Is it possible to achieve sub-second end-to-end latency when displaying live streaming video using APMP (Apple Projected Media Profile) with Wide FoV?
APMP supports HLS playback, but my understanding is that standard HLS introduces several seconds of latency. I would like to know whether APMP (especially Wide FoV) supports Low-Latency HLS, or if there are inherent limitations that make sub-second latency impractical.
If APMP is not suitable for this use case, are there any recommended alternatives within AVFoundation or related frameworks for rendering wide-FoV live video with very low latency?
Thank you for any insights.
