Detailed Description

This describes a single item in the "Transport:" line of one stream as negotiated by the SETUP RTSP command.

Multiple transports are comma- separated ("Transport: x-read-rdt/tcp;interleaved=0-1,rtp/avp/udp; client_port=1000-1001;server_port=1800-1801") and described in separate RTSPTransportFields.

struct sockaddr_storage RTSPTransportField::destination [read]

destination IP address

int RTSPTransportField::interleaved_min

interleave ids, if TCP transport; each TCP/RTSP data packet starts with a '$', stream length and stream ID.

If the stream ID is within the range of this interleaved_min-max, then the packet belongs to this stream.

network layer transport protocol; e.g.

TCP or UDP uni-/multicast
