16:29:39 <juberti> cullen: New changes to spec - Data API and JSEP
16:29:49 <juberti> cullen: data API is the main set of changes, going public this week
16:29:59 <juberti> cullen: JSEP changes not going into main document, going into separate document
16:30:16 <juberti> someone: Data API, is it what was discussed on list, i.e. alignment with WebSockets?
16:30:40 <juberti> someone: Does it work exactly as WebSockets, with bufferedAmount
16:30:55 <hta> draft-jesup-rtcweb-data-protocol-00.txt
16:31:06 <juberti> randell: New channels don't need to be negotiated in SDP
16:31:12 <stefanh> s/someone/adambe/
16:31:14 <dom> -> http://tools.ietf.org/html/draft-jesup-rtcweb-data-protocol-00 WebRTC Data Channel Protocol
16:31:20 <juberti> thanks stefan
16:32:02 <juberti> randell: no signaling is needed for data channel opens, but signaling needed to indicate the existence of the overall data channel
16:32:28 <juberti> hta: Michael Tuexen has a draft for SDP desriptions of data channels
16:32:51 <juberti> randell: Salvatore Loreto has a draft for SCTP over DTLS
16:33:27 <dom> so the data channel API will be incorporated in the main spec? or as a separate one?
16:33:33 <juberti> hta: there are enough drafts for the data part of the channel, and Adam has proposed a viable API for the data channel
16:33:40 <juberti> hta: is that a proper summary?
16:33:44 <dom> q+
16:33:45 <juberti> group: yes
16:33:52 <stefanh> in the main draft Dom
16:34:16 <juberti> adambe: once we get data channel to certain level of maturity, can we use the bug tracker to advance the work?
16:34:22 <jesup> http://www.ietf.org/internet-drafts/draft-ietf-rtcweb-data-channel-00.txt
16:34:35 <juberti> cullen: can't log into bug tracker, we need to fix that first
16:34:55 <jesup> cullen++
16:35:00 <juberti> cullen: we need to have a discussion about what tools we are going to use and discuss on the list, pick one way of how we are going to do things
16:35:12 <dom> ack me
16:35:34 <juberti> dom: How will the data channel API be integrated into the WebRTC spec?
16:36:06 <juberti> dom: planning to go to last call by end of 2Q 2012
16:36:20 <juberti> dom: what is timeline for moving forward with all of these documents?
16:36:41 <juberti> dom: Is the data API part of the main spec, or a separate doc?
16:36:51 <juberti> someone: part of main spec
16:37:02 <juberti> dom: will this inhibit our ability to move forward with the main spec?
16:37:32 <juberti> hta: It's part of our regular work.
16:37:44 <juberti> hta: Whether we're ready for last call, is another topic.
16:38:05 <juberti> dom: If we can do modular specs, we can have less dependencies
16:38:33 <juberti> cullen: There's not even an IETF WG document for how the signaling for data works
16:38:40 <juberti> cullen: It's a long way from done.
16:39:05 <juberti> randell: We have reasonable consensus on what should be done, but there's still a bunch of work to do.
16:39:24 <juberti> hta: Next topic
16:39:41 <juberti> adambe: We mentioned JSEP briefly (JSEP was 3.2, data was 3.3)
16:39:56 <juberti> adambe: We're not going on to 4 yet.
16:40:05 <juberti> hta: Dan Burnett isn't here
16:40:12 <juberti> dan: I am here.
