    <p class='irc'>&lt;<cite>foolip</cite>&gt; Will the France

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Sorry, I can't hear
    at all, will try the US bridge instead</p>

    <p class='phone'><cite>raphael:</cite> hours in NPT time codes
    will be optional</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; ACTIOn-192?</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ACTION-192 -- Davy
    Van Deursen to update the specification to state what the
    processing should do when media fragments request (time
    dimension) does not match exactly how the media item has been
    encoded -- due 2010-11-08 -- OPEN</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; <a href=

    http://www.w3.org/2008/WebVideo/Fragments/tracker/actions/192</a></p>

    <p class='phone'><cite>raphael:</cite> SMPTE time codes that do
    not match the encoding settings of the media resource result in
    an error case<br />
    ... perhaps 416 is too strong for this case, should we change
    this?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Zakim: mute me</p>

    <p class='phone'><cite>Yves:</cite> send a 200 instead</p>

    <p class='phone'><strong class='resolution'>RESOLUTION: when
    the server sees a mismatch in requested SMPTE time code and the
    encoding settings of the media resource, it will return the
    whole resource (200)</strong></p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; =&gt; code updated
    (JavaCC grammar) with optional hours</p>

    <p class='phone'><cite>raphael:</cite> comment from Philip:
    which pixels should we use (physical pixels or display
    pixels)<br />
    ... we decided to use display pixels</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; CSS is not relevant
    :)</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; This is not a CSS
    issue.</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; see <a href=
    "http://dev.w3.org/csswg/css3-values/">http://dev.w3.org/csswg/css3-values/</a></p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; <a href=
    "http://dev.w3.org/csswg/css3-values/#the-px-unit">http://dev.w3.org/csswg/css3-values/#the-px-unit</a></p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; Yes Philip, but it
    is confusing to reuse a term to mean something else that
    something which has an accepted definition</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; ... so we are right
    to define what we mean without talking to CSS pixels</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; ... like you said,
    this has nothing to do with CSS</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Didn't we already do
    that yesterday?</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; yes, I'm
    summarizing the discussion</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; 2nd paragraph of
    <a href=

    http://www.w3.org/2008/WebVideo/Fragments/WD-media-fragments-spec/#naming-space</a></p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; No, only the media
    resource itself has an influence</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; I agree</p>

    <p class='irc'>&lt;<cite>dsinger</cite>&gt; css pixel latest
    definitions here &lt;<a href=

    <p class='phone'><cite>raphael:</cite> other discussion: should
    we specify how media fragments are rendered in a browser?<br />
    ... we created a section 7.1</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; raphael: can you
    paste links to the mails/bugs you've sent?</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; foolip: see above</p>

    <p class='phone'><cite>Yves:</cite> MIME type definition never
    includes rendering specifications</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; I disagree, I think
    it's our problem.</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; Dave: presentation
    should be consistent in all context</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; One might say that
    the problem is that we have ambiguous syntax, both for t= and
    xywh=</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; I'm not sure I see
    the ambiguity you're talking about</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; the semantic is
    unambiguous, displaying it is undefined.</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; Jack: I would like
    that implementers propose both choices (show focus and
    crop)</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; (undefined, so
    ambiguous :) )</p>

    <p class='phone'><cite>Dave:</cite> so that the choice is up to
    the author</p>

    <p class='irc'>&lt;<cite>pchampin</cite>&gt; +1</p>

    <p class='phone'><cite>Jack:</cite> if the author decides about
    the rendering, the rendering should be specified in the URI</p>

    <p class='phone'><cite>Yves:</cite> distinction between # and ?
    is not an option for rendering indications</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; I observe that the
    room is more and more inclined to add a "crop" keyword</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; I would caution
    against that, unless you have an implementor willing to
    implement both xywh and crop.</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; Philip, will you
    only implement the crop aspect?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; I know that
    implementing highlight seems not very useful, but I'm not
    saying that we *will* implement any other behavior.</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; That's the extent
    (lack of) commitment :)</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; OK, so your
    priority 1 will be crop (sprite) ... and of you have resources,
    highlight, right?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; No, I don't think
    there's a reason to ever implement highlighting, and that
    maaaaybe, given resources, crop could be worthwhile</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; I observe that the
    group is willing to take an important decision, changing the
    semantics of rendering spatial media fragments and defaulting
    to crop</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; Philip will
    definitively implement "show focus" in context for the temporal
    dimension, and possibly only "crop" for the spatial
    dimension</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Uh, I never said
    definite about anything.</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; ok Philip :-) I
    just over interpret what you have said, feel free to
    correct</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; For #t=10,20 the
    most useful behavior to implement is focusing, and we *might*
    implement that, as you saw at FOMS</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; For
    #xywh=10,10,20,20 the most useful behavior is cropping, but I'm
    not sure we'd implement even that.</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; It depends on what
    other browser vendors think, really.</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; thanks for the
    clarification</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; #xywh with cropping
    is actually more useful to images than to video</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; e.g. handing over
    spliced images to a JS API</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; interesting
    question: what if somebody wants to highlight an area in a
    cropped frame?</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; you can define a
    highlight window to be the cropped part</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt;
    #crop=40,40,20,20&amp;xywh=10,10,20,20 would work - but not if
    we only allowed one</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; Yves, how?</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; img src=foo z-index 0,
    effect-blur + img src=foo#xywh=.... z-index 1, positionning
    x,y</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; and you got the
    higlight</p>

