between a browser and the WebSocket server, but through a series of signaling, creating a channel between the browser and the browser (Peer-to-peer), which 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 video.

The greatest feature of real-time streaming media applications is real-time, while latency is the biggest enemy of real-time sex. The processing speed of media data is the important reason of delay, and the network congestion is the main cause of delay from the point of transmission. Network congestion can cause packet loss, and may result in longer data transfer times and increased latency.Congestion control is one of the important methods in real-ti

On the WWDC17, Apple has brought us a big surprise-its browser kernel WebKit will formally support WEBRTC, and future Apple browsers based on the WebKit kernel, such as the MacOS high Sierra, Safari in IOS 11 Browser and Safari Technology Preview version 32, will be used to WEBRTC technology.
The news has attracted countless webrtc developers, even more so that

Recently flv.js things seem to have ignition, and again to the MSE this thing to bring up.MSE (Media source extensions) is a new function of HTML5, and the general function is to realize streaming media function.If the MSE with WEBRTC and JS binary processing, then you can implement the server to send video to one of the browser users, the browser users will then transfer video

NDK develops live streaming program for Android-side rtmp
After a toss-up, the success of the rtmp live streaming code, through the NDK cross-compiled way, ported to Android, thus realizing the Android side acquisition camera and mic seam data, then the H264 video encoding and AAC audio encoding, and sent to the RTMP server, To enable live Android camera. The program, called Ndkrtmpencoder, introdu
