• How to install package ffmpeg in google colab

  15 novembre 2022, par Nikhil Wagh

  I'm trying to use Google Colab to do something. Particularly I want to use ffmpeg package to create a video from a image.

  



  But ffmpeg doesn't seems to be working fine.

  



  The output of this (in the last block) was supposed to be 400 400 instead of 0 0

  



  frame_width = int(cap.get(3))
frame_height = int(cap.get(4))
print frame_width, frame_height


  



  The same code is working fine with Azure notebooks and also on my local machine.

  



  What can be the reason for it ? And how to rectify that ?

  


• Google Speech API - Is there a way to determine if the audio has human voice or not ?

  20 décembre 2019, par stupid_sma

  I am making an audio filtering application at work that reads over hundreds of audio files and filters them. So, if the audio has human voice in it, it will accept it and if it does not- it will delete the audio file.

  I am using ffmpeg to get the details of the audio and add other filters like size and duration and silence (though it is not very accurate in detecting silence for all audio files.)

  My company asked me to try the Google Cloud Speech API to detect if the audio has any human voice in it.

  So with this code, some audio files return a Transcript of spoken words in the audio file, but what I need is to determine if a human is speaking or not.

  I have considered using hark.js for it but there does not seem to be enough documentation and I am short on time !

  Ps. I am an intern and I’m just starting out with programming. I apologize if my question does not make sense or sounds dumb.
