Or just because it's the only one sufficiently elaborated? 21:38:12 http://www.w3.org/WAI/PF/HTML/wiki/Media_Multitrack_Change_Proposals_Summary 21:38:19 Silvia: OK, Let me summarize ... 21:38:49 Silvia: We do have a summary page. Creating it required a more in depth look at Ian's proposal. 21:39:26 Silvia: I put my concerns in a section called '"Silvia's Notes" 21:39:51 Silvia: So, I'm asking what our opinions are 21:40:31 JF: I'm noting you mention some attributes are missing, i.e. seeking. Can you say more? 21:40:53 Silvia: Yes, jumping to a specific time, either via user control or via js 21:41:30 Eric: The attribute relates to whether a seek is in progress, and don't think it's particularly helpful\ 21:41:48 Eric: We can certainly seek via the controller 21:43:11 Silvia: We have had additional discussion since Monday, including responses from Ian. There are other attribs I'm no longer looking for 21:43:44 Silvia: These are details on this proposal. 21:44:01 Silvia: If we decide to go with this proposal, we want to make sure the details are consistent with what we want. 21:44:19 Frank: Think this is a good way to proceed. I have some concerns about complexity, though. 21:44:28 JF: Any deal breaks so far? 21:44:32 Frank: With #4? 21:45:01 Sean: A few issues around exclusive, but mostly OK 21:45:23 Frank: Yes, I think it maps well to what we have. We need small bug fixes, not major rewrites. 21:45:43 Silvia: May I propose a way forward? 21:46:13 Silvia: If we're all happy--Frank, Eric, Sean, myself--can we pull our proposals and work on fixing #4? 21:46:35 Frank: Yes. My proposal was around exposing audio tracks. #4 does that. 21:46:42 Silvia: Yes, it incorporates yours. 21:47:07 Sean: I'm also prepared to withdraw mine. I believe I can achieve what I need with #4 21:47:38 Eric: I also agree. Though, I think we need to make it clear that there's more work to do to make $4 sufficient. 21:48:01 s/$/#/ 21:48:26 JF: I've not seen feedback from Opera. Anyone know how Phillip is with this? 21:48:35 zakim, mute me 21:48:35 silvia should now be muted 21:48:37 Eric: My impression is generally supportive, based on list mail. 21:49:23 JF: Other question is that we continue to indicate status on this. Can we report that we are coalescing around #4, though it needs additional work? 21:49:59 Eric: I think it makes sense for the authors of the other proposals to send email saying that. 21:50:58 Judy: I don't think it hurts to communicate additionally. 21:51:18 q+ To say that I will include in my report Thursday 21:51:49 zakim, unmute me 21:51:49 silvia should no longer be muted 21:52:37 Judy: We should also make sure to check with other key people. 21:53:28 Silvia: Think we should summarize the sticky points in an email to the list. Don't think we need to withdraw our proposals just yet. 21:54:28 http://www.w3.org/WAI/PF/HTML/wiki/Media_TextTrack_Issues 21:55:27 zakim, mute me 21:55:27 silvia should now be muted 21:56:04 judy has joined #media 21:56:08 JF: Sean, anything to discuss? 21:56:17 Sean: Most of my issues ongoing in email ... 21:56:28 Sean: It all seems to be coming together 21:56:55 Eric: I'd like us to discuss audio/video/text tracks issue 21:56:58 Sound is dropping out for me on the phone; Anybody else having this issue? 21:57:19 Eric: I probably don't have the terms off the top of my head right now ... inband, exclusive, etc 21:57:33 -Frank 21:58:00 +[Microsoft] 21:58:08 Eric: Some have proposed a single "tracks" attrib 21:58:49 Zakim, Microsoft is Frank 21:58:49 +Frank; got it 21:59:05 Sean: Understand you can have one video in the track, but doesn't prevent you from other videos, you need to use multiple video elements to get at them 21:59:28 Sean: My preference would be for a single API to find them, identify them, and switch them on and off 21:59:40 Sean: That was our TPAC approach, and I think it was simpler. 21:59:51 Sean: Currently, it's all there, but too complex 21:59:54 Eric: Agree 22:00:14 Eric: Don't think exclusive on video makes sense 22:00:33 q+ 22:00:38 Eric: Agree that's it's useful to have a single way to identify everything 22:00:49 Frank: How does this concept work? 22:01:24 Eric: Like on the element restricted to text tracks, but able to enumerate all video and audio 22:01:55 Frank: Is that a big change? 22:02:09 Eric: Yes, it would cut down from 3 to 1 the attribs on media element 22:02:59 JF: How do we move that forward? 22:03:31 Eric: We need to discuss it further in email. Either we convince everyone else--or not. But, if we agree, and it's not in the spec, then we need a change proposal on this. 22:03:54 JF: Is there a bug filed on this? 22:04:05 Eric: No, but don't think it makes sense to file a bug at this point. 