-
Maak een
MediaPlayer
-instantie.
player = new MediaPlayer();
-
Registreer de
MediaPlayerCapabilityChangeEvent.HAS_DRM_CHANGE
-gebeurtenis bij de speler. Deze gebeurtenis wordt verzonden als de inhoud via DRM is beveiligd.
player.addEventListener(MediaPlayerCapabilityChangeEvent.HAS_DRM_CHANGE, onDRMCapabilityChange);
-
Haal de
DRMTrait
-instantie op in een gebeurtenishandler.
DRMTrait
is de interface die u gebruikt voor het aanroepen van aan DRM gerelateerde methoden, zoals
authenticate()
. Tijdens het laden van door DRM beveiligde inhoud, voert OSMF de handelingen voor DRM-validatie uit en verzendt het statusgebeurtenissen. Voeg een
DRMEvent.DRM_STATE_CHANGE
-gebeurtenishandler toe aan de
DRMTrait
.
private function onDRMCapabilityChange
(event :MediaPlayerCapabilityChangeEvent) :void
{
if (event.type == MediaPlayerCapabilityChangeEvent.HAS_DRM_CHANGE
&& event.enabled)
{
drmTrait = player.media.getTrait(MediaTraitType.DRM) as DRMTrait;
drmTrait.addEventListener
(DRMEvent.DRM_STATE_CHANGE, onDRMStateChange);
}
}
-
Handel de DRM-gebeurtenissen af in de
onDRMStateChange()
-methode.
private function onDRMStateChange(event :DRMEvent) :void
{
trace ( "DRMState: ",event.drmState);
switch(event.drmState)
{
case DRMState.AUTHENTICATION_NEEDED:
// Identity-based content
var authPopup :AuthWindow = AuthWindow.create(_parentWin);
authPopup.serverURL = event.serverURL;
authPopup.addEventListener("dismiss", function () :void {
trace ("Authentication dismissed");
if(_drmTrait != null)
{
//Ignore authentication. Just
//try to acquire a license.
_drmTrait.authenticate(null, null);
}
});
authPopup.addEventListener("authenticate",
function (event :AuthWindowEvent) :void {
if(_drmTrait != null)
{
_drmTrait.authenticate(event.username, event.password);
}
});
authPopup.show();
break;
case DRMState.AUTHENTICATING:
//Display any authentication message.
trace("Authenticating...");
break;
case DRMState.AUTHENTICATION_COMPLETE:
// Start to retrieve voucher and playback.
// You can display the voucher information at this point.
if(event.token)
// You just received the authentication token.
{
trace("Authentication success. Token: \n", event.token);
}
else
// You have got the voucher.
{
trace("DRM License:");
trace("Playback window period: ",
!isNaN(event.period) ? event.period == 0 ?
"<unlimited>" : event.period : "<none>");
trace("Playback window end date: ",
event.endDate != null ? event.endDate : "<none>");
trace("Playback window start date: ",
event.startDate != null ? event.startDate : "<none>");
}
break;
case DRMState.AUTHENTICATION_ERROR:
trace ("DRM Error:", event.mediaError.errorID +
"[" + DRMErrorEventRef.getDRMErrorMnemonic
(event.mediaError.errorID) + "]");
//Stop everything.
player.media = null;
break;
case DRMState.DRM_SYSTEM_UPDATING:
Logger.log("Downloading DRM module...");
break;
case DRMState.UNINITIALIZED:
break;
}
}
