Hi Bryan and Download TF, It seems there is some discussion on recording API (using speech) by the Speech API CG, and I'm wondering if somebody from the Download TF is interested in this. Thanks, Kazuyuki -------- Original Message -------- Subject: Re: Call for Consensus to publish a First Public Working Draft of "MediaStream Recording API", deadline 31 Jan 2013 [resend adding DAP] Resent-Date: Thu, 24 Jan 2013 16:15:11 +0000 Resent-From: public-web-and-tv@w3.org Date: Thu, 24 Jan 2013 09:14:17 -0700 From: Glenn Adams <glenn@skynav.com> To: Jim Barnett <Jim.Barnett@genesyslab.com> CC: Frederick.Hirsch@nokia.com <Frederick.Hirsch@nokia.com>, public-device-apis@w3.org <public-device-apis@w3.org>, public-webrtc@w3.org <public-webrtc@w3.org>, W3C Web and TV <public-web-and-tv@w3.org>, Ed Shrum <ed.shrum@cox.com> Thanks for your response. My primary concern for my first comment is that this specification should be able to support DVR/PVR functions. Although it doesn't seem specifically designed for this purpose, it appears to provide significant support in that direction. I would also note that the Web & TV IG has initiated a Recording and Downloading Media task force [1] which I expect will produce a requirements document. IMO, it would be detrimental if DAP produces a Media recording API that does not satisfy the requirements coming from this activity.

The API is defined to work with any object of type MediaStream, whether local or remote. If there is some other object that needs to be recorded, I would think that the question would be how to convert it into a MediaStream. The getUserMedia spec would be the right place to do that, or possibly a separate spec, but the process should be transparent to the MediaRecorder class. (There’s a separate discussion going on about whether we want to taint certain MediaStreams to prevent recording for security reasons, but that’s orthogonal to this issue, I think.)____ __ __ On the issue of where takePhoto() goes, it was originally a method on VideoTrack. We moved it to the recorder class because it seemed to have a lot in common with recording. I don’t particularly care where it goes, though I wonder if a new interface is justified, given how limited the functionality is. I’ll go with whatever the majority decides.____ __ __ __-__Jim____ __ __ *From:*Glenn Adams [mailto:glenn@skynav.com <mailto:glenn@skynav.com>] *Sent:* Thursday, January 24, 2013 9:21 AM *To:* Frederick.Hirsch@nokia.com <mailto:Frederick.Hirsch@nokia.com> *Cc:* public-device-apis@w3.org <mailto:public-device-apis@w3.org>; public-webrtc@w3.org <mailto:public-webrtc@w3.org> *Subject:* Re: Call for Consensus to publish a First Public Working Draft of "MediaStream Recording API", deadline 31 Jan 2013 [resend adding DAP]____ __ __ >From my brief read of this draft, I have the following comments:____ * Document should describe how it the mechanisms defined can be used to record media streams deriving from non-local devices, specifically, how to record media streams obtained from external servers, e.g., streams fetched and presented by HTMLMediaElement.____ * The members takePhoto() and onphoto should be moved to a separate interface to make the MediaRecorder interface more generic, and not tied to specific types of media sources.____ Regards,____ Glenn____ __ __ On Thu, Jan 24, 2013 at 6:31 AM, <Frederick.Hirsch@nokia.com <mailto:Frederick.Hirsch@nokia.com>> wrote:____ DAP members: The Media Capture Task Force [a] is a joint Task Force of the DAP and WebRTC working groups.
