  • ffmpeg's strange behaviour-Conversion started when I close my application

    16 décembre 2013, par m.qayyum

    I'm using ffmpeg in my application to rotate video, but problem is that when I start conversion ffmpeg only shows it's version information and not start the actual conversion, but when I close my application ffmpeg process remains in Running Processes in Taskbar and start to convert the file.

    ffmpeg output
    enter image description here

    Here is my code, please tell me where i'm doing it wrong.

    void ConvertVideo(object[] arr) {
    

    
    string Argument = (string)arr[0];
    
    string OutputFolder = (string)arr[1];
    
    string ConvertedFile = (string)arr[2];
    

    

    
    UpdateStatus("Converting! Please wait...");
    
    ffmpeg = new Process();
    
    ffmpeg.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
    
    ffmpeg.StartInfo.FileName = "ffmpeg.exe";
    
    ffmpeg.StartInfo.UseShellExecute = false;
    
    ffmpeg.StartInfo.RedirectStandardError = true;
    
    ffmpeg.StartInfo.RedirectStandardOutput = true;
    
    ffmpeg.StartInfo.CreateNoWindow = true;
    
    ffmpeg.StartInfo.Arguments = Argument;
    
    ffmpeg.Start();
    
    myStreamReader = ffmpeg.StandardError;
    
    outputLine = myStreamReader.ReadLine();
    
    UpdateRTB(outputLine);//Write line to ritchtextbox
    
    do
    
    {
    
        if (outputLine.Contains("muxing overhead"))
    
        {
    
            UpdateStatus("Muxing video");
    
        }
    

    
        if (outputLine.StartsWith("frame"))
    
        {
    
            UpdateStatus("Converting video");
    
        }
    
    }
    
    while (!(ffmpeg.HasExited & (string.Compare(outputLine, "") == 0 | outputLine == null)));
    
    ffmpeg.Close();
    
    myStreamReader.Close();
    
    UpdateStatus("Convertion completed successfully");

  • How to speed up video conversion

    9 mai 2016, par Arheisel

    I’m currently working in a proyect that involves converting large series of .jpg (>6000) into video format. These frames (320x240) are stored in folders at a rate of 2.5fps. Generating a couple of folders every hour that need to be converted ASAP.

    For now i’ve tried copying the folder to a ram disk and using avconv wich takes about a minute.

    Here is my command :

    avconv -threads auto -y -r 2.51 -i %03d-capture.jpg -s 320x240 -r 25 video.mpeg

    could ffmpeg work faster ?
    is there a way to speed it up ?
    wich video format take less time to convert to ?
