Abstract

The present application discloses a code rate adaptive switching method, device, electronic equipment and storage medium, which are used to solve the problem of low switching efficiency of media files with different code rates. The method includes: determining the first code rate file in the target media file set, and playing the first code rate file; determining the code rate file to be switched and the index information corresponding to the code rate file to be switched that meet the preset switching conditions; according to the index Information, determine the target key frame timestamp for switching from the first code rate file to the code rate file to be switched, and determine the position of the target key frame in the code rate file to be switched according to the target key frame timestamp; in the first code rate file When playing to the moment corresponding to the target key frame timestamp, switch the first code rate file to the code rate file to be switched at the position of the target key frame corresponding to the target key frame timestamp in the code rate file to be switched.

Description

technical field [0001] The present disclosure relates to the field of communication technologies, and in particular to a code rate adaptive switching method, device, electronic equipment, and storage medium. Background technique [0002] At present, for the same media file (such as a video file), there are different performances when the client plays media files with different bit rates in different network environments. Specifically, playing low-bit-rate media files on the client side can ensure the smoothness of playback in a poor network environment, but cannot meet the requirements for the clarity of the playback screen; However, for a poor network environment, the fluency of media file playback is poor. Therefore, it is necessary to perform transcoding between multiple code rates on the media file. [0003] In related technologies, when switching and playing multi-bit-rate media files, the client can only switch bit-rates between slices, that is, the current slice dat...
