    Une fois le plugin activé, vous pouvez le configurer dans l’espace de configuration afin de modifier les droits de création / modification et de suppression des notes. Par défaut seuls les administrateurs du site peuvent ajouter des notes aux images.

    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.

    13 avril 2011, par

    MediaSPIP uses HTML5 video and audio tags to play multimedia files, taking advantage of the latest W3C innovations supported by modern browsers.
    The MediaSPIP player used has been created specifically for MediaSPIP and can be easily adapted to fit in with a specific theme.
    For older browsers the Flowplayer flash fallback is used.

  • mencoder. Encoding from multiple input image files compatible with web browser (No video support and MIME type) [duplicate]

    23 juin 2020, par iblasi

    I have multiple JPG files that I want to use to make a TimeLapse video compatible with the web browser to upload it on my web page.
Create a video with mencoder from multiple images is explained in some webpages such us here, that shows how to create a video.

    


    ls -Ltr my_Pics/*.jpg >files.txt
mencoder -nosound -ovc lavc -lavcopts vcodec=mpeg4 -o video.avi -mf type=jpeg:fps=4 mf://@files.txt


    


    The video is set with no sound and to have one picture every 250ms (4 fps).
These command lines create an AVI video that I can see correctly with the VLC video tool. However, if I try to open it in a web browser it shows an error :

    


    


    No Video with Supported Format and MIME type found

    


    


    So, based on other similar comments (as here), I tryed to use ffmpeg renaming all my files as ffmpeg requires a number serial format. But it happens the same, that I can see it in VLC but not in the browser.

    


    ffmpeg -r 4 -i ./output/%04d.jpg -vcodec libx264 video.mp4


    


    Based on research made on internet I am quite sure that it is due the the encoding and/or container. I tryed multiple options of codecs nd containers existing on documentation (here) but still not able to find a way to work.

    


    If, once I create the video, I use the VLC tool to manually convert the video to ".m4v" I was able to create a video that the web browser recognizes. But I would like to do it with command lines to automate it.

    


  • How to use ffmpeg in uwp ?

    22 avril 2022, par MrL

    I developed a software with electron. It needs ffmpeg, but when I package it into appx, I won't be able to use ffmpeg.

    


    let FFmpegPath = path.resolve(AppPath, "FFmpeg");
let FFMPEGPATH = path.resolve(FFmpegPath, "ffmpeg");
let FFPROBEPATH = path.resolve(FFmpegPath, "ffprobe");
let FFoption_V = '"'+FFPROBEPATH+'"' + " -i " +'"'+ path.normalize(PATH)+'"' + " -show_streams -select_streams v -of json";
EXEC_V = C_PRO.execSync(FFoption_V);


    


    This is the information I found, but it doesn't seem to work for electron :https://docs.microsoft.com/en-us/windows/apps/desktop/modernize/desktop-to-uwp-extensions

  • How do I extract video layers from an AVI ?

    14 janvier 2018, par Philosophistry

    I have a Fujifilm FinePix Real 3D W3, and it creates something Fujifilm calls 3D-AVI files. There are pograms to split these 3D-AVI files into separate left-and-right movies, but they involve using GUI-based software on Windows.

    I would rather use a command-line tool like ffmpeg, so that I can automate the process. Does anybody have any suggestions on how to go about doing this ?

    I’ve heard on forums that the 3D-AVI file is simply left and right AVIs on two video layers. I couldn’t see anything in the ffmpeg docs on how to extract these layers.
