Abstract

The invention discloses a video conversion method and device, and relates to the technical field of digital media. The video conversion method and device solves the problems that in the prior art, after a video is converted, a target video is low in quality, and poor in user experience. The method includes the steps of receiving a video source, obtaining compression artifact quality of the video source, obtaining transcoding strategies corresponding to the compression artifact quality of the video source according to the compression artifact quality of the video source, judging whether the video source needs transcoding according to the transcoding strategies, if yes, generating transcoding parameters according to the transcoding strategies, wherein the transcoding strategies comprise target video quality, and the transcoding parameters comprise a target resolution ratio, a target frame rate and a target code rate, converting the video source according to the target resolution ratio, the target frame rate and the target code rate, and generating a transcoded video. The video conversion method and device can be applied to network devices (like a network server) or terminal devices (like a telephone mobile terminal, a tablet computer and a notebook computer).

Description

technical field [0001] The invention relates to the technical field of digital media, in particular to a video conversion method and device. Background technique [0002] Video conversion technology is widely used in video broadcast transcoding, video surveillance, digital media adapters, and high-definition video conferencing and other scenarios. Video conversion refers to converting a compressed and encoded video stream into another video stream to adapt to different network bandwidths, different terminal processing capabilities, and different user needs. [0003] Among the current video conversion methods, one is to pre-set different resolutions corresponding to different bit rates, for example, a resolution of 320*240, corresponding to a bit rate of 100,000 bits per second; another example, 640*480, corresponding to a bit rate of 120,000 bits Every second, etc., according to the resolution to be converted during video conversion, the bit rate corresponding to the resolu...
