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

The invention discloses a data processing method and device, and the specific implementation scheme is that the method comprises the steps: analyzing a coding file of a video stream to obtain a target frame image set corresponding to the coding 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; determining a new quantization parameter of each target frame image in the target frame image set and a new bit number of each target frame image corresponding to the new quantization parameter based on a comparison result of each target quantization parameter corresponding to the target frame image set, the coding file and an initial quantization parameter of each frame image of the video stream; and according to the new quantization parameter and the new bit number of each target frame image in the target frame image set, updating the initial quantization parameter and the initial bit number of each frame image of the video stream. According to the scheme, the data processing method aiming at coding efficiency optimization is realized.
Description
technical field [0001] The embodiments of the present application relate to the field of computer technology, specifically to the field of intelligent transportation technology, and especially to data processing methods and devices. Background technique [0002] With the development of streaming media technology, due to the huge difference in the equipment and transmission bandwidth owned by users to watch videos, in order to achieve the purpose of further reducing the bit rate without reducing the subjective quality, the content provided by users is divided into different streams. Quality level, quality level can be understood as a coding ladder, and a coding efficiency optimization (Per-Title) method for customizing the coding ladder for each content is proposed. The current Per-Title solution also includes a machine learning-based Per-Title implementation and a Context Aware Encoding (CAE) implementation. [0003] However, there are several problems in the existing Per-T...
