Order of playback events

Browser TVSDK dispatches events/notifications in generally expected sequences. Your player can implement actions based on events in the expected sequence.

The following examples show the order of some events that include playback events.

  • When successfully loading a media resource through replaceCurrentResource, the order of events is:

    • AdobePSDK.MediaPlayerStatusChangeEvent with event.status =

      • MediaPlayerStatus.INITIALIZING
      • MediaPlayerStatus.INITIALIZED
  • When preparing for playback through MediaPlayer.prepareToPlay, the order of events is:

    • AdobePSDK.MediaPlayerStatusChangeEvent with event.status =

      • MediaPlayerStatus.PREPARING
      • MediaPlayerStatus.PREPARED

The following example shows a typical progression of events:

player.addEventListener(AdobePSDK.PSDKEventType.STATUS_CHANGED,  
                                 onStatusChange); 
 
onStatusChange = function (event) { 
 
    switch (event.status) { 
        case AdobePSDK.MediaPlayerStatus.IDLE: 
            console.log("Player Status: IDLE"); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.INITIALIZING: 
            console.log("Player Status: INITIALIZING"); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.INITIALIZED: 
            console.log("Player Status: INITIALIZED"); 
            player.prepareToPlay(); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.PREPARING: 
            console.log("Player Status: PREPARING"); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.PREPARED: 
            console.log("Player Status: PREPARED"); 
            if (autoPlay) { 
                player.play(); 
            } 
            else { 
                dispatchEvent(ReferencePlayer.Events.PreparedEvent,  
                              {target: this}); 
            } 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.PLAYING: 
            console.log("Player Status: PLAYING"); 
            //update UI play/pause to show pause icon 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.PAUSED: 
            console.log("Player Status: PAUSED"); 
            //update UI play/pause to show play icon &  
            //display pause icon over video 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.SEEKING: 
            console.log("Player Status: SEEKING"); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.COMPLETE: 
            console.log("Player Status: COMPLETE"); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.RELEASED: 
            console.log("Player Status: RELEASED"); 
            break; 
 
        case AdobePSDK.MediaPlayerStatus.ERROR: 
            console.log("Player Status: ERROR"); 
            break; 
    } 
};
