paulc: since this if first couple of meetings, I left this info, will be dropped next week
15:20:27 [Clarke]
paulc: Aaron to start collecting bugs
15:20:40 [Clarke]
Acolwell: started three threads for discussions
15:21:09 [Clarke]
paulc: Three topics, 10-12 minutes on each
15:21:20 [Clarke]
paulc: Aaron want to start onfirst topic?
15:21:23 [Clarke]
Topic: Moving mediasource methods into separate objects
15:21:48 [Clarke]
acolwell: majority of people seem to support this
15:21:58 [Clarke]
...fewer comments than expected

15:22:00 [Clarke]
paulc: Is there a concrete description in message 71?
15:22:05 [Clarke]
acolwell: yes
15:22:19 [Clarke]
paulc: please step us through concrete items
15:22:29 [BobLund]
q+
15:22:44 [Clarke]
acolwell: introduced 3 objects,
15:22:51 [Clarke]
...mediasource object
15:22:52 [Clarke]
...you would use this object for appending
15:23:25 [Clarke]
...sourcebuffer objects map to source buffer in specification, append, abort, stream
15:23:43 [Clarke]
...mediasource object is responsible for managing lists of active source buffers and add source buffers during playback and announce readystate
15:23:57 [Clarke]
...now split into media objects
15:25:09 [yang]
does media source still has the same problem of encrypted media on event firing at media element commented by mc last time?
15:25:14 [Clarke]
paulc: maybe aaron type some of this

15:25:50 [Zakim]
[Microsoft] has paulc
15:26:37 [acolwell]
MediaSource is attached to the HTMLMediaElement by using URL.createObjectURL() to create a blob URL. The blob URL is then assigned to the src attribute on the HTMLMediaElement
15:27:03 [acolwell]
Three object are being proposed Media, SourceBufferList, SourceBuffer
15:27:14 [paulc]
ack bob
15:27:38 [Clarke]
BobLund: recent email discussion about how new object linked to media element has that been resolved?
15:27:45 [Clarke]
acolwell: did not see that
15:28:11 [Clarke]
BobLund: How would you find media element linked to corresponding object
15:28:27 [Clarke]
acolwell: about the source not the element attached
15:28:30 [adrianba]
q+
15:28:41 [Clarke]
...i guess we could provider reference linking to media element
15:29:16 [Clarke]
...there was outstanding question. could specify media element since media object is new.
15:29:26 [Clarke]
...if multiple elements there may need to be a list

RRSAgent, make logs public
15:30:06 [Clarke]
adrian: 2 points: I agree with aaron that there should be a restricting linking media source to single media element. don't think we need more
15:31:17 [Clarke]
...the idea of need to time events to new object and back to media element, I don't think that is necessary. JS app can remember association. Events fired against that should have sufficient info available.
15:31:26 [Clarke]
acolwell: I agree. JS can keep track of this.
15:31:31 [Clarke]
paulc: any other questions?
15:31:55 [yang]
So can we modify the media element status in media source object to trigger media element fire a event we want?
15:32:00 [Clarke]
acolwell: OK for me to update spec text?
15:32:31 [Clarke]
paulc: question- I believe this is similar to 1st item for encrypted media proposal. Are we doing due diligence?

RRSAgent, make logs public
15:32:53 [Clarke]
...maybe due to 1st meeting, but need to be clear whether we can make decision independent of two specs
15:33:06 [Clarke]
acolwell: goal is similar but objects are independent
15:33:07 [MikeSmith]
RRSAgent, make minutes

15:33:32 [Clarke]
...may have consensus that object oriented approach is better
15:34:12 [Clarke]
adrian: even if not new object the media source proposal is cleaner that CP spec. Decision can be made independently
15:34:29 [Clarke]
paulc: any objection to moving media source methods into separate objects as defined in message 71?
15:34:51 [yang]
I am ok.
15:35:11 [Clarke]
Resolution: Aaron to make change and inform people that it is done.
15:35:14 [Clarke]
paulc: Does that sound like a plan?
15:35:38 [Clarke]
acolwell: Need to update links as well
15:35:51 [Clarke]
RESOLUTION: Aaron to make change and inform people that it is done.
15:35:52 [markw]

15:36:31 [Clarke]
paulc: reference the bug as well and make the link from the bug (2-ways)

15:37:14 [Clarke]
markw: should we publish as editors draft?
15:37:14 [Clarke]
paulc: ok by me. Mike?
15:37:25 [Clarke]
Mike: no process or policy
15:38:23 [Clarke]
...all documentation on policy is for working drafts. Precedent is editors to mark as editors drafts before accepted
15:38:24 [Clarke]
...maybe say document not yet accepted as deliverable by WG
15:38:56 [Clarke]
...does not have to be marked as unofficial. Just note status with WG
15:39:03 [Clarke]
paulc: send to editors to have them resolve this

adrian: should we replace the current method or make as additional mechanism
15:42:49 [Clarke]
...perhaps have a file using file reader API, with URL would need blob and read with their switch - less efficient

15:44:43 [Clarke]
acolwell: orignal idea was to use blobs using blob builder
15:45:02 [Clarke]
...or from file. Filereader could give you blob
15:45:06 [yang]
I think we may have an aditional method, during the drafting we may finally know whether we need "uint8array" parameter.
15:45:40 [acolwell]
The append URL proposal attempts to improve the UA's ability to use the cache and to be able to rate limit appending.
15:46:01 [acolwell]
It is possible that these two goals don't need to be solved with the same mechanism

15:46:38 [acolwell]
If we allow the existing append mechanism to stay in the spec, then we need to figure out a new way to rate limit these appends

adrian: agree with adding new methods getstats from url. if downloading data having ua doing that by using range is most efficient : OK with change
15:48:57 [Clarke]
...if data already in JS, with no URL to read from, then creating a blob url over data in JS means round-trip through network
15:49:18 [yang]
so rate limit solution only work for url alternative, no solution for existing mechanism to rate control? But I am ok for replacing old with url way....
15:49:35 [Clarke]
...need to create blob, then URL then pass asynchronously through net stack and back - lots of unnecessary processing over passing directly
15:49:47 [Clarke]
paulc: aaron understand?
15:49:57 [Clarke]
acolwell: yes, see how that could be problematic
15:51:05 [Clarke]
adrian: however, yang made point: maybe keep original method, but mark in spec - still need to consider whether we really need it.
15:51:09 [Clarke]
acolwell: keep original? answer now seems to be yes
15:51:46 [Clarke]
paulc: WG will need to decide how to answer questions like that. Could file bug against old signature.
15:52:13 [Clarke]
acolwell: OK. another question: what is convention? different names? overload?
15:52:38 [Clarke]
adrian: can overload if method can be distinguished
15:52:39 [Clarke]
paulc: just different number of parameters?
15:52:57 [Clarke]
adrian: kind of. JS doesn't support overloading in this way
15:53:43 [Clarke]
... effectually, writing code into implicit method - figure out which sub method was intended
15:53:43 [Clarke]
...look at data passed in and figure it out

Topic: Time-stamp offset mechanism
15:55:05 [Clarke]
acolwell: purpose is to allow appending media into a presentation that may have been created on a different timeline
15:55:05 [Clarke]
...ad insertion is one example - not only application
15:55:34 [Clarke]
...both pieces of content may start with time stamp 0
15:55:48 [Clarke]
...next insertion apply offset to media to insert with correct time
15:56:04 [Clarke]
...append will overwrite part of existing stream
15:56:16 [jasonlewis]
q+
15:56:30 [Clarke]
...ex: 30 seconds added to time stamp
15:56:48 [paulc]
ack jason
15:56:50 [markw]
q+
15:56:52 [Clarke]
...can adjust offset again in other segment. Splice in content on a different time line
15:56:56 [adrianba]
q+
15:57:16 [Clarke]
jason: Does that media being appended have internal time stamp?
15:57:17 [Clarke]
...can use absolute rather than offset
15:57:34 [yang]
I have question, if previous append fail, new append can start from the success part of previous faild append? I thought if faild, new append will overwrite the whole part but not start from ....
15:57:36 [Clarke]
acolwell: spec now requires time stamp to manage buffer
15:57:49 [BobLund]
q+
15:58:15 [duncanr]
q+
15:58:21 [Clarke]
...having knowledge of where actual time stamps are is issue. Say next segment will start at this time so don't need to know internal time.
15:58:35 [paulc]
speakers - please be ready to type in your question
15:58:40 [Clarke]
...you then have to create mechanism for clearing offset - so don't have to disable
15:58:50 [Clarke]
...may need to talk more about mechanism

adrian: might need a way to clear this. might consider having stack - pop offset off of stack. Don't need to remember where I am in time
16:00:29 [Clarke]
Bob: have you considered how this would work with random access?
16:00:40 [Zakim]
-Mark_Vickers

duncan: do we really need to define mechanism for this or should we handle in JS?
16:01:58 [Clarke]
acolwell: could do in application, but no guarantee of seamless
16:02:07 [Zakim]
-pladd
16:02:18 [Clarke]
...JS not necessarily timely - no guarantee
16:02:22 [Martin]
isn't absolute time and reset to presentation time enough, is there a use case for multiple splices where the application doesn't need to track timing?
16:02:45 [BobLund]
We have implemented media insertion at the application level using an iFrame that overlays the media frame.
16:02:49 [paulc]
ack martin
16:02:55 [Clarke]

paulc: continue discussion on email
16:03:09 [Zakim]
-BobLund
16:03:30 [Clarke]
martin: seems absolute time, then reset should be enough. App needs to know where appending is taking place
