Advanced live streaming
summary
Platform architecture uses RTMP ingest from broadcasters and converts incoming chunks server‑side into HLS delivery playlists with on‑the‑fly transcoding to multiple bitrates; dynamic resolution switching breaks recording so adaptive bitrate (changing video bitrate, not audio) is used instead. Mobile playback relies on libVLC and AVPlayer tuning (reduced cache, limited format probe) to cut startup to ~1.5–2s and avoid frame drops. Production metrics: ~7M events/day, ~50M views/day, peaks near 980,000 concurrent viewers.
