  22       <div class="date">16th January 2011</div>
  23       <div class="body"><p>The video format struggle on the web continues, and the three
  24 contenders seem to be Ogg Theora, H.264 and WebM.  Most video sites
  25 seem to use H.264, while others use Ogg Theora.  Interestingly enough,
  26 the comments I see give me the feeling that a lot of people believe
  27 H.264 is the most supported video format in browsers, but according to
  28 the Wikipedia article on
  29 <a href="http://en.wikipedia.org/wiki/HTML5_video">HTML5 video</a>,
  30 this is not true.  Check out the nice table of supprted formats in
  31 different browsers there.  The format supported by most browsers is
  32 Ogg Theora, supported by released versions of Mozilla Firefox, Google
  33 Chrome, Chromium, Opera, Konqueror, Epiphany, Origyn Web Browser and
  34 BOLT browser, while not supported by Internet Explorer nor Safari.
  35 The runner up is WebM supported by released versions of Google Chrome
  36 Chromium Opera and Origyn Web Browser, and test versions of Mozilla
  37 Firefox.  H.264 is supported by released versions of Safari, Origyn
  38 Web Browser and BOLT browser, and the test version of Internet
  39 Explorer.  Those wanting Ogg Theora support in Internet Explorer and
  40 Safari can install plugins to get it.</p>
  41
  42 <p>To me, the simple conclusion from this is that to reach most users
  43 without any extra software installed, one uses Ogg Theora with the
  44 HTML5 video tag.   Of course to reach all those without a browser
  45 handling HTML5, one need fallback mechanisms.  In
  46 <a href="http://www.nuug.no/">NUUG</a>, we provide first fallback to a
  47 plugin capable of playing MPEG1 video, and those without such support
  48 we have a second fallback to the Cortado java applet playing Ogg
  49 Theora.  This seem to work quite well, as can be seen in an <a
  50 href="http://www.nuug.no/aktiviteter/20110111-semantic-web/">example
  51 from last week</a>.</p>
  52
  53 <p>The reason Ogg Theora is the most supported format, and H.264 is
  54 the least supported is simple.  Implementing and using H.264
  55 require royalty payment to MPEG-LA, and the terms of use from MPEG-LA
  56 are incompatible with free software licensing.  If you believed H.264
  57 was without royalties and license terms, check out
  58 "<a href="http://webmink.com/essays/h-264/">H.264 – Not The Kind Of
  59 Free That Matters</a>" by Simon Phipps.</p>
  60
  61 <p>A incomplete list of sites providing video in Ogg Theora is
  62 available from
  63 <a href="http://wiki.xiph.org/index.php/List_of_Theora_videos">the
  64 Xiph.org wiki</a>, if you want to have a look.  I'm not aware of a
  65 similar list for WebM nor H.264.</p>
  66
  67 <p>Update 2011-01-16 09:40: A question from Tollef on IRC made me
  68 realise that I failed to make it clear enough this text is about the
  69 &lt;video&gt; tag support in browsers and not the video support
  70 provided by external plugins like the Flash plugins.</p>
