How i can use in vaadin 14, it’s possible?
The AudioVideo add-on has been made for Vaadin 8 and does not work with Vaadin 14 as is without major rework. However I have tested that the add-on works with Multi Platform Runtime product that allows to use Vaadin 8 components with Vaadin 14.
One of the major features in the add-on is the support for range requests. In Vaadin 8 it was possible to override component specific request handling. Thus it was possible to implement this in add-on.
In Vaadin 14 it is no longer possible to do this in same way as it was in Vaadin 8. There is a feature request to add support for Content-Range in Flow here https://github.com/vaadin/flow/issues/7465
