@JD Wilder Thanks for reporting this issue. It has been shared with the SDK engineers and they will try to get a bugfix in the next release or follow up here.
@SinnStudio @Maze Theory @Survios Yes, there is now a CLI tool you can access via the dev console (Binary Build page). Here is the documentation: https://developer.viveport.com/documents/viveport-uploader-document.pdf
@eugie Debug.Log is a UnityEngine api and cannot be used in the callback.
Note: Unity is not thread-safe and cannot call any UnityEngine api from within callback thread.
@eugie You will likely need to use Unity to build a 360 video player and integrate the eye tracking SDK to access the data needed. There are guides/sample projects available to help you get started with a 360 video player with Unity.
