Video stream sending method and device, computer equipment and storage medium

The invention relates to the technical field of artificial intelligence, and provides a video stream sending method and device, computer equipment, a storage medium and a computer program product. According to the invention, the efficiency and accuracy of video stream sending can be improved. The method comprises the following steps: receiving model parameters of a target view angle information prediction model sent by a server; the model parameters of the target visual angle information prediction model are obtained by performing aggregation processing on model parameters in a basic visual angle information prediction model pre-trained on each terminal through the server; updating model parameters in a basic view angle information prediction model pre-trained on the terminal by using the model parameters of the target view angle information prediction model to obtain the target view angle information prediction model; determining predicted view angle information of an object to which the terminal belongs at
