Automated installation script of MediaSPIP
25 avril 2011, parTo overcome the difficulties mainly due to the installation of server side software dependencies, an "all-in-one" installation script written in bash was created to facilitate this step on a server with a compatible Linux distribution.
You must have access to your server via SSH and a root account to use it, which will install the dependencies. Contact your provider if you do not have that.
The documentation of the use of this installation script is available here.

Les tâches Cron régulières de la ferme
1er décembre 2010, parLa 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 (...)

Trying to find a way to limit the number of List that can run at one time
14 mars 2024, par JakeMy application has a List of Tasks. Each Task launches a FFMPEG process that requires a lot of resources on my machine. At times, this list can contain 200+ processes to FFMPEG. While processing, my memory is at 99% and everything freezes up.


I need to limit the amount of processes that can run at one time. I have read a little about SemaphoreSlim ; however, I cannot wrap my mind around it's implementation.


Is this a solution for this particular problem and if so, any ideas on how to implement it in my code ?


Below is my code :


public async System.Threading.Tasks.Task GetVideoFiles()
{ 
 OpenFileDialog openFileDialog = new OpenFileDialog();
 openFileDialog.Multiselect = true;
 
 if (openFileDialog.ShowDialog() == true)
 {
 AllSplices.Clear();
 AllSplices = new ObservableCollection<splicemodel>();
 IsBusy = true;
 IsBusyMessage = "Extracting Metadata";
 IsBusyBackgroundVisible = "Visible";
 NotifyPropertyChanged(nameof(IsBusy));
 NotifyPropertyChanged(nameof(IsBusyMessage));
 NotifyPropertyChanged(nameof(IsBusyBackgroundVisible));
 metaTasks = new List>(); 
 extractFramesTask = new List();
 
 foreach (string file in openFileDialog.FileNames)
 {
 FileInfo fileInfo = new FileInfo(file);
 bool canAdd = true;
 var tempFileName = fileInfo.Name;
 
 foreach (var video in AllVideos)
 {
 if (file == video.VideoPath)
 {
 canAdd = false;
 break;
 }

 if (video.VideoName.Contains(tempFileName))
 {
 video.VideoName = "_" + video.VideoName; 
 } 
 }
 if (canAdd)
 { 
 metaTasks.Add(System.Threading.Tasks.Task.Run(() => ProcessMetaData(file))); 
 } 
 }
 var metaDataResults = await System.Threading.Tasks.Task.WhenAll(metaTasks); 
 
 foreach (var vid in metaDataResults)
 { 
 if(vid == null)
 {
 continue;
 }
 
 vid.IsNewVideo = true; 
 AllVideos.Add(vid);
 
 // This list of task launches up to 200 video processing processes to FFMPEG
 extractFramesTask.Add(System.Threading.Tasks.Task.Run(() => ExtractFrames(vid)));
 
 vid.IsProgressVisible = "Visible";
 TotalDuration += vid.VideoDuration;
 vid.NumberOfFrames = Convert.ToInt32(vid.VideoDuration.TotalSeconds * 30);
 _ = ReportProgress(vid);
 }
 
 IsBusyMessage = "Importing Frames";
 NotifyPropertyChanged(nameof(IsBusyMessage)); 
 await System.Threading.Tasks.Task.WhenAll(extractFramesTask); 
 }
</splicemodel>

Process won't stop
14 mai 2018, par Srdjan M.The process goes in infinite loop or it’s waiting something and I don’t know what. It won’t pass
WaitForExitmethode.FFmpeg :
-ss 0 -i output.mp4 -t 10 -an -y test.mp4C# Code :
using (Process process = new Process())
{
process.StartInfo.UseShellExecute = false;
process.StartInfo.RedirectStandardOutput = true;
process.StartInfo.RedirectStandardError = true;
process.StartInfo.FileName = FileName; // ffmpeg.exe
process.StartInfo.Arguments = Arguments; //-ss 0 -i output.mp4 -t 10 -an -y test.mp4
process.Start();
process.WaitForExit(); // stops here and waits
return process.StandardOutput.ReadToEnd();
}Edit :
Adding

27 juillet 2017, par Beni BlinchesI have a process which is a song that is playing audio from
youtubeusingffmpeg, and I want the song to stop when its done. I have this functionprivate Process CreateStream(string path)

};
Console.WriteLine(" ffmpeg is ready");
Program.current_s.Start();
