Mike Smith added Safari results in http://w3c.github.io/test-results/media-source/all.html

Firefox results as well and lost a Chrome set of results
... Lots of time outs for Safari - could be a test runner
problem, or a special flag is needed
Close ACTION-97

Update from Matt: https://lists.w3.org/Archives/Public/public-html-media/2015Jun/0040.html
Matt: I have been asking about the WebIDL possible problems
[Chromium] MSE w3c web-platform-tests interface.html shows multiple unexpected failures: https://code.google.com/p/chromium/issues/detail?id=504170
paulc: Matt's work has been
concentrated on generates "columns" of results for different
MSE implementations.
... Has anyone thought about whether we have ther right number
of "rows" ie the right number or coverage of tests?
Matt: Mozilla is active in
changing and adding tests
... I want to post up some new Chromium tests as well
... there are likely some coverage tests
... The Mozilla new tests are being done as Pull Requests by
ms2ger and jgraham
... I will be working on fixing bad cells and adding coverage
as we go forward

MSE] Spec is ambiguous as to event behavior of an explicit MediaSource duration of +Infinity
"By my reading, the specs are currently ambiguous as to what happens when the MediaSource.duration gets set to +Infinity. Do we fire durationchange or not?"
Matt: Should we allow changing
the Duration from +infinity to something else?
... The spec only sets +Infinity when we extract it from the in
band media ie if there is no value there
... The bug contains a good question
... Does it make sense to change a finite duration to
+Infinity?
Jerry: When would this occur ie going from a fixed duration to an unknown duration?
Matt: Inifinity is used for an unbounded stream
<MattWolenetz> http://www.w3.org/TR/html5/embedded-content-0.html#durationChange
The quoted text in the bug is from Step 6 in http://www.w3.org/TR/media-source/#duration-change-algorithm
Matt: I will respond to this bug, resolve it WONTFIX since Infinity is a known value (it means unbounded). The only unknow value is NaN which is the initial value.

[MSE] Support attachment (and inspection) of MediaSource to HTMLMediaElement via HTMLMediaElement.srcObject
See suggested change in https://www.w3.org/Bugs/Public/show_bug.cgi?id=28857#c1
First the HTML5 reference is http://www.w3.org/TR/html5/embedded-content-0.html#location-of-the-media-resource
The HTML5.1 reference is http://www.w3.org/html/wg/drafts/html/master/semantics.html#location-of-the-media-resource
paulc: The question here is if we
want to align MSE 1.0 with a feature that is not in HTML5 but
is in HTML5.1
... we could fork MSE 1.0 to start working on MSE 1.1, we could
start a list of future features to include this one, etc.
... So the summary here is that adding this 5.1 feature would
definitely taking MSE out of CR and back to WD or LC
<MattWolenetz> https://www.w3.org/Bugs/Public/page.cgi?id=fields.html#bug_status
Matt will update as RESOLVED LATER and we can in the future collect together additional features for a new version of MSE
Matt: There is set of related bugs on the range removal algorithm
<MattWolenetz> bugs 27980, 27982 and one other like "no frame removed on duration truncation"
https://www.w3.org/Bugs/Public/show_bug.cgi?id=27980
https://www.w3.org/Bugs/Public/show_bug.cgi?id=27982
Matt: There two bugs are
dependent on each other
... The problem here is fall out from moving the algorithm from
synchronous to asynchronous
jerry: I will comment on the bug after the meeting.
paulc: Add the third bug to the dependency list.
proposal is that EME next week and then return to MSE in two weeks
And note Zakim is going away and we are switching to Webex for future meetings. so the phone call changes.
