  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • Correct ffmpeg scale command syntax

    10 novembre 2015, par user3132858

    I am new to ffmpeg and need some help with the correct syntax for a scale command I found here.

    Below is my code :

    $width=300;
    
$height=200;
    
$aspect=$width/$height;
    

    

    
$command = "/usr/local/bin/ffmpeg -y -i 1.mp4 -vf scale=min(1\,gt(iw\,".$width.")+gt(ih\,".$height.")) * (gte(a\,".$aspect.")*".$width." + \
    
lt(a\,".$aspect.")*((".$height."*iw)/ih)) + not(min(1\,gt(iw\,".$width.")+gt(ih\,".$height.")))*iw : \
    
min(1\,gt(iw\,".$width.")+gt(ih\,".$height.")) * (lte(a\,".$aspect.")*".$height." + \
    
gt(a\,".$aspect.")*((".$width."*ih)/iw)) + not(min(1\,gt(iw\,".$width.")+gt(ih\,".$height.")))*ih  -b 1200k -acodec aac -strict -2 2.mp4 ";

    Video is successfully converted however, the scaling does not go trough.

    The code is copied word for word, I only make two changes :

    • removed the " before scale word and from the end
    • replaced the $FW with $width, $FH with $height and $FA with $aspect.

    Any suggestion at what might be wrong ?

  • How to make words in ASS subtitles appear one at a time ?

    21 septembre 2022, par ThaDon

    I am trying to burn subtitles into a video such that they appear in a word-by-word fashion instead of all at once.

    



    What I mean by this is, a word will appear, then another word will appear next to it, and so on. Eventually the line will clear, then repeat.

    



    Example :

    



    A video shows a person speaking about chess. Subtitles at the bottom of the screen say “winning”. Moments later, the subtitles change to “winning a”, then “winning a piece”, later “winning a piece now” and so on. Each consecutive word instantly appears in whole, but each word only appears when the speaker says it.

    



    I thought I could create an Advanced Substation Alpha file where subtitles share the same end-time but differing start times, however FFMPEG doesn't seem to cope very well when rendering the file :

Dialogue: 0,0:00:01.50,0:00:03.46,Default,,0,0,0,,subtitle


    



    The idea being that I'm would appear, then 1 second later a would show up next to it followed by subtitle a half second later
