Answer 1

when you are working with FFMPEG its a good idea to install it on your OS in order to make sure that your commands are correct

in your case the problem is in your command string

[0:a]atrim=start=0:duration=20.900,setpts=PTS-STARTPTS[a2]; 

should be :

[0:a]atrim=start=0:duration=20.900,asetpts=PTS-STARTPTS[a2];

you have to use asetpts when you are using atrim filter
