Playback issues in Edge browser after installing Windows 10 Creators Update 2019-01-16T15:30:37+00:00

Knowledge Base Supplier: June, 6, 2017


After installing the Windows 10 Creators Update, Edge browser does not play Mediasite content where Flash is required.


Microsoft is restricting Flash in the Creators update. When Edge blocks Flash content it should display a warning with the option to “Allow once” or “Always allow” Flash on the current site. If you wish to override this behavior navigate to Menu > Settings > View Advanced Settings. Toggle “Use Adobe Flash Player” from Off to On.

Download recording 2019-01-17T14:45:24+00:00

Collegerama records lectures with a double video stream; which makes a fairly strong internet connection essential. We are not recording on high resolutions but already our stream is significant. Lowering resolutions to enable smooth playback on poor wifi is no option for us; slides would become unreadable as well as handwriting on black/whiteboards.

Apart from the above, we service the TU Delft by making Collegerama recordings. We do not have copyright on these recordings therefore we can not make downloads available. Lastly, it is simply not possible to make a download with both video streams in one video. So we would have to make a choice: lecturer or slides?

HTTPS security 2019-01-17T14:45:07+00:00

Collegerama uses https encryption for security reasons. The regular content is not https enabled, but the part where you login as student/employee is. Your net-id and password are not visible to outsiders.

I have a problem with login Collegerama 2019-01-17T14:48:24+00:00

First check before contact:

  • You are able to login to Brightspace?

Collegerama is connected via SurfConext (which is the gateway to all TU Delft platforms). Collegerama only checks your netid on the authentication server. If you can login to your webmail, you should also be able to login to Collegerama.

In the past six months we have run a pilot to integrate Whatsapp into our website with an external supplier. Because certain functions have not yet been implemented and due to the high costs per message received, we will terminate our contract for the moment. As soon as the function(s) that we want to use are added, we will reconsider whether we will extend our contract again.
