Correct.
Since the manifests refer to "other files in the same directory", the
same md5sum value will apply to them all, and the client should just
ask for the correct thing each time.

More or less, yes. The first line there would probably be:
location ^~ /vod/ {
but the rest looks right. You'll want to change the secure_link_md5 line
to match what you want, of course.

One way to set all of the variables at once (assuming the request is
well-formed) would be something like:
map $request_uri $the_md5 {
default "";
~^/vod/(?P<one>[^/]+)/(?P<the_time>[0-9]+)(?P<the_directory>.*)/(?P<the_file>[^/]+)
$one;
}
where "$the_md5" becomes "all of the non-slashes after /vod/", $the_time
becomes "all of the numbers after that", $the_directory becomes
"everything else up to the last slash", and $the_file is "everything
after the last slash".
You will probably want to change things such that "/hls" is either
excluded from $the_directory, or excluded from the rewrite directive.
You can check the debug log, or temporarily do things like
return 200 "md5 = $the_md5; file=$the_file;\n";
to see what values the variables have when you are testing.
You can use "curl" to make a test request and see whether the response
is what you expect.
Good luck with it,
