In order to understand the RTSP protocol more clearly, this paper designs a simplest RTSP client program, which sends the options, DESCRIBE, Setup, PLAY, teardown requests to rtsp in turn to view the data returned by the server. Both RTP and RTCP communication are established, and a packet of RTP and a packet of RTCP packets are received.

in a simple sentence summary: RTSP initiate/End streaming media (application layer), RTP transport Stream Media data (transport layer), RTCP to RTP control, synchronization (transport layer).
The reason for this is a little confusing, because the CTC standard does not require RTCP, so in the standard RTSP code does not see the relevant parts. In the private

TensorFlow implements AutoEncoder self-encoder,
I. Overview
AutoEncoder is a learning method that compresses and downgrades the high-dimensional features of data, and then undergoes the opposite decoding process. The final result obtained by decoding is compared with the original data during the learning process. The loss function is reduced by modifying the weight offset parameter, which continuously improves the ability to restore the original data.

Ii. Streaming Media ProtocolReal-Time Transport Protocol (PRT) is a network protocol used to process multimedia data streams over the Internet. It can be used in one-to-one (unicast, unicast) scenarios) or you can transmit streaming media data in real time in a one-to-multiple (Multi-play) network environment. RTP usually uses UDP for multimedia data transmission, but other protocols such as TCP or ATM can be used if needed. The entire RTP protocol consists of two closely related par

The core of the trained segmentation engine consists of a coded network, and a corresponding decoding network, followed by a classification layer at a pixel level. The architecture of the Encoder network is the sam

RTSP protocol analysis1. Overview:RTSP (Real Time Streaming Protocol) is an application layer Protocol in the TCP/IP Protocol system. It is an ietf rfc standard submitted by Columbia University, Netscape and RealNetworks. This Protocol defines how one-to-multiple applications can effectively transmit multimedia data over an IP network. It is similar to the HTTP traffic control protocol. Both use plain text to send information, and the

The RTP protocol details the standard packet format for transmitting audio and video over the Internet. RTP protocols are commonly used in streaming media systems (with the RTCP protocol), vi
from the source side to the server can be reused, that is, a path-by-step.
The server side maintains a list of all the camera sources that are being distributed.
The server is not connected to the source side in the spare state, and the connection process is initiated only if it is required.
When all client ends a request to a source end. The server stops fetching data from the source side. Disconnect.
The Darwin system already has some of the conditions we need: The Rtspclient
transmit multimedia data over an IP network. RTSP provides a scalable framework that enables real-time data, such as audio and video, to be controlled and on-demand. Data sources include field data and data that is stored in a clip. The protocol is designed to control multiple data-sending connections, providing a way to select Send channels, such as UDP, multicast UDP, and TCP, and provide a way to select the RTP-based send mechanism.RTSP (Real time
