Problems solved by technology

[0004] However, in the traditional video stream transcoding migration method, after the first transcoding server stops transcoding the original video stream, the second transcoding server re-pulls the original video stream and transcodes the output stream.
In this way, the second transcoding server needs to spend a certain amount of time to pull the original transcoding stream, and the original video stream pulled by the second transcoding server may be inaccurate, making the played video screen prone to freezes and rollbacks Or the phenomenon that the picture jumps forward, and the smooth transition of the video picture cannot be realized

Abstract

The invention relates to a video stream transcoding migration method, device and system. The method comprises the following steps of: inquiring a reference timestamp of a first transcoding server fortranscoding an original video stream into a first transcoding stream; sending the reference timestamp to a second transcoding server, so that the second transcoding server transcodes the original video stream based on the reference timestamp to obtain a second transcoding stream; pulling the second transcoding stream, and keeping pulling the first transcoding stream from the first transcoding server, wherein the second transcoding stream has a time stamp determined based on the reference time stamp; and keeping outputting the first transcoding stream until the timestamps of the first transcoding stream and the second transcoding stream are monitored to be aligned, and switching the output first transcoding stream into the second transcoding stream. By adopting the scheme provided by the invention, when video stream transcoding migration is carried out, smooth transition of a real-time video playing image can be realized.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a video stream transcoding migration method, device, system, computer-readable storage medium and computer equipment. Background technique [0002] With the development of computer technology, cloud video transcoding technology has emerged, which can convert the original video stream into live video streams with different resolutions, such as different resolutions and different bit rates. Users can choose to watch live video streams with different resolutions such as Blu-ray, HD, SD, and PHD according to their network conditions. [0003] However, cloud video transcoding consumes a lot of resources on the transcoding server. In order to maximize the use of transcoding server resources, traditional video stream transcoding migration methods often switch transcoding tasks to other idle transcoding servers to achieve arbitrary migration and switching of transcoding task...
