Captivate HTML5 output with video stalls with IE11

Report · Aug 24, 2015

Hello

I have a HTML5 course output with slides and video from Captivate 8 that work perfectly with Chrome however with IE11 it stalls with a permanent IE11 "loading" screen:

The strange fact is that the video in the course plays fine, but the captivate course slides container and contents don't work and stalls.

In fact it plays fine until any action or click on the slide is called or used, even the standard playbar buttons.

The video is in .mp4 and 35 mins / 240 Mb long.

The behaviour appears both from localhost and web server access. However it does not happen if opening directly the published index.html file locally.

I would like to add this behaviour happens even when opening a new project a placing a synchronised video on a slide adding a simple button with an action.

Much appreciate any help.

Has anybody solved this?

Does Captivate 9 support IE11 and HTML5?

Report · Feb 29, 2016

It normally does. Have you tried creating a very simple one slide project with no objects, publishing that to HTML5 and uploading that output to the same server? Does it work then? If so, then your issue would be with something on one of your slides in your current project. If if doesn't, then the issue is with something about the standard Captivate output code.

We are having the same issue, here is some output if anyone has ideas. We have output to HTML5 and are hosting on IIS server with an in-house .Net solution for the LMS.

We are currently suffering from this HTML5 issue as well in IE11, this happens randomly on Win7 and on almost every video page on Win10.

What we see - The page loads up and plays the video for a few seconds, then the loading icon appears. The video continues in the background whilst the timeline is paused (so any graphics that have been overlayed don't appear). Once the video has finished, the loading icon disappears and all the timeline graphics rush through to as they should be at the end of the Captivate timeline.

Video of issue:

Captivate loading issue

We have tried both CP9 and CP2017 (both same issue). We are loading the videos as "progressive" and have tried the video on one slide or across multiple slides. Interestingly Event videos work fine in IE11, but these are no use as we need the timeline synced and to have controls available from the course navigation.

We have also replicated the issue using a blank file with different videos, so this appears not to be an isolated issue with the file. It seems to be a problem between IE11 and Captivate (as no issue with many other browsers and mobile devices).

We have spent many hours trying to resolve this and are running out of ideas, so any help would be greatly appreciated.

I managed to solve this issue as follows:

- Internet Options > Advanced > Accelerated Graphics

- Activate the option "Use software rendering instead of GPU rendering"

- Restart IE

Thank you for the reply. I have tried your solution using a Win10 Laptop with IE11. Unfortunately after selecting that option, restarting computer and testing... the problem still occurs.

Something else we tried with mixed results, was to back the video off the start of the timeline, so instead of starting at 0 sec it was maybe 1sec (giving it a bit of buffering time). This almost eradicated the issue for us, but the client could still see it (yes they were clearing caches, trying different machines and trying different networks).

Adobes solution was to re-encode the videos to a higher bitrate than we had previously (without much explanation as to why). Previously our videos were encoded in Media Encoder to 0.5Mbps (min and max), but we were told to change it to 2Mbps (min and max). This almost tripled our video files sizes, and for some unknown reason (like with backing the video off the start of the timeline), this almost eradicated the issue for us, but again, the client could still break the course consistently.

In the end, our solution was extreme. We rebuilt the whole project using Storyline 360 and are having no video issues. As a bonus, it also addressed a separate issue where Iphones popout video from the course, Storyline have implemented a fix for this which I think Captivate should take note of.

According to your Errors:

error code = 4 n/w state = 3

Error code 4 means audio/video not supported

n/w state 3 means no audio/video source found

It could be something with the codec. Those are definitely errors returned from the video object, Captivate is just reporting them.

I've been experiencing this same issue. While my video is running, I see the gray loading screen, and all controls are disabled. Through some thorough debugging, I've been able to identify that this is built in to Captivate Captivate has a div call blockUserInteraction that gets enabled anytime it thinks the video is buffering. When this div is enabled, it blocks all other interactions. I've found that I can hide this interaction so that it doesn't make the screen gray by adding some javascript to the slide when it starts: {$('.loadingBackground').css({'background-color':'#fff', 'opacity':'0'});} but it still blocks any interaction with the slide. I've also tried deleting the div, which caused other issues, and moving the div off of the slide. Moving the div off of the slide seems to work. I could now access the buttons on the slide, and the skin buttons. I can see the button states change, but clicking the buttons was unresponsive.

I'm hoping this information will help someone shine the light on where the problem in Captivate is, so we can find a fix.

We have also tried all the things that you have mentioned and came across the same further issues.

It would be good if Adobe looked into fixing issues with Captivate, but they rarely do. This issue is still apparent in Captivate 2019.

We would like to continue using Captivate, but this video issue is making us pick up Storyline more frequently now.

Have you logged the bug with Adobe?

Yup, and the team has spoken to them over the phone.

But still no solution, I take it?

Afraid so.

Try executing this script on enter of the slide with the video

setInterval(function(){cp.Movie.prototype.unblockUI();},1000);

Thank you for the input TLC. Unfortunately the loading issue still appears for us when trying your solution.
