Candidate FPWD

<paulc> EME candidate FPWD: https://dvcs.w3.org/hg/html-media/raw-file/tip/encrypted-media/encrypted-media-fpwd.html

co-chairs are currently discussing over email

adrianba: Haven't updated the FPWD document yet. Will updated from the editors draft once we are ready to move forward

paulc: If we were to use the Editor's Draft would it also have the current issues outline in it.

adrianba: yes

ddorwin: Current fpwd only has one issue in it. The Editor's draft has 3 now.

<paulc> paulc: When the Chairs decide the next steps we may ask for an update candidate FPWD

EME Bugs

paulc: I enumerated all bugs that were received after the EME CFC.

<paulc> Maciej's response: http://lists.w3.org/Archives/Public/public-html-media/2013Apr/0093.html

Want to discuss Maciej's response

<adrianba> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20960

paulc: I want to know how people want to deal with each of these items'

adrianba: Already was resolved as WORKSFORME, but it got reopened. Concerned about worrying about how the bug was specifically resolved.

<joesteele> +1

<paulc> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20963

paulc: Bug 20963 was resolved and then reopened without new information.

adrianba: The bug was resolved and reopened several times. Gave up on closing it. Would like the chair's help here

paulc: Taking an action to resolve the bug as NEEDSINFO
... Will point out that the bug should not be reopened without new information

<paulc> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21016

ddorwin: I reopened this

adrianba: Objects to reopening the bug since they are not actionable.
... I don't want to have to worry about which ones we need to keep open just because we are going to address it later.

glenn: Agrees with adrianba

paulc: Do you have a concrete proposal for how to move forward.

<paulc> Proposal: File issue related bug Bug 21016 and mark 21016 as RESOLVED

adrianba: File an issue in the tracker that defers considering removing the clearkey section until later when we have implementation experience

<paulc> EME bugs: http://tinyurl.com/7tfambo

paulc: Wasn't planning on going into detail on there today. Just want to get a sense of where we are.
... Currently 34
... Assuming editors are continuing to working on these based on the f2f discussion.

ddorwin: Yes. adrian and I closed 10 or so since the f2f.

<ddorwin> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21854

<ddorwin> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21855

ddorwin: Later is related to not firing needkey if you already have the keys

<joesteele> https://www.w3.org/Bugs/Public/show_bug.cgi?id=19788

joesteele: Is Bug 19788 resolved now?

<paulc> See https://www.w3.org/Bugs/Public/show_bug.cgi?id=19788#c13

ddorwin: Was resolved yesterday. TODO was moved to ISOBMFF bug

paulc: Editors w/ keep processing bugs.

ddorwin: Event and state transitions bugs need to be addressed first. Many other bugs depend on them

MSE status and bugs

<paulc> Editor's draft (Apr 30): https://dvcs.w3.org/hg/html-media/raw-file/tip/media-source/media-source.html

paulc: Only 4 bugs outstanding

<paulc> MSE bugs: http://tinyurl.com/6pdnzej

adrianba: Bug 21819 & Bug 21328 are just some terminology discussion.

<paulc> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21819

<adrianba> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21328

acolwell: Thought dropping compressed was sufficient.

adrianba: It was clear that Pierre agreed.

paulc: Pierre do you with to comment.

pal: Concerned that MSE can applied to baseband signals so the use of coded is misleading.

<paulc> Glen proposed: ""A unit of encoded media data that has a presentation timestamp and decode timestamp."

<paulc> code frame -> essense frame is used in some places

<paulc> Pierre can live with just getting rid of "compressed". Editors will now deal with 21819 and 21328

<adrianba> https://www.w3.org/Bugs/Public/show_bug.cgi?id=21431

adrianba: Just waiting on text from Glenn

<adrianba> https://www.w3.org/Bugs/Public/show_bug.cgi?id=20901

glenn: Hope to get it posted today or tomorrow. Will definitely have it before next meetin

adrianba: Last one is how we deal with out of order appends. Discussed at f2f.

<paulc> F2F progress noted in https://www.w3.org/Bugs/Public/show_bug.cgi?id=20901#c4

<paulc> Editors to propose new solution

<Zakim> adrianba, you wanted to comment on the other 2 bugs

paulc: There was discussion at the f2f about creating the primer. Chairs will send out an announcement sometime this week.
... Which spec do we want to discuss next week. Bug count implies EME

<adrianba> http://lists.w3.org/Archives/Public/public-html-media/2013Apr/0101.html

ddorwin: Yes lets discuss EME next week.

<paulc> Doug's request: "I'm looking for people who can help create a reference article and tutorial, so that it is factual and informative, and adds to the discussion."

<paulc> Doug: Is there someone in one of the member companies represented here that could help produce such "reference article or tutorial"?

<paulc> Adrian: Maybe since MSE is more mature we could consider getting documentation on MSE on webplatform.org?

<paulc> Doug: I am looking for material to help people understand 'content protection".

<adrianba> who is the "we" in "what we're looking for"?

<Zakim> adrianba, you wanted to discuss another topic before we run out of time

<pal> pal: MSE is a complex specification. Testing will be beneficial

pre-last call

adrianba: Discussed at F2F.

<paulc_> Paul to send out pre-LC notice with date out 3 weeks

adrianba: I want to get that process started.

<paulc_> The pre-lc notice is for MSE

<paulc_> Paul will announce a pre-Last Call with a deadline date out 3 weeks.

<paulc_> All bugs filed before the deadline will be processed BEFORE we enter LC.

<paulc_> All bugs bugs filed after the deadline will be process as part of the LC ie they become LC bugs

<adrianba> During the pre-LC period, bugs filed before the deadline will be processed before LC - there maybe a gap between the pre-LC deadline and the LC announcement while we address those bugs

<adrianba> At LC, the working group is supposed to declare that it is done, no new features should be added during LC

<adrianba> The pre-LC is to make sure the WG believes the document is complete

pal: Once last call happens. What is the next step?

<paulc_> This kind of pre-LC helps make the entry into LC more deterministic.

paulc_: When we go into LC we have to raise the bar for how we handle bugs
... If we get minor changes then we proceed to call for implementations

paulc: If we get major changes then we have to start another LC.

<glenn> time?

adrianba: Requesting that we add an agenda item to the next call discussing the process. Since we are out of time

<adrianba> ISSUE-1?

<trackbot> ISSUE-1 -- Consider moving the Clear Key definition into a separate specification -- raised

<trackbot> http://www.w3.org/html/wg/media/track/issues/1
