Nice overview. The point about RTSP being a first-mile ingest protocol rather than a playback one is the key framing, and it’s often missed. At Ant Media we see the same pattern with IP cameras and drones: RTSP in, then WebRTC out for sub-second browser playback, with HLS as a fallback for larger audiences. Latency also depends a lot on the transport (UDP vs. TCP interleaved) and on camera-side buffering, so real-world numbers vary by deployment. For anyone who wants another take on how RTSP works, we’ve covered it here: https://antmedia.io/rtsp-explained-what-is-rtsp-how-it-works/

Useful comparison. A hybrid setup, with AV1 where supported and H.264 as the fallback, is the practical route for live streaming today. At Ant Media, AV1 plays natively over WebRTC in modern browsers, and adaptive bitrate transcodes it to H.264 for HLS/DASH and for browsers without AV1 support. Our guide to the H.264, H.265, AV1, and VP9 trade-offs is here for anyone weighing codec choices: https://antmedia.io/video-codecs-streaming-guide/
