Interface Media

All Superinterfaces:

Cloneable, Field, Serializable

All Known Implementing Classes:

MediaField

public interface Media
extends Field

A Media represents an m= field contained within a MediaDescription. The Media identifies information about the format(s) of the media associated with the MediaDescription. The Media field includes: a mediaType (e.g. audio, video, etc.) a port number (or set of ports) a protocol to be used (e.g. RTP/AVP) a set of media formats which correspond to Attributes associated with the media description. Here is an example: m=audio 60000 RTP/AVP 0 a=rtpmap:0 PCMU/8000 This example identifies that the client can receive audio on port 60000 in format 0 which corresponds to PCMU/8000. Please refer to IETF RFC 2327 for a description of SDP.
