Just a user, this will be a good feature.

This patch doesn't seem to work with say -

http://dash.edgesuite.net/akamai/bbb_30fps/bbb_30fps.mpd

Of course that base url is ./ - but I can change that or I can
grab the content and make a local setup to match.

Either way this doesn't seem to replace $Number$ properly/in time so I
get an error.
