Why doesn't the video tag in Google Chrome?

Good afternoon. Why can not I use the video tag in Google Chrome? In other browsers everything is OK.

Here is the website: https://meinerdi.github.io/ . All the attributes are correct, the resources have left only one file format, webM, and still does :(

All the question is solved. It turns out that in the latest update Chrome the autoplay does not work without muted.
