  • 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" (...)

  • Submit enhancements and plugins

    13 avril 2011

    If you have developed a new extension to add one or more useful features to MediaSPIP, let us know and its integration into the core MedisSPIP functionality will be considered.
    You can use the development discussion list to request for help with creating a plugin. As MediaSPIP is based on SPIP - or you can use the SPIP discussion list SPIP-Zone.

  • Python get Audio/Video frames separately from video file

    3 juillet 2016, par AlvaroAV

    What i’m trying to do :

    Hi !

    I’m trying to store the Video and Audio information from a video file. I would like to store video frames and audio frames separately in different variables.

    My intention is to manage video/files and do some actions with the audio and video frame list, but to do what I’m plannign to do I need to store this audio/video frames separately. I’ve read a lot of questions in StackOverflow about python and audio/video managing.

    Most people recommend to use OpenCV or ffmpeg to manage videos. I saw some scripts using these libraries to get video(only video) frames, but none of them are getting audio, most of them are just getting video frames and save them as RGB images. I also check some scripts where people get audio frames from a mp3 file, but I’m not sure if you can do that in a video file

    Most important thing to me is to know the best way to manage video and audio separately. I’m not looking for people to do my code, just asking to point me in a good direction.

    One of the things I’m trying to do is to send this information via socket, but as I said I need the audio and video frames to be in separated variables (yes, i’m wondering about an stream app, but that’s not the only thing I’m trying to do)

    I know I should give more information, and maybe show some code, but I don’t have any concret code I tried some things, but I’ve never been capable to separate audio and video. I know that each format has his own encryption, and at the end I decided to use "mp4" as video format but I don’t know neither if this is the best format for what I’m trying to do.

    Resume :

    Is openCV the best way to manage video and audio separately ?

    Wich is the easiest way to separate video and audio frames ? Is it possible ?

    Wich is the best documentation I should read to learn about video/audio management ?

    I would like to do the things with my own code, and use in the less way possible openCV or other libraries.

    My "basic" idea is to get a "list" of audio and video frames, and then I would like to do some operations, but right now I can’t find the best way for me to manage a vide using python. I even wonder if could be possible to manage a video as raw data

    I need to know wich is the best library to manage videos using python, for me the best library, will be the one that allows me to manage the videos more "freely"

    I’ve already checked :

    I’ve read too many questions on this theme, the most recent are :

  • video streaming - mp4 file (x264) - and skip to location

    14 mars 2011, par Raoul

    Previously I was using apache to serve .flv files which an embedded player on an intranet page was playing.

    Is it possible to stream mp4 files (x264 encoded) in a similar manner ? Are there any open source scripts/solutions for doing proper streaming (e.g. people can skip to skip to a part of the video without having to download the parts they've skiped over) ?

    If anyone is doing someting similar I'd love to hear from them

    Thanks
