Kaltura - Accessibility

Last Updated: 06/16/2017

What is Accessibility?

‘Accessible’ means a person with a disability is afforded the opportunity to acquire the same information, engage in the same interactions, and enjoy the same services as a person without a disability in an equally effective and equally inclusive manner, with substantially equivalent ease of use.

Information for Content Creators

On July 4th, 2015, the default Kaltura player in Desire2Learn and Kaltura MediaSpace will be updated to an accessible HTML 5 player. 

Content creators should keep the following information in mind:

  • While you can upload video files directly into D2L, we recommend that you upload video to Kaltura via the Contribute Media widget. This will ensure that the media will be played using an accessible HTML 5 player.
  • The videos you provide should be captioned. OIT can assist you with captioning your media. To begin the process, complete the Captioning Request Form.
  • Audio files should either be:
    • converted to video (e.g. with a simple background image) so they can be captioned, or
    • accompanied by a PDF transcript.
  • Add audio description tracks to the videos uploaded to make them accessible to people who are blind or visually impaired.
  • If there is a pedagogical or business reason videos with flashing or blinking content are needed, provide a warning to users.

Additional resources for producing accessible media will be provided via the Accessibility Technology website.

Information for Content Consumers

When accessing videos in Desire2Learn or in Kaltura’s MediaSpace:

  • Remember to enable closed captioning and/or audio descriptions on video content when available.
  • Note that the videos display in accessible HTML 5 Players when accessed via iOS and Android devices.
  • The default Kaltura player can’t be viewed in full screen when using Internet Explorer. As such, we recommend that you use other browsers. We are working with D2L to resolve this issue.
  • In order to ensure that assistive technologies can detect videos, users must adjust the Video Settings in their Account Settings in Desire2Learn. Under Video Settings, tick “Optimize video presentation for programmatically-driven assistive technologies.” As a consequence, videos will overlap menus. The accessibility of specific players will not be impacted.

The following are known issues that affect those using screen reader technology:

  • Testing has indicated that there are issues with using Windows Eyes in combination with Firefox to play Kaltura videos. Windows Eyes users should try using Internet Explorer instead when interacting with Kaltura videos.
  • VoiceOver for iOS 8.4 or lower does not recognize the iframe containing the Kaltura video controls, so there is no way to access the video using standard navigation. VoiceOver users should access Kaltura videos on a Mac or another device rather than an Apple mobile device.
  • VoiceOver for Mac does not correctly read certain labels for Kaltura video controls. However, the video controls can still be operated.

Service Road Map

We will be reviewing the Kaltura application as a part of our planned accessibility audit. Once this audit is complete, we will update the accessibility considerations outlined on this page.
