  • 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 (...)

  • Commandline video/image crossfading

    11 juin 2012, par tester

    I have a test.avi
    using ffmpeg or mencoder or some other commandline utility,
    I want to take splash.png put it at the beginning of the video,
    fade it out, show test.avi, then at the end of test.avi, fade splash.png back in.

    How would I go about doing this ?

  • Convert raw image using open-source library with permissive license

    30 août 2011, par Brian

    I need to convert a raw, rgb32-formatted image to a PNG with a library (written in, in order of preference, Java, C, C++) having a permissive (e.g. BSD or Apache) license.

    I'm able to convert the image using FFmpeg with this call :

    ffmpeg.exe -vframes 1 -vcodec rawvideo -f rawvideo -pix_fmt rgb32 -s 20x40 -i infile -f image2 -vcodec png out.png

    where 20x40 is the width by the height.

    But, sadly, I need to avoid FFmpeg due to its license.

    I've seen people speculate that libpng could do the job, but I'm skeptical given the documentation I've seen at the libpng site. Perhaps you'll give an example.

    I don't know what the rawvideo and rgb32 values mean to FFmpeg, so I asked this question.

    EDIT 1 : edited the ffmpeg call to show width x height.

  • How to get a loading return value

    5 septembre 2011, par anthonypliu

    I am trying to create a loading progress bar for my function :

    private string ConvertToFLV(string phyicalFilePath)
    
        {
    
            if (Path.GetExtension(phyicalFilePath).Equals(".flv")) return phyicalFilePath;
    

    
                var argument = string.Format(@"-i ""{0}"" -vcodec flv -f flv -r 29.97 -s 320x240 -aspect 4:3 -b 300k -g 160 -cmp dct  -subcmp dct  -mbd 2 -flags +aic+cbp+mv0+mv4 -trellis 1 -ac 1 -ar 22050 -ab 56k ""{1}""", phyicalFilePath, Path.ChangeExtension(phyicalFilePath, "flv"));
    
               // var argument = string.Format("-i {0} -crf 35.0 -vcodec libx264 -acodec libfaac -ar 48000 -ab 128k -coder 1 -flags +loop -cmp +chroma -partitions +parti4x4+partp8x8+partb8x8 -me_method hex -subq 6 -me_range 16 -g 250 -keyint_min 25 -sc_threshold 40 -i_qfactor 0.71 -b_strategy 1 -threads 0 {1}", phyicalFilePath, Path.ChangeExtension(phyicalFilePath, "mp4"));
    
                File.Delete(Path.ChangeExtension(phyicalFilePath, "flv"));
    

    
                ProcessStartInfo process = new ProcessStartInfo(ffmpegPhysicalPath, argument);
    
                Process proc = new Process();
    
                proc.StartInfo = process;
    
                proc.Start();
    
                proc.WaitForExit();
    

    
                return Path.ChangeExtension(phyicalFilePath, "flv");
    

    

    

    
        }

    Whent he command "proc.WaitForExit()" is invoked, I want to be able to return some type of load percentage. In the frontend I just have a gif loading image, but I want to be able to show progress on this, is there a way to do this ?
