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.
