CSS offers a live stream moderation feature, supporting the configuration of moderation templates through 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 charged feature. When enabled, the IA function is charged at 0.2294 USD per thousand images, while the AAS function is charged at 0.0021 USD per minute. For more information, please refer to Live Stream Moderation.
Screenshots or the audio flagged during live stream moderation and stored in your Tencent Cloud COS will generate storage costs in COS. For pricing details, please refer to COS Product Pricing.
If the access permission of the COS Bucket is set to public read, and the Bucket contains inappropriate contents related to pornography, illegal activities, or any other prohibited contents, it is recommended to go to the corresponding COS Bucket and delete the relevant images. This action can avoid COS Bucket being blocked, as the block may affect the use of it.
After creating the template, it can be associated with the streaming domain name. Refer to the Live Stream Moderation Configuration document for details. The association of the template is usually effective within 5-10 minutes.
Binding, modifying, or unbinding a template only affects the updated live streams and not ongoing ones. To apply new rules to ongoing live streams, you need to stop them and push them again.
For image recognition to be linked with a custom dictionary, the Image TAS strategy needs to be initiated, without which the linkage will not be effective. The image TAS by default, will perform OCR recognition and moderation on text in the screenshots from live screen. The default policy of Image TAS operates beyond the control of image recognition strategy and will audit all the non-compliant contents.
You have created a COS bucket. For more details, please refer to Creating a Bucket.
