets converted (using FFMPEG). When the conversion is done, the user receives a notification that the video is ready to use.

    I am thinking of a separate PHP script that uses the path sent in POST. It will then call the FFMPEG line within shell_exec(). But how can I get it to run in the background and send a notification to the user when the process is done ?
