  • 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 (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • Configuration spécifique d’Apache

    4 février 2011, par

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • Combining background video, audio, text and image to create a new vertical 1080*1920p video using ffmpeg

    3 mars 2023, par Arya Anish

    How can I combine background video, text and image to create a new vertical 1080*1920p video using ffmpeg. The text is contained in a sentences.txt file and each sentence is seperated by a line. Each senetence should stay on the video for n seconds. (for eg. 2 seconds) I tried using ChatGPT but, I quit, I spent 2 hours debugging and I don't want to do so for another 10 hrs.

    


  • 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"

  • FFMPEG - Merge Video-A with audio of of Video-B in a single command ? [duplicate]

    16 avril 2019, par R. Kohlisch

    This question already has an answer here :

    I would like to use the video of video A, and put the audio of video B on top. How would I do this with ffmpeg in the command line ? I have found tutorials to do this with extracting the audio first to a wav file, but I was wondering whether it’s possible to do this in a single command ? and without transcoding everything again ?

    edit : both files are .mp4 files and both contain video & audio. both files are of equal length.
