Korunan içeriği yürütme iş akışı

  1. Bir MediaPlayer örneği oluşturun.
    player = new MediaPlayer();
  2. MediaPlayerCapabilityChangeEvent.HAS_DRM_CHANGE olayını oynatıcıya kaydedin. Bu olay içerik DRM korumalı ise gönderilir.
    player.addEventListener(MediaPlayerCapabilityChangeEvent.HAS_DRM_CHANGE, onDRMCapabilityChange);
  3. Olay işleyicide DRMTrait örneğini edinin. DRMTrait , authenticate() gibi DRM ile ilişkili yöntemleri çağırdığınız arabirimdir. DRM korumalı bir içeriği yüklerken OSMF, DRM doğrulama işlemlerini gerçekleştirir ve durum olayları gönderir. DRMTrait öğesine bir DRMEvent.DRM_STATE_CHANGE olay işleyicisi ekleyin.
    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); 
                } 
            }
  4. DRM olaylarını onDRMStateChange() yönteminde işleyin.
            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:

                        {

                        } 
                        else 
                        // You have got the voucher. 
                        { 
                            trace("DRM License:");                         
                            trace("Playback window period: ", 
                                !isNaN(event.period) ? event.period == 0 ?

                        } 
                        break; 
                    case DRMState.AUTHENTICATION_ERROR:
