Abstract

The invention discloses a code rate adjusting method and device in a coding process, and the method comprises the steps: determining a complexity adjustment factor of a target video frame according tothe frame type and duration of the target video frame for the target video frame which has been subjected to complexity analysis; acquiring a current video frame to be coded, and calculating the long-term complexity corresponding to the current video frame according to the complexity of the target video frame subjected to the complexity analysis and the complexity adjustment factor; determining atarget value of the bit number of each pixel corresponding to the current video frame according to the long-term complexity and a preset reference value of the bit number of each pixel; and determining a target code rate value used for current coding according to the target value of the bit number of each pixel and the configuration parameter of the target video to which the current video frame belongs. According to the technical scheme provided by the invention, the convenience of code rate adjustment 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 and device in the encoding process. Background technique

[0002] With the continuous development of Internet technology, a large number of webcast platforms have emerged. While the live webcast platform brings real-time video experience to users, it also puts forward higher requirements on the network bandwidth of users. Currently, webcast platforms usually limit the bit rate of live video, so that the bit rate after limitation can adapt to the bandwidth that users can provide, thereby providing users with a smooth video experience.

[0003] Currently, when limiting the bit rate of live video, an upper limit is usually set, and the real-time bit rate of live video usually cannot exceed the upper limit of bit rate. However, if the bit rate upper limit is set too low, the picture quality of the live video will be poor; if the bit rate upper lim...
