Abstract

The invention relates to an information collection method and device, a storage medium and electronic equipment. The method comprises the following steps: obtaining a plurality of reference frames from a target video, the target video comprises a plurality of video frames, and the plurality of reference frames belong to the plurality of video frames; each reference frame in the plurality of reference frames is coded by using a plurality of code rates to obtain a plurality of coding results, and the plurality of coding results are in one-to-one correspondence with the plurality of code rates; and obtaining a rate distortion curve corresponding to the target video according to the plurality of code rates and the plurality of coding results. According to the method and the device, the problem of too large data processing error caused by too low precision of the obtained R-D curve in an R-D curve obtaining mode in the related technology is solved.

Description

technical field [0001] The present application relates to the computer field, and in particular to an information acquisition method and device, a storage medium and an electronic device. Background technique [0002] The R-D (Rate-distortion, rate-distortion) curve is a very important "feature" in the video encoding process. Different videos have different R-D curves, and the R-D curve will also change after the encoder is changed. [0003] Currently, it is assumed that there is a strong correlation between video frames of a video when performing R-D curve estimation. During the encoding process, the R-D curves of the future frames are estimated by using the R-D results of the previous frames. [0004] However, even with correlation between video frames, errors still exist. Therefore, there is a certain error in predicting the R-D curve of future frames by using the R-D results of the previous frames. For some data processing scenarios that require high-precision R-D cur...
