• Splitting audio tracks with incorrect length - FFMPEG

  26 mars 2018, par channae

  Version : com.writingminds:FFmpegAndroid:0.3.2

  I have an audio file with length 43 seconds. And I wrote an algorithm to split at each 10 seconds mark where a word ends (For this I used IBM Watson to get ending timestamp). So cropping duration is always around 10 seconds to 11 seconds. Of course except the 5th one. I have printed my commands so that you will understand my use-case better.

  System.out: Split Command: -y -i /storage/emulated/0/AudioClipsForSpeakerRecognition/merge.wav -ss 00:00:00.000 -codec copy -t 00:00:10.010 /storage/emulated/0/AudioClipsForSpeakerRecognition/segment_1.wav
  
  
  
  System.out: Split Command: -y -i /storage/emulated/0/AudioClipsForSpeakerRecognition/merge.wav -ss 00:00:10.010 -codec copy -t 00:00:21.090 /storage/emulated/0/AudioClipsForSpeakerRecognition/segment_2.wav
  
  
  
  System.out: Split Command: -y -i /storage/emulated/0/AudioClipsForSpeakerRecognition/merge.wav -ss 00:00:21.090 -codec copy -t 00:00:30.480 /storage/emulated/0/AudioClipsForSpeakerRecognition/segment_3.wav
  
  
  
  System.out: Split Command: -y -i /storage/emulated/0/AudioClipsForSpeakerRecognition/merge.wav -ss 00:00:30.480 -codec copy -t 00:00:40.120 /storage/emulated/0/AudioClipsForSpeakerRecognition/segment_4.wav
  
  
  
  System.out: Split Command: -y -i /storage/emulated/0/AudioClipsForSpeakerRecognition/merge.wav -ss 00:00:40.120 -codec copy -t 00:00:43.000 /storage/emulated/0/AudioClipsForSpeakerRecognition/segment_5.wav

  However when playing all cropped audio files I noticed segment_1 is about 10 seconds and segment_2 is about 20 seconds etc. Therefore some of the audio parts belong to segment_1 also available in segment 2 etc etc. Why is this happening ?

  Appreciate your response.

• looking for the right regex expression to pick some specific sentences from a file using java regex

  26 novembre 2014, par sachh_ke_nasdiik

  I am writing a program in java that records the screen.
  it is actually something that uses the ffmpeg tool
  with a simple GUI.
  what I actually need is a way to grab from the following file :

  1. ffmpeg version N-57367-g2f31b73 Copyright (c) 2000-2013 the FFmpeg developers

  21. dummy : Immediate exit requested

  only the sentences between the quotation marks,
  those that describes the different devices,
  that shows up at the end of the file,
  ignoring of course the line numbering, that does not appear in the
  output file, but inserted here for better fluency.
  does anyone have any ideas how to work it out using java regex ?
  assuming I am using an enhanced for loop over a string array
  checking each line for its contents.
