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.

wanted to share our live production from this past weekend! we covered a city 10k marathon using 2 dji mavic 3s, 1 air 3s, and 2 iphones running larix broadcaster. all 5 feeds ingested into castzero desktop engine on a single gaming laptop and rendered into obs browser sources under 50ms delay. switching between aerial views and runner finish line shots was insanely smooth!

yup used the multi-cam obs matrix tool (castzero.in/multi-cam-obs-matrix) to map drone1, drone2, drone3, mobile1, mobile2. kept everything organized for the switching team.
