Video Buffering Endlessly

Aug 31, 2017


I am facing a problem with video slides in my module. I am testing a storyline course (HTML version) on an LMS. The videos are playing okay but when I scrub the seekbar back after the video reaches the end of the timeline and then hit the play button, the video never loads and keeps on buffering endlessly.

Has anyone ever faced a similar problem? Any solutions?

Thank You!

Hi Alyssa,

Thanks for the quick response! ☺️

Yes, the video is an embedded '.mp4' file. This is happening specifically in Firefox. The course plays fine in IE and although there are some syncing issues in Chrome, the scrubbing back thing from the end of the timeline and endless buffering of the video is happening only in Firefox.

Hi Varun, 

I put together a quick test file here, and I'm seeing the same thing you're seeing in Firefox. I really appreciate you bringing this up, and I'll be sure to report it to my team. In the meantime, can you use the seekbar rewind button instead of scrubbing the seekbar?

Thanks again for letting us know what's going on, and I'm sorry if it's slowing you down!

Hi Varun,

Yes, this is a bug that I reported to my team. I'll post an update here if I get any new information about it!

By the way, we may be calling the same button by two different names. This is the button you're referring to, correct?

We call that the rewind button, but the name "replay button" also makes sense. ☺️

So when inserting an MP4 into a slide and it is going to be the only thing on the slide when we want the video to "show until end"? That seems to be the default when inserted, but I wonder how this effects the ability to seek and jump around in the video using the Player Seekbar?
