  • 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 (...)

  • Why does javaFx run converted mp4 but not original ?

    20 février 2020, par brat

    Simply put, I have this issue where I have a mp4 file with a video. If I run it directly in the code posted here, the window opens but its white/blank. No movie showing.
    But if I run the original movie through ffmpeg it works.

    ffmpeg -i original.mp4 -s hd720 converted.mp4

    Note that Im converting from mp4 to mp4, I just change the size to hd720.
    So, the question is, why do I need to do that ?

    My code :

    package mypack;

    import javafx.application.Application;
    import javafx.scene.Group;
    import javafx.scene.Scene;
    import javafx.scene.layout.BorderPane;
    import javafx.scene.media.Media;
    import javafx.scene.media.MediaPlayer;
    import javafx.scene.media.MediaView;
    import javafx.stage.Stage;

    public class MyPlayer extends Application{

       public static void main(String[] args) {
           launch(args);
       }


       public void start(Stage primaryStage) throws Exception {
           BorderPane content = new BorderPane();

            Scene scene = new Scene(content, 540, 209);
            primaryStage.setScene(scene);
            primaryStage.setScene(scene);

            primaryStage.setTitle("Hello Media");

            String source;
            source = "file:///C:/Users/Noob/Desktop/Movies/original.mp4";
    //       source = "file:///C:/Users/Noob/Desktop/Movies/converted.mp4";


            Media media = new Media(source);

            MediaPlayer mediaPlayer = new MediaPlayer(media);
            mediaPlayer.setAutoPlay(true);

            MediaView mediaView = new MediaView(mediaPlayer);
            ((BorderPane) scene.getRoot()).getChildren().add(mediaView);
            primaryStage.show();

       }

    }

    For those audio/video afficionados/ffmpeg pros out there. This is what gets output from the original.

    Could it have to do with size ? To big ? Since it sayes 3840x2160 in the original ? And Im making it smaller with hd720 ?
    If so, I would expect at least a corner of the movie showing, instead of a totally blank window.
    Im new at this, so if you also give some good link to ffmpeg (excluding official manpages) and/or a good tutorial/info page on video formatting pointed towards beginners it would be much appreciated. My understanding this far is there are containers which hold streams and each stream can have different codecs depending on the container.

  • FFMPEG "Segmentation fault" with stream source and watermark

    4 mars 2020, par Magikey

    I use release : 4.2.2 (static) from "https://johnvansickle.com/ffmpeg/"

    Final code will be on "Amazon AWS lambda"

    Goal : use a url stream and add watermak

    Link to video : ​https://feoval.fr/519.mp4

    Link to Watermak : ​https://feoval.fr/watermark.png

    ./ffmpeg -i "https://feoval.fr/519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

    return "Segmentation fault"

    I have the same error on my computer and on AWS Lambda server

    ./ffmpeg -i "https://feoval.fr/519.mp4" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

    work (but not watermak)

    ./ffmpeg -i "./519.mp4" -i "./watermark.png" -filter_complex "overlay=W-w-10:H-h-10:format=rgb" -f "mp4" -movflags "frag_keyframe+empty_moov" -pix_fmt "yuv420p" test.mp4

    work (but not with stream)

  • FFMPEG profile-level-id size is invalid

    18 février 2020, par Mulham Aryan

    I’m trying to record a RTSP streaming from JVC KY-PZ 100.
    So for that i’m using ffmpeg with some parameters like segmentation, hls, ts, m3u8 etc ...
    i’m always getting an error The profile-level-id field size is invalid (41) and Error parsing AU headers

    This is the output of FFPROBE to debug the RTSP
