• FFMpeg Add Background Music to Video

  10 juillet 2021, par Hossein

  I wanna add a background music on my video.
I tried this command

  


  ffmpeg -i video.mkv -i audio.m4a -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -ac 2 output.mkv


  


  It worked but when music ended, My Video Sound end too.
I want to repeate the background music until video end.
And if I can change background music volume it will be awosome

  


• FFMpeg - add background music

  20 mars 2016, par jacky brown

  here is what i have :
  input1.avi - video that contain sounds.
  input2.avi - video that doesn’t contain sounds.
  music.mp3 - audio file.

  i want to add background music(music.mp3 file) to the video.

  C:\input1.avi -i C:\music.mp3 -shortest -c:v copy -c:a copy C:\output1.avi

  then output1.avi is the same as input1 - movie with sounds but without the background music (music.mp3)

  when i try to use the other file (video without sounds) :

  C:\input2.avi -i C:\music.mp3 -shortest -c:v copy -c:a copy C:\output2.avi

  then output2.avi is the same as input2 + it have the background music.

  so why input1 does not contain the background music ???
  and how can i decrease or increase the volume of music.mp3 file ?

  thanks.
