  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • Organiser par catégorie

    17 mai 2013, par

    Dans MédiaSPIP, une rubrique a 2 noms : catégorie et rubrique.
    Les différents documents stockés dans MédiaSPIP peuvent être rangés dans différentes catégories. On peut créer une catégorie en cliquant sur "publier une catégorie" dans le menu publier en haut à droite ( après authentification ). Une catégorie peut être rangée dans une autre catégorie aussi ce qui fait qu’on peut construire une arborescence de catégories.
    Lors de la publication prochaine d’un document, la nouvelle catégorie créée sera proposée (...)

  • Récupération d’informations sur le site maître à l’installation d’une instance

    26 novembre 2010, par

    Utilité
    Sur le site principal, une instance de mutualisation est définie par plusieurs choses : Les données dans la table spip_mutus ; Son logo ; Son auteur principal (id_admin dans la table spip_mutus correspondant à un id_auteur de la table spip_auteurs)qui sera le seul à pouvoir créer définitivement l’instance de mutualisation ;
    Il peut donc être tout à fait judicieux de vouloir récupérer certaines de ces informations afin de compléter l’installation d’une instance pour, par exemple : récupérer le (...)

  • Vagrant provision fails to execute the next script without an obvious reason why

    14 juin 2016, par JakeTheSnake

    I’ve created/co-opted several bash scripts to provision my guest Ubuntu 14.04 OS ; the one giving me trouble right now is installing ffmpeg. When the script finishes, vagrant simply does nothing save for sending SSH keep-alives.

    Host OS : Windows 7 x64

    The last output before the infinitely repeating keep-alives is :

    I won’t include the other scripts for the sake of brevity. When logging into vagrant with the gui nothing seems out of the ordinary, and ffmpeg is available...but nothing else is provisioned. No RVM, no Nginx, nothing.

  • Is is possible to create custom shapes with ffmpeg ?

    7 mai 2021, par nardo

    I am trying to create a xstack layout with ffmpeg commands and from what I have seen online it is only possible to create rectangles with all the videos merge them into one video. However, I am trying to create a layout with custom shapes with X and Y coordinates.

    


    Example :
Example of the three input videos with custom layout and shapes

    


    Would this be possible with ffmpeg or do I need another library or open source code base to create this ?

    


  • why it is taking a lot of time to convert image to video in ffmpeg ?

    20 avril 2021, par al pacino

    Below is a snippet of code i am using to convert images into videos but It is taking around 3 minutes to convert image to 5 second video.
If I run the command on Image present on a directory then it converts images to videos very swiftly. but i need to use try except to catch ConnectionError..
can anyone tell what I am doing wrong ?

    


    video = []
video_list = []
for video in videos:
    try:
        r = requests.get(video, stream=True)
        print(r.status_code)
        if not r.status_code == 200:
            message = "broken url process could not be completed"
            return message
        if r.status_code == 200:
            if video.endswith(".jpg") or video.endswith(".png") or video.endswith(".jpeg"):
                filename = str(uuid.uuid4())
                url2 = download_path + filename +".webm"
                #cmd = "ffmpeg -loop 1 -i '{}' -c:v libx264 -t 5 -pix_fmt yuv420p -vf scale={}:{} ".format(video, width, height)+ url2
                cmd = "ffmpeg -loop 1 -i '{}' -t 5 -vf scale={}:{} ".format(video, width, height) + url2
                os.system(cmd)
                path_remover(video)
                video_list.append(url2)
            else:
                video_list.append(video)
    except ConnectionError:
        for i in video_list:
            path_remover(i)
        message = "broken url process could not be completed"
        return message
