Like many web developers I'm looking forward to streaming video that utilizes the new HTML 5 <video> tag. Browser support definitely isn't wide enough yet, so using a Flash/SWF fallback is a must.
This got me thinking: in Flash it's possible to highly customize the playback controls (pause, play, stop, seek, volume, etc.) in HTML 5?. What options are there for customizing the glyphs, icons and colors of video controls? Is Javascript required? For instance the following page renders different controls depending on the browser - tested using FF3.5, Chrome and Safari:

It would be really awesome to customize and standardize controls across browsers and even match the Flash controls used by older browsers.
