21 getParameters
22 When getParameters is called, the RTCRtpParameters dictionary is constructed
23 as follows:
24
Soares Chen172fe9d2017-07-18 09:30:18[diff] [blame]25 - The headerExtensions sequence is populated based on the header extensions that
26 the receiver is currently prepared to receive.
27
28 - The codecs sequence is populated based on the codecs that the receiver is currently
29 prepared to receive.
30
31 - rtcp.reducedSize is set to true if the receiver is currently prepared to receive
32 reduced-size RTCP packets, and false otherwise. rtcp.cname is left undefined.
