  • Creating farms of unique websites

    13 avril 2011, par

    MediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.
    This allows (among other things) : implementation costs to be shared between several different projects / individuals rapid deployment of multiple unique sites creation of groups of like-minded sites, making it possible to browse media in a more controlled and selective environment than the major "open" (...)

  • 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) (...)

  • FFmpeg - What muxer do i need to save an AAC audio stream

    1er mars 2017, par David Barishev

    I’m developing Android application, and im using ffmpeg for conversion of files.
    I want my binary file to be as slim as possible since i don’t have many input formats and output formats, and my operation is quite basic.And of course not to bloat the APK.

    In my program ffmpeg receives a file, and copys the audio stream (-acodec copy), the audio stream will always be aac (mp4a). What i need is to save the stream to file.
    My command looks like this : ffmpeg -i {Input} -vn -acodec copy output.aac.

    What muxer do i need to for muxing aac to file ? I have tried flv,mp3,mov but i always get
    Unable to find a suitable output format for 'output.aac', so these options are wrong.
    I don’t need an encoder for stream copy btw.

    Side note : this command work flawlessly on full installation of ffmpeg , but I don’t know which muxer it uses. If there is a way to output the muxer it uses from regular ffmpeg run, it would work too.

  • Record screen and save to .mp4 video

    10 avril 2023, par Freddy J

    I have created an animation in Pyglet and I want to save this animation as a video retaining the same quality as the Pyglet window. I attempt to use imageio and FFMPEG with Pyglet. See relevant snippets below.

    


    import numpy as np
import pyglet
import imageio.v2 as iio

writer = iio.get_writer("out.mp4")

@window.event
def on_draw():
    # Draw
    # ...

    # Capture frame
    color_buffer = pyglet.image.get_buffer_manager().get_color_buffer()
    image_data = buffer.get_image_data()
    buffer = image_data.get_data("RGBA", image_data.pitch)

    # 4 channels: RGBA
    frame = np.frombuffer(buffer).reshape((image_data.height, image_data.width, 4))
    writer.append_data(frame)


    


    Problem :

    


    buffer has expected size of window width * window height * 4.
    
However, np.frombuffer(buffer) has size buffer size / 8. I do not know why. I expect the size to be equal. Hence, the program fails at the reshape step.

    arm : vp9itxfm : Avoid .irp when it doesn’t save any lines

    This makes it more readable.
