    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 (...)

  • Déploiements possibles

    31 janvier 2010, par

    Deux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
    L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

  • FFmpeg -ss parameter is the video duration, Output file is empty

    The main function is to obtain the corresponding video frame based on the input seconds.Before processing, the duration of the video will be obtained to determine whether the input is within the duration range of the video. If so, the corresponding instruction will be executed.

  • FFmpeg - record from stream terminating unexpectedly using kokorin/Jaffree ffmpeg wrapper for Java

    18 avril 2024, par pyrmon

    I am programming a Spring Boot Application using Maven and Java 21. I am trying to record a stream from a url and save it to a mkv file. I intend to do this with kokorin/Jaffree in version 2023.09.10. The recording seems to work ok, however longer videos are terminating unexpectedly. Sometimes after 5 minutes, other times an hour or even longer. Sometimes with Exit Code 0 and sometimes with 1.

    


    I have implemented the recording like this :

    


    @Override
    public void startRecording(RecordingSchedule recordingSchedule) {
        logger.info("Starting recording for schedule with filename {}", recordingSchedule.getFileName());

        String m3uUrl = recordingSchedule.getM3uUrl();
        LocalDateTime endTime = timeUtils.parseStringToLocalDateTime(recordingSchedule.getEndTime());
        LocalDateTime stopTime = endTime.plusSeconds(20);
        String timeToRecord = timeUtils.calculateTimeToRecord(stopTime);
        Path outputPath = Paths.get("/recordings/" + recordingSchedule.getFileName());

        try {
            FFmpeg.atPath()
                  .addInput(UrlInput.fromUrl(m3uUrl))
                  .addArgument("-xerror")
                  .addArguments("-reconnect", "5")
                  .addArguments("-reconnect_streamed", "5")
                  .addArguments("-reconnect_delay_max", "20")
                  .addArguments("-t", timeToRecord)
                  .addArguments("-c", "copy")
                  .addOutput(
                      UrlOutput.toPath(outputPath))
                  .setLogLevel(LogLevel.WARNING)
                  .execute();
            logger.info("Recording complete. Output file: {}", outputPath.toAbsolutePath());
        } catch (Exception e) {
            logger.error("Error recording M3U stream {}: {}", recordingSchedule.getFileName(), e.getMessage());
        }
    }


    


    And I am calling the method like this :
executorConfig.executorService().submit(() -> ffmpegService.startRecording(recording));

    


    Any ideas what I am doing wrong ?
Here are the log lines at the beginning and end of recording of the past two attempts :

    They were supposed to run nearly 3 hours and the other one over 3 hours. And with the timestamps you can see that they are not running nearly as long.
Thank you for your help !
