[Player] does not show text description when turned on.

[allanj-uaag]

go to settings,
select text descriptions,
hit save,
turn on descriptions... the size of the player expands (grey area below the controls), making room for descriptions to appear
start video - no descriptions appear in the expanded area below the controls.
Note: If I turn on the transcript the descriptions are in the transcript.

hmm... if in settings I go to transcripts and enable "keyboard-enable transcript" then start the video with descriptions turned on the descriptions appear in the proper location.

Hi @allanj-uaag can you just give me your browser info, and see if the system exists in the development version at https://w3c.github.com/wai-showcase-examples/Overview.html

I think they appear too briefly in the non-AD version of the films. This is because there is not time for the descriptions to be vocalized. @allanj-uaag, please use the AD versions to view and hear the descriptions while we look into this issue.

[nitedog]

@allanj-uaag, I'm not finding a good way to provide the descriptions in the non-AD versions - either they appear too briefly, or screen reader users will potentially have overlapping sounds from the video and the descriptions. i've removed the descriptions from the non-AD version, which I think works best. Thoughts?

[allanj-uaag]

Took a fresh look at the videos. Most seems to be working fine.
Player settings
AD preferences

• text based description, read by screenreader
• make descriptions visible
  Transcript Preferences
• Highlight transcript as media plays
• Keyboard-enable transcript
  Keyboard Pref
• alt and control
  Caption Pref
• default
  In the Transcript window, 'auto scroll' is checked

I turn on caption, transcript, and audio description
captions work
audio description is spoken by the video announcer
audio description text is displayed below the controls
Transcript shows both the caption text and the audio description text. it highlights spoken phrases from the audio narration (not the audio description). Highlighting makes the first "jump" to new text when it reaches the bottom of the transcript window...new text scrolls into view. When highlighting reaches the bottom of the window new text scrolls into view and the highlighting tracks the words spoken, but the scroll seems to think it has 2 pointers, the last text from the first jump and all subsequent highlight start points. the highlight moves to new text and bounces up to last text on first jump, then down to current highlight, back up, down, up, then down to new phrase highlighted, up, down, etc to the end of the transcript.

Wow, that's an interesting effect in the interactive transcript. I haven't observed that before in Able Player. I downloaded the two WebVTT files for the audio-described version of your Keyboard Compatibility video and setup a simple test page using this HTML:

<video data-able-player id="video1" preload="auto" data-youtube-id="1rBwxGMT9ZM">
  <track kind="captions" src="keyboard_ad-en.vtt">
  <track kind="descriptions" src="keyboard_ad_desc-en.vtt">
</video>

This seems to work fine. The highlight tracks the caption text as expected, and skips the audio description text as expected (a known bug). It doesn't get stuck with the highlight jumping up and down like it does on your live site.

What other factors could there be to look into? Use of HTML/HTML5/ARIA? CSS? Other scripts/events?

[allanj-uaag]

This happened in windows 7, FF and Chrome. What other details/settings do
you want? Happy to provide them. This is a fabulous player!!!

I have updated the player, but I can still see the jumping or the autoscroll not working. And even if I switch off autoscroll, I can’t scroll as the container is scrolled back to the top all the time.

[RickyIR]

I notice when two transcripts are placed within the same page, the autoscroll causes the text to be jumping up and down when scrolling ( only occurs when there is more than one transcript on the page). I do not know the cause of this. Is it possible that Able Player cannot handle two autoscroll transcripts on one page, resulting in the autoscroll to be jumping? Thank you

[yatil]

This seems to work on the redesigned page (apart from the too large video player for the audio described version which I’ll note as a bug). Can anyone double-check?

@allanj-uaag @iamjolly Can you double check so this can be closed?
