public static enum PeerConnection.SdpSemantics extends java.lang.Enum<PeerConnection.SdpSemantics>
PLAN_B will cause PeerConnection to create offers and answers with at most one audio and one video m= section with multiple RtpSenders and RtpReceivers specified as multiple a=ssrc lines within the section. This will also cause PeerConnection to ignore all but the first m= section of the same media type.
UNIFIED_PLAN will cause PeerConnection to create offers and answers with multiple m= sections where each m= section maps to one RtpSender and one RtpReceiver (an RtpTransceiver), either both audio or both video. This will also cause PeerConnection to ignore all but the first a=ssrc lines that form a Plan B stream.
For users who wish to send multiple audio/video streams and need to stay interoperable with legacy WebRTC implementations, specify PLAN_B.
For users who wish to send multiple audio/video streams and/or wish to use the new RtpTransceiver API, specify UNIFIED_PLAN.
