ApsaraVideo Live supports stream ingest over the Secure Reliable Transport (SRT) protocol. SRT provides higher stability and lower latency than the Real-Time Messaging Protocol (RTMP). This topic describes how to use SRT for stream ingest.
Prerequisites
You have configured and associated an ingest domain and a streaming domain. For more information, see Getting started with ApsaraVideo Live.

SRT stream ingest and playback
SRT stream ingest: After you enable the SRT protocol, you can obtain an SRT ingest URL from the URL Generators in the console or by concatenating URL components.
Example of an SRT ingest URL: srt://demo.aliyundoc.com:1105?streamid=#!::h=demo.aliyundoc.com,r=/AppName/stream?auth_key={access token},m=publish
SRT playback: If you use SRT for stream ingest, playback is supported over the RTMP, FLV, HLS, and RTS protocols. SRT playback is not yet publicly available. To use this feature, contact your Alibaba Cloud account manager or Contact Us to enable it.
Example of an SRT streaming URL: srt://demo.aliyundoc.com:1105?streamid=#!::h=demo.aliyundoc.com,r=/AppName/stream?auth_key={access token},m=request
