Live RTSP Test Feed

Need an active live RTSP stream to test this integration?

Generate a free 20-minute authenticated live H.264 video feed with frame counters to test in VLC, OpenCV, or NVR software.

#1Candidate Types Explained

- Host: Local LAN IP address (Fastest, direct peer-to-peer on same network) - Srflx (Server Reflexive): Public WAN IP discovered via STUN server - Relay: TURN server relay address (Guaranteed connection across symmetric NATs)
