[Project 1 live broadcast]☞2. Pull live streams and broadcast ProjectsI. Introduction to video technology 1. Video is structured data. Data is transmitted during live broadcasting, which is a small unit of video. Video = image + audio The original image data in the video is usually compressed in H.264 encoding format. Audio sample data is usually compressed in AAC encoding format. 2. Real-Time Video Tran

It is not recommended to compile individual modules in the WEBRTC separately for use. Yesterday, I was fortunate enough to ask the Google forum about the delay in computing the AECM module, and Project member said churn this delay actually didn't help the AECM effect, which only sped up the convergence of the built-in latency estimator when the AECM started, and if the delay in the update was incorrect, it would even make AE The CM built-in delay

What role does it play in the lan?The last value of 255 is the reserved broadcast address in the network. broadcast means to send data packets to * without knowing the IP address of the other party *. *. *. 255 IP address. packets sent here are automatically forwarded to hosts 1-, which occupy network resources and is called "broadcast storm ". However, there a

Transferred from: http://www.xuebuyuan.com/1248366.htmlThe bandwidth adaptive algorithm in WEBRTC is divided into two types:1, the originator bandwidth control, the principle is the RTCP in the packet loss statistics to dynamically increase or decrease the bandwidth, in the reduction of bandwidth using the TFRC algorithm to increase the smoothness.2, the receiver bandwidth estimation, the principle is and by the receipt of RTP data, the estimated band

based on WebRTC of the MCU Open Source Projects Licode the environment to buildDue to the needs of the project, we need to build multi-person communication and investigate three common structures of multi-person communication:1. The previous blog has been based on Codelab for three people chatting, a multi-person system based on Mesh structure. Specifically, the fake has n+1 client, then for each client needs to establish peerconnection with other N o

Recently in the docking WebRTC to Android phone, there is a demand is the mobile phone horizontal screen when the other side of the image rotation, study the code of WEBRTC Video_render found that the remote video rendering using OPENGLES20 or Surfaceview implementation, Where OPENGLES20 uses hardware rendering, so performance is better, so simply add the VideoRenderOpenGles20 class in the video_render_open

1. Introduction It is well known that the browser itself does not support the direct establishment of communication channels between each other through the server to relay. For example, there are now 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 send the message to the server, the server to a message to relay, sent to B, the reverse is the same. So a message between A and b through

WEBRTC FEC (forward error-correcting code) is an important part of its QoS, which can be used to recover original data packets when packet loss is lost, reduce retransmission times, reduce latency and improve video quality. It is an implementation of the RFC 5109 standard. Below, we will delve into its rationale. Redundant coding To understand the FEC in WEBRTC, you need to first understand red Packet. The

Quality Scaler is WEBRTC in accordance with the video quality, adaptive adjustment resolution of the scheme, the idea is generally: to observe the video encoding loss frame rate and QP changes, determine whether the capturer in the adaptor to adjust the encoding resolution. Its code is located at:$ (ROOT)/src/webrtc/modules/video_coding/utilityThe implementation is fairly simple,Observe the average QP and d
