FFMpeg Concat mp4 files without encoding

ffmpeg -i [url removed, login to view] -i [url removed, login to view] -i [url removed, login to view] -y -filter_complex concat=n=3:v=1:a=1 -movflags +faststart -threads 0 -preset slow -f mp4 [url removed, login to view]

Error: ffmpeg exited with code 1: Error configuring complex filters. Invalid argument


I am running this command from node.js usinf fluent-ffmpeg and getting this error.

The 3 files are from deferent sources, but all encoded with same parameters:

'-movflags +faststart',

'-threads 0',

'-preset slow',

'-s hd480',

'-profile:v high',

'-r 25',

'-tune film',

'-c:v libx264',

'-c:a aac'

I wan to merge the files without re-encoding them, just merge them.

Please contact me only if you succeed to do it and have a solution.
