• Android FFMPEG : images to mp4 video converting

  19 juillet 2017, par Giorgi Asaturyan

  I have tried many possible command line options with ffmpeg, however not getting this to work. Heres is my command file generator method :

   private String[] generateCommandFile() {
  
      ArrayList<string> cmd = new ArrayList&lt;>();
  
  
  
      cmd.add("-y");
  
      cmd.add("-f");
  
      cmd.add("concat");
  
      cmd.add("-safe");
  
      cmd.add("0");
  
      cmd.add("-i");
  
      String picturesTextFile = generateMergingFilesTexts();
  
      if (picturesTextFile == null) {
  
          return null;
  
      }
  
      cmd.add(picturesTextFile);
  
      cmd.add("-i");
  
      String audioTextFile;
  
      if (numberOfAudioFiles > 1) {
  
          audioTextFile = generateAudioFilesTexts();
  
      } else {
  
          audioTextFile = getAudioFilePath(audioRecordingFileName + Integer.toString(1));
  
      }
  
  
  
      cmd.add(audioTextFile);
  
  
  
      cmd.add("-vsync");
  
      cmd.add("vfr");
  
      cmd.add("-pix_fmt");
  
      cmd.add("yuv420p");
  
  
  
      String currentDateTimeString = new SimpleDateFormat("dd MMMM yyyy", Locale.US).format(Calendar.getInstance().getTime());
  
      File dirOut = new File(this.getExternalFilesDir(null), "D:T:" + currentDateTimeString);
  
      if (!dirOut.exists()) {
  
          dirOut.mkdirs();
  
      }
  
      directoryPath = dirOut.getAbsolutePath();
  
      File fileOut = new File(dirOut, "T__" + Long.toString(totalTime) + "__P__" + Integer.toString(picturesModelInfo.getNumberOfShots()) + ".mp4");
  
      cmd.add(fileOut.getAbsolutePath());
  
      Log.d(TAG, "Saving File At " + fileOut.getAbsolutePath());
  
  
  
      String[] finalCommand = new String[cmd.size()];
  
  
  
      for (int i = 0; i &lt; cmd.size(); i++) {
  
          finalCommand[i] = cmd.get(i);
  
      }
  
  
  
      String finalString = "";
  
      for (String command : finalCommand) {
  
          finalString += command;
  
      }
  
  
  
      Log.d(TAG, "Final Command Is " + finalString);
  
      return finalCommand;
  
  }
  
  </string>

  and here is my Final Command

  -y-fconcat-safe0-i/storage/emulated/0/Android/data/com.essentialsln.memtalk/files/pictures_merging.txt-i/storage/emulated/0/Android/data/com.essentialsln.memtalk/files/AudioRecording1.3gp-vsyncvfr-pix_fmtyuv420p/storage/emulated/0/Android/data/com.essentialsln.memtalk/files/D:T:19 July 2017/T__2__P__3.mp4

  The main problem is that video not playing in android default player - displays ("Cannot Play video, unsupported file type"), but it works with VLC program. ))

  Anu Suggestions ?

  Thanks

• FFMPEG - No such filter 'minterpolate'

  18 juillet 2017, par Eduardo Perez

  So, I am trying to run a command in FFMPEG to do motion interpolation, and this is what happens.

  ffmpeg -i '드래곤빌리지 에피소드 영상 2화 (공식)-CYOxGwLy4mk.mkv' -filter "minterpolate='fps=60'" 60fps.mp4

  First I run the above command to encode a video, and I get the following output :
