A method and device for video transcoding

Abstract

The invention discloses a video transcoding method and device, and belongs to the technical field of the computer. The method comprises the following steps: acquiring a video data packet of a de-encapsulated target video; periodically computing the overall average code rate of the target video and the local average code rate in the preset period; adjusting the coding rate according to the overallaverage code rate and the local average code rate; and performing transcoding processing on the target video based on the adjusted coding rate. By using the method and device disclosed by the invention, the basic consistency of the code rate of the output video and the code rate of the input video can be furthest guaranteed, and the video transcoding effect can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video transcoding method and device. Background technique [0002] With the development of Internet technology and the continuous increase of modern bandwidth, the connection between the Internet and people's lives is becoming closer and closer. More and more people are keen to obtain videos on the Internet to enrich their lives. At present, high-quality and high-quality videos have become The first choice for people's daily needs. [0003] Based on the needs of publicity or copyright protection, video publishers often add exclusive watermarks to the published video data to prevent the video data from being stolen by others. Specifically, the publisher can first obtain the packaged initial video (which can be called the input video), then decapsulate and decode the video data of the initial video, and then add a watermark to each frame of the video, and then publish ...

Problems solved by technology

[0005] If the code rate of the transcoded video is too small, the image quality of the video will be poor, and even picture distortion or mosaic phenomenon will appear, and if the code rate of the video after transcoding is too high, it will lead to the loss of bandwidth resources when transmitting the video. Waste, in this way, the bit rate of the output video needs to be as close as possible to the bit rate of the input video

However, due to the influence of different encoding modes, it is difficult to accurately know the bit rate of the input video during transcoding, so the effect of video transcoding is poor
