Like I said, the last line of my comment was more directed towards the sibling comments: you at least recognized the basic issue, which is a reliance on Apple—or more specifically, Mac+WebKit—without a concern for cross-compatibility.

To that point, the list of conditions I presented weren't normative, they were descriptive. The videos won't work in Firefox because Firefox doesn't support h.264. Likewise, they won't work on iOS devices because even the latest generation only decodes 2.5Mbps h.264 video. So 10 comments listing all the browser combinations people tried is pure noise: taking a minute to look at the video would've been enough to know which browser/OS combinations were going to work.
