capagrisdesu Thanks for reaching out, and welcome to the MS Edge Insider's community! If you haven't yet, can you please submit detailed feedback and diagnostic data through the browser?

 

And in the meantime: josh_bodner, does this seem related to the issue you found with playing protected PlayReady content?

    Deleted josh_bodner  I have done a bit more of research. I have found that the crash happens because of distinctiveIdentifier is set to required, then requestMediaKeySystemAccess will crash. If it is set to "optional", it will do playback. Please fix this (and check why the Microsoft test stream is not supported).

     

    navigator.requestMediaKeySystemAccess(systemString, configs)
    "com.microsoft.playready"
    [{
    Array(1)
    0: KeySystemConfiguration
    distinctiveIdentifier: "required"
    initDataTypes: ["cenc"]
    persistentState: "optional"
    sessionTypes: ["temporary"]
    videoCapabilities: [{
    contentType: "video/mp4;codecs="avc1.64001F""
    robustness: ""
    }]
    }]

     

    Thanks

      capagrisdesu Thank you for doing that investigative work! I'll check-in with the team about this.

        Deleted are there any other known issues with PlayReady right now?

    Deleted I'd be curious how this performs in our current Canary or Dev builds.  The current Stable branch is getting a little long in the tooth, and although it's due to be updated soon, testing in one of our Insider branches is the best way to help narrow this down.

      josh_bodner I have tested in both Stable and Canary. Definitely Canary gave me less crashes but still does not work as well with Dash.js as former Edge did.

       

      Deleted Please be more specific about any data and steps I should do to provide further information.

       

      There is something very simple that you can do to see what I believe is another issue with Chromium Edge using Microsoft PlayReady test streams!

       

      Dash server http://reference.dashif.org/dash.js/v3.0.1/samples/dash-if-reference-player/index.html

      Dash stream http://profficialsite.origin.mediaservices.windows.net/c51358ea-9a5e-4322-8951-897d640fdfd7/tearsofsteel_4k.ism/manifest(format=mpd-time-csf)

      Old Edge 44.17763.831.0 -> Works

      Canary 83.0.477.0 -> Does not work
