Getting This privilege requires Partner level signing key. For drminfo priviledge

New to Tizen and writing apps for TV. Trying to learn how to work with a DRM's. Do I need to go through getting to be a partner to use this sample?

Thanks,

Working example with Widevine Modular

Hi!

We are having some issues with the integration of Widevine Modular DRM using avplay.
Followed the example from this page: DRM Contents Playback Sequence, but even with the testing streams from Shaka demo samples we are getting "Invalid license challenge" 500 errors from the license servers. Same content works with Shaka player. There is some difference in how EME in the browser constructs the Challenge body and how avplay does it in "ondrmevent" callback, but it's hard to understand since it's base64 encoded (even after decoding it's still not readable).

Please provide working updated example of Widevine Modular integration.

Sample Dash Manifest URL: https://storage.googleapis.com/shaka-demo-assets/angel-one-widevine/dash.mpd
Sample Widevine License URL: https://cwip-shaka-proxy.appspot.com/no_auth
No custom headers needed, everything works with Shaka on this combination.

Brief example of how we do it in the code:

// Before prepareAsync
        drmParam.AppSession = uniqueId(); // random number
        drmParam.DataType = 'MPEG-DASH';

        if (parseInt(platformVersion, 10) >= 5) { // const {platformVersion} = tizen.systeminfo.getCapabilities();
          const STRINGIFIED_PARAMS = JSON.stringify(drmParam);

          webapis.avplay.setDrm(DRM_WIDEVINE, 'SetProperties', STRINGIFIED_PARAMS);
        } else {
          webapis.avplay.setDrm(DRM_WIDEVINE, 'Initialize', '');
          webapis.avplay.setDrm(DRM_WIDEVINE, 'widevine_app_session', drmParam.AppSession);
          webapis.avplay.setDrm(DRM_WIDEVINE, 'widevine_data_type', drmParam.DataType);
        }

// inside ondrmevent callback
            const decodedMessage = atob(drmData.challenge);

            const drmChallengeRequest = new XMLHttpRequest();

            drmChallengeRequest.responseType = 'arraybuffer';
            drmChallengeRequest.open('POST', this.licenseUrl, true);

            drmChallengeRequest.onload = function() {
              if (this.status === 200 && this.response) {
                const licenseParam = `${drmData.session_id}PARAM_START_POSITION${btoa(this.response)}PARAM_START_POSITION`;

                webapis.avplay.setDrm(DRM_WIDEVINE, 'widevine_license_data', licenseParam);
              } else {
                console.log('Error in license request');
              }
            };
            
            drmChallengeRequest.send(decodedMessage);

Here is the Diff of how Shaka player constructs license challenge request body, and how Tizen native player does that. First of all Tizen player doesn't detect TV model properly, and then there is a difference at the bottom of the request, but since it's unique at each request and encoded, it's impossible to understand which part of it is incorrect:

how to implement verimatrix drm

how to implement verimatrix drm ?

I use these code:
var url = 'https://s3-us-west-1.amazonaws.com/integration-support/public_content/content_a/content_a.m3u8';
var host = 'ott-integration-1.verimatrix.com';
webapis.avplay.open(url);
var drmParam = new Object();
drmParam.CompanyName = CompanyName;
drmParam.IPTV = '';
drmParam.Web = host; //HOST IP
webapis.avplay.setDrm('VERIMATRIX', 'Initialize', JSON.stringify(drmParam));
webapis.avplay.prepareAsync(function(){webapis.avplay.play();});

and I got an error, drmEvent = "VERIMATRIX", drmData = Object {code: "4", message: "Createhandle/getrights/drmwebset/parserurl error", name: "DrmError"}

what does this error mean? how to modify my code to support verimatrix drm?

Can not play with drmtoday licences

No verimatrix example

This repo is refered by this page

Where we can find the verimatrix example?

Thx in advance
