      Overview

      This document describes how to use the live stream moderation feature via the Cloud Object Storage (COS) console. Moderation scenarios for live stream moderation include pornographic, illegal, and advertising content inspection. After you enable the live stream moderation feature, newly generated video streams from specific live domains will be automatically moderated. You can view real-time moderation results through the console or callback information.

      Prerequisites

      Supported live stream duration: less than 5 hours.
      Supported live stream resolutions: Up to 1920×1080 (1080p).
      Supported live stream protocols: Mainstream protocols such as RTMP, HLS, HTTP, and HTTPS.

      Operations

      1. Log in to the COS console. On the Bucket List page, select the required bucket to open the bucket management page.
      2. From the left sidebar, select Sensitive Content Moderation and then click Auto Audit Configuration > Live streaming moderation.
      3. Click Add Live streaming moderation configuration to open the live stream moderation configuration page, and set the following configuration items:
      Select a moderation policy: Choose the moderation policy you have configured. Different moderation policies correspond to different categories. You can customize the policy to personalize moderation based on scenes. Pornographic, illegal and advertising content moderation is supported, and you can select one or more detection scenes. You can go to Setting Moderation Policy to see how to configure a moderation policy.
      Risk library associated: Risk libraries associated with the moderation policy.
      Moderation scene: You can filter scenes configured in the moderation policy, such as pornography or advertising. You can select one or multiple scenes.
      Play Domain: The playback domain name used in your live stream services. We will pull out the video stream from this domain for moderation.
      Authentication key: If you have configured playback authentication in your live stream services, you need to enter the corresponding authentication key for your playback domain.
      Callback configuration: If callback is activated, corresponding live stream moderation results will be delivered to you. You need to choose the moderation type and content for callback while configuring the callback URL. For further details, see Live Stream Moderation Callback Content.
      Dedicated callback security configuration: To ensure the security of the CI callback information reception, we will generate a default moderation authentication token, which allows us to verify the source of the callback information. You can also customize and modify this token.
      4. If you have an ongoing live stream services, you need to specify the corresponding configurations with existing callbacks, to ensure your existing stream initiation and stream termination callbacks are unaffected. If you use the live stream service for the first time, you can skip this step:
      Existing Stream Initiation Callback: Specify your existing Live Stream Initiation Callback. We will forward the callback information to you.
      Existing Stream Termination Callback: Specify your existing Live Stream Termination Callback. We will forward the callback information to you.
      5. Click Save. The system will generate a callback address dedicated for live stream moderation. Specify this dedicated callback address for both your live stream initiation and termination callback in your CSS product. We will trigger the moderation automatically according to the stream initiation callback, and cease the moderation in line with the stream termination callback.
      Click to go to the CSS console
      6. After the preceding operations are completed, initiate a live stream to automatically commence the moderation process.
