Acknowledgment to Country

On behalf of all present, I would like to acknowledge and pay respects to the original custodians of this country we are meeting on today, the Wurundjeri peoples. I pay my personal respects to the existing family members of the Wurundjeri. I also pay respects to Elders past and present.

But aren’t there other options?

This player was designed to…

• Work on HTML5 based web browsers (not mobile)• Be easy to add to a web page• Use no JavaScript to set up the player• Use a common JavaScript library for support (jQuery)• Have an easy to update design (CSS not JavaScript)• Use available ARIA attributes• Comply with WCAG2. AA where technically possible

The player is quite accessible

• Screen reader accessible• Keyboard accessible (fullscreen and not)• No keyboard trap • Subtitles• Audio description track• Subtitles can be changed in many ways – Font, colour,

size, opacity, position.• Updated feedback on some browsers, Firefox reports

ARIA information better than other browsers.

   <audio controls="controls">      <source src="video/345-ad.ogg" type="audio/ogg">      <source src="video/345-ad.mp3" type="audio/mpeg">      Your browser does not support the audio element.   </audio></div>

Conclusion

• HTML5 is set to become the standard in 2014 making it easier to embed video

• There should be one video format that is accepted by all browsers

• The track tag should and is being made available• Flash fall-back will be necessary due to MS support for

XP. IE8 doesn’t support the video tag and IE9 won’t install on XP.

• Saving subtitles straight to WebVTT format should be much easier

• Google are doing a lot of work with subtitles in YouTube
