How to view the video in Dashboard

Seeed-Studio/node-red-contrib-ml: Get started with AI vision at the edge with no coding experience at all! (github.com)

i use these open source project which is developed on Node-Red and designed for Nvidia Jetson, but they have not shown how to view a video in the dashboard. How can I get this feature?

I don’t have answer for this due to they’re developed by 3rd party, you may contact with them. Thanks
