Designing a video streaming server involves multiple technical aspects and intricate architectural decisions. Here's a high-level consideration and recommended steps from a system design perspective: 1. **Define Requirements (確定需求)**: - **Throughput (吞吐量)**: How many client connections does your server need to support simultaneously? - **Latency (延遲)**: How quickly should the streaming begin to play? - **Video Quality (視頻質量)**: Are you supporting resolutions like 4K, 1080p, 720p, etc.? - **Streaming Type (串流類型)**: Do you need to support live streaming or VOD (Video on Demand)? 2. **Choose Appropriate Protocols (選擇適當的協議)**: - **HLS (HTTP Live Streaming)** and **DASH (Dynamic Adaptive Streaming over HTTP)** are popular streaming protocols today. Both support Adaptive Bitrate Streaming (ABR), adjusting video quality dynamically based on a user's network condition. - **RTMP (Real-Time Messaging Protocol)**: Though less commonly used now, it remains important in ce
