Structure type generated from the specification.
A description of a codec.
This should be set to true in calls to CallContentMediaDescriptionInterface::Accept() and
UpdateLocalMediaDescription() if this
codec has changed in a way that needs to be signalled over the
network. If it is set to false, the CM is allowed ignore any
differences between the current parameters and the previous ones
This mechanism may be used to save bandwidth and avoid the CM
having to calculate diffs against previous versions of this
struct, which can lead to false-positives (e.g. redundant ptime
updates).
