Abstract

The invention discloses an adaptive video transcode method based on contents, and the method comprises the steps: obtaining a minimum quantitative value which meets a preset objective quality standard and is used for representing the complexity degree of to-be-transcoded video contents; setting the value of a transcode parameter according to the minimum quantitative value of the complexity degree of to-be-transcoded video contents and a video parameter value of a to-be-transcoded video; and transcoding the to-be-transcoded video according to the set transcode parameter and generating a target video. The invention also provides an adaptive video transcode device based on contents. The method provided by the invention can avoid the unnecessary consumption of bandwidth while guaranteeing video quality after transcoding.

Description

technical field [0001] The present application relates to video transcoding technology, in particular to a content-based adaptive video transcoding method. The present application also provides a content-based adaptive video transcoding device. Background technique [0002] With the leap of information technology, the application of multimedia technology in the network has achieved unprecedented development, and the video communication technology, which is an important part of multimedia technology, has also been greatly developed and applied. Since different videos may use different encoding or compression standards, and specific application scenarios may also be different, video transcoding operations are usually required when sharing, exchanging, or playing video files between different devices. [0003] Video transcoding (Video Transcoding) refers to converting a compressed and encoded video stream into another video stream to adapt to different network bandwidths, diff...
