[FFmpeg-devel] [PATCH] avcodec/aac_parser: fix aac profile probing

[Nicolas Gaullier]

Reverts 64bb91fd3b5a00a8849531c7e8dd207f2a626096 except the
key_frame setting for aac.
See also 696ea1c2236842572df88d573e24a39be3f19c98.
Don't force the profile as it may override the correct value
set by the decoder (HE/HEv2).

Fixes #11600
