Submitting Live Stream Moderation Job

Last updated: 2024-06-12 16:01:53

    Feature Overview

    This API is used to submit a live stream moderation job. The live stream moderation feature is async. You can submit a job to moderate your live streams, and then use the API for querying live stream moderation job result to query the moderation results.
    The API supports the following operations:
    Note:
    You can moderate various video live streaming scenarios, such as entertainment live streaming and online teaching.
    You can moderate various audio live streaming scenarios, such as voice chat room and online meeting.
    Automatically detect live streams and recognize non-compliant content in OCR, object detection (such as object, advertising logo, and QR code), image recognition, and audio recognition dimensions based on the deep learning technology.
    Get the detection results by setting the callback address Callback or calling the API for Querying Live Stream Moderation Job Result.
    Recognize various non-compliant scenes, including pornographic, illegal, and advertising information.
    Customize moderation policies based on different business scenarios as instructed in Setting Moderation Policy.
    Customize risk libraries as instructed in Setting Custom Risk Library to filter non-compliant custom content.

    Billing Details

    Live stream moderation is divided into live stream image moderation and live stream sound moderation as detailed below:
    Live stream image moderation: This service takes live stream screenshots through frame capturing for moderation.
    Live stream sound moderation: This service extracts sound from the live stream for sound moderation.
    Each moderation scene is billed separately. For example, if you choose to moderate one live stream in two scenes involving pornography and advertising, you will be charged twice.
    Calling the API will incur live stream moderation fees.
    Note:
    Live stream moderation does not incur frame capturing fees.

    Restrictions

    Supported live stream duration: No more than 5 hours
    Supported live stream resolutions: Up to 1920x1080 (1080p).
    Supported live streaming protocols: RTMP, HLS, HTTP, HTTPS.
    Default limit on the number of concurrent moderation channels: 10. When this limit is exceeded, an error will be returned.
