Audio description #12

Closed mkra closed 12 years ago

mkra commented 12 years ago

Is audio description available for jMediaelement or at least planned for a futur release?

aFarkas commented 12 years ago

Yes, it is supported through the data-role="textaudiodesc" attribute. Here is an example:

<a class="track" href="srtfile.srt" data-enabled="enabled" data-role="textaudiodesc">My audio description</a>

If you are using this markup. You won't see anything, but the file is automatically fetched and WAI-ARIA is used to directly output the text to a screenreader.

Note: I'm currently building JME2, which will change a lot. And will also support building audiodescription using the track element or the mediagroup attribute.

First release is planned for december/january, but won't have neither fullscreen, track, playlist nor mediagroup support. Those "extra" features will be added step by step... But it will be very nice.

Thanks for the quick answer. Is it possible to add an audio as audio description? I fear not all Browsers support the textaudiodesc role.

aFarkas commented 12 years ago

The data-role="textaudiodesc" is a custom attribute, which tells JME to create a WAI-ARIA liveregion wrapper for the track content. Live region support can be considered as good. IE8+, FF3+ and Safari4+ do support it and Jaws 10+, Windows Eyes 5.5, NVDA etc. do also support it on th AT site.

If you want to connect an audio with a video this is also possible. I have written an unofficial plugin for this. I can get the code on monday, but I can't add a lot of doumentation.

I have to support IE6 and IE7 as well, so i'll take a look at your plugin if i get the code.
