1. API Description

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

This API is used to initiate processing tasks on a live stream. Features include:

Intelligent content moderation (porn detection in images, sensitive information detection, audio pornography detection);

  • Smart content recognition (human faces, full texts, text keywords, full speech, speech keywords, real-time speech translation, object recognition, and game tagging).
    Intelligent content analysis (clipping, highlights).
    Quality inspection (live stream format diagnosis, audio and video content detection (jitter, blur, low light, overexposure, black and white edges, black and white screens, screen glitch, noise, mosaic, QR code, and more), and no-reference scoring).
    Recording

Live stream processing event notification supports HTTP callbacks and also supports real-time writing to the message queue CMQ specified by the user. The user obtains the event notification result from the message queue CMQ. Meanwhile, if an output file exists during the process, it will be written to the target storage of the output file specified by the user.

A maximum of 100 requests can be initiated per second for this API.

We recommend you to use API Explorer
