Problems solved by technology

[0005] During peak hours when users watch live broadcasts, a transcoding server often needs to process a large number of transcoding tasks for live streams at the same time. In this way, the transcoding server will continue to be in a state of high-load data output, and it may even easily enter an overloaded state. There is a high probability of failure, resulting in the interruption or termination of live stream transcoding, so the quality of live service is poor

Embodiment Construction

[0057] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0058] An embodiment of the present invention provides a method for creating a transcoding task. The execution subject of the method may be a transcoding server, which is assisted by a streaming media server. Among them, the transcoding server can be used to receive the transcoding request of the streaming media server for the live stream, generate a corresponding transcoding task, and create a corresponding transcoding process, and then realize the transcoding process of the live stream through the transcoding process; The server can be used to pull the stream from the live source, then provide the live stream to the transcoding server for transcoding, and then provide the live stream transcoded by the transcoding server to the live cl...

Abstract

The invention discloses a method and device for creating a transcoding task, belonging to the technical field of Internet streaming media. The method includes: receiving the transcoding request of the target live stream sent by the streaming media server; determining the target load value corresponding to the target live stream according to the correspondence between the pre-stored original video parameters, target video parameters and estimated load values ; Obtain the actual load value of the current transcoding server, and calculate the total estimated load value of all transcoding tasks in the startup phase on the current transcoding server; if the target load value, the actual load value and the If the sum of the total estimated load values ​​is not greater than the preset load threshold, create a transcoding task and a corresponding transcoding process for the target live stream; otherwise, feed back a transcoding failure message to the streaming media server.

Description

technical field [0001] The invention relates to the technical field of Internet streaming media, in particular to a method and device for creating a transcoding task. Background technique [0002] Watching live broadcast is a mainstream form of entertainment at present. A large number of user terminals are equipped with live broadcast clients. Through the live broadcast client, users can play live streams provided by the live broadcast platform. Affected by various playback terminals and different user needs, the live broadcast platform often needs to transcode the live stream, that is, the live stream with the original video parameters is transcoded into a live stream with different purpose video parameters to meet different playback needs. Among them, the video parameter Including video format, bit rate, resolution, frame rate, etc. [0003] After the streaming server of the live broadcast platform pulls the new live stream from the live source, it can generate multiple t...
