The Media Fragments Module

One W3C spec­i­fi­ca­tion which seems to have slipped below most peo­ple’s radar is Media Frag­ments 1.0, which moved to Can­di­date Rec­om­men­da­tion sta­tus in Decem­ber last year. Media Frag­ments is a syn­tax which extends the URLs of media files so that only select­ed por­tions are made avail­able to the user; let me explain that fur­ther with a cou­ple of examples.

Playing WebM in Safari with plugins

As you‚Äôre no doubt aware, HTML5 video is this year‚Äôs big thing ‚ÄĒ but there‚Äôs a dis¬≠pute going on about which should become the default stan¬≠dard video codec. The cur¬≠rent nascent de fac¬≠to stan¬≠dard is H.264, but recent¬≠ly the new WebM for¬≠mat is gain¬≠ing traction.

I‚Äôve no idea how the web video for¬≠mat war will end. My pref¬≠er¬≠ence is that a free, non-patent encum¬≠bered, high-qual¬≠i¬≠ty video codec will become the stan¬≠dard, and WebM is the best fit for that descrip¬≠tion. Despite the recent announce¬≠ment by the MPEG LA, the patent pool which con¬≠trols licens¬≠ing of H.264, that it will always be free for ‚Äėvideo deliv¬≠ered to the inter¬≠net with¬≠out charge‚Äô, that still does¬≠n‚Äôt make it free-as-in-speech, and still not free-as-in-beer for any¬≠one want¬≠i¬≠ng to build a busi¬≠ness around video encoding/decoding (which includes, if I‚Äôm not mis¬≠tak¬≠en, bundling it with a brows¬≠er). All that said, my pref¬≠er¬≠ence is mean¬≠ing¬≠less in the face of so many vest¬≠ed busi¬≠ness interests.

Encoding Video for Android

In my pre­vi­ous post, Mak­ing HTML5 Video work on Android phones, I said that you have to encode your videos as .m4v in order for them to work in Android. This isn’t actu­al­ly cor­rect. The suf­fix can be either .mp4 or .m4v, what mat­ters is the way the video is encoded.

Now, there are loads of blog and forum posts which give dif¬≠fer¬≠ing advice on pre¬≠sets and para¬≠me¬≠ters, and I‚Äôm no expert ‚ÄĒ so what I‚Äôll do is just show you two quick ways that worked for me (I have a Sam¬≠sung Galaxy S).

Making HTML5 Video work on Android phones

I recent­ly became the own­er of an Android phone* and found that, despite it being list­ed as a fea­ture of the brows­er, the HTML5 video ele­ment did­n’t work for almost all of the exam­ples I tried. I’ve just done some exper­i­men­ta­tion with this and think I’ve found a solu­tion, so this post is offered in the hope that it helps any­one who may be tear­ing their hair out over the same problem.

Building a better HTML5 video player with Glow

Last year I wrote a post (Build¬≠ing HTML5 video con¬≠trols with JavaScript) intro¬≠duc¬≠ing the HTML5 Media Ele¬≠ments API and demon¬≠strat¬≠ing a sim¬≠ple set of con¬≠trols for play¬≠ing video.

In this (some­what belat­ed) fol­low-up I’m going to explore build­ing a more inter­ac­tive set of con­trols using a JavaScript UI library; I’m going to use Glow, but it could eas­i­ly be adapt­ed to jQuery UI or similar.

Building HTML5 video controls with JavaScript

The HTML5 video ele­ment is now includ­ed in Fire­fox, Safari & Chrome, and on its way in Opera. By using JavaScript to access the media ele­ments API it’s easy to build your own cus­tom con­trols for it; in this arti­cle I’m going to show how I built a (very) basic con­trol interface.

Aside

I‚Äôve updat¬≠ed my Speak¬≠ing page to include more con¬≠fer¬≠ences, more videos, and a lit¬≠tle on my speak¬≠ing require¬≠ments and pref¬≠er¬≠ences. I‚Äôm plan¬≠ning to cut down on the num¬≠ber of talks I give in 2014 (twelve is too many), but am always open to inter¬≠est¬≠ing offers and oppor¬≠tu¬≠ni¬≠ties, so please get in touch if you‚Äôre organ¬≠is¬≠ing an event.
