How do I convert the original ffmpeg command to fluent-ffmpeg's command?
I found the solution how do I trim audio file. So I got 2 files trimmed what I want. And then I merged again.
[ok] ffmpeg -i ./Desktop/input1.mp3 -y -t 3 ./Desktop/new1.mp3
[ok] ffmpeg -i ./Desktop/input1.mp3 -y -ss 5 -t 10 ./Desktop/new2.mp3
[ok] ffmpeg -i "concat:./Desktop/new1.mp3|./Desktop/new2.mp3" -acodec copy ./Desktop/new3.mp3
So big confused.