22:04:19 JF: My concern is timing 22:04:54 q+ 22:05:05 q- 22:05:12 q- 22:05:41 Judy: I think you're asking about process specifically with respect to multitrack? 22:05:46 -silvia 22:06:27 Judy: I think a number of people consider this critical for last call 22:07:53 Judy: All I can say is keep refining the proposal, and let's not focus on process particularly 22:08:20 JF: So, we cut from 3 to 1, but add one other? 22:08:22 Eric: Yes 22:08:42 Eric: Though we seem to agree we can live with what's there now, though we prefer the change we're proposing 22:09:43 Sean: Understand what we have is sufficient on this to take us through the April 22 deadline. If we go further, we do it as a CP 22:09:51 Eric: Yes, it's a polishing thing 22:10:03 Judy: Now I'm confused .... 22:10:10 s/proposal/proposal, and on expedited work on this/ 22:10:42 Judy: Might we not end up with something we're unhappy with? 22:11:07 Judy: In other words, why not offer it ahead of April 22 22:12:03 Eric: It's perhaps not worth falling on our sword 22:12:25 s/something that we're unhappy with/something that would break a bit when it's cleaned up in the next LCWD/ 22:12:43 q+ 22:12:57 Eric: I think we should push on this, but we're OK either way 22:14:46 Judy: If not accepted early, wouldn't it break implementations if tried later? 22:14:50 Eric: Yes 22:15:40 Judy: So it's worthwhile to work hard on getting an optimal proposal now 22:15:50 Eric: Yes, which is why we need to take this discussion back on list 22:16:34 JF: Not on our agenda, but we have Silvia's wiki page on text format and multiple format ... 22:17:04 JF: I was expecting this is a non issue? That we would see support for multiple formats in browsers? Yes, no? 22:17:24 Eric: Are you asking if we need to define a single (or multiple) format? 22:17:51 JF: I got the impression we don't need to specify a file format in track? 22:18:16 JF: I'm unclear where the discussion is on this, this 22:18:37 Sean: The issue is whether or not track elements supports src as a sub, so you cannot put src inside it. 22:18:43 silvia has joined #media 22:18:54 Sean: So future compatibility, etc., I believe we need to allow a source selection algorithm 22:19:04 Sean: We did agree to take this up outside of Issue-152 22:19:48 JF: So should we be taking this up? Or ddo we finish 152 first? 22:20:08 Sean: We should finish 152, but I don't see anyone disagreeing on multiple formats 22:20:15 JF: So is it OK as an LC issue? 22:20:37 JF: So we can still submit a CP ... 22:20:55 Sean: I'd like to see that 22:21:07 JF: I would as well. Anyone disagree? 22:21:11 Eric: I agree with it 22:21:15 Frank: I also 22:21:18 I also 22:21:19 Bob: Also I 22:21:34 captured in http://www.w3.org/WAI/PF/HTML/wiki/Media_TextTrack_Issues for now 22:22:36 JF: Anyone willing to take this up? 22:22:47 Sean: Silvia would be the logical person. If not she, I'll do it. 22:23:18 Silvia, would you be prepared to take that wiki page and advance it to the mailing list as a CP for the spec? 22:23:27 we seem to have un animity on the proposal on this call 22:23:29 Can it wait until we've got issue-152 out the door, so after 22nd or do we want to start this before? 22:24:09 in any case, we can put a bug in the tracker 22:24:15 I think we would like to have this in the last call document, so likely before the 22nd 22:24:35 -John_Foliot 22:25:31 Judy: Is this a clarification of an existing issue or proposal? I'm concerned this not be seen as something new 22:26:00 Sean: My understanding is that this part of an old bug of ours that fell out 22:26:17 +John_Foliot 22:26:17 Sean: So it's a corollary of our actions on this 22:26:25 s/something new/something new, if it is indeed a clarificationon an existing issue or proposal/ 22:27:22 do we want to attack all the changes on the wiki page together or just the multiple formats issue on elements? 22:27:56 Judy: Mainly concerned how this is going to be presented. I'm now understanding we've worked on this before 22:28:13 just the multiple formats issue. And to state that this is part of making the spec format neutral 22:28:18 Judy: Ian almost got it into the spec? Something like that? 22:29:32 Sean: so in your eyes this is a stumbling block on accepting the Controller as a solution for issue-152? 22:29:35 JF: This was when we were discussing SRT (WebVTT); and TTML, etc 22:29:38 s/into the spec/into his proposal/ 22:29:53 JF: Our guidance was support them all 22:30:27 No this is unrelated to 152 22:31:11 Silvia, we are trying to figure out how to ensure we get this: "The proposal is therefore to implement the same mechanism for elements as we have for
