That is only part of the issue; the more immediate problem is that we an
Asterisk 'format' encompasses the codec, bitrate, and all other
parameters associated with the stream. However, for some audio codecs
(Speex and others), and all video codecs, there are many possible
combinations of these parameters.

This means that Asterisk needs to be able to identify a stream's codec
and all the other bits and negotiate those without treating them as a
separate 'format'.
