The methods that use cout are only for debug, currently they are not called
somewhere. Anyway I have changed them to msg_Dbg or removed. I don’t use the
msg_Dbg that often due to the fact that it needs a vlc_object.

The current version of the standard is of course different to the version
proposed here because I have written it last year where DASH was WD,
currently it is DIS. But the overall structure is the same they have changed
some names and introduced some new elements, attributes, mechanisms and
profiles (special things for ISOBMFF or MPEG2-TS). That was foreseeable
therefore I have tried to make the plugin that flexible as possible. I think
it is a good starting point as it is and it should be relatively easy to
extend/modify the XML part. The profile that is usable with the plugin is
described here [1] and is an extension of the isoff-basic-on-demand profile.

Yes if I have not overseen something.

Changed every unsigned int to size_t this should fix the problem.

BR and Thanks for the input Frederic/Remi
