• Is it possible to change volume with no reencode with ffmpeg ?

  30 juin 2023, par John Smith

  I just had this question because I used the following command with ffmpeg :

  



  ffmpeg -i input.wav -filter:a "volume=0.2" output.wav


  



  Following the documentation here : https://trac.ffmpeg.org/wiki/AudioVolume

  



  However, when I created the new file, the output was half the size of the input and the bitrate of the audio track was reduced as well.

  



  So my questions are :

  



  

  1. Is the bitrate supposed to decrease with decreasing and increasing volume like so ?

  


  2. Is it possible to change volume without reencoding with ffmpeg ?

  


  


• Create a looped video with countdown

  13 décembre 2016, par Enrico Deleo

  Something maybe challenging here :
  I want to stream (via rtmp) a video with a fixed image and a countdown applied on it. I know I can create a slideshow with even audio background with ffmtp (http://trac.ffmpeg.org/wiki/Create%20a%20video%20slideshow%20from%20images) but I’m wondering if I can loop it AND apply an overlay with the countdown to a given date.

  Any ideas ?
