Feature Description

Submit a video quality analysis task.

Authorization Description

When using with a sub-account, the ci:CreateMediaJobs permission is required. For details, see Cloud Infinite actions.
When a sub-account uses an asynchronous processing interface, the cam:passrole permission is required. The asynchronous processing interface performs COS resource read and write operations through CAM's "role". PassRole permission is used for role passing. For details, refer to Access Management > Write Operation > PassRole API.

Activating a Service

Using this feature requires enabling Cloud Infinite in advance and binding a bucket. For details, see Bind Bucket.
Use this feature requires enabling Media Processing Service in advance via console or API. For details, see Enable Media Processing Service.

Use Limits

When using this API, please first confirm the relevant restrictions. For details, see Usage Limits.

Fee Description

This interface is a paid service. Generated costs will be charged by Cloud Infinite. For detailed billing instructions, see Media Processing Fees.
