MoQT Issues (Ian Swett, 50 min)

FIN/RESET_STREAM etc for SUBSCRIBE (Martin: https://github.com/moq-wg/moq-transport/pull/589)

Ian Noted that PR #593 may make Martin's PR #589 much easier
to understand.

Ian will do an editorial pass. Expect to merge #589 end of the week. So
any last minute feedback please provide it by friday.

Alan raised the issue that there are inconsistency if an relay can
remove objects in the middle of a sub-group? The meeting discussed and
attempted to clarify this.

The meeting believe there is agreement on how it should work in the
error free case, but there might be edge cases that needs more precise
definition. If a subgroup contains objects 2,4,6,8,10 and if object 6
times out, then the remaing objects (8, and 10) will not be delivered.

Cullen requested that Alan help him clarify PRs #565 and #587

Priority Clarification (Alan: https://github.com/moq-wg/moq-transport/issues/585) vs. Victor (https://github.com/moq-wg/moq-transport/pull/518)

Martin made a poll: 3 for Victors, 2 for Alans.
Indication that people want to make a choice, not stay with what exists.
More discussion required.

The meeting attempted to determine what are the core differences and
especially how to handle changing priorties both of track level and in
subgroups.

No conclusion
Alan and Victor will discuss their differences.
