I'm attempting to decrypt an MPEG Dash stream protected with PlayReady using Win8.1/IE11/Dash Reference Player (http://dashif.org/reference/players/javascript/v1.6.0/samples/dash-if-reference-player/index.html). A license is successfully acquired from the server but the browser immediately afterwards reports MEDIA_ERR_ENCRYPTED with a msExtendedCode of "MF_E_INCOMPATIBLE_SAMPLE_PROTECTION (0xC00D7176) The sample protection algorithms supported by components are not compatible".
Can anyone shed some light on this error code and offer any troubleshooting tips?
