Re: [orca-list] Media Goblin Audio Player Not Very Accessible

[Janina Sajka <janina rednote net>]

Sliders are among the widgets covered by ARIA. And, you can certainly
expect a media player with have controls like Play/Pause/Stop, Fast
Forward, Rewind, etc.

A good starting point for ARIA markup is the WAI-ARIA Authoring
Practices Guide (APG):
http://www.w3.org/TR/wai-aria-practices/

Please note that HTML 5 also provides an API for access to media
controls as well as full support for all manner of alternative content
such as descriptions and captions. In fact HTML provides support for
semantic content navigation, not just a time-offset forward and reverse.

The relevant section of the latest version of the HTML 5.1 specification
is Sec. 4.7.14:

https://www.w3.org/TR/html51/semantics-embedded-content.html#the-media-elements

I would argue that any player not using HTML 5 will soon be overcome by
events. As supporting APIs emerge from W3C, they will quickly become
obsolete.

Example of what W3C APIs will enable: Send the video and audio to the
big screen with the Atmos speakers, but send the video description to my
Bluetooth headphones.

Just my two cents (American).
