Period of time the company needs to do a live service, so I study a little cloud Ali live, live in it, the most important is the url of the authentication operation (push to verify the effectiveness of stream flow or pull), the Internet to find a lot of code, We have not found the demo java, so you write an article about podcasting recording, to facilitate future use and memory, where if there is an error, please indicate correct.
Ali cloud provides a live triggered a plug flow and play, you do not need to create a resource in advance, just add plug flow through the domain name and domain name for the record of the broadcast stream, and complete domain name resolution, authentication and other operations, the address can be manually splicing splicing rules to quickly obtain a corresponding multicast address and a plug flow stream address. This article describes the stitching method is not provided transcoded stream live event pushing address and multicast address of the stream.
Original article addresses: https: //help.aliyun.com/document_detail/87396.html spm = a2c4g.11174283.6.609.7eb3454eniwqXA?
What this means is that users do not need to create a resource in advance, when there is a live scene, directly generate a url and live through authentication can begin live coverage (see live is similar).
