paulc: done
paulc: there are 4 of these
... one of them had a lot of discussion but the others not so
much
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24771
<paulc> https://www.w3.org/Bugs/Public/show_bug.cgi?id=24771
paulc: long proposal here - do you just want to add this to the list of things of comments or should david introduce the issues?
ddorwin: issue came up when deciding when to GC the objects - could be a circular reference meaning things wouldn't get collected
paulc: volunteer to review?
<markw> I will review it too, but I am also not a browser vendor
joesteele: i could review but not sure if my input would be as useful - not a browser vendor
paulc: perhaps someone from Microsoft can take a look at this
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24873
paulc: filed recently - does this fall into the same category?
ddorwin: not being able to detect if the browser has capabilities needed - adrian mentioned this in one of the other bugs
<joesteele> +q
ddorwin: first two paragraphs
says what it is - the rest says why
... two changes - one if to add capability string and the other
is changing the return type to have three states
... somewhat like canPlayType though doesn't have to be
... those are independent but work well together
joesteele: seems to reintroduce
something we discussed at the beginning
... decided early on the key systems shouldn't have this info
because it was too complicated
ddorwin: some of the same issues
but this is more targeted specifically at audio vs video
... but we decided not to 'abuse' the key system name
joesteele: maybe i'm not
understanding capability - do you mean things like HDCP
... is this something where this platform is not at all capable
or not right now
... because if not right now then you'd need to call again
ddorwin: no, i wasn't thinking
about HDCP which can take a couple of seconds
... this is supposed to return quickly
... many key systems support multiple levels of robustness
<ddorwin> The old capability detection bug: https://www.w3.org/Bugs/Public/show_bug.cgi?id=16611
adrianba: not sure what the capability string contains - what if it is more than one thing - should it be a string or something else?
ddorwin: it is key system
specific - could have a key system specific separator
... could have an array of strings but just as easy to be comma
separated
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24874
ddorwin: result of
isTypeSupported doesn't say if it works with MSE or with
src=
... filed to track this issue
paulc: questions?
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24904
paulc: provided the beginning of the march part of the thread
http://lists.w3.org/Archives/Public/public-html-media/2014Mar/0002.html
paulc: most recent suggestion to raise this as a TAG issue
<joesteele> +1 to email discussion
paulc: shall we let this continue in email? this problem exists in other places too
paulc: all the bugs that had
postings since our last meeting
... agenda item 7 includes implemented bugs since last time (4
bugs)
... agenda item 8 is bugs waiting for editors (6 bugs)
... agenda item 9 is low pri bugs
... plan to step through the items in #6 and ignore the others
today
https://www.w3.org/Bugs/Public/show_bug.cgi?id=17673
adrianba: we think we should move
ahead with changing this as discussed in recent meetings to see
if people like the text
... (that's Microsoft's position)
<joesteele> no objection
paulc: any comments?
... any objections to trying this out?
... okay, this one is assigned to the editors to do
adrianba: i'm happy to make the change
ddorwin: i'll file a specific bug about the "CENC" string - i suspect we'll need to change isTypeSupported too
https://www.w3.org/Bugs/Public/show_bug.cgi?id=17750
paulc: comment from adrian on feb 21
<joesteele> +q
adrianba: we reviewed this and think we're proposing the correct answer - we need someone to check our working
ddorwin: no specific objections
markw: looks okay - i will check with our implementers
joesteele: i had raised a
question above about cached keys being released
... not clear to me that we agree that keys can be cached
... might be off topic for this bug
adrianba: i think loadSession
implies there are cached keys otherwise what could you
load
... i think there is a question beyond just consistency with
other specs - we proposed a solution that does impact what
order things can execute in
... so there is something EME specific to review here too
glenn: haven't looked at the detail but curious if there is a need for promises here?
<ddorwin> Does the proposed spec change related to spinning the event loop mean MediaKeys construction will prevent any other tasks (from any other spec) from being processed? Is that desirable?
adrianba: i don't think promises apply here - this is about multiple async tasks interacting with each other
<glenn> sleep(0)
adrianba: spinning the event loop is like VB6 DoEvents - it lets other things run
paulc: is there an editor to implement this?
adrianba: i can do this
https://www.w3.org/Bugs/Public/show_bug.cgi?id=21798
adrianba: we can live with not solving this in this version but if someone comes up with a workable proposal then we are okay with that
ddorwin: i will make a proposal
https://www.w3.org/Bugs/Public/show_bug.cgi?id=23619
<ddorwin> Open issue in DOM4 on the future of DOMError: http://www.w3.org/TR/dom/#interface-domerror
adrianba: while the spec
continues to have DOMError, we think we're using it
correctly
... we also prefer to keep systemCode
<joesteele> +1 to keeping it in the spec as-is
ddorwin: i don't object to system code and the inclusion requires that we define an additional type - if people want to keep it then that is fine - it is already in the spec
paulc: what is next?
ddorwin: if nobody wants to eliminate this type then we resolve, fixed
paulc: proposal is to mark it fixed
<ddorwin> done
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24027
paulc: mark agreed to add a
concrete proposal - in comment 6
... some dialogue here - what is the current state?
markw: i didn't see the questions from joe and david so i need to catch up and reply to their points
joesteele: i should reply in the bug - i wasn't clear from david's last question why you wouldn't want to use the MAC - i would guess that the CDM would say key not available
ddorwin: some confusion about what the MAC was earlier in thread - agree - question is do the existing algorithms deal with this
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24419
paulc: is this ready to move to the "to be implemented" list?
ddorwin: need to implement the license request format first
https://www.w3.org/Bugs/Public/show_bug.cgi?id=24673
ddorwin: we find that the content
type and the codecs have different requirements
... so we might need non-normative text
adrianba: seems fine - just need text to add
paulc: do we need concrete text in the bug or just move forward - better to move ahead
ddorwin: will make this dependent on the "CENC" bug that I said I will file
paulc: i said we'd skip the other
bugs unless someone objects - now is the time if you want
to
... in 10 days i'll evaluate where we stand for the topic bugs
for discussion in the next meeting
adrianba: different topic, are people planning to attend the F2F meeting to discuss EME?
<markw> yes, I'll be there
<BobLund> I'll be there
paulc: [lists attendees from TF who already plan to attend]
<paulc> https://www.w3.org/2002/09/wbs/40318/html-april-2014/results
paulc: if you can't attend might be helpful to fill out the registration form saying so
joesteele: i may have a conflict - probably be on the phone at least
ddorwin: would be nice if we knew which day to minimise travel
<paulc> https://www.w3.org/wiki/HTML/wg/2014-04-Agenda#Potential_Topics
paulc: if you put it on the
potential topics list then we can reserve that time
... meeting is tues/wed
<BobLund> Tue or Wed AM
<paulc> April 8-9
paulc: does anyone have a pref for which day
johnsim: if the meeting is wed AM i might be able to attend
paulc: any objections to wed AM?
<BobLund> Wed AM is good
adrianba: works for me
paulc: would it be worth asking dsinger about attending?
pal: excellent idea
paulc: i'll propose on the draft
agenda - should i ask for 9 to 11?
... i'll figure this out
paulc: talk to you in 2 weeks
