oEmbed / Vimeo: Support player.vimeo.com-style URLs

[danielbachhuber]

Vimeo also supports URLs like ​http://player.vimeo.com/video/64213430 for its oEmbed endpoint. It would be nice if the core regex also handled these URLs.

player.vimeo is their old URL - ​http://vimeo.com/help/faq/sharing-videos/embedding-videos#can-i-embed-my-video-on-an-https-domain - How much is this used that it's still needed?

[danielbachhuber]

Sorry, I don't remember the original context in which this came up.

I don't know if they're still used, though they still work. ​http://player.vimeo.com/video/85152562.

If we can find them in use, we should support them. If they're no longer used, I don't think it's worth it.

I found a handful of reports in the forums about this exact problem, so since Vimeo is phasing it out, I think it's a coin toss here :/ So few people appear to have this problem. I think we should patch it, since it's rare enough that if it does happen, the odds of someone recognizing why AND knowing the 'fix' is to use the non-player URL would be rarer.

I didn't realize vimeo was already a regex. No harm in just allowing any subdomain.

In 27225:

Allow any vimeo.com subdomain for embeds.
