Abstract

The invention provides a streaming media server with a multi-code-rate transcoding function based on a many-core processor. The streaming media server at least comprises a first processor unit and a second processor unit connected with the first processor unit, wherein the first processor unit is used for conducting processing including multi-code-rate transcoding and slicing on video demand source information and/or live source information based on configuration information from the second processor unit and outputting a processing result; the second processor unit is used for providing a live and video demand service based the information output by the first processor unit and the web technology and providing a human-machine interaction interface through which configuration personnel input the configuration information; the requirement for a live or video demand service is met; meanwhile, cloud transcoding with extremely low delay further can be achieved.

Description

technical field [0001] The invention relates to the technical field of streaming media, in particular to a streaming media server based on many-core processors and having a multi-code-rate transcoding function. Background technique [0002] In the era of increasingly widespread streaming media applications, streaming media transmission technology has undergone significant differentiation: on the one hand, real-time streaming technology represented by RTSP is attracting more and more attention from academia and industry; However, the progressive streaming transmission technology carried by HTTP is still widely used, and a dynamic transmission technology based on HTTP has sprung up suddenly, and has a tendency to catch up from behind. The characteristic of streaming media technology is that multimedia data is transmitted in real time and continuously in the Internet based on IP protocol in the form of stream. The client plays the received media data in the buffer in a way of ...
