What is multicast RTP?
RTP allows data transfer to multiple destinations through IP multicast. RTP was developed by the Audio/Video Transport working group of the IETF standards organization. RTP is used in conjunction with other protocols such as H. 323 and RTSP.
What is SDP in streaming?
The Session Description Protocol (SDP) is a format for describing multimedia communication sessions for the purposes of announcement and invitation. Its predominant use is in support of streaming media applications, such as voice over IP (VoIP) and video conferencing.
What is in SDP?
SDP (Session Description Protocol) is the standard describing a peer-to-peer connection. SDP contains the codec, source address, and timing information of audio and video. SDP is never used alone, but by protocols like RTP and RTSP. SDP is also as component of WebRTC, which uses SDP as a way of describing a session.
What is AVP in SDP?
So in your example the sender of the SDP message wants to receive packets on port 47038. Additionally we RTP to transmit information. AVP stands for audio video profile (see Wikipedia).
What is RTMP and RTSP?
RTMP and RTSP are both protocols for livestreaming. A protocol sets out the rules for data transmission from one communication medium to another. Real-Time Messaging Protocol (RTMP) and Real-Time Streaming Protocol (RTSP) are the two protocols that support streaming with low latency.
What is simulcast in RTP?
In some application scenarios it may be desirable to send multiple differently encoded versions of the same media source in different RTP streams. This is called simulcast. This document describes how to accomplish simulcast in RTP and how to signal it in SDP.
How to get the multicast stream on a specific IP?
If you want to get the multicast stream on a specific IP and port (e.g. IP 226.1.2.3, port 1234) you can use following syntax: rtsp://192.168.0.1/&multicast_video=1&mc_group_video=226.1.2.3&mc_port_video=1234. You can also use the RTSP SETUP command to enable multicast streaming.
What is the SDP extension?
The SDP extension consists of a new media level SDP attribute that expresses capability to send and/or receive simulcast RTP streams. This Internet-Draft is submitted in full conformance with the provisions of BCP 78 and BCP 79.
What are the fields in the multicast settings?
Below is a screenshot of the multicast screen: Below is an explanation of the fields in the Multicast settings screen: Enable: This checkbox allows the user to enable Multicast functionality. Multicast Address: This field allows the user to enter a multicast address. Port: This field allows the user to enter a multicast port.
