As part of the work we do in NUUG -to publish video recordings of our monthly presentations, we provide a -page with embedded video for easy access to the recording. 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 <video> 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 -<video> tag, the <object> tag, the <embed> tag and -the <applet> tag. All of these take a lot of options, and -finding the best options is a major challenge.
- -I just tested the experimental Opera browser available from labs.opera.com, to see how it handled -a <video> 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 -<video> tag will stream recordings by default, or at least start -playing when the download is done.
- -The test page I used (since changed to add more attributes) is -available -from the nuug site. Will have to test it with the new Firefox -too.
- -In the test process, I discovered a missing feature. 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. :)
+En standard er noe man samler seg rundt, ut fra ideen om at en får +fordeler når mange står sammen. Jo flere som står sammen, jo +bedre. Når en vet dette, blir det litt merkelig å lese noen av +uttalelsene som er kommet inn til +høringen +om versjon 2 av statens referansekatalog over standarder. Blant +annet Abelia, NHO og Microsoft tror det er lurt med flere standarder +innenfor samme område. Det blir som å si at det er fint om Norge +standardiserte både på A4- og Letter-størrelser på arkene, ulik +sporvidde på jernbaneskinnene, meter og fot som lengemål, eller +høyre- og venstrekjøring - slik at en kan konkurrere på hvilken +standard som er best. De fleste forstår heldigvis at dette ikke +bidrar positivt.