16:40:33 <dom> Topic: JSEP support
16:40:36 <juberti> dan: I'm about to send a draft to the list for caps/hints
16:41:09 <juberti> cullen: Taking current IETF JSEP draft and mapping it as closely as possible into a new WebRTC API document
16:41:16 <dom> i/scribenick: juberti/Topic: Data API/
16:41:31 <juberti> cullen: I've branched the existing doc for the spec
16:41:43 <juberti> cullen: Haven't gotten it done yet, but will be out by the end of the weekend
16:42:01 <juberti> cullen: This will be a proposal that we can compare against the current draft and we can see if we think this is acceptable
16:42:23 <juberti> cullen: if so, we can move it into the main doc, which should be simple since it's a standard branch
16:42:45 <juberti> cullen: nothing surprising in this doc, since it's mainly the same thing as the IETF doc
16:43:05 <juberti> cullen: there is a second branch that adam has created; adam, please describe
16:43:48 <dom> -> https://github.com/fluffy/webrtc-w3c/tree/jsep_easy1 jspep_easy1 (adambe's) branch on webrtc editors draft
16:43:52 <juberti> adambe: I thought that the new API (JSEP) made things harder. So I took some of the things from the old API, and tried to use JSEP from this API
16:44:16 <juberti> adambe: It hasn't been communicated that we are working on 2 different branches
16:44:39 <juberti> adambe: I think this is a problem, at some point we need to figure this out
16:44:58 <juberti> adambe: There are specific operations you need to do in a specific order, and we could combine those into building blocks
16:45:16 <juberti> cullen: We need to get these drafts done and out to the lists
16:45:30 <juberti> cullen: Then we can compare and figure out what we want the editor draft to look like
16:45:40 <juberti> cullen: That's the next major set of work that we need to get done
16:45:53 <juberti> adambe: We should have entier API IDLs and have examples in place
16:46:13 <juberti> cullen: We need the baselines so that we can compare and the WG can provide feedback
16:46:23 <juberti> hta: that was a long 2 minutes
16:46:44 <juberti> hta: Does anyone else have comments on what was discussed?
16:46:53 <juberti> stefanh: I would like a time estimate
16:47:04 <juberti> cullen: by end of weekend
16:47:25 <juberti> cullen: by Sunday
16:47:37 <juberti> adambe: I can publish something tomorrow (Wednesday)
16:47:45 <juberti> adambe: Fewer changes than Cullen's
16:48:01 <juberti> adambe: Do you see a problem if I present that one first?
16:48:23 <juberti> adambe: We can't compare until Cullen's work is done
16:48:33 <juberti> cullen: THe sooner the better
16:48:40 <juberti> hta: Send it out
16:49:02 <dom> Zakim, mute me
16:49:02 <Zakim> Dom should now be muted
16:49:09 <juberti> hta: There is some skepticism, so let's see it as soon as possible

16:50:04 <dom> -> http://lists.w3.org/Archives/Public/public-media-capture/2012Mar/0033.html Constraints and Capabilities API for getUserMedia: more detailed proposal
16:50:21 <Zakim> + +44.190.881.aajj

16:50:33 <dom> -> http://lists.w3.org/Archives/Public/public-media-capture/2012Mar/0000.html  New draft-burnett-rtcweb-constraints-registry-00
16:50:52 <dom> -> https://datatracker.ietf.org/doc/draft-burnett-rtcweb-constraints-registry/ IANA Registry for RTCWeb Media Constraints
16:51:08 <Andy> Andy has joined #webrtc
16:51:25 <juberti> [dan] Registry is a very basic drat
16:51:38 <juberti> [dan] used by GetUserMedia and WebRTC
16:51:52 <juberti> [dan] constraints are for audio and video
16:52:05 <juberti> [dan] page 4, media types are audio and video
16:52:17 <dom> -> http://tools.ietf.org/html/draft-burnett-rtcweb-constraints-registry-00#section-3 RTCWeb Media Constraints
16:52:19 <juberti> [dan] currently the only constraint types are min, max, and enum
16:52:34 <juberti> [dan] contraints need to begin with an alpha character
16:52:52 <juberti> [dan] the only requirements that IANA needs to follow is a name and a reference or lst of refs
16:53:09 <juberti> [dan] Need for expert review, instructions for designated expert
16:53:16 <juberti> [dan] Names must be < 80 chars long
16:53:27 <juberti> [dan] Names should be human readable
16:53:44 <juberti> [dan] requirement that if you have a tpe of audio, must be relevant for audio streams, same for video
16:54:09 <juberti> [dan] 2 pieces for constraints - how they can be used when requesting a stream, and how they can be used as capabilites informations
16:54:13 <dom> s/[dan] /dan: /g
16:54:24 <juberti> [dan] min constraint type indicates the min value an author is willing to accept
16:55:02 <juberti> dan:could be width, height, bandwidth
16:55:50 <juberti> dan: just because you have a minwidth and a minheight, doesn't mean you can get both of those together
16:56:16 <juberti> dan: max is similar to min
16:56:36 <Zakim> + +1.425.381.aakk
16:56:41 <Zakim> -Dan_Druta
16:56:42 <juberti> dan: enum example - audio is either 'voice' or 'generic'
16:57:00 <juberti> dan: not defining this now, but this is an example
16:57:12 <juberti> dan: some other words in here - that the constraint is understandable
16:57:57 <juberti> dan: everything we've come up with so far has fallen into the 3 categories (min/max/enum)
16:59:19 <juberti> cullen: Combining height/width and aspect ratio allowed us to solve all the use cases that have been brought up
16:59:28 <juberti> dan: are there any questions about the registry?
