    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • 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 (...)

  • Converting video files from mp4 to webM for playing using Media Source Extensions

    19 octobre 2018, par raul

    I’m currently trying to implement a video player using Media Source Extensions. Currently just a very simple proof of concept, following a tutorial I found here.

    I cloned their repo with all source code from github here and am testing the implementation on Chromium and Firefox with various video files.

    Everything worked well with the example webm files in the repo for both browsers.

    Next I tried to convert a video I downloaded from some random site using ffmpeg and mse-tools to "align the clusters" of the webm file using the following commands :

    ffmpeg -i randomvideo.mp4 -c:v libvpx -c:a libvorbis output.webm
    
mse_webm_remuxer output.webm aligned.webm

    Again, all was well on both browsers.

    Finally, I wanted to convert a very simple animation I created in blender (rendered with h264 in mp4).

    I tried converting the resulting file using the same process as above and the file played normally on firefox, but did not load on chromium.

    I assume I am commiting some error when converting the file, but inspecting the attributes of the final file with vlc and ffprobe, I could not find any obvious problems.

    Any ideas as to what I am doing wrong ?

    One final test I did was to go to this site to get some sample webm files.

    I downloaded the "Big Buck Bunny Trailer in WebM" and "Elephants Dream as WebM File".

    Both files worked in firefox, but the "Elephants Dream" file would not play in chromium.

    I am on a linux machine (Arch Linux distro) with the following versions of the browsers :

    Chromium Version 69.0.3497.100 (Official Build) Arch Linux (64-bit)

    Firefox 62.0.3 (64-bit)

    I have shared the file I created from the blender animation (very small - only 36 KB) on google drive here in case anyone wants to check it out.

  • ffmpeg doesn't render video

    12 mars 2021, par mnbvfkd58

    I have a script which merges videos together with ffmpeg, when I try to do so, I always
get this error

    


    ffmpeg._run.Error: ffmpeg error

    


    I have tried setting arguments : capture_stdout=True, capture_stderr=True
and --encoder_codec mp4v

    


    here's the full line of code that gives me this error
ffmpeg.output(audioo, videoo, rastas).global_args("-y","--encoder_codec mp4v").run(capture_stdout=True, capture_stderr=True)

    


    How do I fix it ?

    


    I'm doing this on an ubuntu vps 20.10
