/** Registers a packet observer.
*
* The Agora RTC SDK allows your application to register a packet observer to receive callbacks for voice or video packet transmission.
*
* @note
* - The size of the packet sent to the network after processing should not exceed 1200 bytes, otherwise, the packet may fail to be sent.
* - Ensure that both receivers and senders call this method, otherwise, you may meet undefined behaviors such as no voice and black screen.
* - When you use CDN live streaming, recording or storage functions, Agora doesn't recommend calling this method.
*
*
* @return
* - 0: Success.
* - < 0: Failure.
