Track chapters and segments on Roku

Identify when the chapter start event occurs and create the ChapterObject instance by using the chapter information.

ChapterObject chapter tracking reference:

NOTE

These variables are only required if you are planning to track chapters.

Chapter object:

chapterInfo =
  adb_media_init_chapterinfo(<CHAPTER_NAME>,
                             <POSITION>,
                             <LENGTH>,
                             <START_TIME>);)

If you include custom metadata for the chapter, create the context data variables for the metadata:

chapterContextData = {}
chapterContextData["seg_type"] = "seg_type"
chapterContextData["seg_name"] = "seg_name"
chapterContextData["seg_info"] = "seg_info"

To begin tracking the chapter playback, call the ChapterStart event in the MediaHeartbeat instance:

ADBMobile().mediaTrackEvent(MEDIA_CHAPTER_START, chapterInfo, chapterContextData)

When playback reaches the chapter end boundary, as defined by your custom code, call the ChapterComplete event in the MediaHeartbeat instance.

chapterContextData = {}
ADBMobile().mediaTrackEvent(MEDIA_CHAPTER_COMPLETE, chapterInfo, chapterContextData)

If chapter playback did not complete because the user chose to skip the chapter (for example, if the user seeks out of the chapter boundary), call the ChapterSkip event in the MediaHeartbeat instance.

chapterContextData = {}
ADBMobile().mediaTrackEvent(MEDIA_CHAPTER_SKIP, chapterInfo, chapterContextData)

If there are any additional chapters, repeat steps 1 through 5.
