Yes. The one on the stream takes precedence. As per RFC4566, sec5.7:

A session description MUST contain either at least one "c=" field in
   each media description or a single "c=" field at the session level.
   It MAY contain a single session-level "c=" field and additional "c="
   field(s) per media description, in which case the per-media values
   override the session-level settings for the respective media.
