            Bug ID: 25807
           Summary: Avoid sdpMangling by modifying codec preferences
                    through API.
           Product: WebRTC Working Group
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P2
         Component: WebRTC API
          Assignee: public-webrtc@w3.org
          Reporter: kiran.guduru@samsung.com
                CC: public-webrtc@w3.org

JSEP spec specifies that codec preferences requires SDP mangling and other
parameters can be set through constraints.

This is a proposal to extend RTCPeerConnection, by adding API to retrieve the
supported codecs from browser
getSupportedAudioCodecs()
getSupportedVideoCodecs()

and 

set the codec Preferences by passing prefereAudioCodecs/preferedVideoCodecs
sequences to RTCRTPSender/Receiver.

This proposal extendes RTCRTPSender/Receiver by

setCodecPreferences(preferedAudioCodecs/preferedVideoCodecs)

NOTE: [1] will be reformulated to set preferences through
RTCRTPSender/Receiver.
