What is the relationship between the old and new callbacks of Media Push?

Agora provides two sets of callbacks for you to monitor Media Push:

  • Old callbacks: onStreamPublished and onStreamUnpublished.
  • New callbacks: onRtmpStreamingStateChanged and onRtmpStreamingEvent.

Agora has deprecated the old callbacks and recommends that you use the new callbacks. The old callbacks are still functional, however. You can choose the most appropriate set of callbacks to use according to your scenario and code logic. The relationship between the old and new callbacks is detailed in the following table:
