It is also possible to cover base layers from SVC encoded streams. That's a
detail of implementation. I foresee the following patch: (i) if downstream caps
only report Annex.A profiles then set "base_only" variable to TRUE; (ii) if
base_only is set to TRUE, discard any NAL unit that does not pertain to the
Annex.A set of nal_unit_type.

Filtering out SEI messages is optional, but desired too. This will be tracked
in another bug because this is non-essential to the decoding process, and if we
keep those, the decoding process won't be perturbed.
