• How to split video or audio by silent parts

  18 mars 2016, par TermiT

  I need to automatically split video of a speech by words, so every word is a separate video file. Do you know any ways to do this ?

  My plan was to detect silent parts and use them as words separators. But i didn’t find any tool to do this and looks like ffmpeg is not the right tool for that.

• Fingerprint vs transcribing, what is the best approach to identify an audio sample inside another longer audio [closed]

  28 mai 2024, par Bernard Wiesner

  I am trying to detect a shorter version of a spoken audio sample inside a longer audio (full version). The shorter audio should be the same or very similar to the one inside the longer version. I also need to have a rough estimate of the timestamp where the audio sample was found.

  What I have researched so far :

  


  1. fingerprints

  


  

  • Using chromaprint extract the fingerprints from both audio files and store them in a DB, then compare them and find matches.

  


  


  2. transcribing

  


  

  • Use a transcriber such as whisper, to transcribe both audio files and store the text in a DB, then compare them and find matches.

  


  


  I am trying to figure out the simplest solution for this, while still being performant and not too CPU/GPU intensive. My questions are :

  


  

  1. Which one would you chose for simplest, cost effective solution ?

  


  2. Which one would consume more disk space ?

  


  3. Which one would perform better, in terms of searching/matching using SQL ?

  


  


  FYI : If there are any other alternatives to those I listed please let me know.

  


• Bash Script to convert all flv file in a directory to mp3

  11 août 2014, par UnbrandedTech

  This is my code so far.

  #!/bin/bash
  
  #James Kenaley
  
  #Flv to Mp3 directory converter
  
  
  
  find /home/downloads -iname "*.flv" | \
  
  while read I;
  
  do
  
      `ffmpeg -i ${I} -acodec copy  ${I/%.flv/.mp3}`
  
      echo "$I has been converted"
  
  done

  but its picking up white spaces in the names of the flv files and throws a error saying its not in the directory. how do make it use the whole file name and not the just the first word before the space ?
