WebRTC for iOS

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. Compile the testProgramIn the process, we plan to use the libjingle Libr

How to modify the WEBRTC project (vs 2017)

I have only recently started to study webrtc deeply. If I have any questions, please leave a message.How to generate WEBRTC vs engineering under Windows see my last article.But when I modify the project, such as adding cc and H files, adding a third-party dependency library, you will find that the VS modification is useless. VS can only be used when a code reader and editor are available.This time we need t

WEBRTC Audio and Video synchronization method _ audio and video coding and decoding

Turn from: http://blog.csdn.net/lixiaowei16/article/details/53407010 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

New changes in bandwidth assessment of WEBRTC

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

WEBRTC Introductory article

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

Compile and install WebRTC in Ubuntu Svn checkout http://webrtc.googlecode.com/svn/trunk/ After the download is complete, WebRTC will get a folder named trunk by default, which contains the WebRTC source code, which i

Google Announces WebRTC Technology Roadmap

Google's first integration of WebRTC in the Chrome Dev release released this January was a source of widespread concern. Today, Google published a roadmap for the development of WebRTC technology in its blog.WebRTC is a technology for real-time video and audio communication inside the browser, and Google acquired a technology in 2010 to acquire Global IP Solutions. The technology is based on the WHATWG prot

Session Border Controler (SBC) based on WEBRTC technology

WEBRTC native app optimized for low bandwidth

This article original from Http://blog.csdn.net/voipmaker reprint annotated source.When using WEBRTC Base library to develop Android,ios native application, because the mobile terminal is not like PC side, in bandwidth stability, system performance is very big difference, so for mobile device WEBRTC need to do some optimization to improve the call effect,For example, WE

The simplest example of WEBRTC

The online example of WEBRTC is mostly code, the following is an example of a WEBRTC-to-one sample of code simplification, which is tested under Chrome 37. Where iceserver can be omitted, there is no iceserver when the same LAN can still communicate.Client code:When WEBRTC is implemented, the signaling server is required to facilitate communication between client

Sketchy WEBRTC ns (Noise suppression) module

Noise suppression, is what everyone said noise reduction. This noise reduction is a distinction between vocals and non-human voices, which is a noise.A piece of audio that contains vocals and noise is processed by the module, and in theory, only the vocal is left.WEBRTC NS In the industry is still famous, through the actual comparison test, we found that webrtc noise reduction is indeed performance and stabilityare higher than similar open source algo

Sketchy WEBRTC audio processing algorithm written in front of the words

Recently work used to WEBRTC, found that WEBRTC is a treasure trove, there are many things worth studying.Search this area a lot of information, found that the introduction of the use of WEBRTC, but for some of the algorithm researchNot much. In particular, the algorithm can be said to be concise and clear is even rarer.In fact, I would like to carefully study ea

Safari is about to support WEBRTC

Since the beginning of WEBRTC development, often asked by others, Safari browser can support WEBRTC? I also want Safari to support WEBRTC so you don't have to write native WebRTC apps or Safari plugins.Happily, Apple recently announced that WEBRTC will enter Safari and iO

WEBRTC's Voice Activity Detection (VAD) algorithm

Reproduced in the original: http://blog.csdn.net/shichaog/article/details/52399354 thank you very much. Vad (voice Activity Detection) algorithm is to detect the voice , in the far-field speech interaction scenario, VAD faces two challenges: 1. How to successfully detect the lowest energy voice (sensitivity).2. How to successfully detect in the multi-noise environment (detection rate and false detection rate).The missed response is originally the voice but not detected, and the virtual detection

WEBRTC and MSE (media source extensions) some ideas and attempts to achieve Peer-to-peer video (1) __web

Recently flv.js things seem to have ignition, and again to the MSE this thing to bring up.MSE (Media source extensions) is a new function of HTML5, and the general function is to realize streaming media function.If the MSE with WEBRTC and JS binary processing, then you can implement the server to send video to one of the browser users, the browser users will then transfer video streaming to other users of the function. is a web-side in the Peer-to-pee

Pure script compilation WebRTC for Android

In WebRTC's example project, there is an Android project called Apprtcdemo, which enables video calling (VoIP) on a wide area network. This article is intended to demonstrate the compilation of Apprtcdemo, with Windows as an example, but also for Mac and Linux. Switch to a Linux environment please specify what platform you are currently using, and if it is Linux, you can ignore this step; otherwise, you will need a virtual machine. I'm using damn windows, and I recommend vagrant, a lightweight v
