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. Please try again or contact support. (Error co...

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

I'm experiencing this problem at my organization as well. Videos play fine in Chrome, and IE11 on Windows 10. Windows 7 IE11 will not play. I see the thumbnail for the video, but when I click on it the loading icon just spins forever with no error message.

I found this test website to test the Azure Media Player, https://ampdemo.azureedge.net/azuremediaplayer.html and when I visit that page in IE11/Win7 I get the following error "A network error caused the video download to fail part-way. Please check your network connection or try again later. (0x30200193)". There's also a verbose log it outputs that repeatedly says "warning: videojs: this.options() has been deprecated and will be moved to the constructor in 6.0" and then goes on to say "loading is failed for url https://amssamples.streaming.mediaservices.windows.net/91492735-c523-432b-ba01-faba6c2206a2/AzureMediaServicesPromo.ism/manifest"

I'm currently in an OU with absolutely no policy applied, I've done a factory reset on internet explorer, added all these sites to trusted sites, set security for the zone on the lowest possible setting, whitelisted my IP in the firewall and proxy, enabled SSL 2.0 and 3.0, disabled our antivirus, disabled pop-up blocker... not sure what else I can do. I've opened a case with Microsoft.

We are still experiencing this issue with Windows 7 and IE11. Current version of flash player is 31.0.0.135 and the plugin is enabled. When you click the video you briefly see it displayed for a second and then " The browser required Flash"error occurs. Is there any update on this issue?

  Jerry Ober As far as we were aware this was working with the latest version of Flash. Can you work with your O365 admin to open up a support ticket and get the needed logs/traces submitted via support?
  
  Saili Raje FYI, in case you know of something new going on with flash on Win7/IE11.

    Marc Mroz I opened a premium support ticket and will post the results as soon as I get them. This is happening on all of out Windows 7 pc's not just a few.
    
    Currently have Flash 31.0.0.135 installed and the plugin enabled.
    Also verified same issue with 31.0.0.122

I was able to get videos working in Windows 7 by modifying the following file
C:\Windows\SysWOW64\Macromed\Flash\mms.cfg

I added these entries to the file
EnableInsecureByteArrayShareableDomain=*.azureedge.net
EnableInsecureByteArrayShareableDomain=*.azure.net

I added the same entries to the this file as well, though it doesn't appear to be utilizing it since the browser isn't 64bit
C:\Windows\System32\Macromed\Flash\mms.cfg

Please keep in mind, this is opening up the vulnerability that was patched by Adobe (for this specific domain). Do this at your own risk.
