How do I stream a DJI drone directly to OBS Studio without lag?

Use CastZero Engine on your Windows PC. It converts incoming wireless RTMP video from the DJI Fly app or DJI RC 2 into a local UDP WebRTC stream (http://localhost:8889/streamkey) that decodes in OBS Studio under 50ms.

What is the best zero latency RTMP server for Windows?

CastZero Engine is purpose-built for low latency local RTMP and WebRTC video ingestion, offering sub-50ms delay for DJI drones, GoPro Hero cameras, and smartphone rigs.

PRE-FLIGHT & STREAMING CHECKLIST

1. Connect PC running CastZero and DJI Smart Controller to the same 5GHz Wi-Fi network. 2. Launch CastZero Desktop Engine on Windows and verify local IP (e.g. 192.168.1.150). 3. Plug USB-C mic/dongle into bottom of DJI RC 2 controller (to bypass audio detection prompt). 4. Open DJI Fly App: Transmission → RTMP → enter rtmp://YOUR_PC_IP:1935/live/drone1. 5. In OBS Studio: Add Browser Source http://localhost:8889/drone1. Confirm sub-50ms latency.