    <p class='phone'><cite>Jack:</cite> i would like that there is
    a CSS styling attribute that indicates if its in or out of
    focus</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; yeah, but that's not
    handed on through a URL</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; we don't need any
    spatial media fragments to do any of this in CSS</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; oups, no I don't
    understand what you mean?</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; you can do both,
    cropping and highlighting in HTML with a &lt;video&gt; or
    &lt;audio&gt; element and CSS, you don't need to provide those
    coordinates in a URL</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; raphael: thanks</p>

    <p class='phone'><cite>silvia:</cite> if we rely on CSS to
    specify the rendering of spatial fragments, we should rely on
    CSS for the rendering of all media fragment axes</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; if I read silvia,
    higlighting is CSS driven, cropping is #xywh=</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; What was the last
    sentence?</p>

    <p class='phone'>video { temp_frag: highlight; spat_frag: crop
    )</p>

    <p class='phone'>an example of a CSS statement?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Let them use image
    maps :)</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; from a browser POV
    we have to make clear statements what happens in a compatible
    manner across browsers when the URL ends up in the @src
    attribute of &lt;video&gt; or &lt;img&gt;, and what happens in
    the URL bar</p>

    <p class='irc'>&lt;<cite>dsinger</cite>&gt; how about "the
    normal user-agent behavior is to crop to the indicated spacial
    and/or temporal region; however note that users and user-agents
    can easily remove the fragment identifier and view the
    remainder, and so authors should not rely on the cropping, and
    user agents may employ other behavior (such as offering users
    the choice between crop and focus)"</p>

    <p class='irc'>&lt;<cite>dsinger</cite>&gt; ?</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; Room agrees thay by
    default, the behavior should be crop</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Why should we expect
    them to be consistent, when they're completely different
    dimensions?</p>

    <p class='irc'>&lt;<cite>jackjansen</cite>&gt; Because that is
    called "elegance"</p>

    <p class='phone'><cite>Raphael:</cite> I argue that

    Range Request</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; if typed in the
    browser bar, the only way of doing a range request safely would
    be to use a unit that is compatible with what we expect, so
    seconds</p>

    <p class='phone'><cite>Silvia:</cite> we cannot really enforce
    anything</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Incidentally, #t=30
    on text/html resources is the most useful, but unfortunately
    not something we can standardize or implement</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; (as it default to
    return the whole thing back). Sending byte range requests will
    add latency and be generally bad in taht case</p>

    <p class='phone'><cite>Silvia:</cite> but I will recommend

    <p class='irc'>&lt;<cite>Yves</cite>&gt; if we trigger a

    html5 then ;)</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Yes, but I doubt we
    can overload fragment identifiers for HTML without breaking the
    web</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt;
    example.com/video.ogv?v=1&amp;t=310s</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; foolip, that was not
    raphael's point, his point was, what should the browser do
    before knowing it's html or video</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt;
    example.com/video.html?v=1&amp;t=310s</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; without the context of

    <p class='irc'>&lt;<cite>silvia</cite>&gt; that would signify

    <p class='irc'>&lt;<cite>silvia</cite>&gt; ok, we are talking

    "extensibility" is not really the issue, and I don't think we
    need to change the grammar for this reason</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; However, the
    processing should tolerate (by ignoring) #t=morning or
    #t=wallclock:10,25</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; That has nothing to
    do with syntax or validity.</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; So for the
    extensionsegment syntax change, I would vote again, as it
    doesn't fix ISSUE-19</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; ISSUE-19 requires
    more sweeping changes to the spec</p>

    <p class='phone'>Philip, we will wait for 12:15 you're back,
    don't worry</p>

    <p class='phone'>thanks for your comment, and by "again", I
    guess you meant "against" ?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; yes</p>

    <p class='phone'>furthermore, everybody agrees that #t=morning
    or #t=wallclock:10,25 should be ignored (good point)</p>

    <p class='phone'><cite>scribe:</cite> these are not and will
    never be media fragments 1.0</p>

    <p class='phone'>ISSUE-19?</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; ISSUE-19 --
    Parsing must be defined normatively in the MF spec itself --
    open</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; <a href=

    <p class='phone'><cite>Philip:</cite> there is nothing in the
    grammar that says where %-decoding and utf-8 decoding
    happen<br />
    ... perhaps the %-decoding is specified in the uri spec</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; %-decoding is indeed
    defined in rfc3986 (especially for non delims/sub-delims)</p>

