  • 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" (...)

  • MediaSPIP : Modification des droits de création d’objets et de publication définitive

    11 novembre 2010, par

    Par défaut, MediaSPIP permet de créer 5 types d’objets.
    Toujours par défaut les droits de création et de publication définitive de ces objets sont réservés aux administrateurs, mais ils sont bien entendu configurables par les webmestres.
    Ces droits sont ainsi bloqués pour plusieurs raisons : parce que le fait d’autoriser à publier doit être la volonté du webmestre pas de l’ensemble de la plateforme et donc ne pas être un choix par défaut ; parce qu’avoir un compte peut servir à autre choses également, (...)

  • Bitrate with mp3 - Can I put whatever I want ? [closed]

    5 juillet 2023, par AtyKlaxas

    I'm actually on a project to re-encode a large amount of audio files

    


    all over the internet I see people encoding in 320k, 196k, 128k

    


    If there is a rule for encoding values, what is it ?
Is there a reference table of encoding levels for mp3s ?
or i pur whatever i want ? (example 120k or 280k)

    


    I've tried asking ChatGPT
I expect to get these answers

    


    There's a reference table, you can't encode anything other than this : 320k, 256k, 196k, 128k (ect ...)

    


    There is no reference table, but the rules that are not written down and accepted by everyone are : (explanation)
and this gives us a list of bitrates 320k, 256k, (...)

    


    There are no rules at all, you can encode in any bitrate you like.
benchmarks such as 320k or 256k are only indicative and reflect nothing other than an arbitrary choice

    


  • FFMPEG SET ZxY width and height thumbnail while keeping aspect ratio with padding

    15 octobre 2014, par user3810748

    Ive been looking around stack overflow for code on how to make thumbnails using ffmpeg.
    But the two variations I find are either with -s 100x100 with a set frame - which ends in distorted thumbnails ; or the use of -vf 100 :-1, which only appropriately scales one side of the image - a problem for me since all thumbnails have to be of equal size ! is there a way to get the best of both worlds ?
    a set height/width with a constant ratio ? Like line it with black boxes or something ?

  • FFMPEG on Heroku exceeds memory quota in testing

    5 juillet 2022, par Patrick Vellia

    After following this tutorial, and getting it to work locally on my own development environment, before really getting my hands dirty and working deeper on my own project implementation, I decided to push it up to Heroku to test in a staging environment.

    


    I had to have Heroku add the FFMPEG build-pack and turn on the Redis Server for ActionCable to work.

    


    I didn't link the staging to a cloud storage bucket on Google or Amazon yet, just allowed it to upload directly to the dymo disk for testing. So it would go into the storage directory as it would in development for now.

    


    the test MOV file is 186 MB in size.

    


    The system uploaded the file fine.

    


    According to the logs, it then copied the file from storage to tmp as the tutorial has us do.

    


    Then it called streamio-ffmpeg's transcode method.

    


    At this point, Heroku forcibly kills the dymo because it far exceeds the memory quota.

    


    As this is a test environment, it's only on the free tier of Heroku.

    


    I'm thinking I won't be able to directly process video projects on Heroku itself, unless I'm wrong ? Would it be better to call an API like Cloud Functions or Amazon Lambda, or spin up a Compute Engine long enough to process the FFMPEG command ?
