Buffer start

The buffer start event signals that the media player entered a buffering state.

Web SDK

Call sendEvent with eventType: "media.bufferStart":

alloy("sendEvent", {
  xdm: {
    eventType: "media.bufferStart",
    mediaCollection: {
      sessionID: "{sid}",
      playhead: 45
    }
  }
});

Mobile SDK

Call trackEvent with BufferStart when the player enters a buffering state, and BufferComplete when it exits.

iOS (Swift)

// Buffer starts
tracker.trackEvent(event: MediaEvent.BufferStart, info: nil, metadata: nil)

// Buffer ends
tracker.trackEvent(event: MediaEvent.BufferComplete, info: nil, metadata: nil)

Android (Kotlin)

// Buffer starts
tracker.trackEvent(Media.Event.BufferStart, null, null)

// Buffer ends
tracker.trackEvent(Media.Event.BufferComplete, null, null)
