15:09:50 [paulc]

15:10:24 [paulc]
Jerry: Just started to looks at MSE results

15:13:26 [paulc]
Update from Matt:
15:14:12 [paulc]
Matt: I have been asking about the WebIDL possible problems
15:14:41 [paulc]
[Chromium] MSE w3c web-platform-tests interface.html shows multiple unexpected failures:
15:15:12 [paulc]
paulc: Matt's work has been concentrated on generates "columns" of results for different MSE implementations.
15:15:39 [paulc]
... Has anyone thought about whether we have ther right number of "rows" ie the right number or coverage of tests?
15:16:31 [paulc]
Matt: Mozilla is active in changing and adding tests
15:16:46 [paulc]
... I want to post up some new Chromium tests as well
15:17:03 [paulc]
... there are likely some coverage tests
15:18:29 [paulc]
Matt: The Mozilla new tests are being done as Pull Requests by ms2ger and jgraham
15:19:17 [paulc]
Matt: I will be working on fixing bad cells and adding coverage as we go forward

Topic: MSE Bug 28822
15:20:48 [paulc]
15:21:16 [paulc]
MSE] Spec is ambiguous as to event behavior of an explicit MediaSource duration of +Infinity
15:21:51 [paulc]
"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?"
15:22:19 [paulc]
Matt: Should we allow changing the Duration from +infinity to something else?
15:23:42 [paulc]
... The spec only sets +Infinity when we extract it from the in band media ie if there is no value there
15:23:57 [paulc]
... The bug contains a good question
15:24:23 [paulc]
... Does it make sense to change a finite duration to +Infinity?
15:24:50 [paulc]
Jerry: When would this occur ie going from a fixed duration to an unknown duration?
15:26:06 [paulc]
Matt: Inifinity is used for an bounded stream
15:26:21 [paulc]
15:28:02 [MattWolenetz]
15:30:04 [paulc]
The quoted text in the bug is from Step 6 in
15:33:34 [paulc]
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.

Topic: MSE Bug 28857
15:34:46 [paulc]
15:34:58 [paulc]
[MSE] Support attachment (and inspection) of MediaSource to HTMLMediaElement via HTMLMediaElement.srcObject
15:35:45 [paulc]
See suggested change in
15:38:26 [paulc]
First the HTML5 reference is
15:42:03 [paulc]
The HTML5.1 reference is
15:47:58 [paulc]
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
15:48:24 [paulc]
... 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.
15:51:41 [paulc]
... So the summary here is that adding this 5.1 feature would definitely taking MSE out of CR and back to WD or LC
15:53:23 [MattWolenetz]
15:54:41 [paulc]
Matt will update as RESOLVED LATER and we can in the future collect together additional features for a new version of MSE
15:55:39 [paulc]
Topic: Range removal algorithm
15:56:20 [paulc]
Matt: There is set of related bugs on the range removal algorithm
15:56:44 [MattWolenetz]
bugs 27980, 27982 and one other like "no frame removed on duration truncation"
15:57:21 [paulc]
15:57:26 [paulc]
15:58:57 [paulc]
Matt: There two bugs are dependent on each other
16:00:20 [paulc]
Matt: The problem here is fall out from moving the algorithm from synchronous to asynchronous
16:03:25 [paulc]
jerry: I will comment on the bug after the meeting.
16:04:09 [paulc]
paulc: Add the third bug to the dependency list.
16:04:15 [paulc]
Topic: Next meeting
16:04:30 [paulc]
proposal is that EME next week and then return to MSE in two weeks
16:05:11 [paulc]
