WAI-ARIA design pattern for media players

Terrill Thompson
I realize focus is shifting from WAI-ARIA Authoring Practices 1.0 to 1.1, but does anyone have an inside scoop on what happened to the "Media Player" design pattern in 1.0?  There's a block dedicated to this widget, but no content.

I'm almost positive their used to be something there, and I think I may have even consulted it frequently. Did I just dream that?

Thanks,
Terrill

I've been testing reading systems (in browsers and discrete) for TTS with EPUB using various affordances. None of the reading systems will instantiate either <video> or <audio>, despite the recommendation by WAI that only html5 semantic elements are used. The <button> tag is often called out but no control is afforded to the user. No doubt, this is why the media widget is empty of implementation language.

Terry,

The working group just has not got to that design pattern, we will eventually get to it.

What ARIA features does AblePlayer use?

Re: WAI-ARIA design pattern for media players

Sorry for the slow reply, Jon. I finally rediscovered the resource we used when building in support for particular keystrokes for controlling Able Player. It was the DHTML Style Guide:
http://access.aol.com/dhtml-style-guide-working-group/#mediaplayer

There's not a lot there, and I realize it's been superseded by more recent W3C work, but it was current at the time so we implemented all of the recommended keyboard shortcuts:

    Control + Alt + P = Pause/Play toggle
    Control + Alt + S = Stop the player (May not be needed if Alt + P performs the same functionality.)
    Control + Alt + M = Mute
    Control + Alt + U = Volume Up
    Control + Alt + D = Volume Down
    Control + Alt 1 – 5 = Change the volume. 1 being the lowest volume and 5 being the loudest.
    Control + Alt + C Captions toggle.

Since the recommendation called for using Control + Alt as modifier keys, we're using those by default but users can easily change them in the Keyboard preferences dialog.

You asked about ARIA - that's a much larger topic. I'll see if I can carve out some time to contribute to the WAI-ARIA Authoring Practices 1.1 discussions via the official channels.

Regards,
Terrill
