Persistent licenses on windows edge

[learnyst]

Environment

• The MPD passes the DASH-IF Conformance Tool on https://conformance.dashif.org/
• The stream has correct Access-Control-Allow-Origin headers (CORS)
• There are no network errors such as 404s in the browser console when trying to play the stream
• The issue observed is not mentioned on https://github.com/Dash-Industry-Forum/dash.js/wiki/FAQ
• The issue occurs in the latest reference client on http://reference.dashif.org/dash.js/ and not just on my page

• Link to playable MPD file: Reference player
• Dash.js version: Latest reference player
• Browser name/version: microsoft edge
• OS name/version:windows

Steps to reproduce

1. Please provide clear steps to reproduce your problem
   I am testing persistent licenses on microsoft egde browser. As per No support of persistency on Edge #2658 Edge licenses persistence #2714 persistence licenses are supported on edge. In dashjs reference player (https://reference.dashif.org/dash.js/v3.0.1/samples/dash-if-reference-player/index.html) there is a content for microsoft edge persistent licenses. But this never plays and always gves error

2. If the bug is intermittent, give a rough frequency if possible

Observed behaviour

In reference player microsoft edge persistent content not played.

Console output

NA

In fact, it is just a problem of Mixed-Content security issue in the sample. If you test the reference player page in https and the licenser url is in http, then Edge complains there is a security issue.

If you test it from http://reference.dashif.org/dash.js/v3.0.1/samples/dash-if-reference-player/index.html it should work.

We are going to provide a PR to make the licenser url in protocol-relative form to work either in http or https

see #3163 (https for serverURL is fine for both http and https test page, so no need to use protocol-relative //)

Hi,

I have tested by changing the protocol.

Step-1: Open dash reference player from https://reference.dashif.org/dash.js/v3.0.1/samples/dash-if-reference-player/index.html
Step-2: Change stream to https://profficialsite.origin.mediaservices.windows.net/c51358ea-9a5e-4322-8951-897d640fdfd7/tearsofsteel_4k.ism/manifest(format=mpd-time-csf)
Step-3: Click 'ShowOptions'. Change DRM key system to playready. Set License Url to https://test.playready.microsoft.com/service/rightsmanager.asmx?cfg=(**persist:false**,sl:150)
Step-4: Play the content. The content plays successfully and I can see the license request with persist:false (In network messages)
Step-5: Change License URL to https://test.playready.microsoft.com/service/rightsmanager.asmx?cfg=(**persist:true**,sl:150)
Step-6: Play the content. the content plays successfully and I can see the license request with persist:true (In network messages)
Step-7: Pause the play. And Load the content again(By pressing load button). Content plays successfully. But it is not using persistent license. I can see the license request message again with persist:true.. Play any number of times. Every time license request is sent with persist:true.

I have tested on:
a. Windows 10
b. Microsoft Edge 44.18362.449.0

So the persistent license is not working on windows-10 microsoft edge. Please help us in fixing this issue.
