Complex filter with multiple maps

[eriknikulski]

I am mixing a video with audio and have this command that I am trying use with this library:

ffmpeg -i video.mp4 -i music.mp3 -filter_complex amix -map 0:v -map 0:a -map 1:a -shortest -c:v copy output.mp4

But I can't seem to get it work, mainly because of the multiple maps. What would be the preferred syntax?

I think to use amix you can do this

aout = ffmpeg.filter(
    [
        in0.audio,
        in1.audio,
    ],
    "amix",
)
