Dear all:

I met a issued DASH live link & the root cause is it has a minimumUpdatePeriod
by "PT5s".

Please be aware of the 's', it is case sensitive now in current parsing flow.

It means if we have a 'S' everything will be O.K but 's' fails instead.

I am not sure if ISO-23009-1 defined the format well but just see the format
definition for xsd:duration as the links below.

They both say 's' is legal.


Besides capital letters, Should we support small letters also?

Thanks.
