Video transcoding method, apparatus, device and medium

Abstract

Embodiments of the present disclosure disclose a video transcoding method, apparatus, device, and medium. The method includes: in a current transcoding cycle, transcoding a first video in a transcoding queue by using a first encoding method, and transcoding all The second video outside the transcoding queue is transcoded by the second encoding method; the video heat of the first video is greater than or equal to the heat threshold; for the same video, when the same video quality is transcoded, the first encoding method The video bit rate of the first video is less than the video bit rate of the second encoding mode; the transcoding delay of the transcoding queue is less than the delay threshold, and the number of the first video transcoded in the current transcoding cycle is less than the first number threshold In the case of , reduce the hotness threshold as the hotness threshold of the next transcoding cycle. Under the premise of making full use of computing resources, the embodiments of the present disclosure transcode video to the maximum extent by using an encoding method with a low video bit rate, so as to improve the viewing experience of the transcoded video.

Description

technical field [0001] The embodiments of the present disclosure relate to video processing technologies, and in particular, to a video transcoding method, apparatus, device, and medium. Background technique [0002] Video transcoding requires a lot of computing resources. When resources are limited, the number of videos to be transcoded must be controlled to ensure the stability of the transcoding service and the reasonable allocation of computing resources. When the same video is transcoded with the same video quality, the video bit rates of different encoding methods are different. Users who watch the transcoded video obtained by the encoding method with a lower video bit rate have a better viewing experience. The transcoding process of the coding mode with low bit rate consumes more computing resources than the transcoding process of the coding mode with high video bit rate. [0003] In the scenario of User-Generated Content (UGC), the magnitude of the video is large. G...

AI Technical Summary

Problems solved by technology

[0003] In the scenario of user-generated content (User-Generated Content, UGC), the magnitude of the video is large. Generally, videos whose popularity is greater than the popularity threshold are transcoded with a low video bit rate encoding method, and videos whose popularity is less than or equal to the popularity threshold. Transcoding with a coding method with a high video bit rate can ensure the stability of the system during the peak period of video playback, but it will cause a lot of waste of computing resources during the low-peak period of video playback
