Comment (by tmm1):

 Sorry, it looks like I am mistaken and the Brazil DVB-T issue is not
 related to SSR. Appears to be a separate issue in the AAC decoder. With
 ffmpeg master and the original sample from this ticket, I see the
 following errors:

     [aac_latm @ 0x7ff246000c00] channel element 0.2 is not allocated
     Error while decoding stream #0:4: Invalid data found when processing
     [aac_latm @ 0x7ff246000c00] element type mismatch 1 != 0
     Last message repeated 1 times
     Guessed Channel Layout for Input Stream #0.4 : 5.1
     Input stream #0:4 frame changed from rate:48000 fmt:fltp ch:6 chl:5.1
 to rate:48000 fmt:fltp ch:6 chl:5.1

 There is no mention of SSR. Sorry for hijacking this ticket.
