<video>
is only going to become more
ubiquitious in the future and
is already relevant for playing
video on mobile devices.

Format Wars
* h.264 (closed)
* Ogg Vorbis (open)

HTML5 Video
Supports Any
Media.
It’s the browser that dictates
which formats are played.

on the formats that can be
utilized in HTML5 and more...

Basic Video Embed
use the browser’s
native video controls

<video width="480" height="380" controls>
<source src="trolololololololol.ogv"
type='video/ogg; codecs="theora, vorbis"'>
<source src="trolololololololol.mp4"
type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
</video>

Video With Player UI Expressed
in HTML Markup
<div id="player">
<video width="480" height="380" class="ecard">
<source src="trolololololololol.ogv"
type='video/ogg; codecs="theora, vorbis"'>
<source src="trolololololololol.mp4"
type='video/mp4; codecs="avc1.42E01E, mp4a.40.2"'>
</video>
<nav class="player_controls">
<a href="#" class="play_button">Play<span></span></a>
<a href="#" class="mute_button">Mute<span></span></a>
<progress value="0" class="play_progress">
<span></span>
</progress>
<progress value="0" class="load_progress">
<span></span>
</progress>
</nav>
</div>

CSS to Style Player UI
/* =CONTROLS
------------------------------------------------------ */
.player_controls {
bottom: -20px;
height: 70px;
left: 0;
position: absolute;
width: 480px;
z-index: 10;
}

/* =PLAY/MUTE BUTTONS
------------------------------------------------------ */
.player_controls a.play_button {
bottom: 0;
left: -38px;
}
.player_controls a.mute_button {
bottom: 0;
right: -38px;
}

Javascript to Control Video
var _MEDIA = $(’#player video.ecard’).get(0); get the
video element...
$(’.play_button’).click(togglePlay);
$(’.mute_button’).click(toggleMute);

function togglePlay(e) {
if(_MEDIA.paused) { add some simple
_MEDIA.play(); event listeners....
} else { if paused play
_MEDIA.pause(); otherwise pause...
}
return false;
};
function toggleMute(e) {
if(_MEDIA.volume > 0) {
_MEDIA.volume = 0;
} else {
_MEDIA.volume = 1; if it has volume mute
} otherwise turn on volume...
return false;
};

<video> methods & attributes
var video = $(’video’).get(0);

video.play();
video.pause();
video.paused; // Returns true if video is paused.
video.ended; // Returns true if video is over.

video.volume; // Returns volume value (between 0-1)
video.volume=0.5; // Sets volume value (between 0-1)

video.currentTime; // Current point of time in the video.

video.seekable; // Returns true if supports seeking.
video.playbackRate; // Allows you to rewind/fastforward.

Your standard
HTML/CSS/JS
workflow handles
everything.

In Flash we do
all of the legwork to
build things that are
trivial in the DOM.

Video player that loads and
displays cuepoints and
messages from a datasource.

Certain things which
may be complex in Flash
are trivial to implement
in HTML as the DOM
can do all of the
‘heavy lifting’ for you.

Both technologies still
have their purposes. It’s
important not to rally
behind technologies.
Use the right tool for the job
be it HTML5 or Flash.
