    We don’t claim to be the only ones doing what we do ... and especially not to assert claims to be the best either ... What we do, we just try to do it well and getting better ...
    The following list represents softwares that tend to be more or less as MediaSPIP or that MediaSPIP tries more or less to do the same, whatever ...
    We don’t know them, we didn’t try them, but you can take a peek.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;

  • Qualité du média après traitement

    21 juin 2013, par

    Le bon réglage du logiciel qui traite les média est important pour un équilibre entre les partis ( bande passante de l’hébergeur, qualité du média pour le rédacteur et le visiteur, accessibilité pour le visiteur ). Comment régler la qualité de son média ?
    Plus la qualité du média est importante, plus la bande passante sera utilisée. Le visiteur avec une connexion internet à petit débit devra attendre plus longtemps. Inversement plus, la qualité du média est pauvre et donc le média devient dégradé voire (...)

                        + "[0:v][overlay_scaled]overlay=eval=init:x=W*" + 0
    
                        + ":y=H*" + 0;
    

    
String[] bb = new String[]{ "-i", inputFile,"-itsoffset", "0", "-i", inputGif, "-filter_complex", strFilter, "-preset", "ultrafast", "-g", "120", outputFile };

  • ffmpeg - Frames flip upside-down when using -c:v copy

    26 décembre 2019, par Berndi

    I tried to just copy (a period of time of) an AVI-Video into another newly created AVI-file using ffmpeg’s copy option.
    (On Windows 32-bit)

    ffmpeg -i "C:\Temp\zzz\myAvi.avi" -c copy -t 00:00:10 "C:\Temp\zzz\myAviNew.avi"

    Why are the pictures flipped upside-down in the resulting file ?
    (Also the generated new audio is a little distorted.)

    Using the same command again on the newly created file will not flip them back again - the pictures stay upside down.
    Why this ? Is it a bug ?

    Console brings the following output :
