WebRTC supports the use of its own codec (limited to native development), audio, video can be. Here the video coding as an example to analyze the corresponding source code in the WebRTC. createpeerconnectionfactory In Webrtc/api/peerconnectioninterface.h there is a method Createpeerconnectionfactory, the prototype is as follows: Inline rtc::scoped_refptr As you

Original address: Https://www.chromium.org/developers/design-documents/process-models This article describes the different process models supported by chromium, as well as the pros and cons of various models. 1. Overview Most of today's Web pages contain a lot of dynamic code, which makes them look more like applications than mere documents. This change makes the browser no longer a mere document renderer, but an "operating system".

The implementation is a Python-based Gae app that we need to download Goog

Part I introduces basic concepts such as OpenGL context and drawing surface, and why multiple 3D contexts are required for chromium. This article will continue with this topic to discuss why chromium introduces virtual 3D context and what is the difference between virtual context switching.Restrictions on multiple 3D contexts Chromium requires multiple 3D context

As a browser, it is the most important work to render the Web page quickly. In order to do this, chromium to do a lot of optimization work. These optimizations are effective and represent today's most advanced web rendering techniques. It is worth mentioning that these rendering techniques apply not only to Web page rendering, but also to native system UI rendering. For example, on an Android system, we can see similarities between the two in renderin

If you really want to learn how chromium works, this document is designed for you. You will get the chromium code and compile it. Then you will use Visual Studio 2005debugger to debug it and see how it runs. For more information, you will know how it handles user operations. Tip: This document is provided to Windows system developers and testers and shows them how to run the Code. If you have not set up th

The operating system (OS) has become an essential part of our lives. A new operating system model that uses "cloud computing" to achieve most of the functionality and where local computers store only a small amount of information is emerging, compared to traditional local operating systems such as Windows and Mac OS. Chromium OS is such a lightweight, cloud-oriented operating system. Google's new operating system is indeed called Chrome O

After Ubuntu14.04 is installed, install AdobeFlashPlayer first. Generally, if UbuntuRestrictedExtras is installed, FlashPlayer should be able to work and watch online videos, such as YouTube, on the Internet. In fact, this is not because Chromium is used on Ubuntu14.04. When you use other Web browsers such as Firefox and Chrom After Ubuntu 14.04 is installed, install Adobe Flash Player first. In general, if Ubuntu Restricted Extras is installed, Flash

Want to try the use of selenium on the arm board is not possible, found that Firefox does not work, the Internet has provided chrome installation hand Shun, but there is no arm version of the corresponding chromedriver, can only be engaged.The method described here is to compile directly on the Raspberry Pi, compile time in about 36 hours, compile 24 hours, last link time 12 hoursPre-Preparation:1. Mobile hard disk free space above 10G, swap and code, and compile directories need to be placed on

Android Chromium WebView learning startup, chromiumwebview Android provides WebView Based on Chromium from 4.4. Previously, WebView was implemented based on WebKit. WebKit provides basic functions such as webpage parsing, layout and rendering, and JS running. Chromium provides basic frameworks such as processes, threads, and rendering for WebView Based on WebKit.

This article is translated from WEBRTC data channelsIn 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 this case, there is a high latency and it is difficult to guarantee the privacy of the data.These issues can be addressed through the Rtcdatachannel API provided by

Install the Chromium browser in Ubuntu 16.04 In Ubuntu 16.04, apart from Chromium's failure to support Flash Player installation, other Firefox and Chrome browsers support Flash Player installation. Google Chrome has the distinction between Chromium and Chrome. Many people have a vague understanding of this and cannot clearly understand it. The two are actually one. In short,

Label: chromium syncpoint Abstract: The GPU process architecture in chromium allows multiple GPU clients to access the GPU service at the same time, while multiple GPU clients may have data dependencies, such as when rendering a webgl page, therefore, a synchronization mechanism is required to ensure the order of GPU operations. This article discusses the synchronization between GPU clients in a multi-proce

Said Nat before the penetration of a few about the concept of WEBRTC, may have been the same as the author of the WEBRTC concept of the wrong understanding of the classmate.

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-time streaming media application quality assura
