For this workflow you will require:

• MacOS system (with connection to Ethernet + WiFi)
• Insta360 One R camera,
• Insta360 mobile app installed on your smartphone
• ZM-1 microphone
• OBS (https://obsproject.com/)
• ZYLIA Streaming application (https://www.zylia.co/zylia-streaming-application-download.html)
• MacOS RTMP Local host application (https://github.com/sallar/mac-local-rtmp-server)
• Facebook profile

This project consists of 3 main parts:
A. Receiving a live 360° video from the Insta360 to OBS
B. Receiving Ambisonics audio from the ZM-1microphone to OBS.
C. Configuring Facebook for live stream of 360° video with Ambisonics audio

​A. Receiving a live 360° video from the Insta360 to OBS
1. Turn On the Insta360 camera and connect your computer Wi-Fi to the corresponding Insta360 Wi-Fi network.

2. Simultaneously, connect your computer to your local ethernet using an ethernet cable. On your network preferences you should be connected with Ethernet and Wi-Fi.
On step number 4 you will need the IP address for the Insta360 Wi-Fi referred on your network preferences.

3. On your MacOS, open the application Local RTMP server (https://github.com/sallar/mac-local-rtmp-server).
This simple application will be used to receive a live stream from the Insta360 camera. It also provides you the local host address for OBS.

4. Using your smartphone, connect to the Insta360 camera Wi-Fi and Bluetooth using the Insta360 mobile application.

​Scroll to the option “Live” and select RTMP server.
Here you should add the address to the Insta360 Wi-Fi mentioned on step 2.
In the end of the address add a unique key (it can be anything).

rtmp://Insta360IPaddress.live/abc
rtmp://192.168.42.3/live/abc (example)

Start streaming from the Insta360. The Local RTMP server application icon should now turn red as an indication of receiving the stream.

5. Open OBS and setup your project:

• On the video resolution you require a 2:1 format such as 1280x640
• Also, select your audio to 4.0 to receive 1st order Ambisonics audio later.

6. To receive the video stream from the Insta360 to OBS:

• On the Sources, click the plus sign and add “Media Source”
• Disable “Local File”
• On the input add the same address as the Insta360 camera, you may also use:
  • rtmp://localhost/live/abc

After adding the source, you should be receiving a 360° video from the Insta360 into OBS.
