Embodiment Construction

[0053] Exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application may be embodied in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the application will be more thoroughly understood, and will fully convey the scope of the application to those skilled in the art.

[0054] First, the technical terms involved in the embodiments of the present application are explained.

[0055] Source stream: The video data that is directly pushed to the server without being processed in the live broadcast of the host.

[0056] Transcoding processing: Convert the compressed and encoded video stream into another video stream of different formats to adapt to different network bandwidths, different terminal processin...

Abstract

The invention discloses a live broadcast transcoding processing method, device and system, and relates to the technical field of the Internet, and the method comprises the steps: obtaining a room broadcast starting message of a live broadcast end; according to the room broadcast starting message, a first notification message is sent to a target edge cluster corresponding to the live broadcast end, and the first notification message is used for enabling the target edge cluster to perform preloading processing on a transcoding service; and transcoding the source code stream which is pushed to the target edge cluster by the live broadcast end by using the preloaded transcoding service. According to the mode, the transcoding service is loaded when the anchor user opens the live broadcast room, compared with the mode that the transcoding service is loaded after the live broadcast end succeeds in stream pushing in the prior art, loading of the transcoding service is advanced, the transcoding service can be immediately pulled to the source code stream for transcoding after the live broadcast end succeeds in stream pushing, it is not needed to wait for loading of the transcoding service, and the transcoding efficiency is improved. And the transcoding stream output speed is accelerated.

Description

technical field [0001] The present application relates to the field of Internet technologies, and in particular, to a method, device and system for live broadcast transcoding processing. Background technique [0002] With the development of Internet technology, webcasting has become a trend, and more and more users initiate and watch live broadcasts through mobile terminals. In order to pursue high-quality live broadcast effects, the host usually pushes high-bit-rate audio and video streams, which has high requirements on the bandwidth of the audience and the stability of network transmission. [0003] In the prior art, after the live broadcast end pushes the audio and video stream to the server, the audio and video stream is transcoded using transcoding technology to reduce the bit rate, and the transcoded stream produced by the transcoding is delivered to the viewing end for playback. However, in the prior art, the transcoding service is started after the stream is pushed...
