New description:
I am using ffmpeg to concatenate some clips with transitions, but it's
using up to 15G memory in my machine and it gets killed by the kernel.
there are 15 clips (1080P) and total time around 2.5 minutes.
The exact command I am using is:
/data/ffmpeg-git-20210611-amd64-static/ffmpeg -i cut_result0.mp4 -i
cut_result1.mp4 -i cut_result2.mp4 -i cut_result3.mp4 -i cut_result4.mp4

-i cut_result12.mp4 -i cut_result13.mp4 -i cut_result14.mp4
