 Summary of the bug:
 While using "-bsf:a aac_adtstoasc" filter on ADTS files having ID3Tag, the
 following message is displayed in red:
 ''Error parsing ADTS frame header!''
 ''Error applying bitstream filters to an output packet for stream #0:0.''
 But the output file is working fine.

 How to reproduce:
 % ffmpeg -y -i Always_v4.aac -c:a copy -bsf:a aac_adtstoasc aac_bsf.m4a
