Unfortunately only with a great deal of difficulty.
The "?v=..." and "/embed/..." URLs are just public identifiers to access
the YouTube APIs. At the HTTP level they result in a quite long series
of sub-requests, redirections and the like bouncing all over the
youtube.* and googlevideos.* and googleapis.* domains.
Yes all of them are involved multiple times. So whitelisting is an
all-or-nothing prospect, with other G services being implicitly
whitelisted as side effects.
Also, whenever the way to decipher the above maze of traffic gets
published so we can do things like what you ask. YT shortly afterwards
change how it operates - usually towards even more complexity. This has
happened too many times to be coincidence IMO.
