### Fun (With) Video

Been rather busy with other matters, but I thought I would share a cool little physics video with you.

Aside from the nifty physics, it’s an opportunity to give the HTML5 <video> element a spin. Should work out-of-the-box in Firefox and Opera, Safari users will have to download the Ogg/Theora Component for Quicktime (available for Mac and Windows).

Alas, there’s no support for posting videos in the comments. Comments must be strictly valid XHTML 1.1; only I am allowed to say

### Iceweasel

I don’t think Iceweasel/3.0.6 supports the <video> element.

Tried with Opera and Firefox on Mac (10.5.6) and it doesn’t seem to work: i also only see gray lines.

As with Safari, i’m running 4Beta… so… i get the controls but nothing plays… (i thought i had the plugin installed, but will try once again.)

[]’s.

Spoke too soon: i guess i didn’t have the plugin installed. :-(

Just tested it with Safari 4Beta and it works just fine. :-)

Hmm. With Firefox 3 on an Intel Mac Mini (OS 10.4), I see no sign of any video at all. With Firefox 3.1b2 on a Powerbook (OS 10.5), I see little more than empty space where the first video is supposed to be (it sprouts a control bar when I mouse over it), and the second one gives me a weird grainy blue-tinted negative view of a large-hatted Mexican bandit without a badge (with no sound, as far as I could tell).

Looks like HTML5 video isn’t quite ready for prime time yet!

No joy with Opera 9.64 on Vista.

Nor with Firefox 3.0.1 on CentOS 5.0 (Linux 2.6.9)

### Firefox 3.0.x

You will not have any joy with Firefox 3.0.x. You’ll need at least 3.1β. The public betas are pretty solid. For more excitement, you can try a nightly build.

Hey, great to see you experimenting with the element, and supporting free formats!

That in indeed a fun video. What are we looking at? I gather there’s some 3d liquid surface fingering under an (electric?) field?

It’s a ramping magnetic field. The liquid is a droplet of ferrofluid, trapped between two glass plates.

The “video” itself is crudely stitched together from a series of still photos. But it gives a pretty good idea of this cool phenomenon.

Having a “safe” way to include multimedia is important to me.

Well Jacques,

I still can’t see your video - by any of the adverstised means. I thought the whole idea of web technology was to provide open communication? I seems that people still like to work in esoteric corners that leave the rest of us detached.

### Take the long view

Patience, patience.

The reason why (from my perspective) <video> is important is that, unlike <object> or <embed> (the traditional methods for embedding video), it can’t be used to embed malicious content. So it’s safe to allow it to pass through (not be stripped-out) in aggregators (like the one that runs Planet Musing) and in Wiki software (like Instiki) and in blog comments (well, OK, not yet here).

That’s a positive development. One which you, too, will ultimately benefit from.

Is it physics? Some regulated version of a brown octopus swimming in an orange lemonade. ;-)

Not sure what kind of obsolete browsers everyone is using instead of Firefox 3.1 beta 3. Even though, I admit, the newest Chrome 2.0.169.1 that I use most of the time sees nothing, either.

### Re: Fun (With) Video

I can watch the video using the Firefox 3.1 beta. However, audio is not functioning. What might be wrong?

### Re: Fun (With) Video

If you can hear the sound in the second video, … nothing. The first video doesn’t have an audio track.

### Re: Fun (With) Video

The video tag is now enabled in Google Chrome 3.0 beta.

Unfortunately, this achievement isn’t animated because my OGG plugins are no good in Chrome.

Moreover, the video tag in Chrome has made viewing SWF, SVG, and even bare TXT files impossible in the browser, replacing them with a dull silent video player, a bug that will surely be fixed on one day. :-)
