1. API Description

Domain name for API request: mps.tencentcloudapi.com.

This API is used to parse the content of an MPS live stream processing event notification from the msgBody field in the message received from CMQ.
Instead of initiating a video processing task, this API is used to help generate SDKs for various programming languages. You can parse the event notification based on the analytic function of the SDKs.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
