• IOException on watermarking video on Android

  19 septembre 2016, par Stefan Ionescu

  I am trying to programmatically watermark a video in Android using WritingMinds’ Ffmpeg library from Github :

  https://github.com/WritingMinds/ffmpeg-android-java

  I did all they said in their documentation and imported the library in Android Studio.

  Still, it gives me an IOExeption with "No such file or directory".

  CODE

  public class MainActivity extends Activity {
  
  
  
  Button btn;
  
  Context context;
  
  
  
  String str;
  
  
  
  @Override
  
  protected void onCreate(Bundle savedInstanceState) {
  
  super.onCreate(savedInstanceState);
  
  setContentView(R.layout.activity_main);
  
  
  
  btn = (Button) findViewById(R.id.button);
  
  
  
  context = this;
  
  
  
  str = "ffmpeg -i /storage/extSdCard/DCIM/Camera/video.avi -i /storage/extSdCard/DCIM/Camera/logo.png -filter_complex 'overlay=10:main_h overlay_h-10' /storage/extSdCard/DCIM/Camera/watermarked.avi";
  
  
  
  btn.setOnClickListener(new View.OnClickListener() {
  
  @Override
  
  public void onClick(View view) {
  
  
  
  doFfmpeg(str.split(" "));
  
  
  
      }
  
    });
  
   }
  
  }
  
  
  
  public void doFfmpeg(String[] loc){
  
  
  
  FFmpeg ffmpeg = FFmpeg.getInstance(context);
  
  
  
  try {
  
  // to execute "ffmpeg -version" command you just need to pass "-version"
  
  ffmpeg.execute(loc, new ExecuteBinaryResponseHandler() {
  
  
  
  @Override
  
  public void onStart() {
  
  }
  
  
  
  @Override
  
  public void onProgress(String message) {
  
  }
  
  
  
  @Override
  
  public void onFailure(String message) {
  
  }
  
  
  
  @Override
  
  public void onSuccess(String message) {
  
  
  
  Toast.makeText(getApplicationContext(), "Success !", Toast.LENGTH_LONG).show();
  
  
  
  }
  
  
  
  @Override
  
  public void onFinish() {
  
    }
  
   });
  
  } catch (FFmpegCommandAlreadyRunningException e) {
  
  // Handle if FFmpeg is already running
  
  } catch (Exception e){
  
  
  
  }
  
  
  
   }
  
  }

• streaming iOS simulator screen using idb and ffmpeg [closed]

  26 janvier 2024, par user12857692

  I'm trying to use idb to streaming iOS simulator screen with this command

  


  idb video-stream --fps 30 --format h264 --udid XXXXXX | ffmpeg  -f h264 -i pipe: -listen 1 -f mjpeg http://0.0.0.0:9000

  


  And I use this mjpeg player to view : https://gist.github.com/codebrainz/eeeeead894e8bdff059b

  


  However, its all black.

  


  I've tried my other mjpeg sources, and they all display properly.

  


  What's wrong with idb/ffmpeg ?

  


  ffmpeg version : 6.1.1

  


• How to get offset from audio

  24 avril 2014, par Dhaval

  I need to insert another audio on specific offset (where space existed in audio track).

  So, For that, i need to fetch offset of each space from audio and then apply some ffmpeg/sox command to insert another aduio on that offset.

  Please share me some command to fetch the offset for space
  first so, later, i could mix the another audio on same offset.

  Please suggest your view/command or any library.

  I think, it would be possible in FFMPEG OR SOX.

  Updated :
  I have two audio files.
  In which one audio files contains some songs but, there are some space at some interval. These space should be fill by another audio.

  example :
  Audio 1 - song - audio has space at 5 places.

  audio 2 - a people name audio.

  output - audio one should fill up the all 5 places by aduio 2.

  Thanks
