Abstract

The invention belongs to the technical field of video coding, and discloses a video transcoding method, device and equipment and a medium, and the method comprises the steps: receiving to-be-transcoded video coding data, decoding the video coding data, obtaining corresponding video image data and coding parameter information; and according to the coding parameter information of the video image data, estimating the coding complexity of recoding the video image data, and recoding the video image data according to a transcoding strategy corresponding to the coding complexity to obtain video transcoding data. Thus, according to the coding complexity of video image data transcoding, the transcoding configuration information is adaptively adjusted, so that different video image data is subjectedto differential coding, and the video quality is ensured.

Description

technical field [0001] The present application relates to the technical field of video coding, and in particular to a video transcoding method, device, device and medium. Background technique [0002] Video transcoding technology is used to convert video data from one format to another, and is an important technology for video communication between traditional and emerging devices. For example, many existing video conferencing systems are established based on the old video coding standard H.264, while the latest video conferencing systems adopt the H.265 baseline specification. Therefore, when performing video communication between devices adopting different video coding standards, video data needs to be transcoded. [0003] In the prior art, generally unified transcoding configuration information is used to transcode video encoded data. However, the same transcoding configuration information is used to encode different video encoding data, so that the video quality cannot...
