A multimedia data processing method includes: acquiring a first predicted bit rate predicted by a bit rate prediction neural network based on first network data; performing classification and regression learning on the first network data and the first predicted bit rate to obtain a first bit rate prediction model; acquiring second network data and a second predicted bit rate predicted by the first bit rate prediction model, and the second network data being collected during playback of multimedia data using the second predicted bit rate; and performing classification and regression learning on the first bit rate prediction model based on a difference between the first network data and the second network data and a difference between the first predicted bit rate and the second predicted bit rate, to obtain a second bit rate prediction model configured to perform bit rate prediction in a terminal that plays the multimedia data.

Multimedia data processing method and apparatus, device, and readable storage medium

The present disclosure discloses a video preloading method and apparatus. The method includes: obtaining a playing request for playing a first video in a first application client; detecting a data transmission speed of a network of the first application client when playing the first video; adjusting, according to the detected data transmission speed, a preloading length of the first video in the first application client; and preloading, in the first application client, video frames of the first video based on the preloading length of the first video.

Video preloading method and apparatus

A method for reducing data transmission pressure of a server and to save network bandwidth resources includes sending advance backup data corresponding to multimedia files to N types of user terminals, where N&#x3e;1; receiving a data request that is sent by an (N+1)th type of user terminal and is used for requesting a multimedia file; and sending, to the (N+1)th type of user terminal, a link address, of advance backup data corresponding to the multimedia file, in the N types of user terminals, the link address being used for instructing the (N+1)th type of user terminal to acquire, from the N types of user terminals, data corresponding to the multimedia file.
