Good question.
The thing is the design is mainly done to support the broadest use
case, which is FLV. FLV contains also tags and the like, which we want
to query from the parser.
Also, separating demux from decode serves the purpose of indexing
offset to keyframes, which you can seek to.

In any case the current users expect to find timestamps in the
queue, so your best bet would be to demux-and-decode in one
step and store the result in the queues, then do nothing
from the decoder (except a memory copy).

Mind you: might take up a lot of memory if bufferTime (user-defined)
is big.
