It sort of is in Firefox, actually.

It fails 2.1.2, No Keyboard Trap, in all browsers, anyway.
http://www.w3.org/TR/UNDERSTANDING-WCAG20/keyboard-operation-trapping.html

It's not a matter of whether the YouTube player itself conforms,
but whether a web page with it embedded can conform.

Appendix B Documenting Accessibility Support for Uses of a Web
Technology
<http://www.w3.org/TR/UNDERSTANDING-WCAG20/appendixB.html> says:

"The documentation includes version-specific information about
all the assistive technologies and all the user agents and the
ways that they interact with one another. If support in these
user agents is similar, it will be straightforward for an author
to decide if a documented way of using a technology is
accessibility supported. If the uses supported are different in
different versions, authors can only rely on the uses that are
supported in the versions available to their users in determining
accessibility support."

Conformance, then, would be user agent specific, were it not for
2.1.2 -- which it fails everywhere.

That page also says:

"If a way of using a technology is not relied upon for
conformance, the absence of accessibility support for that use
does not prevent conformance of the Web page. So if the
unsupported use does not occur in the content, or if there is a
conforming version of that content available, the Web page still
conforms. For instance, lack of accessibility support for
interactive controls in a Web technology would not prevent uses
of the Web technology for non-interactive content that are
accessibility supported."

There are web page which embed the youtube player with accessible
controls, and those pages conform.
