Create a new media type definition.
mediaType | name of the media type (audio, video etc) |
sdpType | name of the SDP type |
requiredSessionId | Session ID to use, asserts if already in use |
autoStart | Default value for auto-start transmit & receive |

Create a media session suitable for the media type.
connection | Connection media session is being created for |
sessionID | ID for the media session |
Reimplemented in OpalRTPAVPMediaType, OpalMSRPMediaType, and OpalSIPIMMediaType.

Create an RTP session for this media format. By default, this will create a RTP_UDP session with the correct initial format
Only valid if UsesRTP return true
Reimplemented in SimpleMediaType< Type, sdp >, and OpalIMMediaType.
