• FFMPEG concatinate audio file and add background music

  2 mai 2018, par Swetanka Jaiswal

  I want to concatenate 2 audio files and play the third audio in the background. I used below code

  ffmpeg -i 1.mp3 -i 2.mp3 -i background.mp3 -filter_complex "[0:0][1:0]concat=n=2:v=0:a=1,volume=1dB[a0] ;[2]volume=0.5dB[a1] ;[a0][a1]amerge[a]" -map "[a]" -strict -2 -y final.mp3

  suggested here ffmpeg : How to concat audio files and add background music in a single command ?

  But it is giving error "The following filters could not choose their formats : Parsed_amerge_3 Consider inserting the (a)format filter near their input or output."

  Please let me know what I’m doing wrong.
