[enhancement] Add support for other sites (HTML5)

[diogomsantos]

Is it possible to add support for other websites with html5 videos ? youtube-dl supports many other sites, and this would be great for the Raspberry Pi.

Thanks

Hi sorry, missed this issue.

Yeah for sure it's simple to do - I don't have time atm but PRs are always appreciated ;-)

If I get time soon i'll take a look!

Matt.
