 Reprint Please specify source: http://www.cnblogs.com/fangkm/p/4401075.html The first two blog posts complete the WEBRTC audio and video collection module, and the next step is to introduce the key audio and video coding modules. However, before introducing the audio and video coding module, we need to introduce the channel concept, and the transmission flow of each WEBRTC data is encapsulated into a c

Webrtc packages criticalsection, which can be used in windows and posix platforms. The basic structure is as follows: In the factory method, you are responsible for the creation of specific class objects, which can be called a simple factory model. A factory is responsible for the creation of all products, different products are created by inputting necessary parameters to the factory. Generally, the created products are related and inherited from an

Previous notes, finishingWEBRTC uses UDP transport by default, but it can also be transmitted over TCP.With TCP transport, servers such as Turnserver,licode,janus and servers are required.1. If you use Turnserver, you only need the client to keep the relaytcp type of candidate, the others are discarded.2. If you are using a server such as Licode,janus, TCP is not supported by default.Because they are used at the bottom of the Libnice open-source Ice library, Libnice supports TCP in newer version

This article is mainly about how the RTP packets received from the network in the MCU are put into packet buffer and taken out from packet buffer, as well as the calculation of the network delay value (optbuflevel) and the jitter buffer delay value (bufflevelfilt). Let's see how RTP voice

Summary of PHP compression and archive extensions To open the PHP user manual, we can see the following library of functions for processing compressed files, Bzip2,lzf,phar,rar,zip,zlib So what are the actual application scenarios for each of these, and we'll pick one up next. BZIP2: The official introduction is this: The BZIP2 function is used to transparently read and write bzip2 (. bz2) Compressed files. Self-Understanding as follows: This library is a file that is processed with a. bz2

In Swift, there is a structure extension, similar to the category category in OC, which is ideal for managing codeAt the same time, common access modifiers have public, internal, private, and for these three access modifiers, the impact on extension is differentIn this article, I will describe a total of four scenarios for extension under the same file and differ

Today Bo Master has an app extension needs, encountered some difficulties, here and we share, hope to progress together.General overviewExtensions (Extension) are a very large feature point for IOS 8 and OSX 10.10, and developers can provide some additional functionality to system-specific services by providing our extended access points (Extension point). For IO

In the Microsoft Standard LINQ, there is no distinctby extension and foreach extension, but in peacetime use of these two features are often used in the work, in the sense that Microsoft should include these two extensions in LINQ, but in fact why not?
