Hello Wowza Community!
I hope you find value in today’s post:
Our updated RTSP explainer covers how the protocol works and how Wowza Streaming Engine ingests camera feeds for HLS, LL-HLS, MPEG-DASH, and WebRTC delivery. The guide covers:
- How RTSP, RTP, and RTCP work together
- When RTP runs over UDP or interleaved TCP
- Default ports, URL format, and RTSPS and SRTP encryption
- New settings in Wowza Streaming Engine 4.12 for cameras behind NAT
- Separate UDP port ranges for RTSP ingest and WebRTC on the same server
- Persistent camera connections, ONVIF discovery, and stream testing with VLC
- Repackaging RTSP as WebRTC for sub-second browser playback
IP cameras still rely on RTSP, but browsers can’t play it, and NAT, firewalls, and port conflicts often get in the way of a working stream. Read our guide if you’ve been having issues with RTSP streaming: What Is RTSP? Protocol, Streams, Ports, and URLs | Wowza
