Oh. The answer is probably pretty simple: I bet that Skype built their new
version with support for the V4L 2 API rather than the long-deprecated version
one API.
Alternately, they could have implemented the same work-around internally, or
even linked in the compatibility code[1], or written dynamic detection for the
two API versions, or....
So, lots of ways. This being a closed application you can't really know.
