1. Add MobileFFmpeg dependency from jcenter()

   dependencies {`
       implementation 'com.arthenica:mobile-ffmpeg-full:2.1'
   }
   

2. Execute commands.

   import com.arthenica.mobileffmpeg.FFmpeg;
   
   int rc = FFmpeg.execute("-i file1.mp4 -c:v mpeg4 file2.mp4");
   
   if (rc == RETURN_CODE_SUCCESS) {
       Log.i(Config.TAG, "Command execution completed successfully.");
   } else if (rc == RETURN_CODE_CANCEL) {
       Log.i(Config.TAG, "Command execution cancelled by user.");
   } else {
       Log.i(Config.TAG, String.format("Command execution failed with rc=%d.", rc));
   }
   

3. Stop an ongoing operation.

   FFmpeg.cancel();
   

4. Enable log callback.

   Config.enableLogCallback(new LogCallback() {
       public void apply(LogMessage message) {
           Log.d(Config.TAG, message.getText());
       }
   });
   

5. Enable statistics callback.

   Config.enableStatisticsCallback(new StatisticsCallback() {
       public void apply(Statistics newStatistics) {
           Log.d(Config.TAG, String.format("frame: %d, time: %d", newStatistics.getVideoFrameNumber(), newStatistics.getTime()));
       }
   });
   

6. Set log level.

   Config.setLogLevel(Level.AV_LOG_FATAL);
   

7. Register custom fonts directory.
