IMHO, both methods should be supported by the plugin
infrastructure, as it is
in the MediaStream class.
And the latter method is actually preferred (if the plugin
was implemented to
support it) because it gives valuable information, e.g. for
packet loss
detection, or the RTP payload type (useful in some cases for
decoding as well).
Granted all such info could be passed by option fields to
the codecs too.
