Add oEmbed Support for Streamable

[paulschreiber]

Streamable ​https://streamable.com/ is a video hosting service. It's not among the list of whitelisted oEmbed providers. It would be good to add it, so embedding videos from Streamable is as easy as pasting the URL, similar to how embedding a YouTube video works.

Could you please go through the ​checklist for whitelisting oEmbed providers, the basics are that they must

• be well-established, popular, and mainstream services,
• properly and fully implement the oEmbed specification,
• and clearly be a trusted provider.

This is the first I've heard of them, which may be a reflection on me rather than the company ;)

Looking at their oEmbed endpoint, they could meet the auto-discovery requirements by removing the allowfullscreen attribute from their iframe. Basic tests show the embed still works without it so it may be worth logging a ticket with their support team.

This ​ticket was discussed during a triage session in the WordPress Slack.

I'm going to close this ticket as maybe later as it seems the service is popular on a few sites but hasn't reached the level of use required to be whitelisted.

If the service breaks through to the mainstream then the whitelist request can be reconsidered then.
