Audio playing at high speed after resuming HTML5 content in Safari on iPad mini

Apr 28, 2015

The audio in question sounds like one of the chipmunks from the old cartoon. :) Has anyone else seen this behavior?

I would go ahead and search on it and see what you find.

The video issue I had is this:

1. If you have audio tracks on the same layer as your video there is potential for overlap, especially when scrubbing the Seekbar. I found when you scrub through a slide it doesn't match up with the video playback.

(we had narration followed by video followed by more narration - scrubbing the video took it out of sync with the timeline playback and both ended up playing at the same time) Happened on both iOS and Android systems.

2. On iOS, videos pop up in their own player and are independent of the Articulate timeline. You can launch a video, stop it and select done, and the Articulate timeline keeps playing the track like it thinks its still running. This also led to media overlap. Wasn't sure how to tackle that. We ended up placing ALL videos by themselves without any other media on the layer.

One other thing I noticed - not sure if it happened to you or not - the Articulate player "Play" button on their interface disappeared in the HTML 5 output.

More - If you are using transcripts and have any that are long - be aware that the slider bar sometimes covers up text. Seems to be a programmer issue, they didn't account for the extra space taken up by the slide bar so it hides parts of the text lines beneath it.

Thanks very much for this info, I'll forward it to our testers.

I didn't notice any issues with the video playing, but I don't think we trying scrubbing the seekbar.

I believe the audio is on a separate slide from the video, so hopefully that will eliminate some potential issues.

We are not authoring the course, only testing, so I don't have access to the .story file to look into how this was built. I appreciate your help!

No problem - we just went through multiple rounds of testing and discovered a lot. Most of the reviewer issues were related to the audio playback.

Yea - make sure you scrub that Seekbar during testing. Especially if you note that there is narration before and after videos. Here's my full set of notes recently provided to our client:

Program items noted:

- Seekbar (when scrubbed or clicked into position) gets out of sync with video content

- Seekbar occasionally fails to display on Replay; selecting the Play button makes it show up

- Transcript notes display differently than what is formatted (Single hard returns ignored)

- Transcript text gets cut off (slightly hidden) when scroll bar shows (programming didn't account for scroll bar graphic)

- "Play" button failed to display on some Android systems

- Video set in base layer on timeline caused overlapping content (audio) issues on iOS systems

- Video on mobile, iOS systems displays in its own player

- Seek bar continues to play after you stop and close video on iOS (it continues to run the length of the video track)

- Video on Android plays normally

- Player Tabs hard to access on mobile phones

- Graphics overlapping buttons can interfere with selection (Hot) area

- SCORMFunctions.js file needs replaced for output to SABA LMS

- Tabbing does not work in HTML 5 output

- Player navigation buttons hard to select on phone systems

- Layer "Rename" option works a little kludgy

- No built in slide numbering

- No reset for Drag & Drop items

Thanks so much for typing that up. This is a great list and will be a fantastic reference for me going forward with my own projects.

I believe this is one of the reasons Adobe developed Flash in the first place, to ensure a consistent user experience. It's too bad they didn't keep it lean and mean, forcing Apple to look elsewhere to maintain battery life, I believe.
