  • Les tâches Cron régulières de la ferme

    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 (...)

  • How can I resize an overlay image with ffmpeg ?

    28 novembre 2020, par Andrei Dascalu

    I am trying to add an overlay to a video using the following command

    


    ffmpeg -y -i "$videoPath" -i "$overlayPath" -filter_complex "[0:v] [1:v] overlay=$overlayPosition" -pix_fmt yuv420p -c:a copy "$outputPath" 


    


    However, I would like to be able to resize the overlay I am about to apply to some arbitrary resolution (no care for keeping proportions). However, although I followed a couple of similar solutions from SO (like FFMPEG - How to resize an image overlay ?), I am not quite sute about the meaning of the parameters or what I need to add it in my case.

    


    I would need to add something like (?)

    


    [1:v]scale=360:360[z] [1:v]overlay=$overlayPosition[z]


    


    This doesn't seem to work so I'm not sure what I should be aiming for.

    


    I would appreciate any assistance, perhaps with some explanation.

    


    Thanks !

    


  • ffmpeg c# Windows forms

    7 février 2017, par TODO

    I’m fairly new to windows forms and ffmpeg (unity background).

    I’m trying to get a button click on a windows form to take a png sequence, and convert it to an mp4 with ffmpeg.

            Process ffmpeg = new Process();
    

    
        ffmpeg.StartInfo.FileName = Path.Combine(Environment.CurrentDirectory, @"c:\test\ffmpeg.exe");
    

    
        ffmpeg.StartInfo.Arguments = "-framerate 25 -i 0001_IMG%03d.JPG -c:v libx264 -preset ultrafast -crf 0 -vf scale=-2:1080 -pix_fmt yuv420p temp.mp4";
    

    
        ffmpeg.Start();

    I have no problem running the same ffmpeg command from cmd, or from within a c++ console application I experimented with Using system("")

    I’ve been stuck on this for a little longer than I care to admit, and have tried searching for answers, but am still learning as i go.

    Any help would be much appreciated.

  • Timeout on a Java OutputStream.write()

    17 avril 2021, par user416983

    The OutputStream is created by Process.getOutputStream(). I want to the OutputStream.write() to support a predefined timeout : whenever the OutputStream.write()/OutputStream.flush() doesn't return in a given time threshold, I would be signaled somehow.

    


    The underlying OS is Linux, I don't care about other systems.
The Process is an ffmpeg instance which is used to publish a video stream continuously.

    


    Note, I need the write()/flush() function call to return or be interrupted in a given time threshold, not the process to terminate in a given time threshold.
