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

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

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

Author: Gustavo Garcia (original link) Translation: Liu Tong Bandwidth estimation is probably the most important part of the WEBRTC video engine. The task of the Bandwidth estimation (BWE) module is to determine how much video stream you can send and not network congestion to ensure that video quality is not reduced. In the previous bandwidth estimation algorithm is very basic, in general, based on the design of packet loss. Usually we start to slowl

Some personal understanding about WEBRTC Just participated in the sound network presided over the first WEBRTC conference in Beijing, coupled with reading "hundred asked Freeswtich" written by Daniel, to it has more understanding, record for later review: 1, simple understanding, WEBRTC is a way to achieve web-to-business dial audio and video telephony technolog

Here to explain the WEBRTC in the RTP parsing, here is the main explanation of h264 analysis; About class implementations and related test files that are relevant in VP8 and VP9,WEBRTC; Regarding the RTP file parsing of H264, t

The WEBRTC's audio processing module is divided into noise reduction ns (NSX), echo cancellation AEC (Echo control Acem), Audio gain AGC, and Mute detection section . In addition WEBRTC has encapsulated a set of audio processing module APM, if it is not a special need, if users want to use the echo cancellation and other more complex modules, it is best

Differences between Winwods NLB unicast and MulticastWindows NLB (network load balancing) is a load balancing technology that Microsoft has provided on Windows 2000 Server. NLB uses a distribution algorithm to distribute Server Load balancer across multiple hosts to improve IP-based key services (such as Web, virtual private network, streaming media, Terminal Services, and proxies) scalability and availability, while detecting host faults and automatically allocating traffic to other operating h

The MAC address is a 48-bit (6-byte hexadecimal number) Address used on the second layer of Ethernet to identify the device location. The MAC address is divided into two parts. The first 24 digits are the unique identifier of the organization (oui, organizationally unique identifier), and the last 24 digits are allocated by the vendor. MAC addresses can be unicast, multicast, or broadcast. The Unicast address indicates a single device or node,

Overview:Broadcast and multicast, as the name implies, are passed to all systems in the subnet or to a system belonging to a multicast group. They apply only to UDP.For IP, we know that the host number is 1 of the broadcast address, while the Class D IP (that is, from 224.0.0.0 to 239.255.255.255) is the multicast address.For Ethernet, when the lowest bit of the

Python has complete support for sockets. some of the APIS though have a different signature than the POSIX equivalents. it is therefore possible to write multicast servers and clients in Python. multicasting is the ability to send data to select set of hosts. broadcasting in a network is to send data to all the hosts, unicast is when data is transfered between two hosts (typical one-one communication ). multicasting is the ability to send data to a

To do useful work, P2P applications must be able to discover and interact with each other. This article provides an implementation of IP multicast-based discovery. Before a software entity can participate in direct peer-to-peer interaction with P2P applications, the entity must discover the appropriate Peer-to-Peer Points to interact. All feasible P2P architectures provide a solution for Problem Discovery. In this article, I will describe the implemen

PIM-DM Basics PIM-DM uses five RIMv2 messages Hello Join/Prune (Add/CUT) Graft grafting) Graft-ACK (OK) Assert (Declaration) The PIMv2 router uses the Hello message to discover the neighbor, when the PIMv2 router PIM-SM or PIM-DM) is active, will periodically send the Hello Message on each interface configured with PIM; PIMv1 vro has similar functions, but uses Query messages. A Hello (or Query) message contains a storage time holdtime, which specifies the maximum time for a neighbor to

Let's take the multicast data sent to UDP as an example. In fact, the difference between sending a UDP multicast datagram and sending a unicast UDP datagram is not big. First, in the myudp_sendmsg function, if the source address of the sending interface is not determined and the target address is a multicast address, the source address uses inet_sock-> mc_addr. T

The MAC address is divided into three categories, namely broadcast address, multicast address and unicast address. First of all, FF:FF:FF:FF:FF:FF is undoubtedly the broadcast address. Each NIC is shipped with a single unicast address, and the first 24 digits are the manufacturer's number, assigned by the IEEE (Institute of Electrical and Electronics Engineers), and the latter 24 are the only number that the device manufacturer has developed for the N
