Abstract

The invention discloses a video coding method and device in a cloud technology scene, a storage medium and electronic equipment, and particularly relates to technologies such as cloud computing and big data. The method comprises the following steps: determining a to-be-coded video frame from a to-be-played video stream; under the condition that the average SATD value of the sum of residual absolute values of all pixels in the video frame to be coded is obtained, a target quantization parameter is obtained according to the average SATD value and the target bit number corresponding to the maximum bit rate of the video frame to be coded, the average SATD value is used for indicating the content complexity of the video frame to be coded, and the target bit number is used for indicating the maximum bit rate of the video frame to be coded. The target quantization parameter is used for indicating an output code rate of the to-be-coded video frame; and coding the video frame to be coded according to the output code rate indicated by the target quantization parameter. According to the invention, the technical problem of low video coding accuracy is solved.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a video coding method, apparatus, storage medium, and electronic equipment. Background technique [0002] Today, with the rapid development of information technology, the application of online video is growing rapidly, and its core value is gradually extending to the downstream of the industrial chain, promoting the integration of different industries. In 2015, 85% of the data exchanged on the Internet was already occupied by video streaming. Compared with image and audio data, video data has the characteristics of relatively large storage and transmission scale, and will face more challenges in network distribution, especially some new applications such as ultra-high-definition user experience are limited by technical bottlenecks. Limited by the real-time variable and relatively limited network bandwidth, the playback quality of network video services is often unsatisfacto...
