Embodiment Construction

[0045] Embodiments of the present application are described below in conjunction with the accompanying drawings.

[0046] In order to solve the technical problems existing in related technologies, the embodiment of the present application provides a video encoding method, which adopts different quantization parameter values ​​for video encoding according to the region of interest and the region of non-interest, so that the target of the image block belonging to the region of interest The quantization parameter value is smaller than the target quantization parameter value for the image blocks belonging to the non-region of interest. In this way, while ensuring video clarity, the traffic generated by video encoding is reduced, thereby reducing the network transmission bandwidth occupied by the video stream during the process of transmitting the video stream from the server to the terminal, and improving transmission efficiency.

[0047]The method provided in the embodiment of th...

Abstract

The embodiment of the invention discloses a video coding method and device, equipment and a storage medium, and the method comprises the steps: enabling a server to obtain a to-be-coded target video frame sequence when video coding needs to be carried out, and determining a region of interest in the target video frame image for each target video frame image in the target video frame sequence; andadjusting the initial quantization parameter values of the image block of the region of interest and the image block of the non-region of interest in the target video frame image to obtain a target quantization parameter value, so that the target quantization parameter value of the image block belonging to the region of interest is smaller than the target quantization parameter value of the imageblock belonging to the non-region of interest. Thus, in the process of encoding the target video frame sequence according to the target quantization parameter value to obtain the video stream, more code rates are allocated to the region of interest, the definition is ensured, less code rates are allocated to the non-region of interest, and the flow generated by video encoding is reduced, so that the network transmission bandwidth occupied by the video stream is reduced, and the transmission efficiency is improved.

Description

technical field [0001] The present application relates to the field of data processing, in particular to a video encoding method, device, equipment and storage medium. Background technique [0002] Video coding refers to the technology of converting a video format file into another video format file by eliminating redundant information in the time domain between consecutive video frames to realize the function of compressing video. [0003] In related technologies, after the server obtains the video to be encoded, for each video frame image in the video to be encoded, the server uses the determined encoding parameters to perform video encoding on the entire video frame image, and converts the video into a video stream. The terminal sends the video stream. [0004] With the continuous improvement of video definition requirements, when the above method is used for video encoding, the traffic generated by the video encoding is too high, and the video stream occupies a large ne...
