HTML5 Video, minus Ogg

Mozilla, the makers of Firefox, refuse to support the MP4/H.264 standard because it isn’t open-source and free from licensing constraints. Without Ogg, Firefox’s HTML5 video is rendered useless and requires a Flash-based fallback system. However, Firefox’s handling of the video element breaks the fallback mechanism. A scripted solution is required.

Here’s a simple script that will detect whether HTML 5 video is supported in the browser, and if it is, will check to see if this is Firefox. If yes, it deletes the specified video element but leaves the Flash fallback in its place.

But as I hear more from these seasoned SCORM pros, I’ve made (what I believe to be) an interesting observation: there is a sharp division between die-hard SCORM developers and casual users. I suppose I’ve felt this way for a long time, but it’s really coming into focus this week. Let me try to define the camps.

Gotchas in Internet Explorer 8

Internet Explorer 8 (IE8) is at Release Candidate 1, which means it will be released very shortly.

However, because of some of these changes, it is also widely understood that IE8 might ‘break’ websites that have relied on IE-specific hacks targeted at previous versions if Internet Explorer.
