Membrane.RTP.RTXParser (Membrane RTP plugin v0.31.0)

An element responsible for handling retransmission packets (rtx) defined in RFC 4588.

It parses RTX packet and recreates the lost packet by stripping rtx header from buffer's payload and updating rtp metadata. The changed fields are:

sequence_number - set to value transported in rtx header
payload_type - set via original_payload_type option
if rid_id and repaired_rid_id are provided, the former replaces the latter in a matching :extensions entry
