  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.
    Le super Cron (gestion_mutu_super_cron)
    Cette tâche, planifiée chaque minute, a pour simple effet d’appeler le Cron de l’ensemble des instances de la mutualisation régulièrement. Couplée avec un Cron système sur le site central de la mutualisation, cela permet de simplement générer des visites régulières sur les différents sites et éviter que les tâches des sites peu visités soient trop (...)

  • Taille des images et des logos définissables

    9 février 2011, par

    Dans beaucoup d’endroits du site, logos et images sont redimensionnées pour correspondre aux emplacements définis par les thèmes. L’ensemble des ces tailles pouvant changer d’un thème à un autre peuvent être définies directement dans le thème et éviter ainsi à l’utilisateur de devoir les configurer manuellement après avoir changé l’apparence de son site.
    Ces tailles d’images sont également disponibles dans la configuration spécifique de MediaSPIP Core. La taille maximale du logo du site en pixels, on permet (...)

  • Wildcard for sequential images

    16 septembre 2013, par abalter

    I'm trying to animate a series of jpg files using avconv. Based on numerous examples, I'm trying using %d.jpg to specify the files. Or %05d.jpg. However, I'm getting :

    avconv -i %d.jpg a.avi
    
avconv version 0.8.3-4:0.8.3-0ubuntu0.12.04.1, Copyright (c) 2000-2012 the Libav developers built on Jun 12 2012 16:37:58 with gcc 4.6.3
    
%d.jpg: No such file or directory

    Here is a snip of my directory listing :

    10380.jpg
    
10390.jpg
    
10400.jpg
    
1040.jpg
    
10410.jpg
    
10420.jpg
    
10430.jpg
    
10440.jpg

    There are jpegs from 00000.jpg to 14400.jpg

    I don't really understand that wildcard system, but that is what is in examples.

    (note : I tagged it ffmpeg because a tag for avconv does not exist, and avconv supersedes ffmpeg)

    Update
    I'm updating the question based on the answer below by @av501.

    To begin with, I have a list of png files with sequential ordering by 10. They have text preceding a 5 digit integer. For example :

    SkinMattekNutrient_py_00000.png
    
SkinMattekNutrient_py_00010.png
    
SkinMattekNutrient_py_00020.png
    
...
    
SkinMattekNutrient_py_10440.png

    What would be the way to batch convert these to jpg ? I tried

    convert ...
    
SkinMattekNutrient_py_%05d.png %05d.jpg

    and

    convert ...
    
SkinMattekNutrient_py_%5d.png %5d.jpg

    But I get :

    convert SkinMattekNutrient_py_%05d.png %05d.jpg
    
convert: missing an image filename `%05d.jpg' @ error/convert.c/ConvertImageCommand/3011.

  • Diamond Rio Artifacts

    30 août 2012, par Multimedia Mike — Multimedia History

    Remember the Diamond Rio PMP300 ? It’s credited with being the very first portable MP3 player, released all the way back in 1998 (I say ‘credited’ because I visited an audio museum once which exhibited a Toshiba MP3 player from 1997). I recently rescued a pristine set of Rio artifacts from a recycle pile.



    I wondered if I should scan the manual for posterity. However, a Google search indicates that a proper PDF (loaded with pleas to not illegally copy music) isn’t very difficult to come by. Here are the other items that came with the unit :

    Ah, more memories (of dialup internet) : A tie-in with another Diamond product, this time a modem which claims to enable the user to download songs at up to 112 kilobits per second. I wonder if that was really possible. I remember that 56k modems were a stretch and 33.6k was the best that most users could hope for.

    There is also a separate piece of paper that advises the buyer that the parallel port adapter might look a bit different than what is seen in the printed copy. Imagine the age of downloading to your MP3 player via parallel port while pulling down new songs via dialup internet.

    The artifacts also included not one, but two CD-ROMs :



    Click for larger image

    One is a driver and software disc, so no big surprise there. The other has a selection of MP3 files for your shiny new MP3 player. I’m wondering if these should be proactively preserved. I was going to process the files’ metadata and publish it here, for the benefit of search engines. However, while metadata is present, the files don’t conform to any metadata format that FFmpeg/Libav recognize. The files mention Brava Software Inc. in their metadata sections. Still, individual filenames at the end of this post.

    Leftovers :
    A few other miscellaneous multimedia acquisitions :



    I still want to study all of these old multimedia creation programs in depth some day. Theatrix Hollywood is a creative writing game, Wikipedia alleges (I’m a bit rigid with my exact definition of what constitutes a game). Here is an example movie output from this software. Meanwhile, the Mad Dog Multimedia CD-ROM apparently came packaged with a 56X CD-ROM drive (roughly the pinnacle of CD-ROM speeds). I found it has some version of Sonic Foundry’s ACID software, thus making good on the “applications” claim on the CD-ROM copy.
