What is HTML5? -  HTML 2.0: 1995 -  HTML 3.2: 1997 -  HTML 4.0: 1998 -  XHTML 1.0: 2000 -  XHTML 1.1: 2001 -  … -  … -  HTML5: 201x


What is HTML5? HTML5 ≈ HTML + CSS + JS

-  Integrates multimedia: -  2D & 3D drawing (Canvas, WebGL) -  Audio and video playback -  Native SVG support

-  New semantic elements: -  <nav>, <footer>, <figcaption>, <section>

-  Lots of other useful features:

-  Geolocation -  Persistent offline storage (blob, SQL) -  Multithreaded JS (“web workers”) -  Web fonts

-  Extensive overview: http://slides.html5rocks.com/

HTML5: possibilities Limitless possibilities! -  Webapps -  Games -  Multimedia

HTML5 and Video Support for playing video directly from the browser

<video id="movie" width="320" height="240" preload controls>

<source src="MY_MOVIE.mp4" />

<source src="MY_MOVIE.webm" type='video/webm />

Video formats for HTML5 -  Video/audio codec support depends

on browser/platform -  Lots of politics involved

-  Platforms support own media format: -  Apple supports Quicktime in OSX/iOS -  Microsoft supports WMV in Windows


Cross-platform Formats 3 cross-platform formats: -  H.264 -  Ogg -  WebM


Cross-platform Formats H.264: -  MP4 container -  H.264 video (baseline/main/high) -  AAC audio

o  Modern codecs with high compression rate o  Widely supported o  Hardware implementation available o  Very good video-encoders available (x264) o  Licensing fees required


Cross-platform Formats Ogg: -  Ogg container -  Theora (VP3) video -  Vorbis audio o  Slightly dated video codec o  Decent quality video o  No hardware implementations o  Not very widely supported o  Open format, free to use


New kid on the block WebM: -  VP8 video -  Vorbis audio -  Simplified Matroska container

o  Open and Free o  Slightly less advanced than H.264 o  Support growing rapidly

o  Problems: -  Ulterior motives? -  Possible patent issues


New kid on the block

“A key factor in the web’s success is that its core technologies such as HTML, HTTP, TCP/IP, etc. are open and freely implementable. Though video is also now core to the web experience, there is unfortunately no open and free video format that is on par with the leading commercial choices. To that end, we are excited to introduce WebM, a broadly-backed community effort to develop a world-class media format for the open web.”

Client support


No single cross-platform format -  Need H.264 and (WebM or Ogg) Mobile world even more problematic.

Nothing settled yet How quickly will IE9 and Firefox 4 be adopted? Lots of developments: -  H.264 will stay free for consumers -  Adobe Flash will support WebM -  Google supports WebM in Internet Explorer (!) -  Google drops support for MP4/H.264 from Chrome -  Microsoft supports MP4/H.264 in Chrome (!)

What’s next?


Why no HTML5? -  Complexity shifted to video backend -  Need to support different/multiple formats

-  Some features not available (yet?): -  DRM -  Live recordings -  RTP streaming/multicast


Conclusion


HTML5 Video is here to stay

-  Abide your time

-  But be prepared

Be prepared!

-  Get rid of proprietary formats -  Add support for Ogg or WebM

-  Possible right now: implement HTML5 video with Flash fallback
