acquiring a callback function according to the playing rule, and judging whether the event is a processing event of the video stream or not according to the callback function;
when the event is a processing event of the video stream, slicing and packing the video stream corresponding to the camera in batches to determine packed data;
stopping pointer skipping of the callback function when the event is not a processing event of the video stream.
8. The method of claim 1, wherein the converting the video coding format and the video frame adjustment of the packed data based on the preset national standard 28181 protocol, determining an adjusted video, and transmitting the adjusted video to a preset server comprises:
based on a preset national standard 28181 protocol, carrying out video coding format conversion on the packed data, and determining converted video data;
carrying out video frame adjustment on the converted video data, and determining adjustment data and an adjustment video;
carrying out rule analysis on the adjustment data, and transmitting an analysis result to a player SDK;
and transmitting the adjusted video to a preset server.
