The website is using h.264 at ~3Mbps in a QuickTime movie container in <video> elements. It'll work for anyone with the following conditions met:

- Using a browser that supports the QuickTime container format (i.e., has the QuickTime or compatible plugin installed)

- Using a browser that supports the <video> element with the h.264 codec (not Firefox).

- Using a device that can decode 3Mbps h.264 video (not iOS devices).

This is more for the sibling comments, but on Hacker News, I'd expect people to take a minute to check why something is or isn't working for them on a page instead of just commenting what browser/OS combo they're using.

Oh, but I checked why it is not working as soon as I saw "Video format or MIME type is not supported.". Just to see that the extension of the video file is mov and of course it would not play in my FF-Win7.

As for your points:

- installing QuickTime is not an option (in my opinion it's a piece of bloatware crap that should be retired)

- why should I not use Firefox? just because it chose to support only open video formats

- last time I checked iOS devices sold way more than Macs and I bet a lot of people check out HN using them

Problem: the page is more or less only addressed to people using MacBooks and Windows/Chrome !?! (maybe should include that in the HN link to the article)

Solution: it only takes 10-15 minutes to convert the videos to ogv or webm and add new source tags to the code for fallback thus making the page accessible to the rest of the world

P.S. I did not mean for my first comment to sound like a snarky remark (the blood rush to the brain took over for a moment). I should have included more details about the nature of the problem. Cheers.

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.

The videos can't be played on my iPad 2, too.

Windows, FF.

Wow. Looking at my sibling comments, this is some full spectrum incompatibility. Abandon ship on these videos!

Windows, FF as well. It needs the divx plugin but then works flawlessly.

Granted, needing additional plugins is kind of bad. But I don't know an easy way to embed very short videos so it's as good a solution as any.

Isn't this supposed to be the problem that HTML5 video tag solves?

Can't either on Firefox/OSX.

Videos are working fine for me.

Chromium + Debian

but don't work in firefox on debian

Doesn't work in Firefox for me but does work in Midori

Doesn't work on chrome windows, or firefox windows.

Works for me on both.

Works on Chrome OS on cr-48/Mario as well.