16:59:30 <dom> Zakim, unmute me
16:59:30 <Zakim> Dom should no longer be muted
16:59:48 <juberti> dom: will we seed the registry with pre-existing constraints?
17:00:04 <juberti> dan: these documents will register constraints
17:00:09 <anant> anant has joined #webrtc
17:00:18 <juberti> dom: aspect ratio is a constraint - is that an enum?
17:00:31 <Zakim> -Dom
17:00:31 <juberti> dan: I sent a link with an example to the list
17:00:47 <fluffy> example at http://lists.w3.org/Archives/Public/public-media-capture/2012Mar/0033.html
17:00:59 <juberti> dan: we can look at that example now
17:01:09 <juberti> dan: aspect is a flaoting-point min/max
17:01:33 <juberti> dan: 4:3 can be represented (imperfectly) as floating point
17:01:51 <juberti> dan: any other questions?
17:02:10 <Zakim> +Dom
17:02:28 <juberti> dan: dom, did that answer your question?
17:02:38 <juberti> dom: will using an approximation cause problems down the line?
17:03:06 <juberti> dan: I don't think it will be a problem for most apps
17:03:23 <juberti> dan: The approximation is close enough
17:03:48 <juberti> cullen: You need to specify enough digits so that multiplying aspect times height gives you the right width.
17:04:08 <juberti> dan: work will be in precisely definining this
17:04:14 <juberti> juberti: need to find a new room
17:04:19 <Zakim> -juberti
17:04:26 <dom> scribenick: fluffy

17:05:23 <fluffy> dan: Moving off the registry topic and on to the topic of email at  http://lists.w3.org/Archives/Public/public-media-capture/2012Mar/0033.html

17:06:37 <Zakim> +juberti; got it
17:06:40 <fluffy> ???: Looking at proposal and use cases. Would be nice to have use cases for local capture and local media. 
17:06:52 <dom> s/???/richt/
17:06:55 <juberti> back
17:07:18 <fluffy> hta: There are some uses cases. HTA will try and post link. 
17:07:43 <hta> https://dvcs.w3.org/hg/dap/raw-file/tip/media-stream-capture/scenarios.html#find-the-ball-assignment--video-effects-and-upload-requirements
17:08:07 <hta> the specific requirement is "Set the webcam into a low-resolution (320x200 or as supported by the hardware) capture mode"
17:08:16 <dom> ACTION-25?
17:08:16 <trackbot> ACTION-25 -- Harald Alvestrand to action Travis to Draft a setup of initial requirements based on the WebRTC and the Scenarios document -- due 2012-03-06 -- OPEN
17:08:16 <trackbot> http://www.w3.org/2011/04/webrtc/track/actions/25
17:08:28 <fluffy> stefanh: Requirements are not spelled out in use case document - Travis is going to start requirements document that devices the requirements from the scenario documents. 
17:09:20 <fluffy> richt: Was looking at IETF requirements document but want to see how it maps to the local use cases. 
