A transcoding method and processing terminal for adaptive video aspect ratio

Abstract

The invention relates to a self-adaptive video aspect ratio transcoding method and a processing terminal, and the method comprises the following steps: S1, obtaining a to-be-transcoded source video file which at least comprises video aspect ratio information; s2, judging a type group suitable for transcoding of the source video file according to the video width and height information, wherein thetype group represents video parameter information after transcoding of the source video file, and the video parameter information at least comprises the maximum resolution; and S3, circularly transcoding the videos of the type groups in sequence, calculating the size of a transcoded video adaptive to the maximum resolution according to the reference edge and the maximum resolution, and performingtranscoding by taking the size of the transcoded video as a video transcoding parameter to obtain a transcoded video, thereby finishing video transcoding. Compared with the existing transcoded video,the transcoded video has the advantages that under the same size, the pixel utilization rate is the highest, the picture is the clewest, the transcoded video can adapt to a playing terminal, and a black edge condition is not generated.

Description

technical field [0001] The invention relates to the technical field of video transcoding, in particular to an adaptive video aspect ratio transcoding method and a processing terminal. Background technique [0002] At present, most of the transcoded videos are adapted to the horizontal screen, and cannot be truly adapted to the vertical screen. If the transcoded video is applied to the vertical screen, the video under the vertical screen will be forcibly pasted on the horizontal screen. In order to meet the needs of the hard decoding of the player. Since the decoding of the video player is usually performed according to several established standards such as 4K, Full HD, HD, C1, etc., when either the wide side or the high side of the video exceeds the decoding size of the corresponding standard, hard decoding cannot be performed. However, the current video transcoding uses the horizontal screen as the transcoding reference side, and the other side is a black border (for examp...
