## Library Overview

[html5]: https://developer.mozilla.org/En/Using_audio_and_video_in_FireFox
[KDP3]: http://www.kaltura.org/project/Video_Player_Playlist_Widget

__Kaltura's HTML5 Media Library__ enables you to take advantage of the [html5 `<video>` and `<audio>` tags][html5] today with a consistent player interface across all major browsers including Internet Explorer. 

The library supports a seamless fallback with Flash based playback using [Kaltura's Flash player][KDP3] or Java Cortado for browsers that don't yet feature HTML5 video & audio support.  Upon detection of the client browser, the __Kaltura HTML5 Media Library__ chooses the right codec to use (specified in the source attributes, or available from a Kaltura server) and the right player to display.  So whether you're using flash, h264, ogg-theora, or WebM -- Kaltura's library will make sure it is played on all browsers with the same UI.
While support for HTML5 video is growing, there is large percentage of the web browser market that is presently best served by the Adobe Flash plugin and an associated player. A base component of the Kaltura HTML5 javascript library bridges this gap, by cascading to an underlining Flash player in browsers that do not support the native HTML5 video player. In addition, Kaltura's player maintains a unified look & feel across formats and browsers.

## Basic Usage

## Using Kaltura SaaS for Video Transcoding

To use html5 video flavors from your Kaltura account, you need only to include a `kentryid` attribute in yout `<video>` tag.  The library will automatically select the appropriate video flavors for your visitors devices (make sure you have contacted support and requested that [html5 video flavors](#codecs) be added to your account)

    <!DOCTYPE html>
    <html>
    <head>
      <script type="text/javascript" src="http://html5.kaltura.org/js" > </script> 
    </head>
    <body>
      <video kentryid="0_swup5zao"
        kwidgetid="_243342"></video>
    </body>
    </html>

## Hosting Your Own Video Transcodes

Using __Kaltura's HTML5 Media Library__ in your own applications is as simple as adding a script include of the library javascript, `http://html5.kaltura.org/js` and then using the normal html5 video tag, ie `<video src="myOgg.ogg">`.

Putting it all together your embed page should look something like this:

    <!DOCTYPE html>
    <html>
    <head>
      <script type="text/javascript" src="http://html5.kaltura.org/js" > </script> 
    </head>
    <body>
      <video id="video" style="width:544px;height:304px;" 
        poster="http://upload.wikimedia.org/wikipedia/commons/thumb/b/bd/Elephants_Dream.ogg/seek%3D13-Elephants_Dream.ogg.jpg"
        duration="10:53" 
        linkback="http://www.elephantsdream.org/" >
        <source type="video/ogg" src="http://ia311040.us.archive.org/3/items/ElephantsDream/ed_1024.ogv" >
        <source type="video/h264" src="http://ia311040.us.archive.org/3/items/ElephantsDream/ed_hd_512kb.mp4" >
        <track kind="subtitles" id="video_af" srclang="af" 
             src="media/elephants_dream/elephant.afrikaans.srt"></track>
        <track kind="subtitles" id="video_en" srclang="en"  
             src="media/elephants_dream/elephant.english.srt"></track> 
      </video>
    </body>
    </html>

* For best compatibility: we include the poster, durationHint, width and height attributes. This way browsers such as IE can display the player interface with poster image at the correct resolution with a duration in the user interface.
* If you would like to support html5 with h.264 ( safari, IE9, google chrome) and support a flash fallback for older versions of IE you include an h.264 source. For best compatibility your mp4 source should ideally use a h.264 profile compatible with mobile devices such as the iPhone.  <a href="http://corp.kaltura.com/">Kaltura hosted Solutions</a> include iPhone support. Desktop video encoding software such as <a href="http://handbrake.fr/">handbrake</a> also includes iPhone profiles. 
* If you would like to change the theme you can change the class attribute `<video class="kskin">` more info about custom theming is on the way.

## Fall Forward from Flash to html5 for iOS and Android Support

__Kaltura's HTML5 Video Library__ may be installed in conjunction with existing flash video integrations to provide fall forward from flash to html5 to enable video embedding for iPhone and iPad.

Installing html5 support to an existing Kaltura integration is as simple as adding a javascript tag to include `http://html5.kaltura.org/js`.  The library will automatically replace your Flash embed with an html5 `<video>` element on browsers capable of parsing the tag.

