Comment (by feelart):

 I do wish not to use the bitstream filter, I'd rather prefer it is left
 internally.
 However, as I understood it is a must requirement for m4a, flv, mp4 and
 mov.

 As I understand, bsf is a mutual exclusive flag: you must use it on
 certain containers (m4a, flv, mp4 and mov), but must not on all others.

 In the following CLI, ffmpeg clearly mentions "Conversion failed!" and no
 empty output (1 Kb)is created.

 While in 1st example, namely:
 {{{
 >ffmpeg -i aac_test.aac -c:a copy -bsf:a aac_adtstoasc
 aac_try_with_bsf.aac
 }}}
 ffmpeg ought to exist, but currently does not and more prone to error
 creates an apparently good output.

 This is either a feature enhancement or bug.
