Putting a +good set of HTML tags together to get working embedded video in all +browsers and across all operating systems is not easy. I hope this +will become easier when the &lt;video&gt; tag is implemented in all +browsers, but I am not sure. We provide the recordings in several +formats, MPEG1, Ogg Theora, H.264 and Quicktime, and want the +browser/media plugin to pick one it support and use it to play the +recording, using whatever embed mechanism the browser understand. +There is at least four different tags to use for this, the new HTML5 +&lt;video&gt; tag, the &lt;object&gt; tag, the &lt;embed&gt; tag and +the &lt;applet&gt; tag. All of these take a lot of options, and +finding the best options is a major challenge.</p> + +<p>I just tested the experimental Opera browser available from <a +href="http://labs.opera.com">labs.opera.com</a>, to see how it handled +a &lt;video&gt; tag with a few video sources and no extra attributes. +I was not very impressed. The browser start by fetching a picture +from the video stream. Not sure if it is the first frame, but it is +definitely very early in the recording. So far, so good. Next, +instead of streaming the 76 MiB video file, it start to download all +of it, but do not start to play the video. This mean I have to wait +for several minutes for the downloading to finish. When the download +is done, the playing of the video do not start! Waiting for the +download, but I do not get to see the video? Some testing later, I +discover that I have to add the controls="true" attribute to be able +to get a play button to pres to start the video. Adding +autoplay="true" did not help. I sure hope this is a misfeature of the +test version of Opera, and that future implementations of the +&lt;video&gt; tag will stream recordings by default, or at least start +playing when the download is done.</p> + +<p>The test page I used (since changed to add more attributes) is +<a href="http://www.nuug.no/aktiviteter/20090113-foredrag-om-foredrag/">available +from the nuug site</a>.

I was unable +to find a way to get the URL of the playing video out of Opera, so I +am not quite sure it picked the Ogg Theora version of the video. I +sure hope it was using the announced Ogg Theora support. :)</p> + + + Fiksgatami begynner å ta form Fiksgatami_begynner____ta_form.html @@ -364,23 +415,5 @@ of these cards.</p> - - Mekanikk-delen av reprap-byggesettet på vei - Mekanikk_delen_av_reprap_byggesettet_p___vei.html - Mekanikk_delen_av_reprap_byggesettet_p___vei.html - Tue, 2 Dec 2008 12:00:00 +0100 - -<p>Endelig fikk jeg beskjed om at mekanikkbyggesettet er sendt fra -England.
