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

Embodiments of the present invention disclose a bit rate adjustment method, a server, and a computer-readable medium, wherein the method includes: the server receives a video slice sent by a terminal, and the video slice includes a first video frame and a second video frame; the first video frame includes The last frame of video image before the video slice point, the second video frame includes the first frame of video image after the video slice point; if the code rate determined by the actual encoding information of the first video frame and the code determined by the actual encoding information of the second video frame If the difference between the rates is greater than the threshold, the actual encoding information of the first video frame is adjusted so that the difference is less than or equal to the threshold. By implementing the present application, it is possible to avoid the problem of different bit rates between video slices after slicing, and improve the continuity of picture definition at the video slice points.

Description

technical field [0001] The present invention relates to the field of Internet technologies, and 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. Essentially, transcoding is a process of decoding and then encoding. [0003] In the prior art, the mainstream video transcoding method includes the following steps: first, the original video file is processed into slices, and multiple video slices can be obtained. Figure 1A Second, each video slice is sent to different servers for encoding, so as to obtain the code stream corresponding to each video slice respectively; Get the full video file. Specifically, see Figure 1B , Figure 1B It is an operation schematic diagram of a distributed video tra...
