This guide shows you how to stream from OBS to our HDMI codec using the built-in RTMP server for low-latency, high-quality local streaming — no extra server or cloud service needed.
Why Choose a Built-in RTMP Server?
Using the built-in RTMP server eliminates the need for complex network configurations or third-party platforms. Key benefits include:

- ✅ No internet connection required
- ✅ Simple OBS integration for quick setup
- ✅ Direct HDMI output from the codec
This makes it ideal for live production studios, corporate AV systems, church streaming, education, or any local video distribution.

✅ Step 2: Configure OBS Studio
Open OBS Studio.
