Low-latency HLS for a live worship service stream. H.265 at 3 Mbps for 720p (church WiFi bandwidth constraint), 1-second GOP for low latency, AAC for iPhone compatibility, MPEG-TS for HLS segment compatibility.

Each segment must start with an IDR frame, so the GOP size directly determines the minimum achievable latency — 1-second GOP = ~2-second glass-to-glass.
