FairPlay problem

Hello,

I am not sure about the first error.

For the second error, in order to use FairPlay with CMAF (or to enable offline FairPlay too), you need to create and use a custom streaming policy. In that policy, you need to activate FairPlay with DASH (as CMAF used MP4 fragments). The CommonEncryptionCenc and CommonEncryptionCbcs objects can be created as below :

       /// <summary>
        /// Generates de Cenc config for Dash and Smooth Streaming.
        /// </summary>
        /// <returns>The Cenc configuration.</returns>
        protected static CommonEncryptionCenc GenerateCencConfig()
        {
            return new CommonEncryptionCenc()
            {
                Drm = new CencDrmConfiguration()
                {
                  PlayReady = new StreamingPolicyPlayReadyConfiguration(),
                  Widevine = new StreamingPolicyWidevineConfiguration()
                },
                EnabledProtocols = new EnabledProtocols()
                {
                    Hls = false,
                    Dash = true,
                    SmoothStreaming = true,
                    Download = false
                },
                ContentKeys = new StreamingPolicyContentKeys()
                {
                    // Default key must be specified if keyToTrackMappings is present
                    DefaultKey = new DefaultKey()
                    {
                        Label = "cencKeyDefault"
                    }
                }
            };
        }

        /// <summary>
        /// Generates de Cbcs config with offline FairPlayfor HLS-Ts and HLS-Cmaf.
        /// </summary>
        /// <returns>The Cenc configuration.</returns>
        protected static CommonEncryptionCbcs GenerateCbcsConfig()
        {
            return new CommonEncryptionCbcs()
            {
                Drm = new CbcsDrmConfiguration()
                {
                    FairPlay = new StreamingPolicyFairPlayConfiguration()
                    {
                        AllowPersistentLicense = true // this enables offline mode
                    }
                },
                EnabledProtocols = new EnabledProtocols()
                {
                    Hls = true,
                    Dash = true // Even though DASH under CBCS is not supported for either CSF or CMAF, HLS-CMAF-CBCS uses DASH-CBCS fragments in its HLS playlist
                },

                ContentKeys = new StreamingPolicyContentKeys()
                {
                    // Default key must be specified if keyToTrackMappings is present
                    DefaultKey = new DefaultKey()
                    {
                        Label = "cbcsKeyDefault"
                    }
                }
            };
        }

A colleague told me to check the app cert. Is it hosted somewhere? We guess you put the app cert URL in the textbox of the test player? In that case, it would be cross-domain javascript call. Please make sure the hosting site enable CORS.
