  • Les vidéos

    21 avril 2011, par

    Comme les documents de type "audio", Mediaspip affiche dans la mesure du possible les vidéos grâce à la balise html5 .
    Un des inconvénients de cette balise est qu’elle n’est pas reconnue correctement par certains navigateurs (Internet Explorer pour ne pas le nommer) et que chaque navigateur ne gère en natif que certains formats de vidéos.
    Son avantage principal quant à lui est de bénéficier de la prise en charge native de vidéos dans les navigateur et donc de se passer de l’utilisation de Flash et (...)

  • Possibilité de déploiement en ferme

    12 avril 2011, par

    MediaSPIP peut être installé comme une ferme, avec un seul "noyau" hébergé sur un serveur dédié et utilisé par une multitude de sites différents.
    Cela permet, par exemple : de pouvoir partager les frais de mise en œuvre entre plusieurs projets / individus ; de pouvoir déployer rapidement une multitude de sites uniques ; d’éviter d’avoir à mettre l’ensemble des créations dans un fourre-tout numérique comme c’est le cas pour les grandes plate-formes tout public disséminées sur le (...)

  • Extract Video Frames In Python

    28 février 2024, par TheNone

    I want to extract video frames and save them as image.

    



    import os, sys
from PIL import Image

a, b, c = os.popen3("ffmpeg -i test.avi")
out = c.read()
dp = out.index("Duration: ")
duration = out[dp+10:dp+out[dp:].index(",")]
hh, mm, ss = map(float, duration.split(":"))
total = (hh*60 + mm)*60 + ss
for i in xrange(9):
    t = (i + 1) * total / 10
    os.system("ffmpeg -i test.avi -ss %0.3fs frame%i.png" % (t, i))


    



    But I have this error :

Supported file protocols:
 file: pipe: udp: rtp: tcp: http:
Frame size, frame rate abbreviations:
 ntsc pal qntsc qpal sntsc spal film ntsc-film sqcif qcif cif 4cif
Motion estimation methods:
 zero(fastest) full(slowest) log phods epzs(default) x1 hex umh iter

Note, the names of encoders and decoders dont always match, so there are
several cases where the above table shows encoder only or decoder only entries
even though both encoding and decoding are supported for example, the h263
decoder corresponds to the h263 and h263p encoders, for file formats its even
worse
