Video not playing once project is published...

Hello Ant,

Downloaded the story and previewed, video played fine.  Published and the video still played fine, so I'm not able to replicate the issue there.

Are you having problems after the video is uploaded to a server?  If so, then you are more than likely running into a mime-type issue: http://www.articulate.com/support/kb_article.php?product=st1&id=w9bvqxxido6t

When we first transitioned to using mp4 video we had to have it enabled on all of our servers before the video would work.  If you have a site through a website host, there will normally be a control panel where you can enable these settings, or you may need to contact your web hosts customer support.

Hi Brian - thanks for that, I'll look into your suggestion.

Assuming I need my LMS adjusting (which I may not have access too right away, can I use a different video format to overcome this issue?

unfortunately no because all storyline videos are converted to MP4s

I believe that if you insert your video as a FLV, then Storyline will not convert it to mp4, but I'm not 100% sure on that.

The language in this video tutorial makes me believe that's the way it works: http://community.articulate.com/tutorials/products/adding-videos.aspx

It states: "Storyline supports numerous video file formats.  SWF, FLV, and MP4 are natively supported.  Other video file formats will be automatically converted to MP4 when you insert them into Storyline."

It would be great though if someone else could chip in here and confirm one way or another...

Looks like we were posting at the same time Phil - thanks for confirming!

ok thanks guys!

Worth trying FLV, may not get converted

Phil, I think you're right...  It seems like I tried this when SL was in beta and the FLV was converted to mp4, but I just can't remember for sure.  I'm going to have to try it here once I get a few minutes

The weird thing is, I have other projects where the videos play fine?! So maybe it isn't the LMS settings issue...

That is strange - is it possible that the other videos aren't mp4? 

I know that when we first starting using the mp4 format we had to add the mime type to our LMS servers.  That, plus the fact that your story played fine for me when I published it made me believe that it was probably a mime type issue, but it's possible that it could be something else.

Hi guys,

Just to add to this thread, I have worked out that it cannot be anything to do with the server settings and MIME etc., because the video is playing in the Preview but isn't playing once the project is published and I open the HTML file stored locally on my machine.

So this is before it has been uploaded to the server..

I have another thread with another issue that my backgrounds are disappearing when I publish the project (http://community.articulate.com/forums/p/17859/100760.aspx#100760), so I'm thinking that maybe there's something I've done with my computer that is causing these issues.... this has never happened before.

So if anyone else has any ideas, please let me know

Brian advices worked for me! My video started to play! All trouble was in mime.

Ant,

Did you try a different browser?  If you're using Chrome, some folks have been experiencing what you're describing when using Chrome.  IE9 seems to clear it up.

Hi guys - as Mike just said, the issue was rectified by changing browser (thanks Mike). I've never had an issue with Chrome before, but they must have made some updates to Chrome that is messing with Storyline.

I will submit a bug report... thanks for all the help! Got there in the end!

Ant,

Near as I can figure, it has to do with the built-in flash player in Chrome.  The Adobe forums have had some buzz about it lately.  I'm guessing it's not a Storyline bug, but more a bug on either Adobe or Google's part.  I have had some luck disabling the latest version of the plug-in in Chrome and getting SL output to play normally.

Hello

Appreciate this is a very old post, but we came upon this problem recently as well. Our customer was using a number of different LMS's and some uers could see and hear the video, whilst others just saw a  blank screen with no audio. The 'non-video' Storyline screens in the module worked just fine, however. We tried the Mime route and everything else that was recommended, but to no avail.

It seems, however, that we have fixed the problem.Strange as it seems, it is possibly something to do with the length of the pathway to the Storyline files. If we mapped a drive rather than use the UNC for the server AND maybe reduced the length (or number) of folder names in the path, it all worked fine. We could reproduce this problem and solution on a number of our machines and it seems to have sorted the problem for our customer, too.

Credit where credit is due, I have to thank my colleague Barry Stoner for his work on this problem!

Hi Martin,

Thanks for sharing that here - and linking to a file with a path close to or over 260 characters is known to cause problems as indicated here, and this is actually a limit imposed by Microsoft. 

You'll also want to ensure you haven't used any special characters, symbols, etc. as mentioned in that article within your file name or path and that you work with local project files.
