Yes, but: what happens when you try it?
On a test system:
location /vod/ {
return 200 "one is $one; the_md5 is $the_md5;\n";
}
and request something like /vod/abc/123/hls/def/ghi.html
I think that the best way to learn and understand nginx, is to use nginx.

Mostly correct.
"map" will compare its first argument (in this case, the expansion of
the variable $request_uri) with all of the "key" entries in its third
argument (the map) -- in this case, just one regex and one default.
If the regex matches, all of the (?P<>) named variables are populated
(because that's what a regex does).
Then "map" will set the variable named in its second argument ($the_md5)
to the matching value in the map -- which is the value of $one, in
this case.
So - it is the regex engine that sets the value of $one (and $the_time,
etc); and then "map" sets the value of $the_md5 to the current value
of $one.
