As referenced in this question (https://www.outsystems.com/forums/discussion/48607/how-can-i-show-the-video-on-the-web-app-from-database/) I am displaying a video from a database using the WebPatterns>Controls>Video player from OutSystems UI.

In fact I downloaded the oml file in the solution from Eduaro Jauch to test here:
https://midlandheart-dev.outsystemsenterprise.com/VideoTest/Entry1.aspx?_ts=636959485518194133

If you view this in Chrome it displays correctly:

But if you look in IE11 it cannot display the video with the error "Unsupported video type or invalid file path:

Note that we only started seeing this behaviour in our apps after upgrading the platform from 10 to 11, so anyone got any ideas?

Hi, 

In my computer (:D) it works both in IE11 and EDGE.

Did you try this? https://stackoverflow.com/questions/38231206/ms-edge-and-ie-11-does-not-support-html5-video-element

They recommend installing some sort of video codec pack on windows to be able to use HTML5 video tag on IE11...

Probably my computer already has this installed :)

Cheers.

Russel, 

I just tested YOUR version, and your version of the app does not work... :/
Did you make any change to the code I posted?

Try this one: https://jauch.outsystemscloud.com/VideoTest/Entry1.aspx?_ts=636959514531937728

Also, you could check if you have the latest OutSystemsUI version installed?
