Problems solved by technology

However, if the bit rate upper limit is set too low, the picture quality of live video will be poor; if the bit rate upper limit is set too high, bandwidth will be wasted
Therefore, the current method of adjusting the bit rate of live video by setting the upper limit of the bit rate is often not convenient enough

Embodiment Construction

[0013] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0014] This application provides a code rate adjustment method in the encoding process, please refer to figure 1 , the method may include the following steps.

[0015] S1: For the target video frame for which the complexity analysis has been completed, determine the complexity adjustment factor of the target video frame according to the frame type and duration of the target video frame.

[0016] In this embodiment, when analyzing the complexity of the current video frame, in order to reduce the amount of data processed each time, the current video frame may be divided into a specified number of picture blocks. Wherein, each divided picture block may have the same size. In addition, the size of the divided picture block may be determined acc...

Abstract

The invention discloses a code rate adjustment method and device in an encoding process, wherein the method includes: for a target video frame whose complexity analysis has been completed, determining the target video frame according to the frame type and duration of the target video frame. the complexity adjustment factor of the target video frame; obtain the current video frame to be encoded, and calculate the corresponding Long-term complexity; determine the target value of bits per pixel corresponding to the current video frame according to the long-term complexity and the preset reference value of bits per pixel; according to the target value of bits per pixel and the current video frame The configuration parameter of the target video to which it belongs determines the target bit rate value used for the current encoding. The technical solution provided by the present application can improve the convenience of code rate adjustment.

Description

technical field [0001] The present invention relates to the field of Internet technologies, and in particular, to a method and device for adjusting a code rate in an encoding process. Background technique [0002] With the continuous development of Internet technology, a large number of online live broadcast platforms have emerged. While the webcast platform brings real-time video experience to users, it also puts forward higher requirements for users' network bandwidth. At present, online live broadcast platforms usually limit the bit rate of live video, so that the bit rate after the limitation can be adapted to the bandwidth that can be provided by the user, thereby providing users with a smooth video experience. [0003] At present, when limiting the bit rate of the live video, a bit rate upper limit is usually set, and the real-time bit rate of the live video usually cannot exceed the upper limit of the bit rate. However, if the upper limit of the bit rate is set too ...
