WebRTC represents the best technology in the field of real-time communication since the date of birth. But for a long time, it supported the video encoder only VP8, and later with H265/VP9 as the representative of the birth of the next generation of video Encoders, WebRTC appeared VP9 Codec. The most widely used H264 has been kept out of sight. Until Cisco announces its H264 codec open source for OpenH264,
What is WEBRTC.
As we all know, the browser itself does not support each other directly to establish channels for communication, are through the server relay. For example, now there are two clients, A and B, they want to communicate, first need a and server, B and server to establish a channel between. A to send a message to B, a first message sent to the server, the server to a message relay, sent to B, and vice versa. In this way a message between A

Every time I try to look at the implementation of the specific logic in chromium kernel, it's time to look at the code and find the logic. Of course, a lot of information on the Internet can be seen, but every time I read this information, I would like to ask: really so? Does the new version of kernel change this logic?So, in order to let themselves be confused, or to see the source code, a little bit to see the call stack. Then we can understand the

If you use the above method to successfully use chromium OS, Don't be proud of it too early. Since it is free, there must be a reduction. The difference between the two is explained by Google:

There were a few simple commands at the time, and at last there was no fac
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.

Audio and video synchronization is related to the most intuitive user experience of multimedia products, audio and video media data transmission and rendering playback of the most basic quality assurance. 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

Google Chrome/chromium has been using WebKit (WebCore) as the HTML/CSS rendering engine since its launch. WebKit was previously developed by Apple by the khtml project fork for the web engine of the Safari browser. Due to loose protocols, lightweight design, and convenient embedded APIs in applications, WebKit has become popular. Besides Google Chrome/chrom
