  • 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.

  • Publier sur MédiaSpip

    13 juin 2013

    Puis-je poster des contenus à partir d’une tablette Ipad ?
    Oui, si votre Médiaspip installé est à la version 0.2 ou supérieure. Contacter au besoin l’administrateur de votre MédiaSpip pour le savoir

  • Encoding and processing into web-friendly formats

    13 avril 2011, par

    MediaSPIP automatically converts uploaded files to internet-compatible formats.
    Video files are encoded in MP4, Ogv and WebM (supported by HTML5) and MP4 (supported by Flash).
    Audio files are encoded in MP3 and Ogg (supported by HTML5) and MP3 (supported by Flash).
    Where possible, text is analyzed in order to retrieve the data needed for search engine detection, and then exported as a series of image files.
    All uploaded files are stored online in their original format, so you can (...)

  • How do i simulate object-fit : fill with fluent-ffmpeg nodejs

    9 juillet 2023, par marvelMiles

    ffmpeg(input) .output(output) .outputOptions("-vf",scale=w=$1920:h=$1080) .outputOptions("-c:a", "copy") .on("end", () => { console.log("Video conversion completed"); }) .on("error", error => { console.error("Video conversion failed:", error); }) .on("progress", function(f) { console.log("...frames ", f.frames); }) .run()
code behave more like object-fit : contain than fill

    


  • How to create effect same video with FFmpeg

    29 juin 2023, par Sang Vo

    How to make a video from an image with a drag effect like this one in FFmpeg :

    


    https://www.youtube.com/watch?v=zC6qbpe3FyE&ab_channel=CloudMood


    


    I tried to zoom in zoom out effects but not the same with video

    


     ffmpeg -loop 1 -i photo.jpg -vf "zoompan=z='min(zoom+0.001,1.2)':x='if(gte(zoom,1.2),x+2,x-1)':y='if(gte(zoom,1.2),y+2,y-1)':d=10*25,framerate=25,scale=1920:1080" -c:v libx264 -t 10 -pix_fmt yuv420p -s 1920x1080 output.mp4


    


  • Code can not read property 1 of undefined [closed]

    25 mai 2023, par Jesse Copas

    I'm a very new programmer and am working on a Tdarr plugin in JS.
Everything works fine until a 4k file tries to get transcoded and it fails with this log

2023-05-24T19:09:54.907Z ZoBKWMMKG:Node\[hidden-hog\]:Worker\[tall-tuna\]:Error TypeError: Cannot read property '1' of undefined


    


    It's saying that it's unable to read property 1 of undefined and I'm looked and looked and looked and can't find what it is referring to. Hoping to get another set of eyes on it
The plugin Code is here

    Tried transcoding 4k files down to 1080p but it fails due to that undefined error. All Res 1080p and lower that I have tried work correctly

    


    EDIT : I used Console.log and got this back
