There are two types of echoes in voice calls:1. Circuit echo (already resolved)2. Acoustic echoTwo echo cancellation modules are designed in the WEBRTC source code:1.AEC (Acoustic Echo canceller): PC side2.AECM (Acoustic Echo Canceller mobile): MobileAECM:Causes of acoustic Echo:The voice of the proximal speaker is picked up by his microphone and transmitted to the far end via the network,The sound from the remote speaker is picked up by the microphon

 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

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

In the previous article (WEBRTC Audio-related Neteq (ii): Data structure) Neteq the main data structures, to understand the mechanism of Neteq lay a good foundation. 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

Today, I want to capture some excellent code, but the dependency between files is too large and difficult to find. It seems that I found a place. Lock usage: 1. multi-threaded access to the same variable requires locking. 2. A lock is a kind of resource. It is necessary to apply locking and lock-in, and create and release corresponding resources. The following is the lock code: # Ifndef TALK_BASE_CRITICALSECTION_H __# Define TALK_BASE_CRITICALSECTION_H __ # Include "talk/base/constructormagic.

error Because the Redis service is self-booting, it will not start again, so loading the configuration file is a failure. There is also no Redis boot small box (below the picture, slowly looking down), note that the Windows version of the Redis installation, the default boot loaded configuration file is redis.windows-service.conf, as shown in:2. Invalid passwordAlthough the password is set in the configuration file (redis.windows.conf), the password

PHP 5.4 has a built-in Web server that is handy for native development because you no longer have to install Web server software like Apache, you can launch PHP's Web server directly from the command line. The startup method is simple, enter the directory where the project is located at the command line, and then use the-s parameter to start the service, you need to specify the host address and port, and all the request information will be displayed in the console window as shown in: Shortcut T
