webrtc multicast

Cross-platform WEBRTC WEBRTC is Google Open source of a plug-in real-time video communication technology, which is divided into web development and native development; currently supports Chrome,firefox,android,ios,opera,edge. is a true sense of cross-platform plug-in real-time video communication technology. Video applications are generally based on web-level development. This paper is mainly about the cod

In "Let WEBRTC support H264 codec" I provide a priority to use the H264 codec thinking. We can verify it on the browser side. There are three ways to verify: In JS print SDP view Chrome's log chrome_debug.log (see Open Chrome Log) Grab bag using webrtc-internals The first three kinds are no longer introduced, we look at the webrtc-internals. The

A recent study on how WebRTC speech runs on iOS found that the voice_engine of WebRTC has implemented iOS-related classes, but encountered a series of problems in specific applications. After several days of hard work, finally, we solved a series of problems and successfully realized recording and playing local loop in the simulator. Compile the testProgramIn the process, we plan to use the libjingle Libr

I have only recently started to study webrtc deeply. If I have any questions, please leave a message.How to generate WEBRTC vs engineering under Windows see my last article.But when I modify the project, such as adding cc and H files, adding a third-party dependency library, you will find that the VS modification is useless. VS can only be used when a code reader and editor are available.This time we need t

If the audio and video is not synchronized, it may cause delays, such as cotton, etc. very affect the user experience phenomenon. Therefore, it is very important. Generally speaking, the audio and video synchronization maint

The bandwidth assessment (BWE) is perhaps the most critical module in the WEBRTC video engine, which determines the amount of video data that can be generated when network congestion is not raised in video traffic. Early bandwidth assessment algorithms are relatively primitive, mostly based on packet loss estimation, the basic strategy is to gradually increase the amount of data sent, until the loss of packets detected. In order for the sender to lear

Recently, I was writing a Distributed Instant chat program. To enable normal communication between Intranet users, I want to use multicast to broadcast data" According to the query data, UDP broadcast can only be effective on the Intranet (the same network segment), while Multicast can better implement mass data across network segments. Introduction There are three transmission modes: unicast,

In other words, the client sends information to the server. The client only needs to give the Server IP address and port number, and then encapsulate the information in a message to be sent and send it out. The client does not care whether the server exists or whether it can

IP multicast (also called multicast or multicast) technology allows one or more hosts (Multicast sources) to send a single packet to multiple hosts (once and simultaneously) TCP/IP network technology. Multicast, as a one-to-multiple-point communication, is one of the effecti

Disadvantages of broadcasting: routed isolation, non-cross-network segments, wasted traffic, and hardware resourcesOSPF Build neighbor: Unicast: Too troublesome broadcast: wasting resource multicast: IGPBenefits of Multicast:1, the concept of the group2, send data reasonable use of bandwidth resources, reduce the sender's CPU resource consumption3, do not know the address of the recipient4.

In a local area network, administrators often need to send a piece of information to a group of users. If the use of a one-to-one delivery method, although it is feasible, but too troublesome, there are often leakage, wrong hair. In order to solve this group communication problem more effectively, a kind of multicast technology (also commonly called multicast communication) is presented, which is based on I

ObjectiveThe purpose of this article is to save you 10 hours (or more) of your life, or to waste 10 minutes. WEBRTC's compilation has been called a nightmare as a large cross-platform base library that Google has frequently updated. If you happen to want to compile WEBRTC under Windows, you'd better evaluate your patience in advance.As of now, I have tried almost all the articles in the Chinese blog community, which can be said to have failed. I do no

Ubuntu14.04 compile WebRTC For Android code 2014-07-24, ubuntu14.04webrtc I haven't written a blog for almost a year. Recently, I developed an instant messaging project based on Google's open-source WebRTC project. During this project, I encountered some problems when downloading WebRTC code, this is a record here, and we hope to help kids who encounter similar

"WebRTC, a name derived from the abbreviation of Web real-time communication (Web real-time communication), is a technology that supports web browsers for real-time voice conversations or video conversations, and is Google's $68.2 million acquisition of global IP in 2010 Solutions company to get a technology, Google Open source of this technology! ”Just for the more than 60 million dollar technology, it is worth studying!

One disadvantage of broadcast is that it affects all computers in the subnet, even if they are not interested in this broadcast message. Multicast can solve this problem. Multicast adopts Promotion Technology(Browsing Web pages is a drawing technology, and also a pushing technology.EmailService). Multicast is also called

Introduction to the topology structure of the networkThe structure of the network consists of three layers: the core layer, the aggregation layer and the access layer.The core layer consists of 5 core nodes (each core node is configured with a routing switch CiscoCatalyst6509), which is interconnected via gigabit fiber to an incomplete mesh structure.The aggregation layer consists of 53 nodes (one

The IP address and the MAC address are divided into three types: broadcast address, multicast address, and unicast address. First, FF: FF is undoubtedly a broadcast address. Each ENI is assigned a unique Unicast address when it leaves the factory. The first 24 bits are the ID of the equipment manufacturer, which is allocated by IEEE (Association of Electrical and Electronics Engineers, the last 24 bits are the unique ID specified by the device manufac