17:09:49 <fluffy> dan: will look at requirements document and make sure it aligns with this proposal 
17:10:26 <fluffy> dan: not sure of status of current link or connection but will investigate 
17:11:04 <stefanh> s/devices/derives/
17:11:07 <fluffy> dan: Constraint replaces old hint
17:11:31 <fluffy> dan: Constraint has an mandatory list and an optional list 
17:11:47 <fluffy> dan: Constraint is a key value pair 
17:12:10 <dom> Example from Dan's message:
17:12:10 <dom> Example:
17:12:10 <dom> navigator.getUserMedia(
17:12:10 <dom>   {mandatory:[video-min-height:600, video-max-bandwidth:500],
17:12:10 <dom>     optional:[
17:12:11 <dom>       video-max-aspectratio:1.333333333333,
17:12:11 <fluffy> dan: May want to come up with more restrictions on things like lengths of values 
17:12:13 <dom>       video-min-timebetweenrefframes:20,
17:12:15 <dom>       video-min-framerate:30,
17:12:17 <dom>       video-autowhitebalance:on]},
17:12:19 <dom>   gotStream, didntGetStream);
17:13:24 <fluffy> dan: There was a questions for algorithm to process these constraints. This time there is a write up of the algorithm.
17:14:03 <fluffy> dan: look at the example, after the algorithm, this shows what it might look like 
17:14:15 <dom> how would you specify whether you want audio (or not) at all? is "audio" a constraint itself?
17:14:16 <DanD> Zakim, aakk is Dan_Druta
17:14:16 <Zakim> +Dan_Druta; got it
17:14:19 <fluffy> dan: two lists, and the lists are ordered 
17:15:16 <dom> (I'm not sure I understand how I would do echo cancellation with that approach)
17:15:56 <fluffy> dan: In this case, the intent is they get a video stream with a min hight of 600 pixels, and max bandwidth of 500 (whatever the units are) . These are absolute and if they don't get this they want an error if both of these are not satisfied. Additional, they have some optional things they hope can satisfied in priority order. They would like aspect ration of 4/3. 
17:16:03 <dom> Zakim, mute me
17:16:03 <Zakim> Dom should now be muted
17:16:15 <fluffy> dan:  video-autowhitebalance:on should be video-enum-autowhitebalance:on
17:16:57 <fluffy> dan: If browser can do       video-min-timebetweenrefframes:20, and als could do       video-min-framerate:30, but not both, then the browser should do the       video-min-timebetweenrefframes:20,
17:18:19 <fluffy> dan: When talking about mandatory constraints, order does not matter. For optional, needed to sperate audio and video
17:18:52 <fluffy> dan: Basis is a set and algorithm is removing some streams from it 
17:19:04 <fluffy> dan: want to make sure never remove all audio or all video stream 
17:19:43 <fluffy> dan: could end up with all stream remvoed 
17:19:50 <juberti> Dropping off
17:19:54 <Zakim> -juberti
17:22:31 <fluffy> dan: In the cases of optional for two different type of media constraint, does optional mean eliminate all of one type, is that OK, or is there implicit assumption they want at lease one video and one audio. As an app developer, I would want one of both 
17:23:30 <fluffy> dan: Moving to Capabilities 
17:24:03 <fluffy> dan: having challenges with webild 
17:24:28 <fluffy> dan: In the trusted cases, for each device, we get the constraints with values. 
17:24:30 <Zakim> - +44.190.881.aajj
17:24:31 <dom> I think that rather than {camera001:...,camera002:...} it would be more logical to have {cameras:[{...}, {...}]}
17:25:19 <fluffy> dan:  So when we get video-max-width:  1024, this means there is no video stream this camera can provide with a width greater than 1023 
17:26:01 <fluffy> dan: did not deal with ENUM values yet - not sure that this is information we need. Will add if this is needed
17:26:01 <dom> I think enums would be logically mapped to array of values?
17:26:35 <Zakim> + +1.289.261.aamm
17:26:42 <Josh_Soref> Zakim, aamm i me
17:26:42 <Zakim> I don't understand 'aamm i me', Josh_Soref
17:26:47 <Josh_Soref> Zakim, aamm is me
17:26:47 <Zakim> +Josh_Soref; got it
17:26:50 <fluffy> hta: Can imagine a case where one is using values and would want to know all values. For example camera supports b/w , color, and infrared
