Abstract

The invention discloses a video transcoding method, computer equipment and a storage medium, and the method comprises the steps: decoding an H265 video, and obtaining an H265 strip and the descriptioninformation of the H265 strip; and determining a frame type, a display time sequence label, an encoding time sequence label, a playing delay label, reference information, frame deletion information,a target macro block prediction mode and a target motion vector of an AVS2 target frame according to the description information, and then encoding according to the obtained information to obtain an AVS2 video. According to the method, the H265 video can be transcoded into the AVS2 video with less calculation amount, and the H265 video can be efficiently converted into the AVS2 video under the condition of ensuring that the output quality is not degraded.

Description

technical field [0001] The present application relates to the technical field of video processing, in particular to a video transcoding method, computer equipment and storage media. Background technique [0002] In today's China where 5G and high-bandwidth basic communication construction is in full swing, and as people's living standards continue to improve, our country took the lead in formulating China's 4K source standard format AVS2 to meet the increasing material and cultural needs of all walks of life. At present, there are still many video sources that are the international standard H265, and the baseband YUV signal can be restored by a standard decoder oriented to the international standard H265, and then re-encoded by an encoder that meets the new generation of video coding 4K standard AVS2 in China. AVS2 signal, which is called full solution and full editing mode. The biggest problem with this method is that the equipment cost of the whole system is too high, bec...
