JS SDK: trackSessionStart, heartbeat firing start events

in the sdk Version 2.1.0. Is it a normal behavior that if we call "trackSessionStart" on the "videoLoad" event the sdk fires "start" events every ~2seconds?

@stefanovualto Yes. It is normal behaviour to see multiple start events till the video has first started playing. We compute the "timeToStart" metric based on the total event durations of all the start events. The SDK sends multiple main:start events or in case of a preroll ad multiple ad:start events until the first call to trackPlay.

@praveek so when I fire TrackSessionStart the next events allowed are (only):

  • TrackPlay
  • AdBreakStart
  • AdStart

It is a normal behavior for the sdk to raise an error if others events are fired?

praveek commented

The following API calls are allowed after TrackSessionStart

  • TrackPlay
  • TrackPause
  • TrackEvent(SeekStart)
  • TrackEvent(BufferStart)
  • TrackEvent(AdBreakStart)
  • TrackEvent(ChapterStart)
  • TrackError

The SDK prints a warning and ignores other invalid API calls.
