This guide walks through setting up ZLMediaKit in Docker, installing FFmpeg, adding a Spring Boot backend with configuration and service classes to launch and manage RTMP streams, and provides front‑end HTML/JavaScript for playing the live FLV or HLS streams.
This article details the end‑to‑end low‑latency video streaming architecture, measurement methods, and optimization techniques—including FLV‑2s, RTM, MiniSDP, buffer‑driven speed‑up, and CDN strategies—that Douyin's Volcano Engine video cloud employed to achieve sub‑2‑second latency and high QoE for World Cup live broadcasts.
This article explains the end‑to‑end workflow of Douyu’s fast live streaming system, detailing how FLV tags are converted to RTP packets and back, covering WebRTC’s SDP/ICE/DTLS handshake, FLV and RTP header structures, payload formats for audio (OPUS) and video (H.264), and the server‑side processing pipeline.
To accurately benchmark and reduce end-to-end latency on large live-streaming platforms, this article details practical measurement frameworks for both HTTP-FLV—using custom SEI timestamps and cloud-synced clocks—and WebRTC—leveraging RTCPeerConnection stats to dissect uplink, server, jitter, decoding, and render delays.
HJPlayer is a lightweight JavaScript library that enables browsers to play H264/AAC encoded FLV live and VOD streams as well as HLS streams by demuxing them into fragmented MP4 and feeding them through the Media Source Extensions API, offering both ES6 module and script tag integration.
This article details how to replace WebRTC‑based multi‑audio streaming with HTTP‑FLV or HLS on the web, covering iOS Safari limitations, demuxing FLV, building ADTS headers, decoding with the Web Audio API, channel merging, and real‑time audio visualization using AnalyserNode.
This article explains why live streaming platforms rely on Content Delivery Networks, describes the CDN architecture and workflow, and compares the main streaming protocols—RTMP, HLS, and FLV—highlighting their characteristics and impact on latency and stability.
