Problems solved by technology

[0004] However, in practical applications, it can be found that due to the difference in the complexity of the original video file and other reasons, the code rate of the multiple video slices obtained after the original video file is sliced ​​​​is different, which leads to the final generated video. The video quality of the file fluctuates at the video slicing point, making the picture clarity lose continuity

Abstract

The embodiment of the present invention discloses a code rate adjusting method, a server, and a computer readable medium, wherein the method comprises the following steps: the server receives a videoslice sent by a terminal, wherein the video slice comprises a first video frame and a second video frame; the first video frame comprises a last frame video image before a video slice point, and the second video frame comprises a first frame video image after the video slice point; if the difference value between the code rate determined via a first video frame actual coded message and the code rate determined via a second video frame actual coded message is greater than a threshold, the first video frame actual coded message is adjusted, so that the difference value is smaller than or equal to the threshold. By implementing the application, the problem of inconsistent code rates occurring between the sliced video slices can be avoided, and the consistency of the picture sharpness at the video slice point can be improved.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a code rate adjustment method, a server and a computer-readable medium. Background technique [0002] Video transcoding refers to converting a compressed and encoded video stream into another video stream to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. In essence, transcoding is a process of first decoding and then encoding. [0003] In the prior art, the mainstream video transcoding method includes the following steps: first, slice the original video file to obtain multiple video slices, specifically, see Figure 1A ; Second, send each video slice to different servers for encoding to obtain the code stream corresponding to each video slice; third, splice the encoded code streams to generate a complete code stream, so that Get the full video file. Specifically, see Figure 1B , Figure 1B It is an operation ...
