• Anomalie #2009 (Nouveau) : sqlite message utilisateur

  21 mars 2011, par Ben .

  Soit un site en sqlite. passons la base en lecture seule (444) . Lorsque l’on poste un commentaire sur le site public, cela ne fonctionne pas(c’est normal). Dans la log, on voit bien : "2 : attempt to write a readonly database -" par contre coté utilisateur/public : RIEN, pas de message. (...)

• Displaying progress while working on FFMpegConverter ?

  1er novembre 2017, par GreenRoof

  During a part of my project, I should download video data and audio data of a youtube link and merge them using NReco.VideoConverter. So this here is my code :

  public class Download {
  
      public NReco.VideoConverter.FFMpegConverter ffMpeg;
  
      public BackgroundWorker bgWorker;
  
  
  
      public Download (BackgroundWorker bgWorker) {
  
          this.BgWorker = BgWorker;
  
          var ffMpeg = new NReco.VideoConverter.FFMpegConverter();
  
          ffMpeg.ConvertProgress += (s, e) => ReportProgress(Convert.ToInt64(e.Processed.TotalSeconds), Convert.ToInt64(e.TotalDuration.TotalSeconds));
  
      }
  
  
  
      public MergeData() {
  
          // Video data and Audio data are downloaded to tempVidPath and tempAudPath.
  
          ffMpeg.Invoke(String.Format("-i \"{0}\" -i \"{1}\" -y -c copy \"{2}\"", tempVidPath, tempAudPath, targetPath));
  
      }
  
  
  
      public ReportProgress(long part, long total) {
  
          bgWorker.ReportProgress(0, new string[] {part.ToString(), total.ToString()});
  
      }
  
  }
  
  
  
  public partial class App : Form {
  
      //**omit
  
      public void Execution() {
  
          bgWorker = new BackgroundWorker(); // bgWorker is already defined in Designer class.
  
          bgWorker.WorkerReportsProgress = true;
  
  
  
          Download Dnld = new Download(bgWorker);
  
  
  
          bgWorker.ProgressChanged += (s, e) => {
  
              string[] arr = ((System.Collections.IEnumerable)e.UserState).Cast().Select(x => x.ToString()).ToArray();
  
              progBar.Maximum = Int64.Parse(arr[1]);
  
              progBar.Value = Int64.Parse(arr[0]);
  
          };
  
  
  
          bgWorker.DoWork += (s, e) => {
  
              Dnld.MergeData()
  
          }
  
  
  
      }
  
  }

  Here, I have no idea how to keep progBar to track the merging process while two files are being merged. Is there any method like WebClinet.DownloadFileAsync so I can get progress data from the thread ?

  ** I didn’t write unnecessary codes so codes may complicated and inefficient. But there are much more codes so please understand that problems. :)

• I want to convert my 3gp audio file to .wav formate

  11 mars 2020, par gowthami

  I want to convert my 3gp audio to .wav format. I used ffmpeg to convert that one. In that it is showing success not getting any error. But i am unable to get the final output file. Please help me to solve this issue.

  Here is my code.

  sampleDir = new File(Environment.getExternalStorageDirectory().getAbsolutePath(), "/OfficeRecordings/");
  
      if (!sampleDir.exists()) {
  
          sampleDir.mkdirs();
  
      }
  
  
  
      outputFile =  sampleDir+"/"+"sample_record.3gp";
  
  
  
      finalFile =  sampleDir+"/"+"final_record.wav"; 
  
  
  
      final String[] cmd = new String[]{"-y", "-i", outputFile, finalFile};
  
  
  
  
  
      execFFmpegBinary(cmd);
  
  
  
  
  
   private void execFFmpegBinary(final String[] command) {
  
  
  
          FFmpeg ffmpeg = FFmpeg.getInstance(this);
  
          try {
  
              FFmpeg.getInstance(MainActivity.this).loadBinary(new FFmpegLoadBinaryResponseHandler() {
  
                  @Override
  
                  public void onStart() {
  
                      Log.e("start",".......");
  
  
  
                  }
  
  
  
                  @Override
  
                  public void onSuccess() {
  
  
  
                      Log.e("success",".......");
  
                  }
  
  
  
                  @Override
  
                  public void onFailure() {
  
                      Log.e("fail",".......");
  
  
  
                  }
  
  
  
                  @Override
  
                  public void onFinish() {
  
                      Log.e("finish",".......");
  
  
  
                  }
  
              });
  
          } catch (FFmpegNotSupportedException e) {
  
              e.printStackTrace();
  
          }
