interface is not the same as websocket, the communication between a browser and the WebSocket server, but through a series of signaling, to establish a browser and browser (Peer-to-peer) channel, the channel can send any data, Without having to go through the server. and WEBRTC through the implementation of MediaStream, through the browser to invoke the device's camera, microphone, so that the browser can transfer audio and videoWEBRTC is already in

Switch from using WEBRTC to build front-end video chat room--Data channel ChapterIn two browsers, it is very complex to send messages for chat, games, or file transfers. Usually, we need to set up a server to forward the data, of course, the larger the size of the case, will be expanded into multiple data centers. In t

the way you build appsNow we can use high-performance, low-latency rtcdatachannel to create better applications. Some frameworks, such as the Peerjs and PubNub WebRTC SDK, make rtcdatachannel easier to use, and its APIs are supported by various platformsThe advantages of Rtcdatachannel can change the idea of transferring data in your browser.More information Getting started with WebRTC

Recently doing a mobile end with mobile, web-side text, video, voice chat features. Text chat using WebSocket, a lot of information on the Internet, there is no difficulty. But in the video, voice chat encountered a small difficulty. have been looking for some of the SDK to

This article mainly introduces WEBRTC (we translate and collation, translator: Weizhenwei, check: Blacker), the earliest published in the "Weaving wind net"Support original, reprint must indicate the source, welcome attention to my public number blacker (Id:blackerteam or WEBRTCORGCN).Technically speaking, using a webcam for online broadcasting does not require WEBRTC. The camera itself is a server that can

extension protocols, including the RTP protocol-based scaling, and the RTCP protocol based on the message type extension, and so on. [2] The details can be found in the reference literature.three WEBRTC thread relationships and data flowWEBRTC provides two threads: signal and worker, the former responsible for signaling data processing and transmission, the latter responsible for the processing and transmission of media data. Within

WEBRTC source code, the transmission and reception of video packets is taken as an example, and the implementation of Anck packet retransmission mechanism is deeply analyzed. The main contents include: SDP negotiation Nack, receiving end packet loss determination, NACK message construction, sending, receiving and parsing, RTP packet retransmission. The following

And we use Setpreviewcallbackwithbuffer and allocate this memory in Opencamera, each time the memory is compressed, and then re-addcallbackbuffer into the system, it will not be allocated a lot of memory, The GC also does not start.

Next Tuesday launch of "Audio and video technology WEBRTC" Open class, Welcome to join!Open Course Links: http://edu.csdn.net/huiyiCourse/detail/90The course's explanatory material and code will be uploaded at the end of the Open class http://download.csdn.net/user/yangzhenpingThe following is the course information:Course Brief IntroductionThe core of WEBRTC

We have introduced WebRTC and read the example of https://apprtc.appspot.com/on the Internet (which may need to be accessed through a wall). This example is an application deployed on the Google App Engine and relies on the Gae environment, the background language is Python and also relies on the Google App Engine channel API. Therefore, it cannot be run locally
