  • 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 (...)

  • Introducing WebM, an open web media project

    19 mai 2010, par noreply@blogger.com (christosap)

    A key factor in the web’s success is that its core technologies such as HTML, HTTP, TCP/IP, etc. are open and freely implementable. Though video is also now core to the web experience, there is unfortunately no open and free video format that is on par with the leading commercial choices. To that end, we are excited to introduce WebM, a broadly-backed community effort to develop a world-class media format for the open web.

    WebM includes :

    • VP8, a high-quality video codec we are releasing today under a BSD-style, royalty-free license
    • Vorbis, an already open source and broadly implemented audio codec
    • a container format based on a subset of the Matroska media container

    The team that created VP8 have been pioneers in video codec development for over a decade. VP8 delivers high quality video while efficiently adapting to the varying processing and bandwidth conditions found on today’s broad range of web-connected devices. VP8’s efficient bandwidth usage will mean lower serving costs for content publishers and high quality video for end-users. The codec’s relative simplicity makes it easy to integrate into existing environments and requires less manual tuning to produce high quality results. These existing attributes and the rapid innovation we expect through the open-development process make VP8 well suited for the unique requirements of video on the web.

    A developer preview of WebM and VP8, including source code, specs, and encoding tools is available today at www.webmproject.org.

    We want to thank the many industry leaders and web community members who are collaborating on the development of WebM and integrating it into their products. Check out what Mozilla, Opera, Google Chrome, Adobe, and many others below have to say about the importance of WebM to the future of web video.

  • ffmpeg : Pipe input error

    1er septembre 2012, par Amit Khanna

    I'm facing an issue while working with ffmpeg when input and output are pipes. Though Output pipe is working fine, piping the input is causing some error.

    I tried to convert mp4 video to flv using the following command and it worked fine :

    $ ffmpeg  -i video-2012-04-26-19-48-40.mp4 -ar 44100 -ab 96 -f flv pipe:1 | cat> videoname.flv

    It worked fine and gave the following output :

  • Program hangs while using ffprobe on file with teletext subtitles

    6 août 2012, par Jon

    Having a problem running ffprobe on an MKV file that contains teletext subtitles. Code is in a C# library and works fine for other MKV files.

    Running the latest :

    ffprobe -v
    

    
ffprobe version N-42347-g299387e Copyright (c) 2007-2012 the FFmpeg developers
    
  built on Jul  8 2012 15:44:54 with gcc 4.7.1

    Code :

    string args = string.Format("-show_format -show_streams \"{0}\"", FileName);
    

    
Process p = new Process();
    
p.StartInfo = new ProcessStartInfo(FFPROBE_PATH);
    
p.StartInfo.Arguments = args;
    
p.StartInfo.CreateNoWindow = true;
    
p.StartInfo.RedirectStandardOutput = true;
    
p.StartInfo.RedirectStandardError = true;
    
p.StartInfo.UseShellExecute = false;
    
p.StartInfo.WorkingDirectory = System.IO.Directory.GetCurrentDirectory();
    
p.Start();
    

    
while (!p.HasExited)
    
{
    
    System.Threading.Thread.Sleep(100);
    
}
    

    
string output = p.StandardOutput.ReadToEnd().Replace("\r\n", "\n");

    The filename has a UNC path - tried using the FileName parameter but got an error, hence passing the filename via the arguments.

    If I run the following commandline :

    ffprobe -show_format -show_streams "\192.168.10.1\content\Breakfast At Tiffany's sample preview.mkv"

    I get the following output (note the errors - "Unsupported codec with id ...") :

    ffprobe -show_format -show_streams "\\192.168.10.1\content\Breakfast At Tiffany's sample preview.mkv"

    My problem is, the process appears to hang. I took out the 'CreateNoWindow' option and, of course, I get a big blank window onscreen that normally just flashs by on a normal file. With the teletext subtitle file however, it persists. If I manually close it, the program continues and I seem to get the output I want.

    So my question is, how can I debug this further, to find out why this is hanging and how to handle the error (or simply ignore it) and continue ?
