Problems solved by technology

[0003] However, there are several problems in the existing Per-Title implementation scheme: first, the scheme requires a large number of repeated encodings for the same content, and the calculation is huge; second, in the on-demand application scenario, the transcoding template we provide for users is A fixed coding ladder, not optimal; third, the scheme is mainly aimed at video slices with a length in the second level, and it is difficult to extend to long videos; fourth, the implementation of the scheme requires additional user equipment information and Information such as network attributes, these data are difficult to obtain

Abstract

The present application discloses a data processing method and device. The specific implementation scheme is as follows: analyzing an encoded file of a video stream to obtain a target frame image set corresponding to the encoded file and each target quantization parameter corresponding to the target frame image set, wherein the target quantization parameter is the quantization parameter of the target frame image when the target frame image meets the quality evaluation index; based on the comparison result of each target quantization parameter corresponding to the target frame image set, the encoded file and the initial quantization parameter of each frame image of the video stream, Determine the new quantization parameter of each target frame image in the target frame image set and the new bit number of each target frame image corresponding to the new quantization parameter; according to the new quantization parameter and new bit number of each target frame image in the target frame image set , to update the initial quantization parameter and initial number of bits of each frame of the video stream. The scheme implements a data processing method optimized for coding efficiency.

Description

technical field [0001] The embodiments of the present application relate to the field of computer technology, in particular to the field of intelligent transportation technology, and in particular, to a data processing method and apparatus. Background technique [0002] With the development of streaming media technology, due to the huge difference between the devices users watch videos and the transmission bandwidth they have, in order to achieve the purpose of further reducing the bit rate without degrading the subjective quality, the content provided by users is divided into different Quality level, quality level can be understood as encoding ladder, and a coding efficiency optimization (Per-Title) method is proposed to customize encoding ladder for each content. The current Per-Title scheme also includes a machine learning-based Per-Title implementation scheme and a Context Aware Encoding (CAE) implementation scheme. [0003] However, there are several problems in the ex...
