Add custom video player example

[sfc-gh-kbregula]

Hello,

I wrote a simple example of a component that passes a URL address of a file to a custom component. This is based on a private API, so it's more of a discussion of the custom component's API than the actual code we're going to merge.

Best regards, Kamil
