Track core playback on Chromecast track-core-playback-on-chromecast

Initial tracking setup

Identify when the user triggers the intention of playback (the user clicks play and/or autoplay is on) and create a MediaObject instance.

MediaObject API reference:

createMediaObject

mediaObject = ADBMobile.media.createMediaObject(<name>, <id>, <duration>, <streamType>, <mediaType>);

StreamType constants:

ADBMobile Media

MediaType constants:

ADBMobile Media

Attach video metadata

Optionally attach standard and/or custom video metadata objects to the video tracking session through context data variables.

• Standard video metadata

  Implement standard metadata on Chromecast

  note note
  NOTE
  Attaching the standard video metadata object to the media object is optional.

• Custom metadata

  Create a variable object for the custom variables and populate with the data for this video. For example:

  code language-js
  /* Set custom context data */ var customVideoMetadata = { isUserLoggedIn: "false", tvStation: "Sample TV station", programmer: "Sample programmer" };

Track the intention to start playback

To begin tracking a media session, call trackSessionStart on the media object.

ADBMobile.media.trackSessionStart(mediaObject, customVideoMetadata);

Track the actual start of playback

Identify the event from the video player for the beginning of the video playback, where the first frame of the video is rendered on the screen, and call trackPlay:

ADBMobile.media.trackPlay();

Update playhead value

Update mediaUpdatePlayhead’ position value multiple times when the playhead changes.
For video-on-demand (VOD), the value is specified in seconds from the beginning of the media item.
For live streaming, if the player does not provide information about the content duration, the value can be specified as the number of seconds since midnight UTC of that day.

ADBMobile().media.updatePlayhead(position)

Track the completion of playback

Identify the event from the video player for the completion of the video playback, where the user has watched the content until the end, and call trackComplete:

ADBMobile.media.trackComplete();

Track the end of the session

Identify the event from the video player for the unloading/closing of the video playback, where the user closes the video and/or the video is completed and has been unloaded, and call trackSessionEnd:

ADBMobile.media.trackSessionEnd();

Track all possible pause scenarios

Identify the event from the video player for video pause and call trackPause:

ADBMobile.media.trackPause();

Pause Scenarios

Identify any scenario in which the Video Player will pause and make sure that trackPause is properly called. The following scenarios all require that your app call trackPause():

• The user explicitly hits pause in the app.
• The player puts itself into the Pause state.
• (Mobile Apps) - The user puts the application into the background, but you want the app to keep the session open.
• (Mobile Apps) - Any type of system interrupt occurs that causes an application to be backgrounded. For example, the user receives a call, or a pop up from another application occurs, but you want the application to keep the session alive to give the user the opportunity to resume the video from the point of interruption.

Identify the event from the player for video play and/or video resume from pause and call trackPlay:

ADBMobile.media.trackPlay();
