How to embed latest youtube video?

So it is easy to embed a particular youtube video.

How can you make the embed code display the most recent video automatically?

I’m puzzled…

Thanks anyone

The code to display a YouTube video has a link to a specific video. I don’t know if you can predict the video numbers of your won videos, but even if you could, presumably you’d have to write some kind of script to find the latest video, but it doesn’t sound easy (if possible) to do.
