• What is the best solution of motion interpolation by CPU ?

  31 mars 2022, par Stacker Dragon

  I've been using FFmpeg's "minterpolate" filter to implement motion interpolation to get a higher frame rate for a while. However, because "minterpolate" doesn't support hardware acceleration and multithread, it is very slow to finish that process, particularly on devices that only have CPU, which make the situation worse because I cannot use neural network such as DAIN(by SJTU).

  



  Thus, I would like to ask for some alternatives for "minterpolate" filter, which is supposed to be faster and has a decent quality.

  



  I knew SVP can do, but it is not open-sourced and therefore it cannot be integrated to other software.

  


• Split the video in 30 second equal parts in android using the Ffmpeg

  21 novembre 2019, par corgiwooer

  I am on a video editing project. In which I want to edit the video into 30 sec equal parts. Right now I am using the RangeSeekBar to get the starting and ending point which works perfectly fine. But now I want to split the video into equal parts but don’t know how to do it. This is what I tried

  private void executeCutVideoCommand(int startMs, int endMs) {
  
          File moviesDir = Environment.getExternalStoragePublicDirectory(
  
                  Environment.DIRECTORY_MOVIES
  
          );
  
  
  
          String filePrefix = "cut_video";
  
          String fileExtn = ".mp4";
  
          String yourRealPath = getPath(VideoCutterActivity.this, selectedVideoUri);
  
          File dest = new File(moviesDir, filePrefix + fileExtn);
  
          int fileNo = 0;
  
          while (dest.exists()) {
  
              fileNo++;
  
              dest = new File(moviesDir, filePrefix + fileNo + fileExtn);
  
          }
  
  
  
          filePath = dest.getAbsolutePath();
  
          String[] complexCommand = {"-ss", "" + startMs / 1000, "-y", "-i", yourRealPath, "-t", "" + (endMs - startMs) / 1000,"-vcodec", "mpeg4", "-b:v", "2097152", "-b:a", "48000", "-ac", "2", "-ar", "22050", filePath};
  
  
  
          execFFmpegBinary(complexCommand);
  
          MediaScannerConnection.scanFile(VideoCutterActivity.this,
  
                  new String[] { filePath },
  
                  null,
  
                  new MediaScannerConnection.OnScanCompletedListener() {
  
  
  
                      public void onScanCompleted(String path, Uri uri) {
  
  
  
                          Log.i("ExternalStorage", "Scanned " + path + ":");
  
                          Log.i("ExternalStorage", "-> uri=" + uri);
  
                      }
  
                  });
  
  
  
  
  
      }
  
  
  
      /**
  
       * Executing ffmpeg binary
  
       */
  
      private void execFFmpegBinary(final String[] command) {
  
          try {
  
              ffmpeg.execute(command, new ExecuteBinaryResponseHandler() {
  
                  @Override
  
                  public void onFailure(String s) {
  
                      Log.d(TAG, "FAILED with output : " + s);
  
                  }
  
  
  
                  @Override
  
                  public void onSuccess(String s) {
  
                      Log.d(TAG, "SUCCESS with output : " + s);
  
                          Intent intent = new Intent(VideoCutterActivity.this, PreviewActivity.class);
  
                          intent.putExtra(FILEPATH, filePath);
  
                          startActivity(intent);
  
                  }
  
  
  
                  @Override
  
                  public void onProgress(String s) {
  
                      progressDialog.setMessage("progress : " + s);
  
                  }
  
  
  
                  @Override
  
                  public void onStart() {
  
                      progressDialog.setMessage("Processing...");
  
                      progressDialog.show();
  
                  }
  
  
  
                  @Override
  
                  public void onFinish() {
  
                      progressDialog.dismiss();
  
  
  
  
  
                  }
  
              });
  
          } catch (FFmpegCommandAlreadyRunningException e) {
  
              // do nothing for now
  
          }
  
      }

  The above method takes the starting and the ending point and edits the video.

  I also tried to add for loop for this purpose but it didnt workout for me.

  cutVideo.setOnClickListener(new View.OnClickListener() {
  
              @Override
  
              public void onClick(View v) {
  
  
  
                  choice = 2;
  
  
  
                  if (selectedVideoUri != null) {
  
                      int start,end;
  
                      for (int i=0;i<=duration;i=i+30){
  
                          start=i;
  
                          end=start+30;
  
                          executeCutVideoCommand(start,end);
  
  
  
                      }
  
  //                    executeCutVideoCommand(rangeSeekBar.getSelectedMinValue().intValue() * 1000, rangeSeekBar.getSelectedMaxValue().intValue() * 1000);
  
  
  
                  } else
  
                      Snackbar.make(mainlayout, "Please upload a video", 4000).show();
  
              }
  
          });

  Please can anyone tell me how to do it. Help is much appreciated
