ISSUE-154
ISSUE-154?
<trackbot> ISSUE-154 -- Clarify the endsync behavior -- open
<trackbot>
[12]http://www.w3.org/AudioVideo/TT/tracker/issues/154
[12] http://www.w3.org/AudioVideo/TT/tracker/issues/154
sean: with default endsync of last, then parent will finish
immediately if no child is activated
resolved: change default for endsync to all, to go into 2nd
edition
glenn: wonders if this is a substantial change and will be an
issue or not
sean: thinks current text is broken, and this is reasonable
change
ISSUE-151
ISSUE-151?
<trackbot> ISSUE-151 -- Clarify syncbase in SMPTE continuous
mode -- open
<trackbot>
[13]http://www.w3.org/AudioVideo/TT/tracker/issues/151
[13] http://www.w3.org/AudioVideo/TT/tracker/issues/151
glenn: under 10.4, need to break out smpte/continuous to
separate bullet
andreas: wanted clarification (if needed) that in
smpte/continuous,
... a child's begin (in par context), if expressed as time
code, should it be with respect to parent or as marker
matching?
... regarding time offset expressions, don't think they are
currently admitted even for smpte/continuous mode
glenn: don't believe that was the intention, so need to double
check this
sean: agrees
mike: spec needs to make clear that smpte time base (whether
continuous/discontinuous) needs an external time base
... so may need to add note/text making it clear
... also possibly needs language making definition of epoch
clear
sean: for 2nd Ed, thinks we should retain distinction
continuous/discontinuous, but may be able to remove in 1.1 if
we agree to do so
glenn: needs to review text to verify whether time offsets are
permitted in smpte/continuous, and if not clear, then should
add clarifying text
mike: there was an issue about default value of markerMode...
... concern is that if an implementation is constrained to
support discontinuous only, then content will need to be
explicit
sean: perhaps we should mandate explicit setting of markerMode
in case timeBase is smpte
andreas: problems came from confusion of readers
mike: forces EBU to use attribute in authoring, but doesn't
really want to specify
andreas: wants smpte time base to work without having to
specify marker mode, since discontinuous seems to be common
assumption as default
sean: would be happy to accept change
glenn: if we change endsync default, then we could change this
as well
sean: plh will need to make decision
... thinks both changes (to endsync and markerMode defaults) is
correcting errors in spec
mike: perhaps we should reach out to users/authors to gauge
response
... cpc, bbc, ...
... iplayer group at bbc is using
sean: will attempt to reach out to community
mike: will give us more clear indication
ACTION sean to reach out to community to gauge response to a
possible change in default behavior for endsync and markerMode
<trackbot> Created ACTION-67 - Reach out to community to gauge
response to a possible change in default behavior for endsync
and markerMode [on Sean Hayes - due 2012-06-07].
sean: expect to make these changes (to default of endsync and
markerMode) if there are no objections
CP 001 - add animation to region, multiple elements for single set,
can reference style block, allow target for another element
[14]http://www.w3.org/wiki/TTML/changeProposal001
[14] http://www.w3.org/wiki/TTML/changeProposal001
resolved: to accept CP 001
CP 002 - Adding origin/extent to block level elements
[15]http://www.w3.org/wiki/TTML/changeProposal002
[15] http://www.w3.org/wiki/TTML/changeProposal002
sean: implementations have supported this on incorrect reading
of text
... would need to be done in 1.1
... improves locality of reference, since reduces need to
pre-declare regions
glenn: has thought about this, and believes a simple mechanism
could be defined based on anonymous regions
sean: take a look at current CP and update/add
mike: wonders about how to apply changes to anonymous region
properties, should assist with 708 mapping
glenn: should be able to animate (via set) the anonymous region
properties by referring to block element itself
sean: group should review CP 002
Review Open Actions
ACTION-62?
<trackbot> ACTION-62 -- Glenn Adams to search TT member
archives for reference to video showing smooth scrolling -- due
2012-04-19 -- OPEN
<trackbot>
[16]http://www.w3.org/AudioVideo/TT/tracker/actions/62
[16] http://www.w3.org/AudioVideo/TT/tracker/actions/62
mike: who/why was this requested?
sean: sees that plh has already found the correct reference
[17]http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.
html
[17] http://lists.w3.org/Archives/Public/public-tt/2008Dec/0155.html
mike: thinks adding an animation to do smooth scroll would not
be a good technical solution
sean: could put in note indicating that reflow should attempt
to move content in a smooth fashion
mike: could consider referring to paragraph/text in 608 that
would help define semantics
ACTION mike to provide reference to 608/708 that
defines/clarifies semantics of smooth flowing/scrolling
<trackbot> Sorry, couldn't find user - mike
ACTION sean to work with mike to provide reference to 608/708
that defines/clarifies semantics of smooth flowing/scrolling
<trackbot> Created ACTION-68 - Work with mike to provide
reference to 608/708 that defines/clarifies semantics of smooth
flowing/scrolling [on Sean Hayes - due 2012-06-07].
Adjournment
sean: adjourned
trackbot, end meeting
