  • Les tâches Cron régulières de la ferme

    1 December 2010, by

    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 (...)

  • vaapi_h264: Add trivial support for low-power encoding

    vaapi_h264: Add trivial support for low-power encoding

    Experimental; requires Skylake and VAAPI 0.39.1 (not yet released).
    
Also increases the allowed range of the quality option - in low-power
    
mode, the Intel driver supports levels 1-8 (and 0 meaning default).

  • Understanding ffmpeg -benchmark results

    6 September 2022, by Ivy Growing

    Adding -benchmark flag to ffmpeg command resutls with addition of following 2 lines in the shell output:

    


    bench: utime=10.125s stime=4.234s rtime=5.606s
bench: maxrss=110080kB


    


    The maxrss serves to indicate the maximum RAM used during the ffmpeg execution. The utime, stime, rtime indicate accordingly:

    


      

    • user time;

      • 


    • system time;

      • 


    • real time.

      • 


    


    I tried to understand the meaning of these times from the source code and failed. Please, help.

    


      

    1. Which of these times indicate how much time was human waiting while the ffpmeg was processing the video?

      2. 


    2. Can this time be seen directly or it's a combination/calculation of these 3 parameters?

      3. 


    3. How it can be for certain videos utime > rtime and for others utime < rtime?

      4. 


    


  • Issues grabbing frames from an mp4 video using ffmpeg on java

    31 March 2015, by TamirW

    I am trying to grab a few frames from an mp4 video files using the ffmpeg library (java). Code snippet below.
    The issues I’m facing are:

    • In some (but not all) the videos I’m testing, I am getting the following warning when grabbing the frames: [swscaler @ 0x7fa642a53600] bad src image pointers
    • Sometimes, the frames I get are just blanks (black), sometimes they contain the last frame in the video (meaning that ALL the frames show the same image). Interestingly, when I’m not getting the above warning, the frames are just fine.

    Any clue or direction about how to debug/solve this issue would be greatly appreciated.

        FFmpegFrameGrabber g = new FFmpegFrameGrabber(video);
    
    List<bufferedimage> frames = new ArrayList<bufferedimage>();
    
    try {
    
        g.start();
    

    
        int i = 1, noOfFrames = g.getLengthInFrames();
    
        long FR = Math.round(g.getFrameRate());
    

    
        while (i &lt; noOfFrames) {
    
            g.setFrameNumber(i);
    
            IplImage img = g.grab();
    
            BufferedImage bimg = img.getBufferedImage();
    
            frames.add(bimg);
    

    
            i += FR;
    
        }
    
</bufferedimage></bufferedimage>
