Agenda+ Assign Roles
Chair: Nigel Megitt
Scribe: [to assign during meeting]
Regrets:
Activity since last meeting: IMSC issues discussed
Agenda+ Prioritise discussion for this meeting
Check-point for order of topics – I'd suggest:
1. MIME codecs parameter if we're quorate on this topic
2. Profiles and features (change proposal 12 etc), with
extensions/restrictions etc as recently added,
3. TPAC F2F,
4. SMPTE liaison,
5. Change proposal 2,
6. Pending Review issues,
7. Change proposal 7,
8. I can't believe we'll get this far!
And stop when time runs out – I'm happy to set and impose time limits on
these topics if members would like to take that approach.
Agenda+ MPEG liaison re MIME Codecs parameter
This is scheduled for a major discussion for this topic since all main
contributors will hopefully attend.

Agenda+ Change Proposals – progress and review
Change Proposal 12 [7] has not been updated but Glenn has made changes that
address many of the issues in there [7].
Can we agree to set the default @validationAction to "warn" and make it a
recommendation to the validator rather than mandatory?
Change Proposal 2 [6] has been implemented and has been pending review for
over 1 month
Can we mark as CLOSED – IMPLEMENTED?
Change Proposal Index is at [5].
Which Change Proposals would owners like to progress next? There are 20 open
CPs.
Timeline updated in 13th Mar meeting:
January-March: Clean up and complete CPs
April-July: Draft, iterate and edit solutions to CP issues
August: Last Call
