Im a developer for Low-Latency HLS protocol. I found some doubts when reading contents about preload hint/blocking. Suppose that a media segment of 2 seconds long is divided into 10 partial segments, which means that each part segment is 0.2 second long. At the point the last part segment is completed, how should I provide a preload hint? Should I give a preload hint for 11-th part, although it will never generate? or first part for next media segment? How should I write a rate index file when facing this situation? https://developer.apple.com/documentation/http_live_streaming/enabling_low-latency_hls
