after the required structural body and function pointer are determined, media head information of audio and video stream data is obtained through callback of the media head function pointer, and the media head information is callback to the player module through a callback interface.
Specifically, when the player module starts the P2P module, the player module sends the callback interface parameter, the media head function pointer and the data function pointer to the P2P module, that is, before the media head information of the audio/video stream data is obtained by the callback media head function pointer, the method further includes:
