RTCRtpEncodingParameters Dictionary

partial dictionary RTCRtpEncodingParameters {
             RTCSsrcRange ssrcRange;
};

Member	Type	Description
ssrcRange	RTCSsrcRange	Associate a range of SSRC values with an RTCRtpReceiver or RTCRtpSender. When present in RTCRtpEncodingParameters passed in a call to RTCRtpReceiver.receive, this extension tells an RTCRtpReceiver object to demultiplex RTP packets sent by an H.264UC encoder with MRST transport, utilizing a range of SSRCs. When present in RTCRtpEncodingParameters passed in a call to to RTCRtpSender.send, this extension instructs an RTCRtpSender object utilizing an H.264UC encoder to send RTP packets with MRST transport, utilizing a range of SSRCs. [MS-SDPEXT] Section 3.1.5.31 describes extensions for synchronization source range allocation.

 

RTCSsrcRange Dictionary

dictionary RTCSsrcRange {
             unsigned long min;
             unsigned long max;
};

Member	Type	Description
max	unsigned long	End of the SSRC range.
min	unsigned long	Beginning of the SSRC range.
