• ffmpeg dont work in php shell_exec("ffmpeg -i $movie $pic &")

  26 septembre 2016, par josef

  I’m running the following script without any problems :

  <?php
  
  echo $video  = dirname(__FILE__)."\\MOVIES\\1.mp4";
  
  echo "<br />";
  
  echo $pic  = dirname(__FILE__)."\\PICTURES\\1.jpg";
  
  echo shell_exec("ffmpeg -i  $video  $pic &amp;");

  But when I run this one i get nothing :

  echo shell_exec("ffmpeg -i  C:\xampp\htdocs\Video-share-script\MOVIES\1.mp4  C:\xampp\htdocs\Video-share-script\PICTURES\1.jpg &");

  the value of $video is C :\xampp\htdocs\Video-share-script\MOVIES\1.mp4
  and $pic is C :\xampp\htdocs\Video-share-script\PICTURES\1.jpg
  thank you

• Grabbing a single image from a MS VS .NET 6.0 C# WPF process always returns the same image

  12 mai 2023, par Wolfgang Kurz

  I am trying to develop a MS VS .NET 6.0 C# WPF application to digitize my Super 8 cine films. To grab the frames of the film I want to use FFMPEG because Accord.NET6.0 DirectShow does not work under MS VS 2022 .
I use
FFmpeg 64-bit static Windows build from www.gyan.dev
Version : 2022-09-29-git-8089fe072e-full_build-www.gyan.dev

  


  FFMPEG is invoked from a Process in ma application whicch sets the process FFMPEG start parameters. The webcam parameter is "USB Webcam" ( digital Celestron handheld microscope connected via USB - is DirectShow compatible )
The video resolution parameter "camRes" is "1280x960"

  


  public void UpdateImage(string aString)
    {
        string startPath = "C:" + MainWindow.bSl + "ffmpeg" + MainWindow.bSl + "bin" + MainWindow.bSl + "ffmpeg.exe ";

        MainWindow.aResult = "";
        System.Drawing.Bitmap result;
        ProcessStartInfo psi;
        psi = new ProcessStartInfo();
        psi.FileName = startPath;
        string targPath;
        psi.Arguments = "-f dshow -video_size" + MainWindow.dQuote + webCam + MainWindow.dQuote +
             " -framerate 10  -i video=" + MainWindow.dQuote + camRes + MainWindow.dQuote +
            " -frames:v 1 test%3d.bmp -update 1";
        string errors = "";
        string results = "";
        psi.CreateNoWindow = false;
        psi.RedirectStandardOutput = true;
        psi.RedirectStandardError = true;
        psi.WindowStyle = ProcessWindowStyle.Normal;
        psi.WorkingDirectory = "C:" + MainWindow.bSl + "ffmpeg" + MainWindow.bSl + "bin" + MainWindow.bSl;

        using (Process theProcess = new Process())
        {
            theProcess.StartInfo = psi;
            theProcess.Start();

            theProcess.WaitForExit();
            while (theProcess.HasExited == false)
            {
                Thread.Sleep(50);
            }
            Thread.Sleep(50);

            try
            {
                if (File.Exists(pathCI) == true)
                {
                    DefineImage.ffmpegRes = new Bitmap(pathCI);
                    MainWindow.actMWInstance.UpdateMessage(DateTime.Now +
                        "- Old image disposed, new image grabbed");
                    File.Delete(pathCI);
                }
            }
            catch (System.Exception ex)
            {
                MainWindow.actMWInstance.UpdateMessage(DateTime.Now + "Image grabbing failed");
            }
            theProcess.Close();
            theProcess.Dispose();
        }

        if (aString.Length == 0)
        {
            File.Delete(pathCI);
            MainWindow.actMWInstance.DoMove("200", "0", true);
        }
        if (ffmpegRes != null)
        {
            BitmapSource aBMPSrc = BitmapConversion.ToWpfBitmap(ffmpegRes);
            IMGFrame.Source = aBMPSrc;
        }
        Show();
    }

  My problem now is, when I try to refresh the image in the DefineDialog window, I always get the same image although the film has been moved by one frame.

  


  Is the first image cached by FFMPEG and always used again with the provided parameters.

  


  How to force FFMPEG to replace the image with a new one.

  


  ---

  


  -----------------------------------------------------------------------+this is additional information to the question.
I have managed to grab the film frame but still get always the same image during a session :*

  


  

  


  It is obvious that the cine film frame has been successfully grabbbed.
The next step should be to work at the image ( correct brightness contrast, gama and colors) and then store the evaluated correction values that have later to be applied to the frames during a batch process, which automatically transports the film, grabs the frames and corrects the colors and then stores the frames as consecutively numbered images which than can be used to generate a video with FFMPEG :

  


  Now the problem I cannot overcome :

  


  In the definition dialog there are 2 buttons ( Refresh and New Image). The intension is to reread / regrab a frame, if the current frame is not optimal to evaluate the correction values.

  


  Whenever I click one of the buttons FFMPEG seems to grab an image, but FFMPEG provides always the same (identcial to the first already available image) to the caller ( a .NET C# Process in my proggram).

  


  The output stream is a single jpg image ( test%04d.jpg ) in a specified target library . Here follows the generated output which seem to be OK according to my knowledge.

  


  I want to ask all interested persons to look over this provided information - may be someone has an idea, what causes the fact, that FFMPEG 6.0 van Neumann always delivers the first image grabbed. in a session.
It seems that there is something cached and reused over and over again.

• h264 extracting frames works only on certain operating system / ffmpeg version

  15 juin 2018, par J. S.

  I have received parsed h264 data from my phone, and I am trying to extract frames from the data.

  I used the following ffmpeg command lines :

  ffmpeg -i temp.h264 -ss 5 -pix_fmt yuv420p -vframes 1 foo.yuv
  
  
  
  ffmpeg -s 1280:720 -pix_fmt yuv420p -i foo.yuv output.jpg

  This results in the right output image on Ubuntu (KDE neon User Edition 5.12) with ffmpeg version 2.8.14.

  However, it does not work on macOS High Sierra (10.13.4) with ffmpeg version 4.0 and instead shows an output message :

  Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)

  I am not sure whether this is a mere ffmpeg version-related issue or not because as an experiment, when I converted the h264 data into mp4 format and played it on macOS High Sierra, the video sometimes shows a sequence of black distorted image (screenshot), and other times, a normal video.

  If I play that same video on Ubuntu (KDE neon User Edition 5.12), the video plays perfectly.

  I don’t understand why this problem would occur, and whether this has to do with OS or ffmpeg library version.
  What would be some good ways to approach this problem ? Thanks.
