  • 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 (...)

  • ffmpeg not working on Asp.net MVC

    9 avril 2015, par Faisal Mq

    I am using ffmpeg to extract thumbnails from video files and also to get their durations.
    The code works absolutely fine in Console Application, but when I use it on Asp.Net MVC 3, it does not work at all.

    I have placed ffmpeg.exe file on my application’s root folder and set its property "Copy to Output Directory" to "Copy Always"

    ffmpeg file gets placed in my application’s Bin folder after that I compile my project but it is not doing anything. It does not give me any error but also does not giving me my intended results, which are otherwise working absolutely fine in a Console application.

    [NOTE] In QuickWatch when I see the value for "output" on statement :

    string output = SROutput.ReadToEnd();

    ffmpeg shows me following output but this output does not include Duration info like it does in Console application.

            StreamReader SROutput = mProcess.StandardError;
    

    
            // Read all
    
            string output = SROutput.ReadToEnd();
    

    
            //get duration
    

    
            re = new System.Text.RegularExpressions.Regex("[D|d]uration:.((\\d|:|\\.)*)");
    
            m = re.Match(output);
    

    
            if (m.Success)
    
            {
    
                //Means the output has cantained the string "Duration"
    
                string temp = m.Groups[1].Value;
    
                string[] timepieces = temp.Split(new char[] { ':', '.' });
    
                if (timepieces.Length == 4)
    
                {
    

    
                    // Store duration
    
                    Duration = new TimeSpan(0, Convert.ToInt16(timepieces[0]), Convert.ToInt16(timepieces[1]), Convert.ToInt16(timepieces[2]), Convert.ToInt16(timepieces[3]));

            }
    

    
            mProcess.Close();
    

    
            return Duration;

    Please someone guide me where I am getting wrong.
