ObjectiveBefore writing the article "separate compilation using WEBRTC audio processing module-Android", I have been trying to compile the WEBRTC audio processing engine Voe the whole to use for his project, but limited to the poor technology, time is tight, so did not succeed. The AECM, AGC, NS, and VAD modules in the engine were compiled separately to make it work. Although it can achieve a certain effect
Explanation of Intent in Android (2) Introduction to using Intent to Broadcast events and Broadcast Receiver
The first article explains how to use Intent to start new application components. However, they can also use the sendBroadcast method to anonymously broadcast messages between components.
As a system-level message transmission mechanism, Intent can send st
Simple implementation of the custom broadcast (broadcast) mechanism
First, define a receiver in the Manifset file and set the Intent-filter
For example:
The next step is to set up a custom broadcast in the activity, as follows:
Intent Intent = new Intent ();Intent.setaction ("Com.neter.broadcast.receiver.SendDownXMLBroadCast")
In the first article, we've seen how to use intent to launch new application components, but in fact they can also use the Sendbroadcast method to broadcast messages anonymously between components.As a system-level messaging mechanism, intent can send structured messages between processes. Therefore, the broadcast receiver is implemented to monitor and respond to these
Recently, due to the needs of the project, I began to touch the WEBRTC thing. Unexpectedly the threshold of this thing is still pretty high, next share I stepped on the pit, hoping for the first contact with this thing in the future to help people.WEBRTC official websiteThe first step of course is to see the official homepage (www.webrtc.org), first the content of the homepage was roughly swept over, probably a little bit of understanding of this thin

Whether you're making video chats by visiting URLs or sharing files on your social network, WEBRTC is rapidly expanding the application horizon and looking for what can be achieved in Web applications.WEBRTC is a recommended
Recently, our team is developing a app to help people solve problem face to face.We Choose WEBRTC Protocol as our bridge among different platform (Android, IOS, browser etc).But there are a hole in Android 6.0 system, the protocol can not support Android 6.0 system.As we known, Libjingle (Http://mvnrepository.com/artifact/io.pristine) was built in December, 2015,It hasn ' t been updated in least one year. I do not know if

Due to the large space, video capture and audio capture are divided into two blog posts, where the video capture process is analyzed first. Analysis of the time of the first analysis of the

Broadcastreceiver can not only receive system broadcasts, but also receive customized broadcasts1. Define a broadcast receiver
Copy Code code as follows:
public class Myreceiver extends Broadcastreceiver
{
Public Myreceiver ()
{
LOG.I (TAG, "myreceiver");
}
Getaction () of intent can be used to distinguish between different broadcasts received
@Override
public void OnReceive (context arg0, Intent arg1)
{
String action=intent.get
First, IntroductionBroadcast receiver is a broadcast receiver that receives custom and system anchors. It can also be called a listener.Broadcast intent, like intent, is the medium of communication, and unlike intent, broadcast intent is received by multiple components at the same time.Broadcast intent broadcast mechanism, br
UDP, broadcast and Multicast (7), udp Broadcast
(Reference) TCP/IP explanation, Volume 1: Protocol
UDP is a simple datagram-oriented transport layer protocol. Each output operation of a process generates a UDP datagram and assembles it into an IP datagram to be sent. UDp datagram is encapsulated into IP datagram format, for example:
UDP Header
The fields of the UDP header are as follows:
The port number i
WEBRTC 's echo cancellation (AEC, AECM) algorithm mainly includes the following important modules: Echo delay estimation, NLMS (normalized minimum mean square adaptive algorithm), NLP (nonlinear filtering), CNG (Comfort noise generation). The General classic AEC algorithm should also include double-ended detection (DT). Considering that the NLMs, NLP and CNG used by WEBRTC belong to the classical algorithm
app Google launched), we'll see what chemistry can produce.So regardless of whether duo succeeds or not, at least we see Google's focus on social and video. In other words, even if duo is unsuccessful, Google will definitely launch other relevant apps to get into this area.2, Google is not always pushing the HTML5 standard? And there is a very important element in HTML5 is WEBRTC, on such an important occasion to show duo (Duo is based on
The goal of this project is to develop an online multiplayer game with as few server resources as possible, while expecting to run the game on one user's browser while allowing another player to connect. In addition, it is hoped that the program is as simple as possible for analysis in blogs.Application of the technologyI found WebRTC when I first came into contact with the technology, and I thought the technology was right for the project.
The newer WEBRTC source code does not have the corresponding vidoeengine with the voiceengine structure, instead of the meidaengine. Mediaengine includes the Mediaengineinterface interface and the fact that the compositemediaengine,compositemediaengine itself is also a template class, and two template references are audio engines and video engines respectively. The compositemediaengine derived class Webrtcmediaengine depends on the template parameters
