15:08:00 TOPIC: Items from last meeting
15:08:14 TOPIC: Bug 19809 - Specify which portion of addKey() algorithm to run when updating license for a key
15:08:20 https://www.w3.org/Bugs/Public/show_bug.cgi?id=19809
15:08:43 paulc: david was to evaluate the proposal
15:08:58 ... last comment is from david this morning
15:09:12 +ddorwin
15:09:23 https://www.w3.org/Bugs/Public/show_bug.cgi?id=19809#c5
15:10:13 paulc: it looks like the action has been done but not in a state to close the bug
15:10:36 ddorwin: question is should we always try to resume playback if we get an update call and playback is stopped
15:10:47 ... this is simplest and could be correct
15:11:11 ... hard to specify "did store key"
15:11:44 ... proposal is to remove key storage algorithm, provide non-normative guidance, remove did store key flag
15:11:49 paulc: comments?
15:12:17 ... no comments - think we should resolve this bug and if people see text they don't like they can re-open
15:12:26 ddorwin: okay, will continue editing today
15:12:43 TOPIC: Bug 17202 - Explicitly document how keys are to be shared
15:12:48 https://www.w3.org/Bugs/Public/show_bug.cgi?id=17202

15:12:57 Proposal in http://lists.w3.org/Archives/Public/public-html-media/2013Oct/0031.html
15:13:06 paulc: joe isn't here today
15:13:13 ... not sure what to do about this
15:13:19 ... there have been 5 comments on this
15:13:26 yes
15:13:43 ... how do we want to handle this given joe's absence
15:13:47 +1 to needing more discussion
15:13:55 ddorwin: need more email discussion
15:14:05 TOPIC: Bug 17682 - Clear Key: Document how keys and key IDs are associated

15:15:20 ddorwin: didn't do this yet
15:15:47 paulc: no outstanding questions - can just be resolved
15:15:59 TOPIC: Bug 21855 - Avoid network traffic and duplicate sessions for the same key(s)

15:17:04 paulc: is this related to ACTION-40?
15:17:11 ddorwin: not sure what the relationship is
15:17:33 paulc: this can be resolved as a result of the discussion last time?
15:17:39 ddorwin: i think adrian owns this
15:18:20 ACTION: adrianba to complete work on bug 21855
15:18:20 Created ACTION-47 - Complete work on bug 21855 [on Adrian Bateman - due 2013-11-05].

15:19:05 adrianba: didn't get to this yet
15:19:24 TOPIC: Bug 17673 - Define Initialization Data for implementations that choose to support the ISO Base Media File Format
15:19:31 https://www.w3.org/Bugs/Public/show_bug.cgi?id=17673
15:19:38 paulc: john and david were going to discuss this
15:20:07 johnsim: i got an email from david describing his concerns - we don't have new text yet - i agree with his concerns and they make sense so we need to come up with new language
15:20:15 paulc: the next time this group meets is the F2F
15:20:44 ... for items still open, not things just waiting editing, i want actions to follow-up before the meeting
15:21:00 ACTION: john to draft a proposal for bug 17673
15:21:00 Created ACTION-48 - Draft a proposal for bug 17673 [on John Simmons - due 2013-11-05].
15:21:13 ACTION-48 due in two weeks
15:21:13 Set ACTION-48 Draft a proposal for bug 17673 due date to 2013-11-05.
15:21:33 TOPIC: Bug 20991 - MediaKeys constructor: make CDM loading asynchronous and fix the load failure algorithm
15:21:43 https://www.w3.org/Bugs/Public/show_bug.cgi?id=20991
15:22:11 paulc: adrian said he had made the changes and people were going to look at this
15:22:15 ... resolved fixed
15:22:16 I reviewed it. It's fine with me.
15:22:20 ... don't think we need to do anything here
15:22:36 TOPIC: Bug 23618 - Drop "key" prefix from event namesEvent name proposal
15:22:43 https://www.w3.org/Bugs/Public/show_bug.cgi?id=23618
15:23:46 paulc: this bug and the next one was to reflect changes proposed in email
15:23:52 David's email: http://lists.w3.org/Archives/Public/public-html-media/2013Oct/0015.html
15:24:04 ddorwin: bugs are just what was in the mail
15:25:18 q+
15:25:28 ddorwin: proposing to remove the key prefix from events
15:25:40 ack jd
15:25:52 ... not always related to keys so may be confusing
15:26:07 jdsmith: this doesn't match our implementation - don't see a strong argument for changing at this stage
15:26:50 ddorwin: Microsoft's implementation is prefixed so that will have to change anyway
15:26:58 jdsmith: is this aligned with something else?
15:27:18 ddorwin: we're firing at a mediakeysession so key seems redundant
15:27:24 ... media elements have error event
15:27:51 ... more than shorter names, as we've got to the state machine there are many other things that can cause you to be ready
15:28:31 jdsmith: seems unnecessarty
15:28:54 paulc: if the APIs are prefixed then you still have to change?
15:29:15 ddorwin: applications will have to update to drop prefixes
15:29:18 ... and make other changes
15:29:40 jdsmith: i imagine we can pick this up when we unprefix the API
15:29:52 paulc: sounds like you can live with this but won't make the change soon
15:29:57 jdsmith: it will be a while
15:30:09 paulc: any objection to the changes david is proposing?
15:30:16 paulc: don't hear any
15:30:30 paulc: think we should mark this as implementable
15:30:43 ACTION: ddorwin to implement bug 23618
15:30:43 Created ACTION-49 - Implement bug 23618 [on David Dorwin - due 2013-11-05].
15:30:52 TOPIC: Bug 23619 - Drop or change MediaKeyError constant prefix
15:31:00 https://www.w3.org/Bugs/Public/show_bug.cgi?id=23619
15:31:35 ddorwin: similar to the previous one - we prefixed the constants to fire errors
15:31:51 ... this isn't consistent with other things
15:32:04 ... not sure what to suggest - it was suggested that we use enum strings
15:32:37 paulc: can we use this in WebIDL
15:33:19 adrianba: enum strings are defined and commonly used - not sure about with errors
15:34:05 ACTION: adrianba to work on proposal for bug 23619
15:34:05 Created ACTION-50 - Work on proposal for bug 23619 [on Adrian Bateman - due 2013-11-05].

15:38:37 paulc: jerry, are you willing to take an action to write a proposal on this?
15:38:48 ... may mean starting an email thread - want someone on point

15:45:42 ack ad
15:47:04 adrianba: i proposed that resolving bug 17550 would include the things mark was requesting and maybe we could then resolve bug 17199
15:47:09 ack dd
15:47:34 ddorwin: was going to say something similar - should make the changes to 17550 and then see if there are any gaps - made this bug dependent on 17550
15:48:08 ACTION: markw to propose how to resolve bug 17199 in light of resolution of bug 17550
