Yes you are right.  I have never spotted that.

INFO: Command: "ffmpeg" "-loglevel" "fatal" "-stats" "-y" "-i" 
"-c:v" "copy" "-c:a" "copy" "-bsf:a" "aac_adtstoasc" 

If you use –verbose you will see the command it passes to AtomicParsley 
which is something you would not want to generate manually.  The easiest

If you want to find the ffmpeg command in the code for v3.02 it is at line 
@cmd = (
        @{ $binopts->{ffmpeg} },

7025 push @input_opts, ( '-i', $video_file ) if $video_ok;

7028 push @codec_opts, ( '-c:v', 'copy', '-c:a', 'copy' );

7039 push @filter_opts, ( '-bsf:a', 'aac_adtstoasc' );
