CSS offers a live stream moderation feature. You can configure moderation templates in the console. Once the streaming domain is associated with the template, this service will obtain live screenshots and the audio during streaming, storing any non-compliant screenshots or audio data in Tencent Cloud COS. If the streaming domain is linked to the callback configuration, Tencent Cloud will send a request to the customer's server once a callback event is triggered during the live stream. Customer's server is responsible for handling the request. After verification, a JSON packet containing the moderation callback information can be obtained. This document provides instructions on how to create, bind, unbind, modify, and delete moderation configuration templates via the console.
Notes
Live stream moderation is a paid feature. Image moderation is charged 0.2294 USD per thousand images, while audio moderation is charged 0.0021 USD per minute. For more information, please refer to Live Stream Moderation.For more information, see Value-Added Services - Live Stream Moderation.
Screenshots or audio flagged during live stream moderation are stored in Tencent Cloud COS, which will generate storage costs. For pricing details, please refer to COS Product Pricing.
If your COS bucket allows public read access and has politically sensitive, pornographic, or other inappropriate content, to avoid the bucket being blocked, please delete the content first.
After a template is created, it can be bound with a push domain. For more information, see Live Stream Moderation Configuration. The association of the template is usually effective within 5-10 minutes.
Binding, modifying, or unbinding a template only affects new live streams and not ongoing ones. To apply new rules to ongoing live streams, you need to stop them and push them again.
To use a custom keyword library for image recognition, make sure "OCR" of "Image recognition" is selected. When OCR is on, the system will moderate the text in video screenshots. OCR-based moderation detects all non-compliant content regardless of the recognition policy configured.
Smart moderation can be performed on the live stream image, audio, and text content. Users can customize moderation policies and flexibly configure identification dimensions to ensure live streaming content compliance.
Prerequisites
You have activated the Tencent CSS service and added a push domain.
You have created a COS bucket. For more details, see Creating a Bucket.
Creating Live Stream Moderation Templates
1. Log in to the CSS console and choose Feature Configuration > Content moderation from the left navigation bar.
Note:
CSS stores video screenshots and audio data in COS buckets. Therefore, if it's your first time creating a moderation template, you need to create a service role and grant CSS read and write access to COS.
2. Click Create template.
3. A pop-up window will appear for you to grant CSS authorization to access COS resources. Click Authorize Now to go to the Role Management page.
4. On the Role Management page, click Grant. After authentication, CSS will have access to COS resources, and you can start using the live stream moderation feature.
5. After authorization, you will be redirected to the Create template page, where you can fill in the configuration items.

The audio segment duration can be 15-60 seconds. The default value is 15 seconds.
Audio text recognition

2. You can expand each category of Image Recognition and Audio Recognition to select sub-categories for moderation.

To use a custom keyword library for image recognition, make sure "OCR" of "Image recognition" is selected.
