15:20:34 [Zakim]
+Canon
15:20:39 [JanL]
bug 12399
15:20:53 [JanL]
In process. Should this be generalized beyond video? Maybe start with video and consider a broader scope in any solution.
15:21:47 [JanL]
bug 13359
15:22:01 [JanL]
In process. Discussions on parameters and whether changes are necessary. "Must be human readable" requirement.
15:22:22 [JanL]

15:22:28 [JanL]
2 new bugs
15:23:01 [JanL]

15:24:19 [JanL]
bug relates not being able to piping multiple streams
15:24:21 [joesteele]
+q
15:24:36 [JanL]
nothing is stated as to how resources are freed
15:25:03 [joesteele]
q-
15:25:06 [JanL]
what webkit does the resource are not released when video tag is unloaded
15:25:23 [JanL]
only when garbage collection actually removes the resources
15:26:03 [JanL]
joe points that decryption resources are not released
15:26:26 [JanL]
david: video decoder has been the main issue
15:27:02 [JanL]
aeren: what is issue, if opening multiple videos
15:27:23 [Zakim]
- +1.425.269.aabb
15:27:37 [JanL]
some content depending on decryption may require hardware
15:27:57 [JanL]
which is locked
15:28:37 [JanL]
there are 2 errors, if there are policy concerns and there should be a warning if software is going to be used as fallback
15:29:41 [JanL]
many audio tracks may be opened at the same time in order to give special effects which may confuse what should be handled
15:30:21 [KevinStreeter_]
KevinStreeter_ has joined #webtv
15:30:28 [JanL]
david: when listening audio may be persisted
15:30:46 [JanL]
when should resources be released
15:31:00 [JanL]
javascript may remove tag from dom and reinsert it
15:31:21 [JanL]
same media element may be used when transferring it
15:31:39 [JanL]
david: may some use cases are required
15:32:19 [JanL]
gius: add the use cases into the bug
15:32:24 [JanL]
next bug
15:32:35 [JanL]
https://www.w3.org/Bugs/Public/show_bug.cgi?id=16480
15:33:06 [JanL]
when needing to have broadcast channel where there is a mosaic of the channels
15:33:25 [JanL]
may want an interface to select one of the channels
15:34:50 [JanL]
need to draw borders in order to select channel or everything is done in javascript
15:35:24 [JanL]
map element would be a much easier solution to be used but it is not available for the video element
15:35:29 [JanL]
only images
15:37:43 [bryan]
is there anyway to use SVG as an scalable overlay frame, and trigger events from it?
15:37:50 [JanL]
for each of the elements need to put the source to handle the multiple stream types
15:37:59 [bryan]
just a random idea
15:38:00 [JanL]
wiht map you can associated anchors
15:39:13 [Clarke]
q?
15:39:14 [JanL]
gius: investigate if there are better solutions
15:41:06 [JanL]
bryan: there might be markup language like svg that can help in providing a solution
15:41:33 [JanL]
giuseppe to explain how bugzilla to be used
15:41:49 [JanL]
bugzilla to be used to collect issues
15:42:08 [JanL]
and it is a better way to monitor questions and share with other groups
15:42:27 [JanL]
it is a prefilter of the raised issues
15:42:49 [JanL]
if agreed then it is pushed into the different WG's
15:42:58 [JanL]
there is a template for filling out issues
15:43:05 [JanL]
it is in the main wiki webpage
15:43:12 [giuseppe]
http://www.w3.org/2011/webtv/wiki/Main_Page#Template_for_Use_Cases
15:43:34 [JanL]
use template to describe use case
15:44:17 [JanL]
clarke: what could be useful to add the template to the mptf as a reference
15:44:48 [JanL]
... once the discussion is started it is necessary to highlight to clarke to be discussed
15:45:13 [JanL]
... person who filed bug has responsibility to highlight it
15:45:41 [JanL]
... general discussion
15:46:01 [JanL]
...in next couple of week finishup the requirements documents
15:46:20 [JanL]
...use time every week to discuss opened bugs
15:46:33 [JanL]
... soon to limit the number of phone conferences
15:47:01 [JanL]
... if any suggestions forward them to clarke as to how to progress
15:47:17 [JanL]
move to phone conf every 2 weeks
15:47:42 [JanL]
adhock would make it harder to plan attending
15:48:11 [bryan]
I like the building of the agenda on the wiki. It's easy to keep up as the topics for discussion are collected.
15:48:22 [JanL]
clarke: plan to continue phn conf every week until req done
15:48:36 [kaz]
s/phn/phone/
15:48:48 [JanL]
joe to be scribe next week
15:48:50 [bryan]
That approach can help make the calls more adhoc but keep people engaged on the agenda as it builds.
15:49:38 [JanL]
could use wiki agenda to identify critical mass of issues to be discussed
