  • Configurer la prise en compte des langues

    15 novembre 2010, par

    Accéder à la configuration et ajouter des langues prises en compte
    Afin de configurer la prise en compte de nouvelles langues, il est nécessaire de se rendre dans la partie "Administrer" du site.
    De là, dans le menu de navigation, vous pouvez accéder à une partie "Gestion des langues" permettant d’activer la prise en compte de nouvelles langues.
    Chaque nouvelle langue ajoutée reste désactivable tant qu’aucun objet n’est créé dans cette langue. Dans ce cas, elle devient grisée dans la configuration et (...)

  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • Run ffmpeg without outputting configuration information ?

    28 mars 2014, par Matt Joiner

    I'm invoking ffmpeg with subprocess.Popen, and trying to capture the stderr output and write it to logging.

    args = ['ffmpeg', '-i', path]
    
if start:
    
    args += ['-ss', start]
    
if end:
    
    args += ['-t', end]
    
args += [
    
    '-vcodec', 'copy',
    
    '-acodec', 'copy',
    
    '-scodec', 'copy',
    
    '-f', 'mpegts',
    
    '-y', '/dev/stdout']
    
self.child = subprocess.Popen(
    
    args,
    
    stdin=open(os.devnull, 'rb'),
    
    stdout=subprocess.PIPE,
    
    stderr=subprocess.PIPE)

    ffmpeg generates a lot of configuration information like the following :

    Prior to finally outputting the stuff I'd like to log :

    Seems stream 0 codec frame rate
    differs from container frame rate :
    47.95 (66893/1395) -> 23.98 (66893/2790) At least one output file
    must be specified

    Is there an option to prevent this excessive output ? Should I be doing it differently ?

  • Encode flv video with no audio with ffmpeg

    15 avril 2012, par David Bengoa

    I'm making an application that needs to convert videos to webm or mp4, it works great with all videos I've tried, but it fails if I use a flv file with no audio channels.

    If I pass the -an option, it works, but I can't do that because then all videos wouldn't have audio.

    Any ideas ?
