Hello,
My name is Gitesh,

I'm currently developping a website to stream video's in Asp .Net 5(c#).
Azure Media Services is my chosen platform to host the video's from.
Azure Media Player is the player I use on the website to render the video's.

I have got the playback of unprotected videos running, but I'm struggeling to get the playback of a DRM encoded video running. Via the Azure Media Services Explorer tool I have configured DRM on one particular asset.

When I playback the video via the Azure Media Services Explorer tool with the Azure Media Player, Its working fine with Bearer token.But when I try to playback the video from my website(I am sending Bearer Token as authToken on FrontEnd.), it is diplaying "Unable to decrypt the encrypted video source (0x20500006)". I see in chrome developer tools (console window) then getting below error.
Failed to load resource: the server responded with a status of 401 (Unauthorized).

Azure Media Services
Azure Media Services
A group of Azure services that includes encoding, format conversion, on-demand streaming, content protection, and live streaming services.

    Can you share an auth token you used as bearer token by your player (outside of AMSE)? Which service issued the token?

    AMSE issues symmetric token with a static encryption key, while most token issuers issue tokens with asymmetric key. Let's start from the token issued and token claims.

    Hi Sanjay,

    Sorry for the late response

    I have resolved the above issue by using the below code. Below code is working for both (Window and MAC)

    <video id="resourceVideoTag"
    class="azuremediaplayer amp-default-skin amp-big-play-centered video-upload-box vid2"
    controls
    width="640"
    height="400"
    poster="@默 .ResourceVideo.ThumbNailUrl"
    data-setup='{
    "controls": true, "autoplay": false ,
    "logo": { "enabled": false },
    "techOrder": ["azureHtml5JS", "flashSS", "html5FairPlayHLS","silverlightSS", "html5"],
    "nativeControlsForTouch": false
    }'
    tabindex="0">
    <source src="@默 .ResourceVideo.VideoUrl"
    data-setup='{
    "protectionInfo": [{"type": "PlayReady", "authenticationToken": "@默 .ResourceVideo.BearerToken"},
    {"type": "Widevine", "authenticationToken": "@默 .ResourceVideo.BearerToken"},
    {"type":"FairPlay","certificateUrl" :"@默 .CertificateFilePath","authenticationToken": "@默 .ResourceVideo.BearerTokenFairPlay"}] ,
    "techOrder": ["azureHtml5JS", "flashSS", "html5FairPlayHLS","silverlightSS", "html5"]
    }'
    type="application/vnd.ms-sstr+xml" />
    <p class="amp-no-js">
    To view this video please enable JavaScript, and consider upgrading to a web browser that supports HTML5 video
    </p>
    </video>

    Jquery Code

    var myResourcePlayer = amp('resourceVideoTag');
    amp('resourceVideoTag').ready(function () {
    myResourcePlayer = this;
    myResourcePlayer.play();
    });
