  • 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.

  • Swift : How can I generate Mp4 video from programmaticall output ? [closed]

    21 août 2020, par Mount Ain

    This question is specifically to Swift programming language for Linux & macOS platforms.To understanding the concept, I used Swift programming language. But not depend on Swift programming language. C or C++ is also good to me.

    


    I can generate JPEG image from NSView by using NSBitmapImageRep. But Linux I don't what I want to do. So, the first thing I need to know is the step to generate JPEG image by programmatically without using the NSView. I really don't know How hard it is. But I want to learn how it's work. I feel It's the way to fill the color into pixels one by one to combine a Image. But I don't know How to do in programming. I knew the same way is used in videos by packing the series of image with audio & subtitle & other meta info.

    


    If you ask about compression, I really want to know How Twitter & YouTube compressing uploaded videos without loss of quality.

    


    So what is the concept,

    


      

    1. To generate a JPEG image by programmatically without using NSView ?

      2. 


    2. To generate MPEG-4 video by group of JPEG images ?

      3. 


    


    Thanking in advance...

    I did a very simple python video chat that from OpenCV takes the frames from webcam and send them through udp socket.
If I want to use h265 and ffmpeg-python, what should I do ? Is there some example somewhere ?
