How can the receiver know which media type and codec are in use?

This is:

- Alice signals its media info to Bob, and includes info for Bob to
set in the RTP header extension (in case Bob wants to send media to
Alice even before Alice receives the media info signaling from Bob).

- Alice starts receiving RTP packets (the N first ones include such a
negotiated RTP header extension).

- How can Alice know which codec do those RTP packet include?

Do I miss something?
