  • FFmpeg with Pipe - how can I periodically grab real-time frames out of live streams in C# ?

    2 mars 2020, par BBy

    I am new to FFmpeg and C# and I want grab frames to do image processing with IP Camera.

    I have made the following C# class and I could get a single frame from IP Camera.

    class FFmpegHandler
    
    {
    
        public Process ffmpeg = new Process();
    
        public Image image;
    

    
        public Image init()
    
        {
    
            ffmpeg = new Process()
    
            {
    
                StartInfo =
    
                {
    
                    FileName = @"./ffmpeg/ffmpeg.exe",
    
                    //Arguments = "-i http://admin:@192.168.10.1/videostream.asf -an -f image2pipe -preset ultrafast -tune zerolatency -s 320x240 pipe:1", // Hangs
    
                    Arguments = "-i http://admin:@192.168.10.1/videostream.asf -vframes 1 -an -f image2pipe -preset ultrafast -tune zerolatency -s 320x240 pipe:1",
    
                    UseShellExecute = false,
    
                    RedirectStandardOutput = true,
    
                    RedirectStandardError = true,
    
                    CreateNoWindow = true,
    
                    WorkingDirectory = "./ffmpeg/"
    
                }
    
            };
    

    
            ffmpeg.EnableRaisingEvents = true;
    
            ffmpeg.Start();
    

    
            var stream = ffmpeg.StandardOutput.BaseStream;
    
            var img = Image.FromStream(stream);
    
            //ffmpeg.WaitForExit();
    

    
            return img;
    
        }
    
    }  

    The problem is that I want to grab real-time (latest) images when I request.

    If I run FFmpegHandler.init(), it will take 2 seconds to give me delayed image output.

    I have tried removing argument -vframes 1, then it will hang after image = Image.FromStream(stream) ;.

    When I check the ffmpeg output directly, it looks like ffmpeg is keep building the stream

    How can I grab the latest frames out of this live-stream image ? (OR is there a thread-safe way to clean the stream and only get the latest frame when I request ?)

  • Anomalie #4731 (Nouveau) : Invalid Date Time

    13 avril 2021, par Franck D

    Hello :)
    SPIP 3.3.0-dev GIT [master : 235be9bc]
    php 8 en local et chez ovh

    Sur un site vierge et neuf, quand je vais à la page ecrire/ ?exec=stats_visites&vue=table&graph=years
    Cela affiche "Invalid Date Time" voir copie d’écran

    Possible que cela soit logique car n’ayant aucun article, il s’agit d’un site vierge et neuf, mais dans le doute :)
