Hi all,<br>
<br>
The W3C WG for media fragments has published a Last Call Working Draft<br>
at <a href="http://www.w3.org/TR/media-frags/" target="_blank">http://www.w3.org/TR/media-frags/</a> .<br>
<br>
The idea of the spec is to enable addressing sub-parts of audio-visual<br>
resources through URIs, such as <a href="http://example.com/video.ogv?t=10,40" target="_blank">http://example.com/video.ogv?t=10,40</a><br>
to address seconds 10-40 out of video.ogv. This is relevant for use in<br>
the <audio> and <video> elements and can help focus the playback to a<br>
specific subpart.<br></blockquote><div> </div><div><br></div><div>When dealing with timed content - shouldn't there be a relative URI meaning from the current time to the designated time. I'm thinking of something like:</div>
<div><a href="http://example.com/video.ogv#t=,40">http://example.com/video.ogv#t=,40</a></div><div>Which would be used to continue a piece a playing media up to the 40 second point and then stop.</div><div><br></div><div>
This could prevent a fetch by the UA to the start of the media fragment which could be especially useful if the media is marked as no-cache.</div><div><br></div><div>I'm thinking an article could outline links on a page each of which would cause a related video to continue playing up to the point specified in the link and then stop - giving the reader a chance to catch up.</div>
<div><br></div><div>This also brings up the matter of link targets. Shouldn't I be able to do something like this:</div><div><br></div><div><video name="presentation"></video></div><div><a href="#,50" target="presentation">Next Slide</a></div>
<div><br></div></div>
