Comment (by mkoch):

 Here is a simpler example for reproducing the problem, only two steps are
 required:

 ffmpeg -f lavfi -i testsrc2=size=vga -f lavfi -i sine=1000 -t 6 -y
 video.mp4

 ffmpeg -i video.mp4 -i video.mp4 -filter_complex
 "[0:a][1:a]amix=weights='1.0 0.1'" -y out.mp4

 You can hear that the audio from the first input ends too early at 4s. But
 both input files are the same and have 6s audio.
