    Html5video Html5video Presentation Transcript

    • INTERNET KILLED THE VIDEO STAR An in-depth look at HTML5’s <video> tag
    • WHO I AM • Ben Wilkins • Director of Interactive Media atagency) Talstone Group (an advertising • A husband and a father • A die-hard fan of the Kentucky Wildcats
    • WHAT IS HTML5 VIDEO? HTML5 video is an element introduced in the HTML5 draft specification for the purpose of playing videos or movies, partially replacing the object element.* *Wikipedia
    • WHAT IS HTML5 VIDEO? • A DOM object played directly by the browser’s built-in player • Does not require 3rd party plugins • Still evolving
    • FLASH vs. HTML5
    • FLASH vs. HTML5 • Flash growth depends on Adobe support • HTML5 video reduces load time • Interaction and skins for HTML5 video can be customized using JavaScript and stylesheets • HTML5companies by all of the major internet is supported
    • DOWNSIDES • Limited full screen support • Not supported by older browsers (*cough* Internet Explorer *cough*) • It’s technically in beta • Everyone wants a different codec
    • BROWSER SUPPORT FireFox 3.5+, Safari 3.0+, Chrome 3.0+, Opera 10.5+, iPhone/iPad 1.0+, Android 2.0+ And...
    • BROWSER SUPPORT
    • CODECS & CONTAINERS H.264 and AAC (.mp4) • H.264 developed by MPEG group (2003) • MP4 developed by Apple • Uses AAC audio codec • H.24 is patent-encumbered
    • CODECS & CONTAINERS Theora and Vorbis (“Ogg”, .ogv) • Developed by Xiph.org Foundation • source-friendly Royalty-free, open standard and open • Unencumbered by any known patents
    • CODECS & CONTAINERS VP8 and Vorbis (“WebM”, .webm) • Announced May • Development sponsored by Google • Most promising container thus far
    • CODECS & CONTAINERS A year from now, the landscape will look drastically different, largely due to WebM: IE FIREFOX SAFARI CHROME OPERA IPHONE ANDROID Ogg — 3.5+ ** 5.0+ 10.5+ – – MP4 9.0+ – 3.0+ 5.0+ – 3.0+ 2.0+ WebM 9.0+* 4.0+ ** 6.0+ 10.6+ – *** * Microsoft has implied that the user has to install a VP8 codec, but nothing has been confirmed. ** Safari will play anything QuickTime can play, but QT only comes with MP4 support pre-installed. *** Google has committed to supporting WebM “in a future release” of Android, but has not set a timeline.
    • CODECS & CONTAINERS Which should I use? • You need to use ALL OF THEM. • FireFox will continue to reject MP4 as long as the MPEG group continues to charge a licensing fee for encoding & decoding. • Apple will continue to reject Ogg because FireFox is rejecting MP4. • Google can try to convince Apple to use WebM, which would make it compatible with every browser and device.
    • ENCODING: MP4 • QuickTime Pro ($30) • HandBrake (Free)
    • ENCODING: OGG • FireFogg: A free plug-in for FireFox • Encoded locally • Open source with an API available for use
    • ENCODING: WEBM • Can now also be done with FireFogg • WebM is also supported(CLI) a command line interface in ffmpeg,
    • MARKING IT UP Technically, all you need is: <video src=”trailer.webm”></video> However, if you’ve been paying attention, you know we need more.
    • MARKING IT UP Just like images, you should add width and height: <video src=”trailer.webm” width=”320” height=”240”></video>
    • MARKING IT UP Let’s remove the source for now and add controls. <video width=”320” height=”240” controls></video>
    • MARKING IT UP Preloading... just hear me out. If the whole point of the page is to view the video, it makes sense to have the browser start downloading the video as soon as the page loads. <video width=”320” height=”240” controls preload></video> Telling the browser NOT to preload: <video width=”320” height=”240” controls preload=”none”></video>
    • MARKING IT UP Autoplay... just hear me out, again. Some people hate autoplay, some love it. The truth is that sometimes it’s the correct thing to do. <video width=”320” height=”240” controls autoplay></video>
    • MARKING IT UP Before I go on, I should mention MIME Types. Place the following lines in your .htaccess file to send the correct MIME Types to browsers. AddType video/ogg .ogv AddType video/mp4 .mp4 AddType video/webm .webm * If your video won’t play in FireFox, this is likely the reason why. Make sure the video/ogg MIME Type has been added correctly.
    • MARKING IT UP Adding the source back, but this time I’m going to add all three codecs. The video element can contain more than one source, and the browser will go down the list until it finds one it can play. <video width=”320” height=”240” controls autoplay> <source src=”trailer.mp4” type=”video/mp4”> <source src=”trailer.webm” type=”video/webm”> <source src=”trailer.ogv” type=”video/ogg”> </video> Adding the type attribute lets the browser know if it can play the file.
    • MARKING IT UP: A FALLBACK PLAN But what about IE? • Most people that use IE also have Flash installed, and the modern versions of Flash support H.264 video, so you can use the MP4 you already encoded. • HTML5 let’s you nest an <object> element inside the <video> tag. • FlowPlayer is a free Flash video player.
    • MARKING IT UP: A FALLBACK PLAN • HTML5 will ignore all children of the <video> element (other than <source>). • This allows you to use HTML5 in newer browsers and gracefully fall back to Flash in older browsers. • Video forand others have expanded on it popular, Everybody made this method since.
    • MARKING IT UP: iOS ISSUES • Prior to iOS4, videos were not recognized if a poster attribute is included. The poster attribute lets you display a custom image while the video loads or until the user presses play. • iOSlisted,onlylist your MP4 file first. file will so recognize the first source
    • MARKING IT UP: ANDROID ISSUES • The type attribute on the source element confuses Android. Since Android can only read H.264, just leave off the type attribute for the MP4 file. This does not affect other browsers. • The controls attribute is not supported, but it doesn’t hurt anything to include it.
    • THE FULL CODE <video id="movie" width="320" height="240" preload controls> <source src="trailer.mp4" /> <source src="trailer.webm" type="video/webm" /> <source src="trailer.ogv" type="video/ogg" /> <object width="320" height="240" type="application/x-shockwave-flash" data="flowplayer-3.2.1.swf"> <param name="movie" value="flowplayer-3.2.1.swf" /> <param name="allowfullscreen" value="true" /> <param name="flashvars" value='config={"clip": {"url": "http://example.com/vids/trailer.mp4", "autoPlay":false, "autoBuffering":true}}' /> <p>Download video as <a href="trailer.mp4">MP4</a>, <a href="trailer.webm">WebM</a>, or <a href="trailer.ogv">Ogg</a>.</p> </object> </video> <script> var v = document.getElementById("movie"); v.onclick = function() { if (v.paused) { v.play(); } else { v.pause(); } }); </script>
    • GOING FORWARD • More useful analytics • Easier social sharing • Easy branding • Calls to action and tracking • Email capabilities • Who knows... Maybe TV?
