Description

Constant for attaching standard metadata on MediaObject

Implementation

Instantiate a standard metdata object, populate the desired variables, and set the metadata object on the Media Heartbeat object. For example:
_onVideoLoad = function () {
    //Create the Media Object   
    var mediaInfo =  
      MediaHeartbeat.createMediaObject(<MEDIA_NAME>,  
                                       <MEDIA_ID,  
                                       <MEDIA_LENGTH>,
                                       <STREAM_TYPE>,
                                       <MEDIA_TYPE>);

    //Set standard Video Metadata
    var standardMediaMetadata = {};     
    standardMediaMetadata[MediaHeartbeat.VideoMetadataKeys.SHOW] = "Sample Show";
    standardMediaMetadata[MediaHeartbeat.VideoMetadataKeys.SEASON] = "Sample Season";
    standardMediaMetadata[MediaHeartbeat.VideoMetadataKeys.EPISODE] = "Sample Episode";

    //Set standard Audio Metadata
    var standardMediaMetadata = {};     
    standardMediaMetadata[MediaHeartbeat.AudioMetadataKeys.ARTIST] = "Sample Artist";
    standardMediaMetadata[MediaHeartbeat.AudioMetadataKeys.ALBUM] = "Sample Album";
    standardMediaMetadata[MediaHeartbeat.AudioMetadataKeys.LABEL] = "Sample Label";

    mediaInfo.setValue(MediaObjectKey.StandardMediaMetadata, standardMediaMetadata);
    this._mediaHeartbeat.trackSessionStart(mediaInfo, contextData);
};
