  • Supporting all media types

    13 avril 2011, par

    Unlike most software and media-sharing platforms, MediaSPIP aims to manage as many different media types as possible. The following are just a few examples from an ever-expanding list of supported formats : images : png, gif, jpg, bmp and more audio : MP3, Ogg, Wav and more video : AVI, MP4, OGV, mpg, mov, wmv and more text, code and other data : OpenOffice, Microsoft Office (Word, PowerPoint, Excel), web (html, CSS), LaTeX, Google Earth and (...)

  • 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" (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • Summer Hacking 2011

    28 avril 2011, par Multimedia Mike — General

    I recently learned that iD — you know, the famed game company — has a series of summer tech camps :



    All I care to know is : Where were programs like these when I was 7-18 years old ? Born too early, I tell ya.

    That reminds me that the Google Summer of Code, 2011 Edition is getting underway soon. I guess it’s like summertime computer camp for college-aged students. FFmpeg / libav is once again a part of the program with 10 slots awarded by Google. Here are the students, projects, and mentors.

    Wish them luck.

  • Crop video by frame and save output as video

    3 avril 2018, par D_Corson

    I’m trying to resolve a question I had posted earlier (trying to only use FFMPEG) and am still stuck and hoping someone else has a solution.

    I have a video that I want to crop frame by frame with a varying locations to extract a region of interest. I can currently do this using moviepy which has been excellent, but I would like to try and solve this using only FFMPEG. The added constraints are that I would like to be able to crop the frame and put this in a new video without having to save the cropped images locally and compiling them.

    Thanks

  • How to create a video out of frames without saving it to disk using python ?

    6 septembre 2022, par brenodacosta

    I have a function that returns a frame as result. I wanted to know how to make a video out of a for-loop with this function without saving every frame and then creating the video.

    


    What I have from now is something similar to :

    


    import cv2
out = cv2.VideoWriter('video.mp4',cv2.VideoWriter_fourcc(*'DIVX'), 14.25,(500,258))
for frame in frames:
    img_result = MyImageTreatmentFunction(frame) # returns a numpy array image
    out.write(img_result)
out.release()


    


    Then the video will be created as video.mp4 and I can access it on memory. I'm asking myself if there's a way to have this video in a variable that I can easily convert to bytes later. My purpose for that is to send the video via HTTP post.

    


    I've looked on ffmpeg-python and opencv but I didn't find anything that applies to my case.