    <!DOCTYPE html>
    <html>
    <head>
      <title>Fall forward from Flash to html5</title>
      <script type="text/javascript" src="http://html5.kaltura.org/js"></script>
    </head>
    <body>
      <h2>Fall forward from Flash to html5</h2>
      <object id="kaltura_player" name="kaltura_player"
        type="application/x-shockwave-flash"
        allowFullScreen="true" allowNetworking="all"
        allowScriptAccess="always" height="330" width="400"

        <param name="allowFullScreen" value="true" />
        <param name="allowNetworking" value="all" />
        <param name="allowScriptAccess" value="always" />
        <param name="bgcolor" value="#000000" />
        <param name="flashVars" value="&" />
        <param name="movie" value="http://www.kaltura.com/index.php/kwidget/cache_st/1274763304/wid/_243342/uiconf_id/48501/entry_id/0_swup5zao" />
      </object>
    </body>
    </html>

## Themeing with jQuery-UI

You can add a custom jquery ui theme by using the theme wizard: [http://www.kaltura.org/apis/html5lib/kplayer-examples/Player_Themable.html](http://www.kaltura.org/apis/html5lib/kplayer-examples/Player_Themable.html). Note that although the themeroller only works in Firefox, the temes you create with it will work in multiple browsers.


## Skinning and Themeing

[Theme Wizard]: http://www.kaltura.org/apis/html5lib/kplayer-examples/Player_Themable.html

You can add a custom jquery ui theme by using the [Theme Wizard][].  Downloading that theme and adding a reference to jquery-ui-.custom.css after the mwEmbed-player-static.css file.

A few sample jquery ui skins are included in the skins/jquery.ui.themes folder of the [HTML5 Video Player][].

You can remove the kaltura attribution for the player by adding the following javascript:

    <script type="text/javascript">mw.setConfig('EmbedPlayer.kalturaAttribution', false );</script>

You can remove the kaltura attribution for the player by adding the following javascript: 

    <script type="text/javascript">mw.setConfig('EmbedPlayer.kalturaAttribution', false );</script>

### Notes on Optimization

mwEmbed is designed to be used with a script-loader and this static package sacrifices transport size and packages in code every client won't use, in order to be a single static file.  You can learn more about using mwEmbed with a script-loader on the project home page. 

To use the load optimized [HTML5 Media Library][] replace your mwEmbed script include line of `<head>` with:

    <script type="text/javascript" src="http://html5.kaltura.org/js" ></script>

For full un-minified source see [HTML5 Video Player][]

### Basic Usage

In the `<head>` of your page you will need jQuery and the mwEmbed-player package:

    <!-- If your page already includes jQuery you can skip this step -->
    <script type="text/javascript" src="kaltura-html5player-widget/jquery-1.4.2.min.js" ></scirpt>

    <!-- Include the css and javascript  -->
    <link rel="stylesheet" href="kaltura-html5player-widget/skins/jquery.ui.themes/jquery-ui-1.7.2.custom.css"></link> 
    <link rel="stylesheet" href="kaltura-html5player-widget/mwEmbed-player-static.css"></link> 
    <script type="text/javascript" src="kaltura-html5player-widget/mwEmbed-player-static.js"></scirpt>

Now in your HTML you can use the video tag and it will be given a user interface ie: 

    <video poster="myPoster.jpg" style="width:400px;height:300px" durationHint="32.2" >
      <source src="myH.264.mp4" />
      <source src="myOgg.ogg" />
    </video>
<h1 id="troubleshooting">Troubleshooting</h1>

<h2 id="codecs">Video Codecs</h2>

You will need to encode your video files into multiple codec formats to provide video for device platforms like iPhone, iPad, Android, and Blackberry.  [Dive into HTML5](http://diveintohtml5.org/video.html#firefogg) provides an excellent reference for encoding these multiple video formats with [Firefogg](http://firefogg.org/) , FFmpeg, and Handbrake.

If you would prefer to not have to deal with encoding your videos into multiple formats, you should obtain a trial account with [Kaltura](http://corp.kaltura.com/) and request a support technician setup your account to provide html5 flavored video codecs.

<h2 id="mime">HTML5 video MIME type</h2>

Note that if the MIME types for Theora video are not set on the server, the video may not show or show a gray box containing an X (if JavaScript is enabled).

You can fix this problem for the Apache Web Server by adding the extension used by Theora video files (".ogm", ".ogv", or ".ogg" are the common types) to the MIME type "video/ogg" via the "mime.types" file:

* Edit the mime.types apache configuration file (in "/etc/apache" on linux, "\xampp\apache\conf\mime.types" on windows-xampp)
* Search for `application/ogg     ogg` (if not exist skip this step), delete this line
* Add the following: `video/ogg     ogg ogm ogv`
* Restart apache

Or by adding the "AddType" configuration directive in httpd.conf - 

    AddType video/ogg .ogm
    AddType video/ogg .ogv
    AddType video/ogg .ogg
    AddType video/mp4 .mp4
    AddType video/webm .webm

Your web host may provide an easy interface to MIME type configuration changes for new technologies until a global update naturally occurs.
