Embodiment Construction

[0057] In order to make the purpose, technical solutions and advantages of the present application clearer, the present application will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0058] figure 1 It is an application scene diagram of a video coding method in an embodiment. refer to figure 1, first, the source video file is segmented to obtain a plurality of video slices, and then the video slices are transmitted to the server 102, and the server 102 performs parallel transcoding on each video slice, wherein the distributed cloud platform technology can be used for each video Slices are transcoded in parallel. Finally, the transcoded video slices are merged. It is easy to cause quality fluctuations at the joints of the merged videos. In order to minimize video q...

Abstract

The invention relates to a video coding method. The method comprises the following steps of: obtaining a forward video frame of the current video frame to be coded, obtaining corresponding evaluationinformation of the forward video frame in the current coding, determining a reference video slice corresponding to the current video frame, obtaining a reference video frame from the reference video slice, calculating and obtaining reference evaluation information corresponding to the current video frame according to the evaluation information corresponding to the reference video frame in the previous coding; obtaining an initial frame level quantization parameter corresponding to the current video frame in the current coding, and adjusting the initial frame-level quantization parameter according to the evaluation information corresponding to the forward video frame in the current coding and the reference evaluation information corresponding to the current video frame to obtain a target frame-level quantization parameter, and coding the current video frame according to the target frame-level quantization parameter. According to the video coding method, quality fluctuation at the jointis effectively reduced, and the video quality after video merging is improved. In addition, the invention also provides a video coding device, computer equipment and a storage medium.

Description

technical field [0001] The present application relates to the field of computer processing technology, in particular to a video encoding method, device, computer equipment and storage medium. Background technique [0002] With the continuous development of Internet technology, people put forward higher requirements for visual experience. In order to improve the video transcoding speed, it is proposed to slice the video file first to obtain multiple sub-video files, then concurrently transcode each sub-video file, and finally merge the transcoded sub-video files to improve video encoding s efficiency. Although this method can greatly increase the speed of video encoding, it is easy to cause fluctuations in the video quality at the junction when the video is merged, thereby affecting the video quality. Contents of the invention [0003] Based on this, it is necessary to address the above-mentioned problems and propose a video coding method, device, computer equipment and s...
