Third issue, non active mixer sessions...

The representation of the information is assumed to be the
same as the one for active sessions. We chose to report
separately encodings and decodings as well, which should
provide interested ASs with the proper (estimate)
information on available codec instances. This would also
allow licensing information to be reported accordingly (e.g.
a MS might have a license that only allows decoding for a
codec but no encoding, and as such the available encoding
instances would be 0). Of course, as we all agreed in SF and
on the ML, this reporting is assumed to be a (hopefully good
enough) estimate of the available resources.

Do you think this representation suits the requirements for
this functionality? Or would you suggest something
different?

Thanks,
Lorenzo and Chris
