• Installing ffmpeg in Ubuntu by using Chef fails by error of yasm version

  23 décembre 2014, par ironsand

  I want to install ffmpeg in Ubuntu14.04 by using chef.

  This is my config files for it.

  Berksfile

  source "https://api.berkshelf.com"
  
  cookbook 'apt'
  
  cookbook 'ffmpeg'

  nodes/ubuntu.json

  {
  
      "run_list": [
  
          "apt",
  
          "ffmpeg"
  
      ]
  
  }

  Then run knife solo cook ubuntu. It ends up with a error :

  STDOUT: Found no assembler
  
  Minimum version is yasm-1.2.0

  I understand the error. probably if I install yasm-1.2.0 manually, then the error will be fixed.

  But I want to install only by using chef. What can I do to solve the problem ?

• 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.
