1) HTML5 browsers need a video player plugin
2) Prior browsers need a video player plugin
therefore
3) HTML5 still doesn't play video any more natively than prior versions.
4) The video features that HTML5 promises have already been available in previous browsers.
The difference between Flash and HTML5 for video (which is not what Flash was originally designed for)?
From the Exposure Room web page linked above:
We did some extensive tests during the course of developing our player and find that the playback performance of IE 9 [Win] and Safari [Mac] are extremely good (almost as efficient as the native players on their respective platforms). So much so that they are far better than any Flash based video player (including ours).
I'm not talking about flash vs. non-flash at all (and by the way, i agree that flash players are garbage). Exposure Room could have implemented the same technology in non-flash plugins for older browsers. HTML5 still has nothing to do with it.
The same way it's done with flash plugins, or any other plugins.
Note that HTML5 doesn't specify the video format nor do HTML5 browsers play the video content. The server still serves up ... some format ... of video file and the browser still uses ... some plugin ... to play the video. Contrast that to HTML4 or HTML3 where the server serves up ... some format ... of video file and the browser uses ... some plugin ... to play the video. Sure, HTML5 uses the < video > tag instead of the < embed > tag. So what? I don't see any change in the process. Maybe the new plugins are better, but that's simply because the new plugins are better, as are most new versions of any software, not because they're designed for HTML5.
Flash video is always viewed with a separately downloaded plug-in that together with Adobe Reader is responsible for about 70% of security holes on PCs.
HTML5 video doesn't require downloading a separate plug-in, doesn't have the security issues of the Flash architecture, and allows immediate viewing by the at least tens of millions of people who are using flash blockers to avoid pesky blinking flash ads, or are using one of the hundreds of millions of mobile devices with permanent flash blockers (iPhones, iPads, 99% of Android phones and gadgets, as well as all the other smartphones).
That, too, is the hype i've heard and it does sound good indeed!
But, if it's true, why is Exposure Room making a player for HTML5? Either it's completely redundant and unnecessary, or HTML5 actually does need a plugin to play the video. Which is it?
Most of the technical descriptions i've seen of HTML5 indicate it's the latter, and that HTML5 browsers do not in fact come with the ability to play video natively. And i that's true, then what's the point and why the hoopla?
Why are there 50 flash players if only one is needed?
Because they have different feature sets that people are willing to pay good money for.
XR indicated on their web site that they were doing it for the new features made possible by HTML5, and the substantial performance boost (compared to flash) when playing back higher resolution videos.
