Abstract

The invention discloses a video conversion method and device, equipment and a medium. The video conversion method comprises the steps of downloading target video, and decoding the target video; converting the format of frames in the target video from a YUV format into an RGB format according to the following formulas: R=Y, G=Y and B=Y, wherein R is an R-channel parameter value of the RGB format, Gis a G-channel parameter value of the RGB format, B is a B-channel parameter value of the RGB format, Y is a Y-channel parameter value of the YUV format, U is a U-channel parameter value of the YUV format, and V is a V-channel parameter value of the YUV format; and performing video analysis on the target format with the format being converted. The method and device provided by the invention can solve a technical problem that video analysis in the prior art is great in calculation amount and slow in processing speed, and realizes the technical effect of improving the efficiency and speed of video analysis.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a video conversion method, device, equipment and medium. Background technique [0002] At present, with the advancement of network communication technology and the speed-up of broadband network, webcasting has been more and more developed and applied. In order to ensure the healthy development of the live broadcast and obtain the data information of the live broadcast process, it is often necessary to monitor whether there are unqualified video images in the live video, or to analyze and obtain key data in the live video, so that the live broadcast platform can take improvement measures. All of this needs to be carried out through video analysis during the live broadcast or after the video is obtained. [0003] However, whether it is synchronous video analysis during live broadcast or analysis of existing video, it needs to consume more resources for decoding, conversi...
