Since HTML5 doesn't have an official video file format yet and fullscreen support isn't in all browsers, I've been wondering if Chrome, Safari, or Firefox can be instructed to have their HTML5 video players replaced with VLC and how I can go about setting that up (PC/Mac owner here).
I know that plugins are supposedly full of security issues, but I believe more of it has to do with flash than anything else. Anyways, in my opinion it would be a good idea if everyone could choose the browser's default HTML5 video player. This way, we won't have to worry about lack of support for true fullscreen, nor mp4, WebM and OGV. Also, I'm not doing beta browsers since they very easily turn buggy.
Vimeo and many other sites would be great for HTML5 if this is currently possible.
