Abstract: E-commerce live streaming has evolved from a "nice-to-have" to a "must-have survival tool," yet many businesses face core challenges when building live streaming systems: complex technical architecture, unstable high-concurrency performance, and runaway bandwidth costs. This article traces the real growth journey of an e-commerce live streaming project from zero to multi-million GMV, fully dissecting the technical choices and best practices across six stages: push streaming, intelligent transcoding, CDN distribution, terminal playback, real-time interaction, and data review — with ready-to-use resource configuration plans and cost calculation formulas.

E-commerce live streaming seems simple — turn on a camera, connect to a platform, and you're live. But as business scales from hundreds to tens of thousands or hundreds of thousands of viewers, problems explode:
Technical architecture determines business ceiling. This article helps you solve it all at once.
| Approach | Use Case | Recommended Config |
|---|---|---|
| Tencent RT-Cube Live SDK | In-app live streaming | iOS/Android/Flutter full-platform |
| OBS + RTMP Push | PC professional streaming | With capture card and pro mic |
| SRT Protocol Push | Weak network (outdoor/warehouse) | Better packet-loss resistance than RTMP |
| WebRTC Push | Browser-based no-plugin streaming | 1,000 concurrent per domain |
Best Practice: Use RTMP protocol for e-commerce streaming (best stability), set bitrate to 2-3Mbps (720P), not exceeding 4Mbps.
| Transcoding Plan | Bitrate Compression | Quality | Use Case | Monthly Cost (100h/day) |
|---|---|---|---|---|
| No transcoding (passthrough) | 0% | Depends on source | No quality requirements | Traffic fees only |
| Standard H.264 | ~20% | Standard | Regular daily streaming | ¥90/100h |
| Top Speed Codec | 50%+ | Same quality | Flash sales, branded streams | ¥299/100h |
Core recommendation: Strongly recommend enabling Top Speed Codec for e-commerce. Although transcoding has costs, the 50%+ bandwidth savings far exceed transcoding expenses.
