Agreed, how do I make it support both codecs? How would a user or an
application choose which decoder the data should be sent to?
This also means that the LATM support needs to be built into the ffmpeg
AAC decoder. This shouldn't be that hard though, but I have no way of
testing this as the only source of LATM/AAC I have is digital terrestrial in
NZ which uses HE-AAC.
