paulc: One action item to implement proposal 2b
ACTION-1?
<trackbot> ACTION-1 -- David Dorwin to and editors to implement proposal 2b by revising EME specification -- due 2012-07-17 -- OPEN
<trackbot> http://www.w3.org/html/wg/media/track/actions/1
paulc: status report?
ddorwin: didn't get through all the changes necessary - made progress but not finished
paulc: we'll look at the due date later in the agenda
http://dvcs.w3.org/hg/html-media/raw-file/tip/encrypted-media/encrypted-media.html
ddorwin: editor's draft is updated - minor bugs updated and removed issue list since these are now in bugs
paulc: how do i see old versions?
ddorwin: list at the bottom of the document
http://dvcs.w3.org/hg/html-media/
ddorwin: This shows the files and the revisions
paulc: two main bugs 16612 and 16613
https://www.w3.org/Bugs/Public/show_bug.cgi?id=16612
https://www.w3.org/Bugs/Public/show_bug.cgi?id=16613
paulc: in the last meeting we
decided to adopt proposal 2b
... is the short story that you're not done and that you need
more time?
ddorwin: yes - it's a major
effort to update everything because this affects all the
algorithms
... so what I'm proposing is to start making the changes and
include a link in the top of the spec to the last stable
version
paulc: can you do this in stages?
ddorwin: doing it in stages is
one option to allow discussions to continue
... i don't think i'll be able to do all before the next
meeting
... but we could include the API changes so that we can discuss
those specifically
paulc: when will you be away?
ddorwin: next week and through the meeting the following week but i'll try to dial-in
paulc: so you're trying to do some this week?
ddorwin: correct
paulc: what can you get done this week?
ddorwin: updating section 2 and
2.1 and 3
... section 4 would be commented out pending the next
discussion
... section 5 probably not done and some of the examples
paulc: there are three editors on the spec - are you doing most of the lifting here?
ddorwin: yes
paulc: is there a chance you and
the other editors can work out a plan this week so they can
continue while you are gone?
... sorry to out this out loud but this seems like the obvious
question
markw: normally i'd be happy with that but i'm also out
paulc: i guess this is taking
longer than originally thought
... we can do some work this week but that might not give us a
document that will allow us to make progress
... the meeting after the next one i will be away
... i don't want to wait 6 weeks
... should we cancel the aug 7 meeting and keep the aug 24
ddorwin: i think that's fine
adrianba: i agree
paulc: so the strawman is to move
the action to be aug 17?
... does that make senses?
ddorwin: yes
ACTION-1 due aug 17
<trackbot> ACTION-1 And editors to implement proposal 2b by revising EME specification due date now aug 17
paulc: this will give people one
week to look at the spec so we can pick up from there
... would be good for the editors to enumerate the changes on
the list and ask for feedback
... and if there are parts that weren't changed then not
that
... don't block on parts that you aren't sure how to change and
be transparent on the list about where people should focus
their efforts
... is there a reason to look at agenda 5b on key release?
ddorwin: i think it's fine to continue to discuss this - it's not totally dependent on the O-O change
<paulc> http://lists.w3.org/Archives/Public/public-html-media/2012Jul/0070.html
ddorwin: key release is section 4
in the original proposal
... and i was trying to get more discussion on what it should
look like
... object oriented seemed to solve most of that
... there seemed to be some issues related to browser use that
make this difficult
... and i wanted to start a discussion on this
... since it is independent of the API
markw: i think david is quite right in his mail
<paulc> Mark's response: http://lists.w3.org/Archives/Public/public-html-media/2012Jul/0071.html
<mark> we need a synchronous method to fetch key release messages which could be used in onclose methods
paulc: do we just need more people to comment?
ddorwin: yes, especially on the sync API and whether that's a good idea and how it would work
<mark> but generally, these cases are handled by the CDM keeping the key release messages until it gets the ack from the server, even if this means keeping them hours or days
paulc: thought it might be useful to discuss the most recent bug
https://www.w3.org/Bugs/Public/show_bug.cgi?id=17750
paulc: there hasn't been much
progress on bugs
... but i guess people are waiting for the principle bugs
related to O-O
... is it worth looking at this
ddorwin: this is a bug that
escaped being filed previously
... i added the bug as i removed it from the issues list in the
spec
paulc: which of these 5 bugs
would it be useful to have some discussion on today?
... it may be that these just need to be held in our queue
ddorwin: i think 17673 and 17682 might be interesting
paul: lets start with https://www.w3.org/Bugs/Public/show_bug.cgi?id=17673
Define Initialization Data for implementations that choose to support the ISO Base Media File Format
<paulc> "Define Intialization Data"
paulc: is there a proposed solution
ddorwin: background - we need a
common expectation of what initdata is for the different file
formats
... ISO and CENC is probably the most interesting since it is
the most complex
... there are options about which data to send
... looking for people with more experience with ISO
paulc: you're looking for someone to take ownership?
ddorwin: yes, adrian or mark should do that
markw: i'm happy to take this
one
... i think the initdata will contain all the information
(first option)
... unless the key system is already selected in which case UA
could filter them down
paulc: can i give you an action item to propose a resolution by aug 17?
markw: i'll try to do it before i leave
<trackbot> Sorry, couldn't find user - markw
<scribe> ACTION: mark to propose a resolution to bug 17673 [recorded in http://www.w3.org/2012/07/24-html-media-minutes.html#action01]
<trackbot> Created ACTION-2 - Propose a resolution to bug 17673 [on Mark Watson - due 2012-07-31].
paulc: next https://www.w3.org/Bugs/Public/show_bug.cgi?id=17682
Clear Key: Document how keys and key IDs are associated
ddorwin: this relates to addkey
with initdata which assumed that initdata was the key id but
this doesn't work for ISO CENC
... we need to figure out how we want to support ClearKey
... for non-ClearKey there is a license format
... we need to figure out if we concatenate things or set size
limits
... or maybe define ClearKey in a different way
... so looking for feedback on how to proceed
<scribe> ACTION: adrianba to propose resolution to bug 17682 [recorded in http://www.w3.org/2012/07/24-html-media-minutes.html#action02]
<trackbot> Created ACTION-3 - Propose resolution to bug 17682 [on Adrian Bateman - due 2012-07-31].

paulc: if we look back at item a
(17658) which we discussed in the last meeting
... this item hasn't received much additional discussion
... propose to carry this forward in the agenda
http://www.w3.org/2012/07/10-html-media-minutes.html#action02
paulc: moving along - there is lots of work for the editors
paulc: any other business?
paulc: we will cancel the Aug 7
meeting
... i will keep up the biweekly schedule
... i'm unavailable for aug 21 - i will work with the editors
and co-chairs and maybe the Team to find someone to stand in
for me in that meeting
paulc: adjourn early today - have
a bunch of actions
... we should realise that in July/Aug some things slow down
due to vacations
... thanks to david for all the help on the call today
... we're adjourned
