Does HTML5 support HTTP Psuedostreaming of video?

Can I click on some time and eventhough the video is not downlaoded till that time and the video starts playing from the time I clicked? If yes, what would be a better option for viewing streamed video- H开发者_高级运维TML5 or flash player like JW player? WHich one will have less lag?

HTML5 browsers generally don't support this, however I believe the video tag in Safari will work with the Apple HTTP Streaming format for this functionality. For something that works across all browsers, Flash Player can do it using either RTMP streaming or HTTP Streaming (either with our without OSMF to support this). Probably the easiest place to start is with OSMF, which supports both RTMP and HTTP streaming of video.

I have tested this with Firefox and Firebug and while you can "seek" to a point in the video without having to watch video preceding the point you wish to seek, this still causes the entire video file to download.

Indeed, each time you seek in Firefox 4, the entire video downloads.

This may change and improve as HTML 5 video implementations become more mature and may differ based on the actual browser being used.
