  • Amélioration de la version de base

    13 septembre 2013

    Jolie sélection multiple
    Le plugin Chosen permet d’améliorer l’ergonomie des champs de sélection multiple. Voir les deux images suivantes pour comparer.
    Il suffit pour cela d’activer le plugin Chosen (Configuration générale du site > Gestion des plugins), puis de configurer le plugin (Les squelettes > Chosen) en activant l’utilisation de Chosen dans le site public et en spécifiant les éléments de formulaires à améliorer, par exemple select[multiple] pour les listes à sélection multiple (...)

  • Le plugin : Podcasts.

    14 juillet 2010, par

    Le problème du podcasting est à nouveau un problème révélateur de la normalisation des transports de données sur Internet.
    Deux formats intéressants existent : Celui développé par Apple, très axé sur l’utilisation d’iTunes dont la SPEC est ici ; Le format "Media RSS Module" qui est plus "libre" notamment soutenu par Yahoo et le logiciel Miro ;
    Types de fichiers supportés dans les flux
    Le format d’Apple n’autorise que les formats suivants dans ses flux : .mp3 audio/mpeg .m4a audio/x-m4a .mp4 (...)

  • Emballe médias : à quoi cela sert ?

    4 février 2011, par

    Ce plugin vise à gérer des sites de mise en ligne de documents de tous types.
    Il crée des "médias", à savoir : un "média" est un article au sens SPIP créé automatiquement lors du téléversement d’un document qu’il soit audio, vidéo, image ou textuel ; un seul document ne peut être lié à un article dit "média" ;

  • machine hangs during ffmpeg command execution [closed]

    15 décembre 2023, par Tejas

    I'm running this ffmpeg command that does multiple trims on input video and concats those trims to generate output.

    


    ffmpeg -i https://d8r14y803bnlk.cloudfront.net/usetldr/2736037/u/796/st/5a919413ff884892bbfffcd0671687a9/p/67c1a16438bf4bb78b785557f4cef7ef/OJx1SIKTNbbGHmQfKT4C_render.mp4 -filter_complex "[0:v:0]trim=start=0.0:end=4.289,setpts=PTS-STARTPTS,format=yuva420p[0v];[0:v:0]trim=start=4.84:end=1034.7,setpts=PTS-STARTPTS,format=yuva420p[1v];[0v][1v]concat=n=2:v=1:a=0" -crf 18 -an -preset ultrafast -y /tmp/8TZeqB3Z6h.mp4


    


    This command works fine on my M1 mac but hangs EC2 instances (c5.4xlarge).

    


    I'm using ffmpeg version 6.1-static https://johnvansickle.com/ffmpeg/  Copyright (c) 2000-2023 the FFmpeg developers built with gcc 8 (Debian 8.3.0-6) on EC2.

    


    Any idea why this could be happening ?

    


  • ffmpeg - converting one audio track of a multi-track mp4

    30 décembre 2023, par Shaun.M

    I'm having a few mp4 with two audio tracks,
an english one in aac and a french one in dts.

    


    Now I want to convert only the french dts to eac3 with a single ffmpeg command.

    


    I use

    


    ffmpeg -hide_banner -i input.mp4 ^
             -map_metadata -1 ^
             -map 0:0 -c:v copy ^
             -map 0:1 -c:a copy ^
             -map 0:2 -c:a eac3 -b:a 1536k ^
             -metadata:s:a:0 language=eng ^
             -metadata:s:a:0 title="Stereo" ^
             -metadata:s:a:1 language=fra ^
             -metadata:s:a:1 title="Stereo" ^
output.mp4


    


    This works quite nice, but it converts both audio tracks to eac3, instead of leaving the first one untouched ...
What's wrong in the command ?

  • 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

    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

    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
