Stream Videos won't play on IE 11
I uploaded some videos last week and this week if we open the videos in IE11 we get the following error:
It looks like there’s a problem.

I'm so sorry for my severe lack of responses on the forums here. We've been super busy lately and I haven't had the time to respond properly. Sorry!
For this specific issue with playback not working Stream, O365 Video, or Skype Meeting Broadcast on Win7 + IE11, the issue is that Adobe made some changes in Flash v30, that broke the Azure Media Player for AES encrypted playback using ABR.
PROBLEM: The issue only happens in cases where our flash player is needed (IE11+Win7) and when your update to the latest version of Adobe Flash (v30).
We are feverishly trying to find a solution to work around the changes that were made in flash. We've tried many solutions so far but none of them have worked. Each time the fix ends up working some times but not others and we end up with timing or decoding errors. We are also reaching out to Adobe for questions/help as well.
Here are the only known workarounds we've found so far...
- Install Adobe Flash v 29
- Utilize a browser that supports MSE (Edge/Firefox/or chrome)
- Admin can select specific domains to allow the functionality that Flash 30 is blocking
- EnableInsecureByteArrayShareableDomain
- Short Description: Allows Administrators to override the Flash Player 30 and above default behavior of restricting the “shareable” property of the ActionScript ByteArray API class on a per-domain basis

MicrosoftHi there, is it possible you're loading your internal site in IE10 mode rather than edge mode? That would fall back to the flash tech.
I'd also like to notify you all that Stream has been actively working on a fix for this issue. We are in the process of deploying the fix to all DCs but playback won't work until Adobe fixes a bug in their Flash plugin. We've been working with them and the current timeline for Adobe's release looks to be early August.
Adding myself to the choir of complainers. We see this issue when we embed videos from O365 Video to Yammer. Just released our latest CEO video message and comment box under the video is full of complaints of video not working. Really rewarding.. It is really hard to understand and explain that how can't Microsoft's own platform work seamlessly with their own browser.

We apologize for the inconvenience. As Marc explained below Office video is in the process of deploying the fix which needs to be used in parallel with the updated version of Flash. The browser takes a dependency on the Adobe plugin and since there was a bug in the plugin that impacted playback we needed to work alongside them and their release cycle.

We are sorry for the problems this has caused everyone. This is an issue where Adobe Flash made a change that broke playback in Stream and O365 Video in Windows 7 + IE 11 + Flash v30.
It took lots of investigation, prototyping, and collaboration to fix this issue. The fix ended up needing 2 parts.
- Changes to the Stream and O365 video player
- Changes to Adobe Flash
- The beta release of Adobe flash has these changes currently: https://labs.adobe.com/technologies/flashruntimes/flashplayer/
- The official release of this will be in a patch update from Adobe slated for August 14th.
For Stream...
The updated player #1 above has been deployed to all of Production. So if you get the latest version of Flash that is slated for 8/14, the issue in Win7+IE11 should be fixed.
For O365 Video...
We are in the process of updated to the latest version of the player (#1 above) for both embed and the portal. The rollout of this fix will take another couple of weeks. And as in above with Stream you'll need the latest patched version of Flash that is due to come out 8/14.
The Microsoft support article on Stream actually made it very clear for Windows 7/IE11 and Flash version, https://docs.microsoft.com/en-us/stream/portal-understanding-playback-errors. I followed the suggestion upgrading from Flash 30.0.0.134 to 30.0.0.154, most of my company user problem is resolved. This is more acceptable to our service desk than a less robust beta version.
- I can confirm that updating a workstation with Flash version 30.0.0.154 corrected this problem on a Win7 + IE 11 machine that previously was getting video playback error in Stream here in our environment so this seems like good news.
