Abstract

The embodiment of the invention provides a video code rate switching method and device, electronic equipment and a medium. The method relates to the technical field of computers, and comprises the steps of determining a downloading speed value of a target video and a playing time length corresponding to cache data of the target video after the target video is played for a specified time length, and then adjusting a code rate of the target video based on the playing time length and the downloading speed value. The downloading speed value is the real-time downloading speed or the predicted downloading speed of the target video, the predicted downloading speed is the downloading speed predicted according to the data size and the downloading duration of the to-be-predicted video slice, the to-be-predicted video slice is the latest downloaded preset number of video slices, and the cache data is the downloaded but unplayed video data. According to the method disclosed in the invention, the video code rate can be prevented from being frequently switched.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, electronic equipment and medium for switching video code rates. Background technique [0002] At present, when a user uses an electronic device to watch a video, he will use the function of automatically switching the video bit rate in the video client, so as to realize the purpose that the video bit rate can automatically adapt to the current network environment. Wherein, the electronic device may include a mobile terminal or a personal computer (personal computer, PC) terminal having a video playing function. [0003] In the prior art, when the electronic device switches the video bit rate according to the network environment, it will obtain the real-time download speed of the video file downloaded by the electronic device, and judge whether to switch the video bit rate according to the real-time download speed. If the real-time download speed is g...