    <p class='phone'>Philip, it is written in 4.2</p>

    <p class='phone'>A specification of the parsing algorithm to
    extract these from an actual URI can be found in D.1 Processing
    name-value components and D.2 Processing name-value lists. Note
    that the URI works on octet strings, but the parsed name-value
    pairs are unicode strings, since percent-encoding is resolved.
    Percent-decoding of non-(delims/sub-delims) may happen anytime,
    so we consider it is done for the sake of readability of the
    grammar. The following definitions</p>

    <p class='phone'><cite>Philip:</cite> let's go back to
    ISSUE-19</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; I agree with
    issue-19</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; I think the proposed
    changes are trying to realize the requirements that you wrote
    in issue-19</p>

    <p class='phone'>yes silvia</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; Old proposal was</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; mediasegment =

    timesegment / spacesegment / tracksegment ) *( "&amp;" (
    timesegment / spacesegment / tracksegment )</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; New proposal is:</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; mediasegment =
    namesegment / axissegment / extensionsegment</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; extensionsegment =

    <p class='irc'>&lt;<cite>silvia</cite>&gt; I tend to agree with
    Jack</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; I thought that we were
    happy to have the grammar+text, and other people would work on
    an algorithm</p>

    <p class='phone'><cite>Raphael:</cite> the ISSUE-19 mentions 3
    things<br />
    ... be rigid on the grammar to flag errors for validator ...
    this is what the grammar is used for<br />
    ... allow graceful extensibility ... this is dealt with the
    proposal change in the production rules<br />
    ... match what most scripting languages do currently ... no
    evidence that what we have made go agains this<br />
    ... so I don't see why ISSUE-19 is not resolved</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; New proposal
    is:</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; mediasegment =
    namesegment / axissegment / extensionsegment</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; extensionsegment =
    extensionprefix '=' extensionparam</p>

    <p class='irc'>&lt;<cite>raphael</cite>&gt; + prose to state
    that a media segment cannot be only an extension segment</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; + warning to say that
    it should not conflict with an existing axis</p>

    <strong>ACTION:</strong> troncy to edit section 7.1 for taking
    into account the cropping resolution [recorded in <a href=
    "http://www.w3.org/2010/11/02-mediafrag-minutes.html#action03">http://www.w3.org/2010/11/02-mediafrag-minutes.html#action03</a>]</p>

    <p class='irc'>&lt;<cite>trackbot</cite>&gt; Created ACTION-198
    - Edit section 7.1 for taking into account the cropping
    resolution [on Raphaël Troncy - due 2010-11-09].</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; My suggestion for
    ISSUE-19 is still &lt;<a href=
    "http://lists.w3.org/Archives/Public/public-media-fragment/2010Aug/0005.html%3E">http://lists.w3.org/Archives/Public/public-media-fragment/2010Aug/0005.html&gt;</a>
    and what would necessarily follow.</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; foolip, that is the
    meta rule I tried to suggest above</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; Yves, do you think
    the production rule can be changed accordingly?</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; silvia, indeed</p>

    <p class='phone'>Yves thinks that this resolve nothing</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; you can then make
    name and value utf8string</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; 'npt' is ascii so
    utf8, saying that it's just an utf-8 encoded string doesn't add
    anything, it in fact removes that fact that it's 'npt'</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Of course it's not
    the whole solution, it's step 1.</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; yeah, you continue
    with what is there, just as a type of namevalue</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; the algorithm should
    say that 1/ cut at &amp;, then name=value, 3/ it's utf-8, 4/ if
    npt do this...</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; but that is orthogonal
    to having the grammar saying what are the valid values</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; With this grammar,
    there's no need for the first algorithm in section D.</p>

    <p class='irc'>&lt;<cite>silvia</cite>&gt; I guess we have two
    diverging views here: the grammar is a production rule and the
    algo in section D is a dissecting approach</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; I heard.</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; But, I think it
    would be more fruitful to actually see what the alternative
    is.</p>

    <p class='phone'><cite>Raphael:</cite> I will talk with Erik
    offline, and push for the status quo as the spec is written
    today and go with the risk of having a formal objection at some
    point</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; foolip we can't have
    grammar = "name = value" , then "name = 'npt' | 'track'" and
    values ' npttime | utf8string' , so the grammar can't start
    with a generic name = value</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; however, a parsing
    algorithm might perfectly well say that</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; those are different
    things</p>

    <p class='irc'>&lt;<cite>foolip</cite>&gt; Yves, of course, the
    grammars for each dimension operate on the *result* of
    splitting name-value pairs, it's not in one layer of
    syntax.</p>

    <p class='irc'>&lt;<cite>Yves</cite>&gt; the grammar can
    operate on the splitting of '&amp;' as otherwise
    &lt;nptname&gt; = &lt;trackvalue&gt; would be ok</p>
