Problems solved by technology

However, for different scenarios, it is a difficult problem to adjust which parameters and how to adjust them.
[0004] The existing parameter adjustment method usually adopts the method of all permutation and combination of parameters, and each parameter needs to test 4 code rate points to calculate the encoding quality under this parameter as one of the evaluation indicators, and all parameters in the scene need to be tested The test sequence traverses the test, and the entire parameter adjustment process is computationally complex and time-consuming

Abstract

The invention relates to a method and device for adjusting encoder parameters, computer equipment and a storage medium. The parameter adjustment process is used as a mode of solving multiple local optimalities, namely, an independent local optimal solution of each parameter is firstly solved, and then a combined local optimal solution is solved by integrating all the parameters. The sequencing isconducted according to the maximum coding performance of a single parameter; a to-be-updated sequence of each parameter is determined; the to-be-updated sequence of each parameter value correspondingto each parameter is determined according to the coding performance of each parameter value of the single parameter, and the parameter value of each parameter according to the to-be-updated sequence is sequentially adjusted. therefore, the parameter value of each parameter is determined, and the complexity of the parameter determination process is reduced.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method, device, computer equipment and storage medium for adjusting encoder parameters. Background technique [0002] Video encoding refers to the method of converting an original video format file into another video format file through compression technology. The most important codec standards in video streaming are H.264, H.265, AVS and so on. [0003] For different practical application scenarios and different video types (such as games, sports, variety shows, etc.), you can adjust the video encoding parameters to improve the encoding quality without greatly changing the encoding speed, or without greatly changing the encoding quality to increase the encoding speed. However, for different scenarios, which parameters to adjust and how to adjust them are difficult problems. [0004] The existing parameter adjustment method usually adopts the method of all permut...
