1. A video stream processing method, comprising:
receiving a first group of coded picture frames in a video stream;
determining a storage time and a network request protection time corresponding to the first group of coded picture frames, the storage time being an amount of time an intra frame of the first group of coded picture frames is stored for transmission to a network node;
when the storage time is greater than a preset time threshold and a preset condition is met, indicating a transmission conflict with at least one second terminal occurs in a process of transmitting the intra frame to the network node, determining a start time of at least a second group of coded picture frames in the video stream according to the storage time and the network request protection time, the second group of coded picture frames being after the first group of coded picture frames; and
transmitting an intra frame of the second group of coded picture frames to the network node based on the start time of the second group of coded picture frames.
