I need to randomly insert an audio file (audio.mp3) into a .mp4 video with FFmpeg but I can't! The audio.mp3 file should be inserted into the video by cutting its sound and that anywhere in the video... Do you have an idea of the command to perform ?

I don't understand what you mean but it's pretty easy

Code:

ffmpeg \
    -i video1.mp4 -i audio1.mp3 \
    -c:v copy \
    -map 0:v -map 1:a \
    -y output.mp4

You maybe need to cut the audio in order to fit the video lenght?
get the video duration

Code:

ffprobe -i <file> -show_entries format=duration -v quiet -of csv="p=0"

and maybe trim it with sox

Code:

sox input output trim <seconds given by ffprobe>

No rocket science...
