  • 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 (...)

  • Installation en mode ferme

    4 février 2011, par

    Le mode ferme permet d’héberger plusieurs sites de type MediaSPIP en n’installant qu’une seule fois son noyau fonctionnel.
    C’est la méthode que nous utilisons sur cette même plateforme.
    L’utilisation en mode ferme nécessite de connaïtre un peu le mécanisme de SPIP contrairement à la version standalone qui ne nécessite pas réellement de connaissances spécifique puisque l’espace privé habituel de SPIP n’est plus utilisé.
    Dans un premier temps, vous devez avoir installé les mêmes fichiers que l’installation (...)

  • La sauvegarde automatique de canaux SPIP

    1er avril 2010, par

    Dans le cadre de la mise en place d’une plateforme ouverte, il est important pour les hébergeurs de pouvoir disposer de sauvegardes assez régulières pour parer à tout problème éventuel.
    Pour réaliser cette tâche on se base sur deux plugins SPIP : Saveauto qui permet une sauvegarde régulière de la base de donnée sous la forme d’un dump mysql (utilisable dans phpmyadmin) mes_fichiers_2 qui permet de réaliser une archive au format zip des données importantes du site (les documents, les éléments (...)

  • FFmpeg error : Unable to find a suitable output format for ''

    11 juillet 2020, par Benjamin Basmaci

    I'm new to ffmpeg as well as Android programming. I'm trying to load a video from a URL and crop it with ffmpeg. I want to save that video to a file. This is the command I found online :

    


    "-i " + videoUrl + "-filter:v crop=240:120:100:100 -c:a copy test.mp4"


    


    I have tried it and got the error Unable to find a suitable output format for ''

    


    So I tried to narrow the possible cause down and tried these commands as well :

    


    "-i " + videoUrl + " -c:v copy -c:a copy test.mp4"
"-i " + videoUrl + " -c:v copy test.mp4"
"-i " + videoUrl + " -c:a copy test.mp4"
"-i " + videoUrl + " test.mp4"


    


    So with that last one I basically boiled it down to the bare minimum of what a comment needs, as far as I know. But still, same result.

    


    All of them give me the same error. Here is the full output I got via FFmpeg.getLatestOutput()

    Why does ffmpeg assume that I have given it no output format and what I need to do to make this work ?

    


    I'm using implementation 'com.arthenica:mobile-ffmpeg-full:4.2'.

    


  • FFMPEG images to video outputs junk

    15 décembre 2019, par GreatCorn

    I’m very new to using FFMPEG and I’m trying to make an image sequence into a video. However, none of my attempts were succesful. I first tried 825x480 .pngs which resulted in video output and then 512x512 .jpgs, pretty much the same result. I tried a few codes like ffmpeg -framerate 24 -i img%03d.png output.mp4, ffmpeg -r 1/5 -framerate 24 -i img%03d.png -c:v libx264 -vf -pix_fmt yuv420p output.mp4 and etc. I just don’t really understand what I’m supposed to do to prevent this.

  • FFMPEG does not produce output a valid mp4 when called from Java

    13 décembre 2019, par VincBreaker

    I am merging an image with an audio file into a mp4-video using the ffmpeg-command :

    ffmpeg -y -r 30 -loop 1 -i <path></path>to/image.png> -i <path></path>to/audio.aac> -shortest -acodec copy -vcodec libx264 <path></path>to/output.mp4>

    To call this command from Java I’m using this code :

    ProcessBuilder builder = new ProcessBuilder("ffmpeg", "-y", "-r",
                       String.valueOf(generalConfig.getOutputFPS()), "-loop", "1", "-i", pictureFile,
                       "-i", transspoken.getVoiceFile(), "-shortest", "-acodec", "copy", "-vcodec", "libx264",
                       snippetOut);
    builder.redirectOutput(new File(getTMPName() + ".txt"));
    builder.redirectError(new File(getTMPName() + ".txt"));
    builder.redirectErrorStream(true);

    LogUtils.debug("FFMPEG-Render", String.join(" ", builder.command()));
    try {
       Process p = builder.start();
       p.waitFor();
    } catch (IOException | InterruptedException e) {
       e.printStackTrace();
    }

    This code runs without problem on my local machine running Ubuntu 18.04 Desktop and OpenJDK 11.0.4. However, when run on a Ubuntu 18.04 Server droplet, running the same OpenJDK-Version, the code results in a corrupted output. Strangely, there is absolutely no problem when I ssh into the server and call exactly the same command to generate the mp4 file. So I am in a the really strange situation where :

    1. The command works fine when called automatically on my local machine.
    2. The command works fine when called manually on the server.
    3. The command does not work when called automatically on the server.

    Output of the automated FFMPEG call on the server :

    At first I thought that the java program is not properly waiting for FFMpeg to finish thereby causing the corrupted output but some time measurements made me somewhat confident that that is not the cause of this bug.
