  • Les statuts des instances de mutualisation

    13 mars 2010, par

    Pour des raisons de compatibilité générale du plugin de gestion de mutualisations avec les fonctions originales de SPIP, les statuts des instances sont les mêmes que pour tout autre objets (articles...), seuls leurs noms dans l’interface change quelque peu.
    Les différents statuts possibles sont : prepa (demandé) qui correspond à une instance demandée par un utilisateur. Si le site a déjà été créé par le passé, il est passé en mode désactivé. publie (validé) qui correspond à une instance validée par un (...)

  • 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" (...)

  • FFMPEG : how can I properly add a text overlay to my video and save it to a thumbnail ?

    12 août 2013, par AWainb

    I have a ffmpeg command that goes to a url and successfully creates thumbnails at specified intervals. What I would like to do is add the time (eg : 03:45:20) to the bottom-left corner of the video in white text with a black shadow. I have seen a few examples online with drawtext but none of them seem to work with my current command :

    C:\ffmpeg\bin\ffmpeg.exe -ss 00:23:12 -i "http://myvideourl.com/videofile.mp4" -f mjpeg -vframes 1 -y C:\thumb2.jpg

    Can someone suggest how I can implement the correct drawtext filter with my current command so that it outputs the thumbnail with the duration stamped at the bottom-left corner ?

  • creating thumbnails from multiple videos

    28 septembre 2020, par blue

    I have multiple videos, and i want to create a thumbnail image for each video.i also want the image thumbnails to have the same names as the videos and have specific width/height.

    
Is it also possible to have ffmpeg create thumbnails with a specific aspect ratio and instead of stretching the video it could add black bars ?

    
Now i don't know a thing about how ffmpeg works so i looked up a tutorial online and configured it,tested out a simple script and it worked.

    
i found what the script i was looking for but i don't know a thing about bash scripts so it just throws an error and i don't how to figure it out.

    


    for f in *.mp4; do ffmpeg -i "$f" -ss 00:00:03 -vframes 1 -s 480x320 "${f%.mp4}.jpg"; done


    


  • How to use ffmpeg to merge the median of pixels in 2 videos

    24 avril 2020, par jocelyn

    I'm new to coding and ffmpeg so please go easy on me !

    



    I am trying to merge 2 videos (they are identical) using the median of the each pixel. I have to use ffmpeg to do this but am unable to find any information online.

    



    I have managed to merge 2 identical videos using the average of each pixel using the following command(I think at least, I'm not sure how to tell if this worked but the command didn't give any errors so I assume it did)
- "ffmpeg -i video1.avi -i video2.avi -filter_complex "blend=all_mode='average'" mergedvideo.avi"

    



    Can anyone help provide more information on how I can use ffmpeg to merge the videos using the median of each video pixel ?

    



    Thanks in advance !
