• 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);

        }
        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.

• Sporadic "Error parsing Cues... Operation not permitted" errors when trying to generate a DASH manifest

  22 novembre 2023, par kshetline

  I have already-generated .webm audio and video files (1 audio, 3 video resolutions for each video I want to stream). The video has been generated not (directly) by ffmpeg, but HandbrakeCLI 1.7.0, with V9 encoding. The audio (which has never caused an error) is generated by ffmpeg using libvorbis.

  


  Most of the time ffmpeg (version 6.1) creates a manifest without any problem. Sporadically, however, "Error parsing Cues" comes up (frequently with the latest videos I've been trying to process) and I can't create a manifest. Since this is happening during an automated process to process many videos for streaming, the audio and video sources are being created exactly the same way whether ffmpeg succeeds or fails in generating a manifest, making this all the more confusing.

  


  The video files ffmpeg chokes on play perfectly well using VLC, and mediainfo doesn't show any problems with these files.

  


  Here's the way I've been (sometimes successfully, sometimes not) generating a manifest, with extra logging added :

  


  ffmpeg -v 9 -loglevel 99 \
  -f webm_dash_manifest -i '.\Sample Video.v480.webm' \
  -f webm_dash_manifest -i '.\Sample Video.v720.webm' \
  -f webm_dash_manifest -i '.\Sample Video.v1080.webm' \
  -f webm_dash_manifest -i '.\Sample Video.audio.webm' \
  -c copy -map 0 -map 1 -map 2 -map 3 \
  -f webm_dash_manifest -adaptation_sets "id=0,streams=0,1,2 id=1,streams=3" \
  '.\Sample Video.mpd'


  


  Here's the result when it fails :

  I don't know if I need different command line options, or whether this might be an ffmpeg or Handbrake bug. It has taken many, many hours to generate these video files (VP9 is painfully slow to encode), so I hate to do a lot of this over again, especially doing it again encoding the video with ffmpeg instead of Handbrake, as Handbrake is (oddly enough, considering it uses ffmpeg under the hood) noticeably faster.

  


  I have no idea what these "Cues" are that ffmpeg wants and can't parse, or how I would change them.

  


• The screen recorder utility has failed to store the actual screen recording iOS

  31 mai 2023, par manoj

  I am getting the below issue when I run my code to record the screen on failure.

  


  An unknown server-side error occurred while processing the command. Original error : The screen recorder utility has failed to store the actual screen recording at '/var/folders/js/h2_7h9bj1fj8cn19tqcm8hnw0000gn/T/202341-30610-87cfav.bsg2u/appium_3f7703.mp4'

  


  Note : This issue is occurring during the tearDown.

  


  the code is showing stop recording is failing and this issue is occurring for only one test class

  


  public static File screenRecording(String prefix) throws IOException {
        File classpathRoot = new File(System.getProperty("user.dir"));
        String screenRec = ((CanRecordScreen) driver).stopRecordingScreen();
        byte[] screenRecord = Base64.decodeBase64(screenRec);
        String destinationPath = classpathRoot.getAbsolutePath() + "/screenRecordings/" + driver.getPlatformName()
                + " Video " + prefix + " " + new Date() + ".mp4";
        Path filePath = Paths.get(destinationPath);
        Files.write(filePath, screenRecord);
        File recordedFile = FileUtils.getFile(String.valueOf(filePath));
        return recordedFile;
    }


  


  The same thing when I run it successfully is passing in other test
