the WD documents</p>
|

<p class='irc'><<cite>silvia</cite>> they can be mailed

<p class='irc'><<cite>raphael</cite>> you mean a change

log section ?</p>
|

<p class='irc'><<cite>silvia</cite>> no, just every "cvs

diff</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> and it is sent out

to the group of people working on the code/document</p>

|
|
|
|
<p class='irc'><<cite>raphael</cite>> i'm not sure this

is really useful, particularly since some people do just one

every characters they change :-)</p>

<p class='irc'><<cite>silvia</cite>> I would already use

|
|
|

<p class='irc'><<cite>raphael</cite>> Are these 2 add-ons

required: <a href=

for inspecting headers request and response?</p>

<p class='phone'><cite>scribe:</cite> difficult to use

|
|
|
|
<p class='irc'><<cite>conrad</cite>> davy: do you have an

"http://schutz.elis.ugent.be:8080/DownloadServlet/fragf2f.ogg">http://schutz.elis.ugent.be:8080/DownloadServlet/fragf2f.ogg</a>
|
|
is 404</p>
|
|
|
|
<p class='phone'>davy ... these are indeed the add-ons</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> raphael: they are
|
|
not required, but they help you work out what is going on</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> you can also create
|
|
the http headers through javascript</p>
|
|
|
|
<p class='irc'><<cite>conrad</cite>> the problem is that
|
|
UAs do not understand time Content-Ranges</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> I want to work on
|
|
this as a demo with davy's server</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> yeah, everything has
|
|
to be emulated with javascript right now</p>
|
|
|
|
<p class='irc'><<cite>conrad</cite>> so we need to
|
|
suggest that UAs display the "start-end/total" values
|
|
appropriately, eg. in the seek bar</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Davy points out
|
|
that the instance-length in the content-range headers is
|
|
ignored by the media player plugin</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> Conrad: is it
|
|
something we need to push to the browser vendors ?</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> some of it</p>
|
|
|
|
<p class='phone'>davy ... server implementation is allright, we
|
|
just need players that support these extra headers</p>
|
|
|
|
<p class='irc'><<cite>conrad</cite>> firefox 3.5 will use
|
|
X-Content-Duration to display the seek bar</p>
|
|
|
|
<p class='irc'><<cite>conrad</cite>> value is a floating
|
|
point number of seconds</p>
|
|
|
|
<p class='irc'><<cite>raphael</cite>> it is to fake it
|
|
and will work only on firefox ? but worth to test it</p>
|
|
|
|
<p class='irc'><<cite>conrad</cite>> sure</p>
|
|
|
|
<p class='phone'>within IBBT we will also try to come with a
|
|
media player that is able to understand all headers</p>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> the point is that
|
|
browser vendors need to see the impact and understand the
|
|
usefulness, which is why a javascript implementation is
|
|
useful</p>
|
|
|
|
<h3 id="item06">AOB</h3>
|
|
|
|
<p class='irc'><<cite>silvia</cite>> then they can decide
|
|
to follow our specifications and implement it natively</p>
|
|
|
|
<p class='irc'><<cite>conrad</cite>> davy: also try
|
|
putting the urls through validator.annodex.org , just thinking
|
|
we can update that for such testing</p>
