Webrtc advantages and module splitting

webrtc What is good about the network module ：
Ensure real-time data transmission <500ms
It can accurately evaluate the bandwidth in real time REMB TCC
Excellent anti congestion algorithm GCC
Ensure the fairness of network bandwidth usage TCP GCC
Anti packet loss NACK FEC
debounce , Anti disorder sequence JitterBuffer NetEq
It can transmit all kinds of data Audio and video Text binary data

webrtc Each module of ：
network quality
Excellent design architecture
Cross platform
Security
3A modular
Audio and video engine

Audio and video engine ：
Support a variety of audio and video codecs AV1/VP8/VP9 OPUS/ISAC
It adopts the most advanced audio and video codec AV1 OPUS
Multiple audio and video formats can be interconnected VP8/H264
Can quickly integrate new codecs

3A modular
Support echo cancellation , Noise reduction and auto gain
The traditional algorithm is used to the extreme
It supports not only software methods but also hardware methods

encryption ：
Encryption twice , Such as video frames , First encrypt the video frame , When sending video frames, they are usually divided into several udp Packets are sent , At this point, encrypt these packets , Such two encryptions .

The traditional live broadcast is Adobe company rtmp/hls/tcp+ffmpeg CDN srs/nginx+rtmp/sls
Interactive live broadcast weBex company RTP/RTCP/udp+webrtc sfu
TCP It has a bandwidth evaluation method , But its implementation is not very good ,udp No, .
TCP With packet loss retransmission mechanism ,udp No, .

About the quality evaluation of audio and video communication ： Audio generally uses broadband evaluation method
