##### Version 2.9.89 This guide explains how to set up `RTMP streaming` inbound to the **ORBNET Streaming Engine**. This process allows you to ingest live video streams from external devices—such as drones, mobile phones, or any RTMP-capable source—into **Milestone XProtect** using the **ORB Driver**. >[!note] >**RTMP**, or **Real-Time Messaging Protocol**, is a protocol developed by Macromedia (now owned by Adobe) for streaming audio, video, and data over the Internet. It was originally designed for high-performance streaming of media between a server and Adobe Flash Player, but its use has expanded over time. > **Key Features of RTMP:** >- Low Latency: RTMP is designed for low-latency communication, making it suitable for live streaming applications. >- Adaptive Streaming: RTMP supports adaptive bitrate streaming, allowing the quality of the stream to adjust dynamically based on network conditions. >- Protocol Variants: There are different variants of RTMP, including RTMPT (tunneled through HTTP), RTMPS (secure version over SSL), and RTMPE (encrypted version). >- Support for Multiple Media Types: RTMP can handle audio and video codecs, including H.264 for video and AAC for audio. ## Prerequisites Before you begin, ensure you have the following: - A running instance of the **ORBNET Streaming Engine**, accessible via its `external IP address`. *Ensure that the **Streaming Engine** is properly secured and that only authorized devices can send streams to it.* - The **ORB Driver** installed in **Milestone XProtect**. See [[ORB Driver/Quick Start Guide|Quick Start Guide]] - An external device capable of `RTMP streaming` (e.g., a DJI drone with the DJI Go 4 app). - Network connectivity between the external device, the Streaming Engine, and the Milestone XProtect server. ## Setting up the RTMP Stream on the External Device To send an `RTMP stream` to the **Streaming Engine**, configure your external device with the appropriate `RTMP URL`. ![[z_img/b653c08140a82dd1e7beed1baf8054c2_MD5.jpeg|650]] ==All-In-One is the simplest method however there are many other configurations== 1. Determine the `external IP address` of your **Streaming Engine**. We'll denote this as `<streaming-engine-ip>`. 2. Configure the External Firewall and Software Firewall on the server with the **Streaming Engine** service to allow `RTMP - 1935` default. 3. Choose a unique and secure stream key. This acts as a password for your stream. Use a device reference or random string without uppercase letters or symbols to avoid compatibility issues (e.g., "hd3a25w3tzf2"). 4. Construct the `RTMP URL` in the following format: ``` rtmp://<streaming-engine-ip>/live/<stream-key> ``` For example: ``` rtmp://96.7.128.198/live/hd3a25w3tzf2 ``` 5. Configure your external device to use this `RTMP URL` for **live streaming**. **Example with DJI Go 4 App:** - Open the DJI Go 4 app. - Navigate to **General Settings**. - Select **Choose Live Streaming Platform**. - Choose **RTMP Custom**. - Enter the RTMP URL with the stream key. - Click **Next**, then **Start** to begin live streaming. ![[z_img/8ef62842a695981f97a84e4a02deed1c_MD5.jpeg]] **Note:** Ensure the external device has network access to the Streaming Engine on port 1935 (the default RTMP port). ## Connecting to the RTSP Stream with ORB Driver Once the Streaming Engine receives the RTMP stream, it restreams it as an RTSP stream. The RTSP URL follows this format: ``` rtsp://<streaming-engine-ip>:554/<stream-key> ``` For example: (*Using local LAN IP*) ``` rtsp://192.168.1.100:554/hd3a25w3tzf2 ``` To connect to this stream in Milestone XProtect using the ORB Driver: 1. Open the Milestone XProtect Management Client. 2. Add a new device using the ORB Driver. 3. Select the desired video channel. 4. Go to the **Settings** tab for that channel. 5. Enter the RTSP URL in the channel settings. ![[z_img/7703f9f582e4ca5da62a0172ca1b88cd_MD5.jpeg]] For detailed steps on adding and configuring a video source with the **ORB Driver**, refer to the [[ORB Driver/Quick Start Guide|Quick Start Guide]]. > [!warning] > Do not include the `/live` parameter in the RTSP URL. It is only required in the RTMP URL. ## Troubleshooting If you encounter issues, consider the following: - **External Device Cannot Connect to Streaming Engine:** - Ensure the Streaming Engine is running and accessible on the network. - Verify that port 1935 is open and not blocked by firewalls. - Check that the RTMP URL is correctly formatted. - **RTSP Stream Is Not Available:** - Confirm that the Streaming Engine is receiving the RTMP stream. Check logs or status indicators if available. - Ensure the stream key in the RTSP URL matches the one used in the RTMP URL. - **Issues with ORB Driver:** - Verify that the ORB Driver is properly installed and configured in Milestone XProtect. - Consult the ORB Driver documentation for additional troubleshooting steps.
