    20 décembre 2018, par user2903753

    I want to replace part of the audio in one mp4 file with part of another mp3 file using ffmpeg.
    this is what I’m trying to do :

    ffmpeg -i 2009.mp4 -i birds.mp3 -filter_complex "[0:a]atrim=end=45,asetpts=PTS-STARTPTS[aud1];[1:a]atrim=0:18,asetpts=PTS-STARTPTS[aud2];  [0:a]atrim=start=63,asetpts=PTS-STARTPTS[aud3]; [aud1][aud2][aud3]concat=n=3:v=0:a=1[aout]"  -map 0:v -map "[aout]" -c:v copy   output.mp4

    it is giving me this error :

    [NULL @ 000000000596e020] Unable to find a suitable output format for
    ’ffmpeg’ ffmpeg : Invalid argument
