I at least looked at the thread for his dashboard background image cycle and the more I read I felt it was such a different use case that it would be hard to shoe-horn in what I wanted to do. Rather than changing images periodically or based on logic in a rule, I want the images to cycle as you are looking at the dashboard.
Maybe, maybe not.... Separate to this little project, when it comes to weather services / drivers, etc, my thought process has always been that I like to have a separation between data collection and presentation, with a few exceptions. With the EcoWitt drivers I have recently taken on, they are predominantly focussed on getting data into HE, with some convenient templates for displaying this information on a dashboard. I don't mind that approach, supplying some simple built-in display feature.
But I also would like to see more general weather display options, so, ideally, no matter what weather system you are using, everyone can make use of the display options developed, Hubigraphs provided an example of this. This project is an example of that, I plan to look at ways of downloading the images from our weather bureau under a separate set of drivers, but the cycling of the images can be an independent feature, not tied to where the images are being sourced, allowing it to be used for other weather platforms or even things like security camera stills.
So in answer to your question, I probably am not looking at supporting live streams, but certainly if someone could write code to output a series of stills then this code could display them on a dashboard.
