Description
See GstRtpRtxReceive for examples
The purpose of the sender RTX object is to keep a history of RTP packets up to a configurable limit (max-size-time or max-size-packets). It will listen for upstream custom retransmission events (GstRTPRetransmissionRequest) that comes from downstream (GstRtpSession). When receiving a request it will look up the requested seqnum in its list of stored packets. If the packet is available, it will create a RTX packet according to RFC 4588 and send this as an auxiliary stream. RTX is SSRC-multiplexed
