16:16:03 <mav> I've tried to map the most useful DASH role combinations to the defined HTML
16:16:03 <mav> values. Hopefully that's good enough for most purposes. If there are specific
16:16:03 <mav> use cases that this doesn't handle, please file separate bugs (I don't mind if
16:16:04 <mav> they are handled as LC1 bugs).
16:16:06 <mav> If there are other specifications that define specific roles that should be
16:16:08 <mav> mapped here, please file separate bugs with links to the relevant specs (I
16:16:10 <mav> don't mind if they are handled as LC1 bugs either).

16:17:40 <duncanr> ... if there are relevant bugs regarding to other external specs then they will be considered as LC1

16:23:42 <kaz> s/... has/Clarke: has/
16:24:11 <duncanr> ... one of the issues from last week was what html would look like for video element that uses script to parse manifest
16:25:03 <duncanr> ... looking at chromium it looks like regular video element with some js that gets media chunks and adds a few listeners
16:25:46 <duncanr> ... do we want the video element to specify this?
16:26:39 <duncanr> Jason: generally agrees
16:26:49 <duncanr> Clarke: will write something on wiki
16:28:02 <duncanr> Clarke explains APIs
16:28:28 <duncanr> Clarke: anody have any thought on pros and cons?
16:28:38 <kaz> s/anody/anybody/
16:28:44 <duncanr> Kilroy: there's some issues around the simple append.
16:28:52 <duncanr> ... assumes you are just appending one segment
16:29:03 <duncanr> ... there may be sperate appending for different media types
16:29:49 <duncanr> ... issue of time alignment too
16:30:11 <duncanr> ... in best case they are nicely aligned, other times they could overlap
16:30:18 <duncanr> ... the script needs to know that
16:30:45 <duncanr> ... segment decoded needs to be able to calculate common time bases
16:31:30 <duncanr> ... complexity of accurate splicing 
16:32:04 <ph> zakim, who is making noise?
16:32:15 <Zakim> ph, listening for 11 seconds I could not identify any sounds
16:32:47 <duncanr> scibed missed question
16:32:51 <kaz> jason: @@@
16:33:06 <kaz> s/scibed/scribe/
16:33:52 <duncanr> Clarke: sounds like there are some things that need to be fleshed out
16:34:24 <duncanr> Kilroy: the whatwg and chrome proposals both have same fundamental issues
16:35:41 <duncanr> ... the DASH spec has flags that describes media.

16:38:02 <duncanr> scribe couldn't hear question
16:39:11 <duncanr> Kilroy: two profiles for MPEG-TS
16:40:10 <duncanr> ... it is necissary to know capability of decoder
16:40:34 <duncanr> ... can in handle everything in manifest file?
16:41:02 <duncanr> ... mpeg2-ts are self-initialising
16:41:09 <duncanr> ... headers are repeated
16:41:38 <duncanr> ... iso files and others have header information that is required to start decoding
16:41:52 <duncanr> ... you might have to start by appending an initialise segment
16:42:20 <duncanr> ... for live encoding you might have to initialise for each segment
16:42:59 <duncanr> ... but on the other hand these headers might be inband and won't need intialising
16:43:37 <duncanr> ... does that script retain the intialisation or does the player do this?
16:43:53 <duncanr> Clarke: the MIME time is not sufficient to know about this
16:44:01 <kaz> s/time/type/
16:45:38 <duncanr> Kilroy: no it only tells you about a container, codec but not on detailed profile
16:46:06 <duncanr> ... impossible to characterise all paramters. 
16:46:55 <duncanr> Clarke: limit those MIME types to most popular collections?
16:47:20 <duncanr> Kilroy: MIME type list would be huge to specify everything 
16:48:09 <duncanr> ... do you allow switching between HD and SD? how is adaptive coding and scaling done?
